NTT DOCOMO (Japan) Reaches World’s First Achievement in 5 Gbps Package Transmission in 4G Field Experiment

Hi! Eveyone, welcome to my blog!

Today is my first blog entry. Let me introduce myself first.

My name is Ting. I major in Accounting and Information System at USC. I am interested in all Japanese stuff, such as technology, stars, dramas and music. (my favorite idol group: KAT-TUN) I like collecting stamps and playing the piano.

On my blog, I will post something about Japan and new technology that I am interested in. And I hope these will be exciting to you.

NTT DOCOMO is a Japanese leading mobile communication company. Since Japanese cell phones cannot be used outside Japan, it is not strange that not many of you know it. At the very beginning, its various types of cell phone designs are eye-catching to me from its commercials. Its cell phone contains 3G features, which are common in Asia, but not in US, where we are still living in 2G to 2.5G. NTT DOCOMO is famous by its 3G FOMA (Freedom of Mobile multimedia Access) service, based on W-CDMA, which has now moved the mobile communication environment to the next level in Japan. FOMA not only provides voice transmission quality, it also supports diverse multimedia content.

NTT DOCOMO recently announced that it achieved a maximum packet transmission rate of approximately 5Gbps in the downlink using 100MHz frequency bandwidth to a mobile station moving at 10km/h. This field experiment of fourth-generation (4G) radio access took place in Yokosuka, Kanagawa Prefecture on December 25, 2006.

5Gbps is very fast transmission rate. If you use this transmission rate to download something, your download speed will reach to 625mb/s.

What is 4G?

“The Wireless World Research Forum (WWRF) defines 4G as a network that operates on Internet technology, combines it with other applications and technologies such as Wi-Fi and WiMAX, and runs at speeds ranging from 100 Mbps (in cell-phone networks) to 1 Gbps (in local Wi-Fi networks). 4G is not just one defined technology or standard, but rather a collection of technologies and protocols to enable the highest throughput, lowest cost wireless network possible.” (Wikipedia: http://en.wikipedia.org/wiki/4G)

This great milestone that NTT DOCOMO reaches is a revolution in data transmission in 4G technology field. Since it plans to launch 4G around 2010 in Japan, this successful achievement really pushes NTT DOCOMO a big step forward. I am looking forward to seeing this new technology used in future’s cell phone communication.
