, high capacity EV-DO Rev. B. CDG also provided a roadmap for CDMA2000 as an answer to the first question. While the second is a bigger and much complex task that is still out there to be addressed and resolved. And on top of it, the absence of 3GPP2 from the IMT-Advanced (4G) project is also making things difficult for the EV-DO industry. References 1.

IEEE 802.20 Mobile-Fi 6.1 Introduction The IEEE 802.20 working group was formed on December 11, 2002 to draft a set of specifications in support of Mobile Broadband Wireless Access (MBWA), nick named Mobile-Fi. For the first few years the working group (WG) did not make any sufficient progress. In 2005 the WG activities were revived to counter the threat fro
