Mobile Test Platform Targets LTE and LTE-A Base Stations
Aeroflex has launched the TM500 Multi-UE LTE-A Test Mobile, which supports carrier aggregation across multiple mobile terminals or user equipment (UE). Carrier aggregation, a key component of LTE-A, allows multiple carriers comprised of either contiguous or non-contiguous spectrum to be added together, allowing wider channel bandwidths -- and higher data rates -- to be achieved.The
LTE-A has provision for up to five component carriers (CC) of up to 20MHz bandwidth to be combined, with the aim of raising the peak data rate to 1 Gbps and beyond. 3GPP Release 10 specifies 11 TDD bands, along with a range of scenarios for aggregating specific pairs of these bands in both contiguous and non-contiguous combinations. This technique combines the capacity of different frequency bands while maximising the benefits of the superior propagation capability in the lower frequency band.
