Any type of transmission technique that carries some data channels over a common wire refers to broadband.DSLservice, combines separate voice and data channels over a single telephone line, is one of the case of broadband technology. Broadband constitutes any form of high-speed Internet access using this transmission technique in home networking. Voice fills the low end of the frequency spectrum and data fills the high end in DSL.

General broadband Internet technologies are both DSL and cable modem. Devices that support both DSL and cable are broadband routersand broadbandmodems.Fiber (FTTH)and fixed wireless are other types of home broadband. Can bear the network bandwidth at least 256Kbpsfor connections in one direction is a general guideline to meet the criteria as a broadband Internet service.

The term broadband generally refers to high-speed Internet access that faster than the typical dial-up access and that is always on. Broadband is dissimilar from dail-up where broadband service supplies higher-speed of data transmission. The transmission "pipeline" will allows extra content to be carried through it. On the other hand, broadband offers access to the highest quality Internet services such as streaming media, VoIP (Internet phone), gaming, and interactive services. Many of these current and newly-developing services require the transition of large amounts of data that may not be technically practical with dial-up service. Therefore, broadband service may be ever more necessary to access the full range of services and opportunities that the Internet can offer. Broadband is always on so there is no need to reconnect to network after logging off. For this reason it does not block phone lines. Broadband has less delay in transmission of content.


  • Broadband in Malaysia:

Malaysian broadband users are growing in numbers every day.According to an AC Nielsen survey in 2009,Malaysians ranked third in the global ranking of the Digital media consumers,who spend over 20 hours a week watching streamed or downloaded content from the Internet.It is undeniable that there is a growing need from Malaysians for a better broadband service.The reason why broadband has become a necessity is because moving to tne web-o-sphere is inevitable for any corporate entity today.The broadband and Internet opens up a host of business opportunities,options and solutions allowing market expansion and growth.Broadband enable Malaysian to communicate.They can communicate via e-mail as well as other social networking sites and the Internet sometimes functions as student's virtual classroom and for student's course work.

Broadband service is an important need of companies.They could suffer losses as slow services would hinder the online experience.As Malaysian are already in the IT world, Malaysian don't just need a broadband service,but need one that is better.As Malaysia is develops,the usage of the internet becomes even more vital as Malaysia has a high number of users,Internet service providers should cater the best for the users.Broadband service is a necessity for the corporate world as well as personal use.Internet is the integral part of the modern world.It is time for Malaysian to enjoy something that they need less hassle as technologies have allowed room for improvement in the Internet service.

  • Malaysia National Broadband Initiative (NBI).

The National Broadband Initiative is the government's initiative to provide broadband service to the whole country and highspeed broadband with high economic activities.The target is to connect 50 percent of Malaysian households to broadband by 2010.This measurement on household will futher be enhanced by considering other elements that would better reflect the use of broadband by the citizen such as taking into account cellular mobile penetration,PC ownership,use of internet in Community Broadband Centres,office and school.Under the NBI,highspeed broadband service will be 10Mbs and below.The era of slow Internet (dail-up) connection will be over and of course broadband will transfer people's lives.

The aim is to narrow the gap between the "haves" in urban areas,and "have-nots" in rural areas,often referred to as the digital divide.This imbalance in communication access can have social ramifications if not address at the nation al level.In Malaysia,the push to narrow down the gap between the urban and rural has been entrusted to the Malaysian Communications and Multimedia Commision (MCMC).MCMC is mandated to work towards narrowing the inequalities of access that exist in underserved areas and populations.MCMC has overseen project that have steadily reduced the number of areas that were not served by telecommunications services.

  • Speeding Up Malaysia's Tranformation:

ICT and Internet are recognised as vital support services and platform in driving all other sectors in the social economic growth of nations along the lines of knowledge based and Digital economy.As a logical follow-through of the ICT development for the country following earlier related initiatives in computerization,upgrading and Digitalisation of the communications networks,the introduction of the multimedia super corridor (MSC) in the 1996,the advent and the phenomenal take up the Internet and IP-based technologies,the nation has indeed stepped up with the introduction of NBI in October 2004.

The strategy adopted under the NBI was to address the availability of broadband as an engine of growth and need to bridge the Digital divide with the objective of providing equitable access to communication services.

More importantly ,the citizen have access to basic amenities to basic amenities through the Internet such as health and emergency services,schools, government and local services and of course other consumer services.

Under NBI, rural communities will be connected to broadband services through the Community Broadband Centre located throughout the country.The competitive environment generated by the communications and multimedia industry has propelled the widespread adoptation of broadband through availability of affordable package and choices to the Malaysian public hence increasing the connectivity of the citizen and reach to market.

  • Moving Towards Innovation Economy:

With broadband,Malaysian will have access to the Internet,information and services that can be capitalised to improve socio-economic standing.Rural communities in the hard-to-reach places especially,can use broadband to gather useful information and access to services at their fingertips,without having to go far and wide.Broadband is expected to have tangible impact on Malaysia's Gross Domestic Product (GDP).It will increase national competitiveness and foreign direct investments plus enable a knowledge-based and innovation driven economy.NBI targets 50 percents households to get broadband service by end of 2010.It is a government initiative to provide infrastructure in line with the new economic model,aims to transform Malaysia into knowledge based society generating the high income economy.

In overall term, it aims to improve,the nation's socio-economic standing globally.As the NBI will provide the service to the whole country,so every one will be entitled to the broadband service including those in the rural areas.This access to knowledge could be extended to family members and communities which in turn will enrich the nation.

With the NBI, economic innovation can also help bridge the socio-economic gap.The broadband service,has leveraged the small medium enterprises and entrepreneurs (SMEs) to market their products to much larger networks via the world wide web.Although there are concerns usage Internet will expose the people to negative influences,but to curb it, Internet also provides the education and knowledge at the fingertip.

Malaysia's government on its part will take proactive action to prevent negative elements to stringent monitoring and enforcement of laws.Just as much as the country will get the economic benefits there are other aspects that Malaysia can gain from the improvement and enhancement of the broadband service too.The advantage of broadband service are limitless.


Wireless is very essential.Wireless networksis presenting a network having no wires as wireless network can connect your computer to a network using radio waves and so you can move your computer wherever easily. Wireless network has made a network very portable because of digital modulation, adaptive modulation, information compression, and access multiplexing. IT Consulting group with IEEE certified 802.11b technology, introduced wireless networks. With wireless networks, you will experience the privacy and personal computer security extra than before. Air is the medium for the wireless network. A wireless networks have offering very flexible, roaming, high standard and low cost. There are different types of wireless network such as wireless LAN, wireless MAN, and mobile devices network. 2.2.1

  • Types of Wireless Networks and network usage:

Imagine the world is completely without wire. It must be amazing and very comfortable. Without using any wires, by means of communication, a wireless network able to two or more than two computers.Depends on the technology which is using, wireless networksutilizes spread-spectrum orOFDM. User able to travel about within a wide coverage area and they still can be connected to the network with wireless network. There are different types of wireless networking such as wide area network, local area network and personal area network but the most common are of two which are WLAN(Wireless Local Area Network) and WMAN(Wireless Metropolitan Area Network).

The usage of wireless networking greater than ever gradually because it has influenced vital impact on the world therefore its uses have substantially developed. Through wireless networks, you can send information over the world using satellites. As wireless network utilize to commune significant information speedily, wireless networks used in emergency services like police department nowadays. It doesn't matter to be in a small office or across the world, the growth of wireless network increasing develops both in people and businesses to send and share data rapidly. An extra very important exercise for wireless networks is as a cheap and fast way to be linked to the Internet in regions especially where telecom transportation is insufficient and no source for communication. You can get access to other network resources like Library Online System to make use of wireless networks because to move your laptop anywhere is very easy nowadays. The use of printer, file sharing and other documents with high security is also can be implement with wireless network.



Commonly, wideband of frequencies is available to send out information is called broadband refers to telecommunication in which a. Because a wide band of frequencies is available, information can be multiplexed and sent on many different frequencies or channels within the band concurrently, allowing more information to be transmitted in a given amount of time (much as more lanes on a highway allow more cars to travel on it at the same time). Related terms arewideband(a synonym),baseband(a one-channel band), and narrowband(sometimes meaning just wide enough to carry voice, or simply "not broadband", and sometimes meaning specifically between 50cpsand 64Kpbs).

Meanwhile wireless mean wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path. Wireless is better than wired cable because wireless technology is portable, has premier performance and flexible configuration and integration.

Both provider and user want to improve the coverage.So that,the signal has good indoor penetration for residential and enterprise applications fast rollout and wide coverage.For the wireless broadband company they want to improve and achieve better capacity which can support sufficiently high number of simultaneous users.Call quality is one of the factor that both user and provider want to improve so that it will have low latency, high data-rate and high reliability and uptime.Generally user want to have affordable, differentiated tariff packages that suit different user needs plus low CPE (customer-provided equipment )price. Improving services is also essential so that user has opportunity to replace existing fixed line voice services and upgrade anything regarding their broadband without any complicated policy.Beside that, technology is based on open standard to enable economic of scales and wide adoption.The roadmap of the broadband also must be well defined to enhance technology or broadband services. Traffic management must achieve 80% of the bandwidth for 80% of the users (and not 20% of the users). Broadband should have sufficient spectrum for large-scale deployment & long-term growth.

Wireless broadband needs to deliver something that is affordable by the user with low cost CPE, low access price, and attractive value-added services -broadband data and voice.Broadband which is easy to install, simple installation and no need for phone lines ("broadband on the go") plus best quality which has quick connection and consistently good performance.Finally user want to has portability which has pervasive coverage (including indoor) and always connected.

  • WiMAX:

Also known as IEEE 802.16, WiMAX is a wireless digital communications system that is intended for wireless "metropolitan area networks". In Malaysia,P1WiMAX is the company that use this technology to implement wireless broadband.WiMAX can give broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. On the contrary, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m).

The bandwidth and range of WiMAX make it suitable for connectingWi-Fi hotspotsto the Internet, providing a wireless alternative to cable andDSLfor "last mile" broadband access. Besides providing data, telecommunications andIPTVservices (triple play),WiMAX also providing a source of Internet connectivity as part of a business continuity plan. That is, if a business has both a fixed and a wireless Internet connection, especially from unrelated providers, they are unlikely to be affected by the same service outage. Finally WiMAX provides portable connectivity.

  • WiMAX technology:

Extending broadband wireless access to new locations and over longer distance,WiMAX (802.16) is the next stage to a broadband .In the wireless world,WiMAX reducing the cost of bringing broadband to new areas. WiMAX (802.16) technology provides wider range and bandwidth than the other available or forthcoming broadband wireless technologies such as Wireless Fidelity (Wi-Fi). It offers a wireless option to wired backhaul and last mile deployments that use cable modems, Data Over Cable Service Interface Specification (DOGS1S), Digital Subscriber Line technologies (DSL), T-carrier and E-carrier (Tx/Ex) systems and Optical Carrier Level (OC-x) technologies.

Based on the typical connection to the public wireless networks by using optical fibre, microwave link, cable or any other high speed connectivity, the backhaul of the WiMAX (802.16) is created. Mesh networks, Point-to-Multi-Point (PMP) connectivity is also used as a backhaul in a few cases. WiMAX (802.16) should use Point-to-Point antennas as a backhaul ideally to join subscriber sites to each other and to basestations across long distance.

A Subscriber Station (WiMAX CPE) typically serves a building using wired or wireless LAN.Using Non-Line-of-Sight (NLOS) or LOS Point-to-Multi-Point connectivity,a WiMAX basestation serves subscriber stations; both connections is referred to as the last mile communication.WiMAX (802.16) should use NLOS Point-to-Multi-Point antennas to connect residential or business subscribers to the WiMAX Basestation (BS) preferably.

  • Type of WiMAX and receiver:

TheWiMAXfamily of standards (802.16) focus on two types of usage models which are afixed WiMAXusage model and amobile WiMAXusage model. Thefixed WiMAXserves the stationary and pedestrian classes meanwhile amobile WiMAXnetwork access system is one that can address the vehicular class

Until now one of the important restrictions to the widespread acceptance of WiMAX has been the price of WiMAX CPE (WiMAX Receiver). This is not only the price of WiMAX CPE (WiMAX Receiver) itself, but also that of installation. The idea of a self-installed WiMAX CPE (WiMAX Receiver) has been difficult for Broadband Wireless Access (BWA) from the beginning, but with the arrival of WiMAX technology this issue seems to be getting resolved. In the past, BWA has been predominantly Line Of Sight (LOS), requiring highly skilled labour and a truck role to install and provide a service to customer.

  • WiMAX design:

Internal devices and a WiMAX tower are the contents of aWiMAX basestation. Some other and environmental issues bound the limits of WiMAX range to 10 km or 6 miles. A WiMAX basestation can normally covers the area of about 50 kilometres or 30 miles radius. The WiMAX basestations would use the media access control layer defines in the standard and would allocate uplink and downlink bandwidth to subscribers according to their requirements on real time basis. Any wireless user within the coverage area would be able to access the WiMAX services.

  • WiMAX in future:

Compare to the typical Wi-Fi hot spots, WiMAX technologycan make high speedwireless broadbandInternet services available to much larger areas. Greater than the physical distance limitations of Wi-Fi hot spots or DSL, WiMAX technology can also be used to interconnect existing Wi-Fi networks.

WiMAX Technology can play a significant role in helping service providers to deliver converged services that can be accessed using a broad range of devices on a wide variety of networks.WiMAX implementations can provide a wireless range of up to 30 miles or 50 kilometres.

By given different capabilities while allowing for seamless integration at the technical level, 3G and WiMAX Technology solutions fit well together. To become highly spectrally efficient, 3G technologies have evolved over many years allowing operators to take benefit of costly spectrum dedicated to mobile services. 3G CDMA technologies such as W-CDMA and CDMA 2000 1xEV-DO provide high through puts in low bandwidths as 5 MHz and 1.25 MHz, respectively.

  • Treat to WiMAX and security:

WiMAX security, stability and quality of service are some of factors involved in declining the WiMAX technology performance. In this subchapter author is going to discuss the threats involved in WiMAX.

WiMAX basestations andWiMAX Customer Premise Equipments are the content of the WiMAX wireless access network. The WiMAX basestations provide network add-on to the WiMAX CPEs. AWiMAX Customer Premise Equipment(WiMAX CPE) selects the one which offers the strongest signal as a servingWiMAX basestation. At this point, aWiMAX basestationand a collection of servedWiMAX Customer Premise Equipments (WiMAX CPE's) play the role of system while the subscriber plays the role of the user.

TheMedium Access Control(MAC) layer andphysicallayer are two of most important layers of protocol architecture of WiMAX Technology. Common Partsub layer is the essential part of WiMAX technology layered architecture.MAC ProtocolData Units (PDUs) are constructed, connections are established and bandwidth is managed in this layer. With the Convergence layer, the Common Part (CP) exchangesMACService Data Units (SDUs). Tightly integrated with Common Part is thePrivacy sub layer. With the Physical layer ,the Security sub layer exchanges MAC PDUs. The Convergence layer adapts units of data of higher level protocols to the MAC SDU format, and vice versa. Sorts the incomingMACSDUs by the connections to which they belong by The Convergence layer. Received and transmitted through coding and modulation of radio frequency signals, ThePhysical layeris a two-way mapping between MAC PDUs and Physical layer frames.

Type of treats in WiMAX are Rouge Basestation,DoS (Denial of Service) Attacks,Data Link-Layer Threat,Application Layer Threat,Physical Layer Threat,Threat, Authentication, Key, Theft, Water and finally Black Hat Threat.

The primaryWiMAX securityconcerns from the point of view of an end user are privacy and data integrity. Users need guarantee that no one can eavesdrop on their sessions and that the data sent across the communication link is not tampered and usually achieved through the use ofWiMAX network encryption.

An importantWiMAX securityconsideration is preventing unauthorized use of the network services. From the service provider's point of view, using strong authentication and access control methods. The service provider's need to prevent fraud should be reasonable against the difficulty that it may impose on the user. Thephysical layer, and theprivacy sub layer are the example of authentication and access controlthat can be implemented at various levels of the network.

  • Multiple-input multiple-output communications(MIMO) technology onWiMAX:

The use ofMultiple-input multiple-output communications(MIMO) technology onWiMAX, which is the technology brand name for the implementation of the standardIEEE 802.16 is called WiMAX MIMO.

Multiple Input and Multiple Output or MIMO, refers to the technology where there are multiple antennas at the mobile device and multiple antennas at thebasestation. Typical usage of multiple antenna technology includes laptops with two antennas, cellular phones, as well asCPEdevices with multiple sprouting antennas.

The 802.16 specification also supports the use of four antennas. Three configurations are supported which are WiMAX four antenna mode 1, WiMAX four antenna mode 2 and finally WiMAX four antenna Matrix C mode.

For WiMAX four antenna mode 1,with rate equal to 1, using four antennas, data is transmitted four times per symbol, where each time the data is conjugated and/or inverted. This does not change the data rate, but does give the signal more robustness and avoids sudden increases in error rates.Meanwhile for WiMAX four antenna mode 1 with rate equal to 2, using four antennas, the data rate is only doubled, but increases in robustness since the same data is transmitted twice as compared to only once with using two antennas.Finally,the third configuration that is only available using four antennas is Matrix C, where a different data bit is transmitted from the four antennas per symbol, which gives it four times the baseline data rate.



An enhanced3G(third generation)mobile telephonycommunications protocolin theHigh-Speed Packet Access(HSPA) family, also coined 3.5G, 3G+ or turbo 3G, which allows networks based onUniversal Mobile Telecommunications System(UMTS) to have higher data transfer speeds and capacity is called High-Speed Downlink Packet Access(HSDPA). Present HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.0Mbit/s. withHSPA+,Further speed increases are available, which provides speeds of up to 42 Mbit/s downlink and 84 Mbit/s with Release 9 of the 3GPP standards. HSPAEvolved is the second phase ofHSDPAis specified in the upcoming 3GPP release 7.

  • HSDPA Technology:

HARQ(Hybrid Automatic Repeat ReQuest) used the concept of "incremental redundancy". With "incremental redundancy" retransmissions contain the relative to the original transmission which is different codings of the user data. The user device saves it after a corrupted packet is received. An error-free packet can occur with the combination of the sum of the error transmissions, even if the retransmitted packet(s) is itself spoiled. With subsequent retransmissions, user will combines it to create an error-free packet as fast and efficiently as possible.

With channel-dependent scheduling, the HS-DSCH downlink channel is shared among users to take benefit of good channel conditions to fully use of existing radio conditions. To determine for each user how much data they should be attempted and for the next 2 ms frame, which users will be sent data, The Node B uses this information arriving from all user devices. High downlink signal quality is reported as extra data can be transmitted to users. 500 times per second periodically transmission for each user will be the sign of the downlink signal quality.

Network bandwidth and thus the amount of the channelization code tree, due to HSDPA user are indomitable by the network. In this part, a tradeoff between bandwidth allocated for HSDPA users and non-HSDPA data users. While the network is operating, it can be altered. As the allocation is "semi-static", it cannot be modified on a frame-by-frame basis.

One of the advantages that is the improving the round trip time for applications, decreasing on latency as well as better data rates. For the next 2 ms frame, which users will get the data is determine by Node B. Data may be sent to the users at the same time, via different channelization code for a specified 2 ms frame. The highest number of users to get the data on a given 2 ms frame is decided by the number of allocated channelization codes totally not similar with CDMA 1xEV-DO, where at a time, data is transmitted to only one user.

In release 5 UMTS networks, HSDPA happen to be part of the family. There are different progresses of HSDPA. In excellent radio conditions the introduction on 16QAM modulation will make the data throughput rates better by roughly double of QPSK although QPSK is the initial modulation scheme. Usually,1.8 Mbit/s peak data rates will be offered by QPSK with 5 Code allocation. 16QAM with 5 Codes will raise this to 3.6 Mbit/s. In theory, 10.8 Mbit/s will be the highest throughput in HSDPA. additional codes for example 10 can be implemented to make these data rates become better or extend the network capacity throughput significantly. Now,HSDPA seem to have enhancement on on the uplink with a new bearer of 384 kbit/s compare to the previous maximum bearer which was 128 kbit/s.

Comparison of HSDPA's speed with other technologies:

Terminating at the Node B, other physical channel beside the Signalling Control Channel is a reverse channel. The reverse channel will bring current channel quality of the user and acknowledgement information. So the total is two new physical channels that are introduced, along with the HS-DSCH channel.To attain peak data rates of 14.4 Mbps, phase one introduces new basic functions. In the Node-B, High Speed Medium Access protocol (MAC-hs),High Speed Downlink Shared Channels (HS-DSCH) and the adaptive modulation QPSK 16QAM are recently launch.

In the second phase of HSDPA is expected to reach data rates of up to 28.8 Mbps in 3GPP release 6 at this time. Multiple Input Multiple Output (MIMO) and beamforming are the antenna array technologies that will be introduced. in a beam to the user's direction, beam forming will be focuss the transmitted power of an antenna.For increasing the power, one can understand what actually is a beamforming and the get noted that transmission power of the basestation sector will be the limiting resources. Both at receiving and sending side, MIMO implemented multiple antennas.Air interface will be focused in the third phase of HSDPA. With Orthogonal Frequency Division Multiplexing and advanced modulation schemes, it will bring in a new Air Interface. Anywhere WCDMA is deployed, 3G protocol can become the proceeding of 3G although most countries not offer it. Data rates of up to 50 Mbps in phase three of HSDPA.

In conclusion, with HSDPA installed in thecell phones or using the HSDPA to use the wireless technology,users can experience the advantages of greater data capacity. HSDPA offers the base to reach the higher data capacity and high speed for better servive of UMTS. An HSDPA feature also supportst-mobile phonesthereby increasing its efficiency. HSDPA access can be instated insamsung phones,lg phonesand phones of the similar calibre.

In Malaysia,IZZI Broadband company provide this technology to market their broadband.

Just plug it in, turn it on.iBurst™ is easy to obtain and use.In addition,iBurst™ has high-speed connectivity.Nowadays, individual connection speeds of up to 1 Mbps and with protocol support for up to 16 Mbps,the connection will up to 2 Mbps in the coming system release.Access through standard devices, the iBurst™ wireless modem connects to standard IP-enabled devices like laptop and desktop PCs and PDAs.Open access is available with iBurst™ technology where users' favorite Internet content, applications and services, including email,corporate VPNs, VoIP, video streaming, on-line gaming, can be accessed by the user.

A seamless broadband Internet computing and communications will be experienced with the iBurst™ system. Today, peak data rates are in excess of 1 Mbps per user, with 2 Mbps coming in the future. 16 Mbps per user can be supported by the iBurst™ protocol itself.The iBurst™ system provides high-speed when access to the Internet, virtual private networks (VPNs) and other IP networks from the widest possible range of devices, including laptop computers and PDAs. From the end user's perspective, users need not adapt their computing habits, applications or devices to match their access method of the moment with the iBurst™ system. This is contrast to where the access method forced the choice of a particular device for example, a cellular phone.

High data rates, massive capacity and minimal capital and operating expenses are the result of the iBurst™ technology. The iBurst™ system offers the most cost-effective, spectrally efficient broadband mobile access network available from the core network operator's perspective. Open data networking standards and equipment used in the wired backhaul and core transport networks, providing the operator with flexibility in networking technology and vendor and device selection. The access platform is designed to create a compelling wholesale business opportunity for network operators and to carry the subscriber traffic of many service providers. Today it is a direct extension of the wired broadband wholesale infrastructure employed by major operators. These operators are provided with an additional means to derive returns on that investment by the iBurst™ system.

The iBurst™ system enables access to a new class of wireless customers using the same hardware, service and management bases as for its wired customers, from the service provider's perspective. Either through Point-to-Point Protocol (PPP) over Layer 2 Tunneling Protocol (L2TP) or via pre-terminated IP sessions, iBurst™ network sessions are able to deliver to service providers. To support iBurst™ network subscribers, most medium- and large-scale service providers already have the necessary hardware and software. A user's experience is that of connecting directly to the service provider, when connecting to a service provider via the iBurst™ system. Customers have a direct relationship with their Service providers, including billing and branding.

To support the iBurst™ access system, wholesalers of wired access already have the necessary wired infrastructure. Extends the wired broadband service architecture outlined above directly is the iBurst™ service architecture. Standard end-user service provider tools can be used to terminate, manage and provision the iBurst™' system's broadband wireless users. Additionally, any end-user device laptop, PDA and other gadgets supporting the pervasive PPP access protocol and modem can be used for access if equipped with an iBurst™.

  • Transportable iBurst™ Basestation Platform:

nbsp;The best thing about iBurst™ technology is the basestation can move from one place to another.It is called Cellular On Wheel (COW) and it already implement in iBurst™ to give benefits to the user.This is because if there is unexpected problem occur such as flood,the COW and be transport to the other place yet it still can receive information and transmit the signal.So that the connection with the flooded area will not be interrupt.So iBurst™ is the technology that will give an ease when there is any emergency happen.

It also can be use in the military base as the military base is usually at the rural place and with no other people staying there where the signal is very difficult to receive.So COW can be the solution as the basestation is transport form the main city to the rural place by airplane or truck so that the rural place will not be disconnected to the main city.When the they want to move the military base they can bring together the COW.This will cut down cost as they do not has to build the new basestation when they move to other place.

The bridge between the wireless and wired portions of the network is called the iBurst™ basestation. The basestation is an access aggregation device that aggregates the PPP session data of the end-users that it is serving, viewed from the wired network. It plays an analogous role to a Digital Subscriber Line Access Multiplexer (DSLAM) in a DSL network in this sense. To manage the iBurst™ basestation, both Simple Network Management Protocol (SNMP) and a command-line interface, access the same underlying management and monitoring data.The data are comprised of industry-standard SNMP Management Information Bases (MIBs).

An enterprise MIB is to control and monitor the iBurst™ radio interface.This ensured highest possible spectral efficiency, and hence lowest access infrastructure costs for the iBurst™ mobile broadband application.The characteristic of iBurst™ basestation are multi-mode backhaul (microwave, satellite, fiber),self-Propelled, self-Powered.Besides,iBurst™ basestation also have variety of tower heights from 17m (50ft) to 60m (200 ft) with high top and wind load resistance and it can withstands 160 Km/h (90 mph) winds in operation.iBurst™ basestation compatible with all roads.Other characteristic of iBurst™ basestation are it can operate in less than 20 minute after arrival on siteower-top and the basestation is electronics capable.It has 40 + similar units in operation at cellular networks worldwide and several hundred towers in operation in armed forces and mobile operations worldwide for communications and surveillance.

  • iBurst™ service:

By extending access aggregation architectures to mobile broadband access, iBurst™ system provides an end-to-end IP connection for users. To support iBurst™ end users, network and service providers can control existing equipment, tool and content bases best of the wireless and wired worlds will be experienced by the end user .The broadest range of applications and end-user devices, coupled with the high data rates and freedom to move will achieve by user.

Upon a wide range of lower-level services implemented in the network operator's and service providers', networks iBurst™ system are built."FCAPS" for fault, configuration, accounting, provisioning and security refered to these lower-level services .The "Services" section of the present document focuses on four key services which are billing, roaming, service levels, security and IP address management as provided by both the network operator and the service provider.

Connection with independent uplink and downlink peak rates subject to a certain level of oversubscription is a basic end-user service offered in the initial implementation of the iBurst™ system. Service of a service provider's Gold level might be 1 Mbps/345kbps (down/up) with 20x over-subscription, while 384 kbps/128 kbps (down/up) with 20x over-subscription is for the Silver level of service might be as the example. To effect the peak uplink and downlink rate limits specified in that user's RADIUS profile,the LNS terminating a user's PPP session performs the necessary throttling. DSL and cable services also used this same notion of service. It provides significant flexibility to network and service operators in engineering the tradeoff between network capacity, service quality and service cost and the model is familiar to consumers.

The access and transport network is engineered with one level of over-subscription typically. This is done with a separate level of over-subscription selected for the links between that network and the service provider's equipment. The product of those two numbers will be the advertised level of over-subscription.

  • IBurst™ advantages:

Allows uninterrupted, high speed and truly mobile Internet connectivity on-the-go become the best about IBurst™ itself.Reduced spectrum requirements, minimizing up-front capital expenses related to spectrum ownership and radio elements in both basestations and user terminals is one of the spectrally efficient systems other than reduced infrastructure requirements, minimizing capital and operating costs associated with basestation sites, translating into reduced costs per subscriber and per covered population element. Spectrally efficient systems also have high capacity, maximizing the system throughput and end-user experience even under load.

Profound effect on wireless system economics is the basestation range. By determining the number of basestations required to cover an area, it will affects capital expenditures. Operating expenditures by determining the number of sites and backhaul links connections from the individual basestations to the network core that must be hired is also affected. The coverage area of its basestations by approximately a factor of four higher than other systems offering comparable aggregate data rates will be increased by iBurst™ system's adaptive antenna technology. The result is a scalable wide-area broadband access system with unmatched economics, combined with the system's spectral efficiency. The terrain, building density, the type of subscriber device and antenna used, and so forth affected The specifics of basestation range in a given iBurst™ deployment . iBurst™ systems have demonstrated high user data rates at ranges of 1-2 km in the most challenging case like urban environment and over 12 km in suburban environments with a desktop modem and small (indoor) patch antenna as practical reference points. Key component of the cost structure of wireless systems is a the acquisition of spectrum, and two key features of spectrum have great impact on that cost the spectral efficiency of the wireless system and the type of spectrum required to implement the system. The iBurst™ system is especially efficient in its use of spectrum and requires far less of it per unit of delivered service than other technologies, as mentioned earlier. A fully capable and commercially viable iBurst™ system can operate in much less spectrum than other wireless technologies require to provide the same amount of capacity where it functioned little as 5 MHz of unpaired spectrum with a total of 20 Mbps of net usable throughput per cell in that amount of spectrum (in the omni configuration, with up to 80 Mbps in a sectorized cell).
