Tests NB-IoT features on Base Stations  

The C-SGN Emulator, as part of the NetTest suite, emulates the optimized EPC network required for CIoT testing by combining the MME, SGW, and PGW functions to create an end-to-end lab environment for the enhanced Machine Type Communication (eMTC) and Narrow Band Internet of Things (NB-IoT) implementations to be tested. To reduce complexity in the setup of a test environment, it also supports emulation of the SMS Service Center Function (SMS-SC) and the Service Capability Exposure Function (SCEF).

The Polaris Networks C-SGN (CIoT Serving Gateway Node) Emulator extends NetTest Suite capability to test the 3GPP Release 13 CIoT (Cellular Internet of Things) features.

Useful for chip manufacturers of devices and base stations, and network equipment manufacturers, this solution is equally useful for stakeholders in research and test establishments, protocol stack vendors, base station vendors, as well as IoT device vendors for testing their IoT optimized implementations.
