Polytron, a Taiwan based company has created a phone that is fully transparent and only the circuit board, memory card and camera unit is visible. It is a touchscreen phone that has a fully functional SIM tray, SD card slot, microphone and camera. Polytron has also revealed that they plan to release a fully functional device in limited quantities by the end of the year 2013. All of these devices have the potential to be incorporated appropriately into lessons, opening exciting new approaches to learning. When these technologies are misused by students they can be very disruptive to teaching and learning and in some cases cause harm. All plans come as a Standard license, and can be upgraded to an Enhanced license at any time.
Researchers at St&T Labs came up with the idea of using low powered towers to create a cellular broadcasting network.
Cell towers recieve and transmit signals than include information such as dialed phone numbers. Advances in computer technology allowed cell phones to dramatically shrink in size during the 1990s and into the 2000s. The first mobile phone invented is rooted in the history and technology of the hand held radio. The first mobile phone call was made by a truck driver as an experiment in the summer of 1946 from a phone weighing close to 80 pounds. Limited mobile phone service was available, providing for about three calls to take place at one time in any service area. The first hand held mobile phone call was made by Martin Cooper, who led the team that developed the first hand held phones. Mobile telecomunication service capabilities improved in 1982 when the Federal Communications Commission (FCC) approved the establishment of a mobile telephone system and allocated a limited number of analog frequencies to be used by the network. In the early to mid eighties, mobile phones were commonly called car phones as they were permanently mounted in automobiles.
A significant breakthrough in mobile phone technology came when the mobile system became cellular.

Cellular technology was invented by Joel Engel and Richard Frenkiel, two researchers for AT&T Labs, in 1983.
It's really interesting how mobile phones evolved from two way radios to mobile phones, to car phones, to bag phones, and finally to the cell phones we use today. From data by CCID Consulting, the sales volume in China's mobile phone market is 150 million units in 2007, which is 24.1% more than that of 2006. In 2007, over 60% of users changed their mobiles with over 90 million mobiles sold for this purpose. CCID says that the competition of products on the market will be rather fierce while the China mobile market is developing on a large scale.

It's so funny to think about how different it was in the 1940's, when you had to wait for a mobile line to open up. Now, if a cell phone user experiences a cell phone service interruption, it's a huge deal.
These days, most people use the term cell phone and mobile phone interchangeably, but they aren't really the same thing. One that I especially remember is the original Wall Street, when Michael Douglas's character is talking on his phone. If black- market mobiles from smuggling, unregistered brands and other illegal products are counted, the number exceeded 200 million in 2007. The reasons could be attributed to faster function upgrades, higher performance- price ratio, shorter product life cycle, and customized service by the network operators. The homogeneity, price wars, and sinking channels will direct consumer behavior, and manufacturers will turn from seizing market share to chasing profit.

I think the difference is that a mobile phone is just any phone you can take with you, but a cellular phone operates on a cellular network. Anyway, I had no idea the first mobile phone was invented in the 1940's. The number of new subscriber reached a new record in recent years with over 86 million new subscribers in 2007 and over 7 million per month. The certificate of mobile authority and the launch of the China 3G mobile market will stimulate market competition and create concentrated market share in already-advantaged brands and less market share in small brands.

It was state of the art for that time, but extremely bulky compared to the laptop I'm typing on right now. It will also create competitive cooperation among manufacturers, distributors and network operators.
Mobile rigs did not use the telephone network and users could not dial out to standard telephone numbers. They were huge compared to the cell phones we use now, but it sounds like they were very light compared to the first mobile phone.
