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.
ITU Targets 20 Gbps for 5G Specification
The International Telecommunications Union today released a draft report for what might eventually become the 5G specification. IMT-2020 is the working name for the 5G standard and the ITU has laid out a basic framework it wants to see technology companies meet.
AT&T: Our 5G Network Will Be 100 Times Quicker than LTE
AT&T today revealed its plans to test and eventually deploy 5G wireless technology, which it says will offer performance 10 to 100 times faster than today's LTE. AT&T is working with Ericsson and Intel to test 5G in its labs during the second quarter of the year, with field tests to follow over the summer months.
Qualcomm Develops 5G Test Platform
Qualcomm has created what it calls a prototype 5G system and trial platform. The 5G New Radio (NR) prototype is able to function across a wide range of spectrum bands, primarily below 6 GHz, and can achieve multi-gigabit per second data rates and low latency.
AT&T Kicks Off VoLTE Roaming in Japan
AT&T today said customers can access VoLTE services when traveling to Japan. Specifically, the carrier has struck a VoLTE roaming agreement with NTT DoCoMo, Japan's largest carrier.
Qualcomm's Snapdragon X50 5G Modem to Connect First 5G Networks and Devices
Qualcomm today said various network operators plan to use its Snapdragon X50 5G modem in trials this year, while a number of device makers have selected the X50 for mobile gear due next year. According to Qualcomm, the carriers committed to the X50 include AT&T, British Telecom, China Mobile, Deutsche Telekom, KDDI, NTT DoCoMo, Orange, Singtel, SK Telecom, Sprint, Telstra, Verizon, and others.
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..
