Verizon Wireless Crawls To 4G

Kristin Abraham — Fri, 06 Apr 2007 16:01:00 +0000

Verizon is planning to head down the 4G road but which path they’ll take is still uncertain. Ultra Mobile Broadband (UMB) is the logical path but not the only option. In fact, at the CTIA Wireless 2007 Conference, Kyle Malady, Vice President of Network Technology Development at Verizon Wireless, stressed that the company feels they have a host of opportunities and they’re taking a careful look at all of them. Currently, Verizon is trying three 4G technologies to see which best suits its needs and which one could offer them a quick to market advantage. But the company stresses that it will not be making any hasty decisions and in the meantime will continue with CDMA2000 EV-DO Rev A.

NTT DoCoMo Achieves World’s First 5Gbps Packet Transmission In 4G Field Experiment

Eliza Villarino — Thu, 15 Feb 2007 16:27:00 +0000

NTT DoCoMo announced that its field experiment of fourth-generation radio access in Yokosuka, Kanagawa Prefecture on December 25, 2006 saw the attainment of a maximum packet transmission rate of about 5Gbps in the downlink using 100MHz frequency bandwidth to a 10km/h mobile station. The development followed the company’s decision to increase the number of MIMO transmitting and receiving antennas from 6 in a December 14, 2005 test, where the maximum speed reached 2.5Gbps, to 12. The ratio of data transmission rate to channel bandwidth from the previous to the latest testing also increased two-fold from 25bps/Hz to 50bps/Hz (5Gbps/100MHz). DoCoMo plans to report the experiment’s details before the 3GSM World Congress 2007 in Barcelona, Spain.

Why Sprint Says WiMax Is 4G

Eliza Villarino — Tue, 31 Oct 2006 12:15:00 +0000

Sprint CTO Barry West regards WiMax the 4G technology because not only is it faster, it is also cheaper. According to West, WiMax causes a 10-fold improvement in the price-per-bit as it uses a wider channel. The current CDMA networks run on a 1.25-MHz channel and can deliver a maximum of 4 bits per hertz, or around 5Mbit/s at the base station. WiMax, on the other hand, makes use of a 10-MHz channel, thus it can generate a total of 40Mbit/s.

3G is barely deployed and now there is talk about 4G. Sprint is aiming to use WiMax as thier 4G technology of choice, expecting to put $3 Billion into the technology in the next 2 years. Faster speeds are one factor for the choice of WiMax but chipset costs and availability have also influenced the decision.

Samsung Breaks 4G Barrier

Eliza Villarino — Mon, 18 Sep 2006 09:30:00 +0000

Samsung unveiled its 4G WiBro (Wireless Broadband) technology at a forum it sponsored in Jeju Island, Korea. The company claims that WiMax’s cousin, which is based on the IEEE 802.16.e-2005 standard, generates a nomadic speed of 1 Gbps or 50 times speedier than 3G. This means that transferring 100 MP3 files (300Mb) will only take 2.4 seconds and an 800Mb movie, 5.6 seconds.
