Wireless communication technology capable of covering a wide range overwhelmingly faster than ever

As next-generation high-speed wireless communication technology, NTT DoCoMo is promoting "downlink speed of 100 Mbps or more"Super 3G"And WILLCOM achieved the transmission speed of 20 Mbps"Next Generation PHS System"Intel plans to support"WiMAXAlthough various approaches such as "The prototype of the high-speed communication technology using the terrestrial analog broadcasting band are completed in America, it is said that it is completed.

By the way WiMAX seems to be able to cover a wide range exceeding 10 km, apparently this technology seems to cover an area far beyond that.

Details are as below.
New superfast wireless broadband device prototype submitted to FCC

According to this article, Philips has developed this communication technology this time, using a frequency band (2 MHz to 698 MHz) of analog television to realize a communication speed of 80 Mbps downstream, shielding walls of analog television radio waves By utilizing the strength against things, it is said that it can cover an area that significantly exceeds WiFi and WiMAX.

In addition, in the United States in February 2009 we are ahead of the end of terrestrial analog broadcasting, and we are saying that we want to use the bandwidth of the surplus frequency for the current communication technology by shifting to digital television. By the way, it is a bad influence on radio waves of digital TV, but it seems to be designed to guarantee not to cause interference problem.

In Japan, it is terrestrial analog broadcasting scheduled to stop on July 24, 2011, will similar technology be introduced?
