In April 2008, Motorola demonstrated the first EV-DO to LTE hand-off – handing over a streaming video from LTE to a commercial EV-DO network and back to LTE. [ 34 ] In April 2008, LG Electronics and Nortel demonstrated LTE data rates of 50 Mbit/s while travelling at 110 km/h (68 mph).
The pre-4G 3GPP Long Term Evolution (LTE) technology is often branded "4G – LTE", but the first LTE release does not fully comply with the IMT-Advanced requirements. LTE has a theoretical net bit rate capacity of up to 100 Mbit/s in the downlink and 50 Mbit/s in the uplink if a 20 MHz channel is used — and more if multiple-input multiple ...
For technical details on LTE and a list of its designated operating frequencies, bands, and roaming possibilities, see LTE frequency bands. Bands 33 to 53 are assigned to TDD-LTE. Note: This list of network deployments does not imply any widespread deployment or national coverage.
Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming in ITU Regions 1, 3 and partially Region 2 (e.g. Costa Rica, Venezuela, Brazil and some Caribbean countries or territories. Networks on LTE band 20 (LTE-FDD) are suitable for roaming in ITU Region 1 only. Networks on LTE band 5 (LTE-FDD) are suitable for roaming in ITU Regions 2 and 3.
From the network's perspective, this is the same as the mobile moving out of the coverage area. Occasionally, calls are dropped upon handoff between cells within the same provider's network. This may be due to an imbalance of traffic between the two cell sites' areas of coverage. If the new cell site is at capacity, it cannot accept the ...
LTE's Enhanced Multimedia Broadcast Multicast Services (E-MBMS) provides transport features for sending the same content information to all the users in a cell or to a given set of users (subscribers) in a cell using a subset of the available radio resources with the remaining available to support transmissions towards a particular user (so-called unicast services).
LTE-U would allow cellphone carriers to boost coverage in their cellular networks, by using the unlicensed 5 GHz band already populated by Wi-Fi devices. LTE-U is intended to let cell networks boost data speeds over short distances, without requiring the user to use a separate Wi-Fi network as they normally would.
System Architecture Evolution (SAE) is the core network architecture of mobile communications protocol group 3GPP's LTE wireless communication standard.. SAE is the evolution of the GPRS Core Network, but with a simplified architecture; an all-IP Network (AIPN); support for higher throughput and lower latency radio access networks (RANs); and support for, and mobility between, multiple ...
