EXFO Test Solutions Used to Verify if China Mobile's Network Can Support Operation of 5 Million NB-IoT Devices

China Mobile Communications (CMCC) with the support of EXFO's test solution has successfully concluded a performance verification test for the core networks from 4 major vendors. The test was done to confirm whether these NFV-based networks can individually support 5 million Narrowband IoT (NB-IoT) devices.

Since the NB-IoT specification got ratified in June 2016, communication service providers have been preparing to roll out this service in their network. They are upgrading their networks by deploying additional features to handle the tremendous capacity that the millions of Internet of Things (IoT) devices will need. Handling the IoT traffic is fundamentally different from the traditional mobile broadband or VoLTE traffic. Validating the equipment and the network is crucial to ensure that they deliver the quality of experience expected by end users while avoiding costly post-deployment faults.

EXFO's comprehensive test solution was preferred for three main reasons:

  • Powerful performance: capacity to simulate millions of IoT devices on one single server, keeping network configuration simple
  • Unique flexibility: ability to adapt to rapidly evolving specifications and specific requirements
  • Extensive test coverage: covers the network from end to end, including focus on individual nodes

EXFO delivers comprehensive solutions for the validation of 2G/3G/4G/5G networks and equipment for all kinds of services. These test solutions are also future-proofed to verify unique services for upcoming 5G networks.
