LTE (Long Term Evolution) and LTE Testing
	LTE is the first technology designed explicitly for Next Generation Networking (NGN) and is set to become the de-facto NGN mobile access network standard. It takes advantage of NGN capabilities to provide an always-on mobile data experience comparable to wired networks.
	LTE supports peak data rates of more than 100 Mbps on the downlink when using 20 MHz channel bandwidth, two transmit antennas at the base station and two receive antennas at the User Equipment (UE). LTE also supports peak data rates of more than 50 Mbps on the uplink when using a 20 MHz channel bandwidth; and single transmit antennas at the UE and base station. LTE generates ten to twelve times the throughput on the downlink and eight to ten times the throughput on the uplink relative to 3GPP Release 6. LTE improves spectrum efficiency as defined relative to Release 6. The uplink and downlink capabilities are two to four times the spectral efficiency of High-Speed Packet Access (HSPA). LTE has flexible duplex methods. Both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) are valid spectrum allocations and allow LTE to accommodate various channel bandwidths in the available spectrum. LTE interoperates with W-CDMA, GSM, and CDMA2000 systems. Multimode UEs will support handover to and from these other systems. Legacy technologies such as HSPA+ and Enhanced EDGE will continue to operate within the new network architecture.

TDD/FDD Access LTE standards support the use of both TDD (Time Domain Duplex) and FDD (Frequency Domain Duplex) from the same set of standards, and with the same air interface characteristics (as far as possible). Multiple Input Multiple Out (MIMO) This is an antenna technology together with signal processing that can increase capacity in a radio link. In LTE using 2x2 MIMO, the user data is separated into 2 data sets, and these are then fed to 2 separate TX antennas, and received by 2 separate RX antenna. Thus the data is sent over 2 separate RF paths. The algorithm used to split and then recombine the paths allows the system to make use of the independence of these 2 paths (not the same RF losses and interference on both) to get extra data throughput better than just sending the same data and 2 paths. This is done by separating the data sets in both space and time. The received signals are then processed to be able to remove the effects of signal interference on each, and thus creating 2 separate signal paths that occupy the same RF bandwidth at the same time. This will then give a doubling of achievable data rates and throughput. LTE also supports 4x2 MIMO, with 4 transmit antenna and 2 receive antenna, still giving 2x data rate increase, but improved diversity performance also.
