Over the past 25 years, cellular networks have gone through several evolutions, from 1G to 2G, 3G and then LTE. Now we are on the forefront of LTE-A, LTE-A Pro and soon 5G. Arguably, the largest disruption is to come from IoT, the Internet of Things.

Many new technologies are being developed to provide low-cost connectivity for IoT devices. There are Low Power Wide Area (LPWA) technologies like NB-IoT and LTE Cat-M1/M2, and new 3GPP standards like Power Saving Mode (PSM), extended DRX cycles (eDRX) and Extended Access Barring (EAB), to name just a few.

For MNOs and MVNOs to support the explosive growth of IoT devices, several areas are key:

  • Infrastructure cost. Virtualization, using open standards like OPNFV and the newly formed Open Source MANO (OSM) Community under ETSI is a requirement for controlling cost.
  • Managing congestion. IoT devices must not impact the QoE of human subscribers. Both control-plane and data-plane cannot be allowed to run Over The Top (OTT), without operator management.
  • New service opportunities. Downward pressure on subscription pricing will continue. Operators must find new opportunities for revenue, beyond simple charging for device connectivity.

Here at Definition Networks, we provide solutions to MNOs and MVNOs, addressing the above key areas. Our company vision:

To develop products and solutions that help fulfill the IoT vision of billions of connected devices over cellular networks in a cost effective manner, and to generate new revenue opportunities for Mobile Network Operators and Mobile Virtual Network Operators.

Operators are considering how to deploy the 3GPP SCEF (Service Capability Exposure Function). For background material on SCEF, please read through our  tutorial SCEF Primer. For introductory details on how SCEF is used to support NB-IoT, please see our NIDD via SCEF for NB-IoT page. Then, for insights about the problems that need to be solved, please visit our Our Solution for MNOs and MVNOs.
