DoCoMo Testing 4G's Speed Limit
Feb 24, 2006, 4:34 PM by (staff)
DoCoMo yesterday announced it achieved a 2.5Gbps download while traveling at 20 kmh over a 4G network test network. Although DoCoMo has not launched HSDPA or any other upgraded of 3G yet, the Japanese operator is already working on the development of 4G. As it has in the past, DoCoMo is basing the new network on modified versions of proposed standards. This test network improves the speed of proposals by the International Telecom Union (ITU) and early development by the European Union. DoCoMo's system uses 6 simultaneous transmissions with 6 antennas and an advanced encoding algorithm to achieve this high data rate, but it comes at a cost. The transmission is spread over 100 MHz of spectrum.
GOSH I WISH THEY STILL SAT ON THE BOARD OF CINGULAR!
CINGULAR has already deployed HSDPA and probably will be the first HSDPA operator in the world..
So just to re-iterate..
1> FIRST in HSDPA Commercialization, BEFORE DoCoMo
2> HSDPA with data rates on initial phones/ data...
Cant wait till it comes to the US
Just like most concept cars, never see daylight..
which operator in the world has access to that much spectrum in the first place?
in the US, you have the government agencies fighting the telecom/wireless operators fighting the tv/radio analog broadcastors all for measly amounts of airwave..
similar stuff in UK where there is constant struggle between the operators..
Hence, this 4th generation experiment from DoCoMo is just that. Probably not going to be the basis of the real 4th generation technology..
