Stephen E. Arnold stated No one paid me to create a note card as a blog post. I suppose I report this type of research-like action to the National Science Foundation, where the cutting edge is in the future". This is where I think technology is headed. It's the cutting edge into the near future. More people are using their cell phones to do everything today. The average business man depends on mobile technology to function though the day. In this paper I will be introducing the different types of mobile technology that I as a student, mother, and part business owner use in today's technological world.

What is mobile technology and what are the benefits? Mobile technology is exactly what the name implies- technology that is portable. It is a collective term uses to describe the various types of cellular communication technology. Mobile CDMA technology has evolved quite rapidly over the past years. Since the beginning of the millennium, a standard mobile device had gone from being no more than a simple two-way pager to being a cellular phone, GPS navigation system, an embedded web browser, and Instant Messenger client, and a hand-held video gaming systems. Many experts argue that the future of computer technology rests in mobile/wireless computing.

'third and fourth generations (3G/4G), global systems for mobile communications (GSM) and general packet radio service (GPRS) data services-data networking services for mobile phones

So what is the benefit of mobile communications? Mobile computing can improve the service that is being offered to the consumer. Here is an example. A mother has two children, both are home today from school with the flu, the mother has an important meeting today with a promotion on the line. Now the mother cannot locate a relative to watch the children nor does she have enough money for a babysitter, so she is able to connect via her wireless router to connect to her virtual private networks from her office, connect live via her webcam for a video conference all from the comfort of her living room. This is how mobile technology can offer solution to a single family home. Another benefit for mobile communications is having the flexibility of working with networking hot spots that is being provided in public areas that allow connection back to the office network or the internet. This growth of cloud computing has also impacted positively on the use of mobile devices, supporting flexible working practices by providing service over the internet.

Now there are drawbacks to mobile communications. There are costs involved in setting up the equipment and training depending on the services. Mobile IT devices can expose valuable data to unauthorized people if the proper precautions are not taken to ensure that the devices, and the data they can access, are kept safe.

With all of this current technology we must ask ourselves what's new to the future? Well I search and searched Google and saw an article that was posted on www.computerworld.com stating there are 13 future mobile technologies that will change your life. This question was posed to a group of industry analysts' futurist and executives for key vendors, a group grounded in reality, not fantasy. They suggested that 13 technologies that will provide dramatically better mobile access, better devices and better applications. Some of these life changing technologies are just around the corner while others years away. It seems that the future will offer:

Better access - Advanced applications and devices require fast, easily affordable access, but today's 3G cellular data service remains expensive and, with typical speeds between 400Kbit/sec. and 700Kbit, slow. That's about to change, however, and the pace of change will remain rapid into the foreseeable future.

Disruption 1: Mobile WiMax - Sprint Nextel Corp. said it will launch its mobile Xohm WiMax network commercially in a handful of cites next spring with more cities added throughout 2009 and beyond. It has the potential to be a game-changer, some experts say.

Disruption 2: Multihop relay networks - Some researchers and futurists believe that mutlihop relay networks will eventually supplant technologies such as WiMax and LTE. With these networks, wireless signals will route themselves through a series of access points. Like the internet itself, the route that the data takes is variable, depending on conditions.

Disruptions 3 and 4: Femtocells and fixed -mobile convergence - Both these technologies enable you to have one phone and one phone number with which you can communicate from virtually anywhere. A femtocell looks a bit like a Wi-Fi router but performs the same function in the home or office as cellular base stations that sit in brick buildings at the base of cell towers. That is, they communicate directly with your cell phone and carry the signal to the larger network via a broadband line such as DSL or cable. Sprint is offering femtocells on a trial basis, to customers in Denver and Indianapolis and charging $15 a month for individuals or $30 for a family. Subscribers can then make as many local and national calls as they want.

Better devices - With faster, more ubiquitous access, devices can start to radically change. "Imagine a Bluetooth headset in your ear but that's the phone," said Dan Burrus, CEO of Burrus Research Inc. and author of the book Technotrends. "And it will continue to get smaller from there until it's implanted in your ear. You ask for whatever you need [with your voice] and it will tell you the answers."

Disruption 5: Miniscule, less power-hungry mobile chips. Chip vendors have been talking about smaller, more powerful and less power-hungry chips for a long time. Now, development of such chips is likely to accelerate.

Disruption 6: Wireless USB and ultra wideband. These short-range, wireless cable replacement technologies are starting to be available. Admittedly, they lack the gee-whiz factor, but they eventually will make life much easier for mobile users.

Disruption 7: Nearly flawless speech recognition. Another mobile input application on the horizon is better speech recognition, which will be enabled by more powerful mobile chips.

Disruption 8: Foldable displays and e-paper. Vendors such as Philips and Fujitsu Computer Systems Corp. have been publicly showing foldable and e-paper displays for mobile devices. Both will enable tiny devices to display data clearly on easily stowed screens.

Disruption 9: Centralized storage. Fast, ubiquitous wireless access will enable centralized storage on remote servers, which will have a series of important ripple effects.

Disruption 10: Unified communications. Huge technology players such as Microsoft Corp. and Cisco Systems Inc. are pushing for the ability to tie together all forms of communications, including landlines and the various types of wireless. It's a compelling vision that is a stew comprised of many ingredients.

Disruption 11: Mobile commerce. In Japan, cell phone users are increasingly using built-in near-field communications technology to swipe their phones near special point-of-sale terminals to buy things.

Disruption 12: Mobile security. Of course, security is needed for mobile commerce and many other next-generation applications. Not only will future phones be secure, but they'll be used in other contexts to ensure security.

Disruption 13: Augmented reality. Imagine looking at something in the real world -- say a building -- through your mobile device, then putting a virtual overlay over it. Sounds like a game, but it potentially has some very real-world applications.

As we see the future will offer a lot, and more. So how can we choose what is best for us

among all the providers and services.

Mobile cell phones

A mobile phone (also called mobile, cellular phone, cell phone or handphone) is an electronic device used for full duplex two-way radio telecommunications over a cellular network of base stations known as cell sites. Mobile phones differ from cordless telephones, which only offer telephone service within limited range through a single base station attached to a fixed land line, for example within a home or an office.

A mobile phone allows its user to make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed line phones across the world. It does this by connecting to a cellular network owned by a mobile network operator. A key feature of the cellular network is that it enables seamless telephone calls even when the user is moving around wide areas via a process known as handoff or handover.

In addition to being a telephone, modern mobile phones also support many additional services, and accessories, such as SMS (or text) messages, email, Internet access, gaming, Bluetooth short range wireless communication, infrared, and camera, MMS messaging, MP3 player, radio and GPS. Low-end mobile phones are often referred to as feature phones, whereas high-end mobile phones that offer more advanced computing ability are referred to as smartphones.

The first handheld cellular phone was demonstrated by Martin Cooper of Motorola in 1973, using a handset weighing 2 kg (4.4 lb.). In the year 1990, 12.4 million people worldwide had cellular subscriptions. By the end of 2009, only 20 years later, the number of mobile cellular subscriptions worldwide reached approximately 4.6 billion, 370 times the 1990 number, penetrating the developing economies and reaching the bottom of the economic pyramid.

The Apple iPhone vs. The Blackberry vs. The Droid

The iPhone is a line of Internet and multimedia-enabled smartphones designed and marketed by Apple Inc. The first iPhone was introduced on January 9, 2007. An iPhone functions as a camera phone, including text messaging and visual voicemail, a portable media player, and an Internet client, with e-mail, web browsing, and Wi-Fi connectivity. The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. Third-party applications are available from the App Store, which launched in mid-2008 and now has well over 200,000 "apps" approved by Apple. These apps have diverse functionalities, including games, reference, GPS navigation, social networking, and advertising for television shows, films, and celebrities.

There are four generations of iPhone models, and they were accompanied by four major releases of iOS (formerly iPhone OS). The original iPhone established design precedents like screen size and button placement that have persisted through all models. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a compass, faster processor, and higher resolution camera, including video. The iPhone 4 has two cameras for Face Time video calling and a higher-resolution display. It was released on June 24, 2010. The Wall Street Journal stated on October 6, 2010 that a CDMA version of the iPhone 4 would be released 1st quarter 2011 allowing compatibility with the Verizon Wireless network.

Blackberry

BlackBerry is a line of mobile e-mail and smartphone devices developed and designed by Canadian company Research in Motion (RIM) since 1996. BlackBerry functions as a personal digital assistant with address book, calendar and to-do list capabilities. It also functions as a portable media player with support for music and video playback and camera picture and video capabilities. BlackBerry is primarily known for its ability to send and receive (push) Internet e-mail wherever mobile network service coverage is present, or through Wi-Fi connectivity. BlackBerry is mainly a messaging phone with the largest array of messaging features in a smartphone today. This includes auto-text, auto-correct, text prediction, support for many languages, keyboard shortcuts, text emoticons, push email, push Facebook and MySpace notifications, push EBay notifications, push instant messaging with BlackBerry Messenger, Google Messenger, ICQ, Windows Live Messenger and Yahoo Messenger; threaded text messaging and a customizable indicator light near the top right of all Blackberry devices. All notifications and conversations from applications are shown in a unified messaging application which third party applications can access also. Many of these applications would have to be running in the background of other phones to be used. BlackBerry's push gives BlackBerry devices their renowned battery life. All data on the phone is compressed through BlackBerry Internet Service (BIS). BlackBerry has about two thirds less data transfer than any other smartphone, while supplying the same information.

The Droid

The Motorola Droid X is an Android-based smartphone by Motorola, distributed exclusively by Verizon Wireless in the US.

Features of the phone include Wi-Fi capability, HDMI output, and 8-megapixel camera with 720p video recording, 1.0 GHz TI OMAP3630-1000 processor, a 4.3" FWVGA LCD display, and 3G wireless hot-spot capability. The Droid X has a dedicated camera button instead of a shutter button on the touch screen. The Droid X comes with 8 GB of internal flash memory and 16GB on a MicroSD card included (upgradeable to 32GB) total memory expandable up to 40 GB. Unlike the Motorola Droid, the Droid X does not have a physical keyboard, but instead features Swype and a multi-touch QWERTY keyboard. Like most Android phones it has GPS, text to speech and live traffic. It does not have a trackball, but an equivalent workaround can be tried via keyboard.

Laptop vs. Netbook vs. Tablet PC

A laptop is a personal computer designed for mobile use that is small and light enough for it rest on the user's lap. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a track pad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. A laptop battery in new condition typically stores enough energy to run the laptop for three to five hours, depending on the computer usage, configuration and power management settings.

Netbooks are a category of small, lightweight, and inexpensive laptop computers suited for general computing and accessing Web-based applications typically with long battery life. At their inception in late 2007 - as smaller notebooks optimized for low weight and low cost netbooks omitted certain features (e.g., the optical drive), featured smaller screens and keyboards, and offered reduced specification and computing power. Over the course of their evolution, netbooks have ranged in size from below 5" screen diagonal to 12". A typical weight is 1 kg (2-3 pounds). Often significantly less expensive than other laptops, by mid-2009, some wireless data carriers began to offer netbooks to users "free of charge", with an extended service contract purchase.

Tablet Personal Computer

A tablet personal computer (tablet PC) is a portable personal computer equipped with a touchscreen as a primary input device designed to be operated and owned by an individual. The term was made popular as a concept presented by Microsoft in 2001but tablet PCs now refer to any tablet-sized personal computer regardless of the operating system.

Unlike laptops, tablet personal computers may not be equipped with a keyboard, in which case they use a virtual onscreen substitute. All tablet personal computers have a wireless adapter for Internet and local network connection. Software applications for tablet PCs include office suites, web browsers, games and a variety of applications. However, since portable computer hardware components are low powered, demanding PC applications may not provide an ideal experience to the user. The Tablet PC market was invigorated by Apple through the introduction of the iPad device in 2010. While the iPad may not adhere to the personal computer definition because of its critized restrictions on software installation, its uncompromising attention to the touch interface is considered a milestone to the Tablet PC development history.
