Remote radio head test solution adds 3 GHz support

October 31, 2012 // By Jean-Pierre Joosting
Signalion has announced that its RHT100 compact remote radio head (RRH) test solution supports the frequency range of 3.3 to 3.9 GHz beside the existing range of 200 MHz to 2.7 GHz. Consequently, the 3GPP LTE TDD bands 42 and 43 are supported. All LTE bands specified by 3GPP are covered by the RHT100 with this extension.

Mobile network infrastructure is changing. Traditionally, long RF feeder cables were used for the connection between the base station and the antenna. The new approach uses optical cable connections between the base station and the RRH which is normally mounted on the top of the tower close the antenna. The idea behind this is to avoid the attenuation of the long RF feeder cables and to reduce the number of cables from the ground to the top of the mast.

The company’s RHT100 covers the radio and the optical interfaces of an RRH and serves as a compact test solution for these RRHs. It can be used in R&D as well as in production lines to substantially reduce the testing time. Due to the integration of all necessary equipment the tester can easily be controlled over an API. This simplifies integration into existing test environments.
