History


Radiophones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held mobile radio devices have been available since 1973.
In 1960, the world’s first partly automatic car phone system, Mobile System A (MTA), was launched in Sweden. MTA phones were composed of vacuum tubes and relays, and had a weight of 40 kg. In 1962, a more modern version called Mobile System B (MTB) was launched, which was a push-button telephone, and which used transistors in order to enhance the telephone’s calling capacity and improve its operational reliability. In 1971 the MTD version was launched, opening for several different brands of equipment and gaining commercial success.[5][6]
Martin Cooper, a Motorola researcher and executive is considered to be the inventor of the first practical mobile phone for hand-held use in a non-vehicle setting, after a long race against Bell Labs for the first portable mobile phone. Using a modern, if somewhat heavy portable handset, Cooper made the first call on a hand-held mobile phone on April 3, 1973 to his rival, Dr. Joel S. Engel of Bell Labs.[7]
The first commercially automated cellular network (the 1G generation) was launched in Japan by NTT in 1979, initially in the metropolitan area of Tokyo. Within five years, the NTT network had been expanded to cover the whole population of Japan and became the first nation-wide 1G network. In 1981, this was followed by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norwayand Sweden.[8]. NMT was the first mobile phone network featuring international roaming. The first 1G network launched in the USA was Chicago based Ameritech in 1983 using the Motorola DynaTAC mobile phone. Several countries then followed in the early 1980s including the UK, Mexico and Canada. .
The first "modern" network technology on digital 2G (second generation) cellular technology was launched by Radiolinja (now part of Elisa Group) in 1991 in Finland on the GSM standard which also marked the introduction of competition in mobile telecoms when Radiolinja challenged incumbent Telecom Finland (now part ofTeliaSonera) who ran a 1G NMT network.
In 2001 the first commercial launch of 3G (Third Generation) was again in Japan by NTT DoCoMo on the WCDMA standard.[9]
One of the newest 3G technologies to be implemented is High-Speed Downlink Packet Access (HSDPA). It is an enhanced 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, also coined 3.5G, 3G+ or turbo 3G, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity.

TOP 10!

Enjoy our roundup of some of the best mobile phone stories you may have missed this week:

1. webOS 2.0 on Video.

Version 2.0 of Palm’s webOS has been treated to a leaked preview video and although it’s nowhere near as exciting as the HTC video, it’s still worth a watch! Running on an emulator, it provides a great insight into what will be coming out of Palm now that HP are on the scene.

2. Android Continues Market Share Increase.

During Q2, Android’s lead over RIM and Apple in the market share stakes increased again, up from 12% to 17%, while RIM fell from 41% to 39% and perhaps surprisingly given the recent release of the iPhone 4, Apple dropped from 25% to 23%.

3. Angry Birds Feast on BlackBerries.

The massively popular iPhone game has come to RIM’s BlackBerry OS, ensuring that no matter what phone you own, you get to fight some green pigs. It’s available for download from BlackBerry App World.

4. China Sees iPad Release.

The Apple iPad has been released in several new markets this week, with pre-orders also being taken at the amazing Beijing Apple Store in China. The other countries getting the iPad are Argentina, Chile, Columbia, Ecuador and Peru. According to sources at the event in China, the first customer in-line queued for sixty hours and purchased two.

5. Windows Phone 7 Shows up in a Bing Ad.

This awful Bing advert featuring Rachel Zoe of The Rachel Zone Project – ’stop searching and start retching’ – is bearable if you turn the volume down, but is notable for using Windows Phone 7, on that Samsung prototype again, to advertise the Microsoft search engine. How long will it be before WinPho7 gets an advert all of its own?

6. Another New Nokia Appointment.

We’ve seen a new CEO and a new UX expert join Nokia recently, and now the company has announced that they have a new CTO too. Ex VP of Software at Sun Microsystems, Rich Green, will be driving the compnay’s technical strategies forward and is quoted as saying they ‘don’t need to wait for Symbian^4′ to do so, but should ‘advance Symbian^3 at an aggressive rate’ now.

7. Skyfire Reaches Download Milestone.

Alternative mobile web browser Skyfire, now available on Android and with a little luck, soon to be seen on the iPhone too, has reached one million downloads on the Google platform alone. Skyfire is well-known for its video capabilities and a similar compression technique used by Opera on Opera Mini.

8. LG Going 4G in the USA.

While not especially relevant in Europe at this stage, LG could be bringing a 4G mobile phone to the US’s Sprint network, and it could be running Windows Phone 7. Sprint is a CDMA network, which may not be seeing the new Microsoft OS until 2011.

9. It Looks Like a Phone…

But it’s not. You could use your Sony Ericsson Walkman phone, your iPhone or whatever other device you like to listen to your music, but why bother when you can use an MP3 player that looks like an old brick-style phone? Complete with huge casing, massive buttons, a radio and built-in speakers, this is the retro way to listen!
