New services such as SMS and low-rate data. Primary technologies include IS-95 CDMA and GSM. 3G ITU’s IMT-2000 required 144 kbps mobile, 384 kbps pedestrian, 2 Mbps indoors Primary technologies include CDMA2000 1X/EVDO, WiMAX, and UMTS-HSPA. 4G ITU’s IMT-Advanced requirements include ability to operate in up to 40 MHz radio channels and with very high spectral efficiency. No technology meets requirements today. IEEE m and LTE Advanced designed to meet requirements.

© 3GPP LTE India, New Delhi, May 10, 2013 Ways of working New work initiated by member companies via Work Items outlining scope and time plan. Work Items prioritised if all estimated work cannot be done by the scheduled release deadline. All 3GPP member companies contributes on equal terms on any work item 3GPP seeks consensus on all technical matters (but has mechanisms if consensus cannot be reached) Release deadline respected, unfinished work deferred to a later release
