Anritsu Boosts Capability of its 4G Testing Equipment

July 08, 2016

Remote radio heads play an important part in the infrastructure of wireless networks. These units connect to operator control panels and may extend signals from the central panel into rural areas or in enclosed spaces such as tunnels. These are not dummy devices; they can convert and transmit multiple radio signals as needed, and they can give telecommunication companies an easy way to reach areas of the globe that may have once seemed out of reach.

The usefulness of these devices only persists when they work properly, so firms such as Anritsu Company develop field analyzers to give telecom engineers an easy way to interface with radio heads from the ground level. In June, Anritsu announced that its E-series Site Master, Spectrum Master, and Cell Master field analyzers have gained support for testing connections that use the common public radio interface (CPRI) standard developed by global telecoms such as Alcatel-Lucent, Huawei, and Nokia. With that capability, engineers can now test for interference of radio heads that work within their 4G networks.

The new field analyzers begin their own usefulness by reaching speeds that literally sweep away the competition. According to Anritsu, the devices’ sweep speed is 10 times faster than competing units. This means that they can quickly identify interfering radio signals and show the origin of interference on a spectrogram encased in the analyzer itself. Technicians can zoom into the affecting areas to more accurately pinpoint the affected radio heads and the signals that may cause their poor operation.

Reaching that point does not have to be a manual process. Anritsu has also included an auto-detect function to determine how the radio head uses the CPRI standard to speak to its base station. This way, techs can begin troubleshooting faster than they could if they had to determine the connection method step-by-step.

This boost to the various E-series units adds to the capability of those handhelds and also marks another jump in Anritsu’s entire portfolio of remote unit and base station testing equipment. For telecoms that rely this type of equipment to make sure their networks run at peak performance, the addition of CPRI test functions can make the work day move smoothly and help companies control a large part of their overall operating costs by quickening tests while ensuring network performance.
