LTE-A test set achieves bi-directional Cat 6 capability

23rd February 2014

Aeroflex says its 7100 Digital Radio Test Set provides LTE-A carrier aggregation testing at full Cat 6 data rates of 300Mbps downlink and 50Mbps uplink simultaneously for LTE-A in FDD mode, and now also supports carrier aggregation in TDD mode. The Cat 6 capability is available via an upgrade to the standard 7100 software and the use of a RF combiner, allowing users to maximise the potential of their existing test equipment investment.

The LTE-A capability of the test set facilitates testing to 3GPP Release 10 specifications on two non-contiguous component carriers, with both FDD and TDD modes supported, and with 2x2 downlink MIMO or SISO for each component carrier. All Release 10 RF band combinations are supported, including the downlink-only Band 29.

Symmetrical bandwidths of 5+5 MHz, 10+10 MHz and 20+20 MHz are supported, along with asymmetrical bandwidth combinations that include 5MHz, 10MHz, 15MHz, and 20MHz.

Test capability—validated against the industry benchmark, the Aeroflex TM500 test mobile—includes 300Mbps DL and 50Mbps UL bi-directional data rates to Cat 6; full protocol stack; detailed logging; data connection and throughput performance test; and end-to-end throughput using IP connections. UDP, TCP IPv4/IPv6 are supported with multiple PDN connections, both with or without RoHC (robust header compression). Automated regression test is supported via API.
