VIAVI introduces mmWave support in CellAdvisor base station analyzer

November 16, 2017 // By Jean-Pierre Joosting
VIAVI Solutions has announced that the CellAdvisor JD700B Series of base station analyzers have been augmented to analyze spectrum and interference of 5G signals in the 28 GHz frequency band.

CellAdvisor has been adopted by several Tier-1 mobile service providers as a standard test platform and is familiar to their cell site technicians, riggers and contractors.

To accommodate the higher speeds envisioned in 5G, the industry is expanding to higher frequency bands than those used in preceding generations. Several network equipment manufacturers and service providers – including Ericsson, Huawei, Samsung, AT&T, Softbank, U.S. Cellular and Verizon – are conducting trials of 5G radios in the 28 GHz band.

To support customer demand for testing in 28 GHz, VIAVI has introduced a frequency downconverter for the CellAdvisor JD700B Series, enabling spectrum and interference analysis for the additional band using a familiar and proven platform. VIAVI collaborated with ThinkRF, a pioneer in software-defined spectrum analysis that monitor, detect and analyze complex waveforms in today's rapidly evolving wireless landscape.

"Our customers are conducting 5G trials while serving hundreds of millions of subscribers on existing networks. They would prefer to minimize cost and complexity by using test and measurement systems their technicians and contractors already know," said Kevin Oliver, Vice President and General Manager, Converged Instruments and Virtual Test, VIAVI Solutions.

CellAdvisor base station analyzers are trusted by mobile service providers, cell site technicians, riggers and contractors for their RFoCPRI and NB-IoT testing needs. The platform offers dual-port capability, cable and antenna analysis, spectrum analysis, interference analysis, signal analysis, demodulation and RF, optical power meters and optional fiber inspection in a rugged, portable, cloud-enabled instrument. Applications include: demodulation of all wireless technologies up to LTE; fiber inspection; interference analysis and PIM detection over CPRI; fronthaul and remote radio head verification over CPRI; and 5G spectrum and interference analysis.
