Protocol tester expands to cover MBMS

MBMS test scenario for the R and S CRTU-W protocol tester allows manufacturers of mobile radio user equipment and chipsets to check the functioning of their products.

Multimedia Broadcast Multicast Service (MBMS) is an expansion of the UMTS mobile radio standard that makes it possible to transfer multimedia data such as mobile TV or MMS to many users simultaneously.

This significantly reduces the network load compared with other methods such as streaming.

Rohde and Schwarz has now developed an MBMS test scenario for the R and S CRTU-W protocol tester that allows manufacturers of mobile radio user equipment and chipsets to check the functioning of their products.

The company is among the first to provide such a solution for the development of MBMS-capable user equipment.

With an expansion of the R and S CRTU-WT02 option, the MBMS test scenario can be implemented with up to four transmission channels.

For this purpose, in addition to the R and S CRTU-W, only an internal data generator or external media server is necessary.

The transmission channels support datarates of up to 128 or 256Kbit/s, and the datarate can be defined as desired for each channel.

As the solution includes extensive logging capabilities, functional errors of user equipment can be easily analysed.

The expanded R and S CRTU-WT02 option is now available from Rohde and Schwarz and can also be installed on existing CRTU-W protocol testers by means of software update at a later date.
