4G Technology – A Peek Into History



4G Technology and its predecessors 3G, 2G and 1G are all from the same family of cellular communication standards, which are verified by the ITU. The ITU i.e. International Telecommunications Union is established by the United Nation, which administers all the telecommunications matters all over the world. The earlier technologies like 1G and 2G did not able to cope up with the current technologies 3G and the latest 4G. The earlier telephone systems, which were the original ones, are now called 1G. In the year 1991, 2G started to replace the old 1G and was first launched in Finland. The network system of 2G was way more than the 1G, had better radio communication and 2G networks were digital.

3G
After 2G, came the more efficient technology 3G, it established its roots in late 2000, while ITU agreed to the 3G standards in 1999. The Third Generation technology now can easily be found all over the world on nearly all standard radio technologies such as CDMA and the GSM. The first cellular network provider that set up the 3G grid in the year 2003, is Verizon. 3G technology provides up to 2 mpbs data transfer rate at fixed spots (when user is stationary) and minimum 384 kbps when the user is moving. Today almost all the well-known carriers of US provide 3G service and now there are lots of gadgets available in the market with 3G capability.



4G technology

4G technology, the Fourth Generation Technology, is the very latest and ultra fast technology and it is getting more attention day by day even though this technology is still at its initial stages. 4G technology aims to provide fastest speed to all the users, to the users of mobile or smartphones it intends to provide data transfer rate up to 100 mbps while for its stationary users, it aims to the highest speed of 1 Gbps.
WiMAX and LTE
These are two 4G cellular broadband networks. The WiMAX provides speed up to 128mbps of downloading and for uploading it provides 56mbps, whereas LTE showed in an early implementation speed up to 100mbps downloading and 50 mbps uploading. ITU considers the LTE (Long-Term Evolution) as a standard technology because LTE aims to exceed the specifications of ITU. While WiMAX on the other hand is an IEEE standard, also ITU doesn’t considered WiMAX a true 4G technology because it is not up to the specifications that ITU put forth.


There is a difference between Apple iphone 5 and ipad 2 they might not distribute the same tech characteristics inside, the practical and efficient control will choose the destiny of both.
But when you talk about the outer material body fashion and shape and model of Apples lately approaching two new valuable products revolve in 2011, one simply has to glance as back as last year or therefore to obtain logic for how much they could be predictable to imitate both of them superficially: even though they will not get finished same look-alikes, they will perhaps class as fraternal ones.

Throughout the early days of 2010 the organization of Apple launched the unique Apple ipad pill which restricted then- exclusive polished metal silver siding and an all about flat glance – very much praise balance to any iphone had been, for case. But then a sevral month shortly Apple announced the Iphone 4 which unluckily, not accidentally, presents precisely the similar metal siding in addition to the same plane design. 
Despite of its privacy when it arrives to unexpected result and functions much like the apple iphone ipad2 and 5G, and its try at forever remain the earth guessing, apple recommends steadiness. It is the cause why the launch time for every new age group of every result line (ipad through the springtime, iphone throughout the summer time, Ipod from Apple in fall) likely to be foreseen. And this is the reason why its polished metal glances, once worn for few of its creations, deal to find out its path in to all of its creations, from the accommodation of their Imac individual computer to the decoration on its safari and itunes appliances. 

To place it in another way, if your are actually interested about accurately what the iphone 5G could maybe appear as this year goes on, just don’t take yours eye away from ipad2 when it facade first. There is a possibility that may not be able to attribute a black glass support even as the iphone 4 contains a black glass support. But if you talk about the wide caress in term of surface shape, except of route Apple is varying
Its outline, the roadmap headed for the Apple iphone 5 shape styling will surely work with the ipad 2 body shape.



Whilst hurry was the primary, all of the foremost cell phone transporters in the United States which are revolving around the 4G set of connections on and a few pleasing to the eyes Cell Phones which are coming alongside in haul.
Well I thought that it might be an ideal time to cover up the 4G Cell Phones which are at present obtainable or will be on the rampage in the next few months in view of the fact that the mainstream of the cell phones is unconfined by every cell phone supplier which indeed is the most absolutely not 4G. One mania you will observe is that every cell phone on the list is empowered by the Operating System of Google Android.
