Answer 1

Along with the people to the life request's enhancement, the traditional mobile communication already could not satisfy the daily life the demand, the high mobility and the high volume of goods handled already became in the future the wireless communication market important demand. IEEE 802.20 are precisely to meet this need, but designs specially the motion wide band tetherless access technology, and has the performance to be good, the efficiency is high, the cost is low and deployment nimble and so on characteristics, solves mobilized and the transmission speed mutually contradictory question effectively, enables the user to be possible to enjoy the pleasure which in the high speed migration the wireless broadband access brings. IEEE 802.20 are one kind of newest motion wide band tetherless access technical standards, it is between mobilized and the peak value speed perfect union. In order to let everybody clear understanding 802.20 this kind of migration wide band tetherless access technical standard, this article historical which and the technical performance target produces to it carries on introduced briefly that has analyzed 802.20 standard agreements and the system structure, narrated with emphasis this standard's core technologies, discussed this standard with other wireless broadband access technology and the mobile communication technology (for example WiMAX, 3G) between complementarity and competitiveness, obtained itself to the future wireless broadband access view and to the future communication forecast.
