Since the eighties, the mobile phone has changed from an expensive item used by businessmen to a truly popular personal communications device that's used by much of the general population. in actual fact, nowadays, mobile phones outnumber land line telephones in several countries.
Mobile telephones were born whena number of users of mobile radio, known as the mobileers, made mobile phone technology more popular. Mobile phones were originally installed in vehicles permanently, although more sophisticated versions of them, which were called transportables, could also be carried, which meant they could be used as a mobile or as moveable two-way radio. during the early forties, Motorola developed a two-way radio in a backpack, the walkie talkie, & this was widely regarded as one of the first mobile phones.
The very earliest mobile phones were called first generation phones, also called 1-g. The 1-g era lasted from the late 1970s through to the 1980s. these devices were the very first real mobile phones, although they were then named cellular mobile radiophones, and were based on analogue signals. the analogue signal was the main difference between these first generation mobile phones and their second generation cousins, which emerged a while later.
The very first second generation mobile telephones were commercially launched in 1991 in finland. While 2g networks were completely digital, the previous 1-g networks were analog. one of the benefits that 2g networks had over the 1g predecessors was that telephone conversations were digitally encrypted. This was significant because third parties could to eaves drop on calls on analog networks. as well as this, 2g systems were much more efficient, which allowed far more mobile telephones to be used. Finally, 2g introduced data services for mobile, which include sms text messages.
After 2g mobile phones were launched, the previous mobile phone systems were named 1g. whilst radio signalling on 1g networks are analog, and on 2g networks they're digital, both networks use digital signals to connect the radio towers and the rest of the telephone system.
The first pre commercial 3g mobile phone network was launched in japan in may 2001. 3-g was later commercially released in Japan on 1 october 2001.
3g is the third generation of mobile phone standards & technology, which is the successor to 2g technology. the birth of 3g technologies enabled network operators such as orange to give their users a larger range of more advanced services. This includes wireless internet, as well as high tech video calls.
Despite the success of 3-g, there's also been some complaints about it. These include criticism over the expense of 3-g phones, a lack of network coverage because it's still a relatively new service & the high power usage of 3g phones.
We hope our article has let you know more about the history of the mobile phone. As you've probably realised, the mobile phone's come an awful long way and will probably continue to progress further still.
4-g technology will certainly give mobile phones a new lease of life, potentially offering the live streaming of tv and radio shows & much more. For the mobile phone, it seems that the sky's the limit.
