By the way, the three camps of KDDI, DoCoMo, and Softbank Mobile are "next generation high speed communication standard"Mobile WiMAXAlthough promoting KDDI campaign, Intel who advocated "mobile WiMAX" is joining, and it is already focusing on technological development and demonstration experiment ahead of other companies, mainly on Intel It was said that KDDI was appointed as one of the only Japanese mobile phone companies to be a company from 15 secretaries who operated the International Industry Association "WiMAX Forum".

Mobile WiMAX can be used even when moving at 120 km / h, the area covered by one base station is 1 to 3 km, the maximum transmission speed is 21 Mbps. Also, among the four camps, only WILLCOM promotes the "next generation PHS" that has developed the current PHS technology, but also hereA transmission speed of 20 Mbps or more is realizedThat's right.
