Viavi developed software-based NB-IoT testing that can be installed as a license on existing CellAdvisor handheld devices, which are trusted by major operators worldwide. The integration of this feature into the software further enhances CellAdvisor as a comprehensive solution for the market, offering RF-in-CPRI and BBU emulation, as well as LTE testing and automated interference detection to help maximize technician efficiency during Base Station (BSS) visits.
With NB-IoT support, CellAdvisor measures the interference and performance impact that the NB-IoT signal can have on the LTE broadband signal. It also confirms whether the signal has the necessary range and coverage to meet the required number of equipment in the assigned geographic area, taking into account requirements such as building penetration. The comprehensive analysis includes signal power levels, digital demodulation analysis, and interference analysis down to the Physical Resource Block (PRB) for the measured signal.
“While much of the mobile communications industry’s focus is on 5G, our carrier and network equipment manufacturing customers are also engaged in planning for IoT services,” said Kevin Oliver, Vice President and General Manager of Converged Equipment and Virtual Testing at Viavi Solutions. “Their research is exploring innovative new applications for mobile connectivity, and we are excited to offer relevant testing solutions that don’t require disrupting their core operations.”.
