As the TD-LTE ecosystem ramps up, test and measurement companies are hustling to get in on the action as evidenced by the latest announcement from Spirent Communications, which is offering TD-LTE support on its CS8 mobile device tester.
The company said the CS8 is now able to perform data throughput, voice quality, location based services and mobility testing for chipsets and mobile devices that support TD-LTE. The tester can emulate MIMO-enabled cells for both the TDD and FDD flavors of LTE networks simultaneously within a single instrument.
Spirent also integrated its DatumLab solution--a lab-based evolution of the Datum measurement tool--with the CS8 for data performance measurement of LTE devices using FDD and TDD.
The company said its CS8 also integrates Spirent's Nomad HD measurement system to enable voice quality performance analysis of HD Voice services in TD-LTE networks. The system is certified under the Perceptual Objective Listening Quality Assessment (POLQA), also known as ITU-T Rec. P.863. Further, the CS8 enables support for TD-LTE A-GPS over-the-air testing to provide validation of GPS performance in mobile devices.
In early July, Anritsu announced that the Global Certification Forum (GCF) had confirmed that the company's ME7834 mobile device test platform offers the highest number of validated protocol conformance test cases for TD-LTE, including interworking with TD-SCDMA and GSM.
In June, the Global mobile Suppliers Association (GSA) announced that nearly 950 LTE-enabled devices have been announced for use on LTE networks, including 200 that can operate using the TD-LTE mode. The most popular TD-LTE bands in terms of number of devices are 38 (2.6 GHz) and 40 (2.3 GHz), said the group.
