Cellular: A type of wireless communication that is most familiar to mobile phones users. It's called 'cellular' because the system uses many base stations to divide a service area into multiple 'cells'. Cellular calls are transferred from base station to base station as a user travels from cell to cell. - definition from the Wireless Advisor Glossary.
The basic concept of cellular phones began in 1947, when researchers looked at crude mobile (car) phones and realized that by using small cells (range of service area) with frequency reuse they could increase the traffic capacity of mobile phones substantially. However at that time, the technology to do so was nonexistent.
Anything to do with broadcasting and sending a radio or television message out over the airwaves comes under Federal Communications Commission (FCC) regulation. A cell phone is a type of two-way radio. In 1947, AT&T proposed that the FCC allocate a large number of radio-spectrum frequencies so that widespread mobile telephone service would become feasible and AT&T would have a incentive to research the new technology. We can partially blame the FCC for the gap between the initial concept of cellular service and its availability to the public. The FCC decided to limit the amount of frequencies available in 1947, the limits made only twenty-three phone conversations possible simultaneously in the same service area - not a market incentive for research.

The Changes To Mobile Phones Over The Last 30 Years
0 komentar
Although mobile phones have taken over our current society, they have been around for several decades in some form or another. Beginning in the late 1940s, the technology that would later be used in today’s cell phones was created and the idea of a mobile phone was introduced. This cell technology was first used in mobile rigs which was mainly used in taxis, police cars and other emergency vehicles and situations. Truckers also used a form of this technology to communicate with each other. Little did they know how far their idea would advance to make it accessible to the majority of the population.
The first mobile phones, referred to as First Generation or 1G, were introduced to the public market in 1983 by the Motorola Company. These first mobile phones used analog technology which was much less reliable than the digital technology we use today. The analog phones also had a great deal more static and noise interference than we are accustomed to today. The first mobile phones during this era were confined to car phones and they were permanently installed in the floorboard of automobiles. After a few years, they became mobile and consumers could take the phones with them outside of the car. However, they were the size of a large briefcase and very inconvenient. The main purpose of this First Generation technology was for voice traffic, but consumers felt insecure about people listening in on their conversations. These new mobile phones were also rather expensive, many of them costing hundreds of dollars. They were more of a status symbol during the decade rather than a means of convenience.
During the 1990s, great improvements were made in the mobile phone technology. These phones used Second Generation, or 2G technology. In 1990, the first cell phone call was made using the new digital technology that became characteristic of this era. The Second Generation cellular phone technology was faster and much quieter than its analog predecessor. As a result, it became even more popular than previous models, too. The new technology also made them capable of being smaller rather than the large briefcase-sized units from the 1980s. Smaller batteries and other technology that made the phones more energy-efficient helped contribute to their smaller sizes and their popularity. Companies also strived to make the prices more affordable than the mobile phones of the 1980s. You could buy a decent cell phone with 2G technology for approximately $200 along with an airtime service. The cell phone industry was beginning to take off.
The Third Generation technology, or 3G, is what many people currently use in their digital cellular phones today. This technology was created very soon after the excitement that the 2G technology created. This new technology is not only capable of transferring voice data (such as a phone call), but it is also able to transfer other types of data, including emails, information and instant messages. These capabilities have helped to increase the amount of sales and the popularity of these new phones. Many users prefer to use the instant messaging capabilities to “text” other users rather than call them in the form of a traditional phone call. Many cell phone companies offer free and very affordable phones for consumers who sign-up with their airtime service for a contractual period. Prices for the services range but the competition in the industry is helping to keep them more affordable than they have been in previous years.
You would think that there is little more that you could do with cellular phone technology. This is, however, not the case. There are currently plans in place to develop a Fourth Generation – 4G – technology. Goals for this new set of standards include a combination of technologies that will make information transfer and internet capabilities faster and more affordable for cellular phones. At this time, there is no one definition that can be attributed to 4G technology because researchers are still striving to make advances and build upon the technology that already exists.
The mobile phone industry continues to grow by leaps and bounds as it has in the past few decades. Even though it started a little more than 20 years ago, manufacturers have created an abundance of new technologies that keep cell phone users coming back for more. They continue to increase the number of capabilities and services to accommodate the growing needs of today’s “on the go” culture. Waiting anxiously is the only way to find out what they will think of next.
As the number and quality of WI/FI points become available and with the growth of Smart Phones that not only provide the basic functions expected in a mobile phone but provide so much more the market is changing and brand new players have entered the market including Apple with the successful Iphone and Research Machines with the equally successful Blackberry. In 2008 a new player enters the market providing an open source operating system for mobile phones that manufacturers can use and adapt, the new player is Google who make the Android operating system available and the first phone to appear is the G1 from T-Mobile, because the OS is open source the number of applications available is expected to grow and sites like The Android Library who provide a library of the latest free and commercial applications will grow. It remains to be seen if this latest entry of an Operating System in the Smartphone market will make a significant impact but many feel this could be the future for the market
2009 Update Mobile Phone Operating Systems
With the earlier entry of The Google Android Operating System for mobile phones the market hots up for the latest generation of Smartphones.
As the growth of Android increases new sites are appearing dedicated to Android just one example is The Android Library that explains much more about Android.

The mobile phone Operating system is not just about what you see on your handset but will also be used in the next generation of electronic book readers, Incar computer navigation systems and possibly even netbooks which are the fastest growing area of growth in the home computer market. Unlike other Mobile Phone Operating Systems which are tied to a single phone ( Apple, Palm and Blackberry ) or mobile phones OS which cost a a license fee, the release of android is a free software and open source license
Over the last few years the growth in the number of applications for the Iphone has grown to more than ( June 2009 50,000 applications available on the iPhone App Store ). These applications including variety, quality and usefulness and have helped to grow the Apple Iphone user base. With Google introducing the Android open source software it will be interesting to see the number of Android apps that appear on the market currently (June 2009 5000 apps on the Android App Store ) a long way behind Apple.

0 komentarMobile phones (telgam) or mobile (phone) or mobile (HP) or also referred to the electronic telecommunications devices that have the same basic capabilities with conventional phone lines fixed, but can be taken anywhere (portable, mobile) and unnecessaryconnected to the telephone network using a wired (wireless; wireless). Currently Indonesia has two systems of wireless telephone network, GSM (Global System for Mobile Telecommunications) system and CDMA (Code Division Multiple Access).The inventor of the first mobile phone system is Martin Cooper, a Motorola employee on April 3, 1973, although many so-called inventor of the mobile phone is a team from one division of Motorola (the division where Cooper worked) with the first model is the DynaTAC. The idea is triggered by Cooper is a communication tool that small and easily carried in a flexible traveling.Cooper and his team face the challenge of how to include all electronic materials into small-sized tools for the first time. But eventually a first mobile phone was successfully completed with a total weight of weighing two kilograms. To produce it, Motorola will cost the equivalent of U.S. $ 1 million. "In 1983, the portable mobile phone worth U.S. $ 4 thousand (Rp36 million), equivalent to U.S. $ 10 thousand (Rp90 million).Having succeeded in producing mobile phones, the next biggest challenge is to adapt the infrastructure to support mobile phone communication system by creating a network system that requires only 3 MHz spectrum, equivalent to five TV channels are channeled to the world.Another figure who is known to be instrumental in the world of mobile communications is Amos Joel Jr., who was born in Philadelphia, March 12, 1918, he was acclaimed as an expert in the field of switching. He got a bachelor's degree (1940) and master (1942) in electronic engineering from MIT. Shortly after the study, he began his career for 43 years (from July 1940-March 1983) at Bell Telephone Laboratories, where he received more than 70 U.S. patents in the field of telecommunications, particularly in the field of switching. Amos E Joel Jr., making a connector system (switching) from one region of the cell phone to another cell region. Switching this should work when mobile users move or move from one cell to another cell so that the conversation is not interrupted. Since the discovery of Amos Joel is the use of cell phones are becoming comfortable.sumper d.wikipedia.org
