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
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
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)
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.

DOCOMO is always a pioneer in cellphone technology. I still remember how they created a cellphone which has a security card that can lock the phone if the card is certain distance away from the phone. That somehow prevents people from stealing cellphones and sell it in the black market.
By the way, I do agree with you that Japan has a lot of nice cellphones, and I've always wished I can buy one from Japan and use it in other countries. However, Japanese seems to like to own their closed network. Sigh.
Regarding 3G or 4G, what I concern is about the cost of the service. Although there are 3G services in many Asia countries, such as my hometown Hong Kong, but not many people are using it because it can cost as much as US$1.3 per minute. It's rather hard to get people to adopt to this network and gain network externality. Also, it can be much harder to setup the 3G or 4G network in the United States because US is really large and population is not as dense as in many Asia countries. It's not that easy to have access points or transmission centers at every (hot)spot. But I do hope this technology can be the standard for most cellphones and telecommunication services.
Hey Ting, nice Blog.
In contrast to what Peony said about Hong Kong, in Korea, 3g is widely used; it is known as the "DMB" (digital multimedia broadcasting) technology. Usually people in Korea now "video-chat" to each other, rather than just "talk" on their phones. Also, they all watch live TV from their phones. It's quite interesting what phones can do now.
Also KT (Korea Telecom) is testing out 4g technology as well. They announced that Korea has the infrastructure set up already, and is now seeking firms to carry it out (LG-Nortel seems to be a big player).
I think Korea and Japan are both interested in being technology leaders. Maybe you should compare them or relate them.
Oh my, after reading Brian's comment, I feel like moving to Japan or Korea, but I wonder is 3G or video-chat much more expensive? Or they have unlimited plans?
Also, I concern about the security issues. I mean when video-chat and television broadcasting on cellphones become so popular and easy, will it be a much easier way for hackers to massively spread virus around through video clips or 3G network?
This is really cool, but as you have pointed out, and my peers have made apparent this type of technology is not readily found in the US. It may not be found in many places. 4G may be an integration of several platforms, but only for countries like Japan that have it. It seems that in the age of globalization, there is an asynchronis adoption and use of technologies. I wonder how that will play out?
