The fourth generation (4G) Long Term Evolution-Advanced (LTE-A) standard is for next-generation local- and wide-area mobile platforms supporting high peak data rates; handover between wireless bearer technologies; Internet Protocol (IP) core and radio transport networks for voice, video and data services; and support for call control and signaling. With peak data rates of 100 Mbps in WANs and 1 Gbps in fixed or low-mobility situations, and all-IP core, radio access and transport networks, 4G will be mostly implemented as LTE-A.
