Fourth Generation Mobile
Author: Joseph J. Trail
The fourth-generation telephony seems to be getting closer. This is confirmed by Telefónica, already doing the first test in Spain which will allow “total connectivity” for high-generation multimedia services and a minimum yield of 100 megabits per second download speed to 50 megabits per second upload speed.
The first experiments consisted of VoIP calls and video call using a small network installed by Ericsson.
The company explained that this technology will download a file in just 54 seconds with previous generations of mobile as GPRS took more than 34 hours. Telefonica said it is the first global operator that allows voice calls end LTE by integrating this technology with existing service networks.
However, the company qualified that the first commercial version of this technology, you need the 2.6 GHz band and 10 or 12% more base stations than existing networks will have to wait until at least 2011.
Until it is possible to commercialize this technology, Telefónica wants to further exploit the possibilities of its current third-generation network
For this reason, the company announced that this summer will begin offering nominal speeds of 21 Mb on download speeds and 5 Mb in sending information through HSPA + technology, third generation pre-LTE.
The operator explained that they arrive as new features and terminals are able to reach the 84 Megabits per second until the arrival of that fourth generation.
As the use of Wimax equipment, Telefónica said possibly observe their applications in other countries sometimes “point.” The telecommunications sector announced that, although until 2010 there will be no adequate equipment on the market for 2.6 GHz band, and availability of WiMax equipment, which can offer mobile broadband at 2.6 GHz
In Japan, NTT DoCoMo already has a testing time doing this type of mobile Internet and got the 100 megabits from a vehicle at 200 km / h.
