Spirent supports LTE Carrier Aggregation testing for telecoms

T&M major Spirent Communications announced support for LTE Carrier Aggregation testing on its CS8 Mobile Device Tester.

Spirent says the CS8 assists to ensure LTE-Advanced Carrier Aggregation functionality meets the performance expectations of telecom operators in India.

Carrier Aggregation combines radio channels within and across bands to increase user data rates, reduce latency and enable LTE downlink throughput speeds of up to 150Mbps.

Offering 150Mbps speed on smartphones, Korea Telecom on Wednesday launched LTE-Advanced in Korea.

Brock Butler, mobile device testing architect, at Spirent Communications, said: “The CS8 is the only single-box network emulation solution to support the aggregation of two 10MHz carriers, each with 2×2 MIMO and independent fading – features that are critical for accurately and rapidly testing realistic deployment scenarios.”

Spirent claims that CS8’s access to the LTE protocol stack offers flexibility and configurability in carrier aggregation testing across all protocol layers—from PHY/MAC to RRC and RRM.

Additionally, CS8 is able to support all LTE frequency bands in a single box with multiple bandwidth combinations.

CS8, targeted at research and development of cellular phones, tablets, data cards and machine-to-machine cellular modules, bundles network emulation with innovative testing software and subject matter expertise into a solution that addresses the needs of design engineers.

CS8 supports Intra-band and Inter-band carrier aggregation, SISO, 2×2 MIMO, 4×2 MIMO for each carrier, cross-carrier scheduling, as well as, integrated independent fading and AWGN (added noise) for each component carrier.
