TD-LTE receiver test system

30 September 2009 Test & Measurement

Agilent Technologies recently announced TD-LTE (Test Data-Long Term Evolution) receiver measurements as a software upgrade to its proven E6474A drive test network optimisation platform.

Agilent is locally sold and supported by Concilium Technologies and has supplied a number of the E6474A systems to wireless service providers throughout Africa. “The Agilent W1314A receiver with this software upgrade extends the capabilities to allow the service provider to quickly verify base-station RF coverage, plot accurate coverage maps and validate planning in the early development of LTE networks,” says Steve Alves, managing director of Concilium.

This new option builds on the existing FDD-LTE (Frequency Driven Duplex-Long Term Evolution) measurements in the Agilent solution to provide both FDD-LTE and TD-LTE measurements on a single measurement platform. The Agilent drive test platform already supports established, related wireless technologies, including HSPA+, UMTS, 1xEV DO and TD-SCDMA. The W1314A receiver with the software enhancement will not only measure LTE P-SCH, S-SCH RSSI and LTE Cell-ID, but provides simultaneous measurements of the older 2G and 3G networks as well.

Although LTE is the first global wireless standard, it is built on earlier technologies, allowing its enhanced platform to overlay analysis. An Agilent receiver can measure up to eight frequency bands – which eliminates the need to carry additional receivers into the field, making the platform a flexible solution.
