Well if mobile communications is important to you, this announcement from DoCoMo is sure to please. The figures here are amazing, an average of over 100Mbps, and they were able to achieve 300Mbps from a moving car. Unfortunately Americans won't see this for quite a while as cellphone companies in the states are behind the curve, but it is good news for cellphone users around the world.
"The company said that the test achieved a maximum downstream data rate of 300Mbps with an average rate of 135Mbps in a car running at the speed of 30 kilometers per hour in areas 800m to 1km away from the 4G wireless base stations."
"[4G's average speed] is as at least as fast as any fiberoptic connection you can get at the moment, and means you can stream HDTV to your phone"
