IEEE802.20标准直逼3G在新兴的无线技术中,鉴于Wi-Fi与802.16(城域无线宽带系统)的覆盖范围均很有限,为了既保证Wi-Fi的连接速度,还要使其覆盖范围与移动电话相当;802.20(移动宽带无线接入,MBWA)技术被推到了前台。看来,3G既得利益者与新兴技术推动者之间的控制权之争已难以避
IEEE802.20 standard almost equal to 3G In the emerging wireless technology, in view of Wi-Fi and 802.16 (metro wireless broadband system) coverage is very limited, in order to not only ensure the Wi-Fi connection speed, but also to make its coverage Equivalent to mobile phones; 802.20 (Mobile Broadband Wireless Access, MBWA) technology was pushed to the foreground. It appears that the controversy over control between vested interests in 3G and emerging technology promoters has been elusive
