NB-IoT UE Protocol-Stack 
Release-13/14

CCww has developed a low-footprint NB-IoT Access and Non-access Stratum, tested on the host and ready for porting to target systems. Underpinning the AS/NAS is a Layer-1 Control sub-layer, with a generic set of drivers for rapid customisation to suit a client's base-band (either a DSP/PHY or pure hardware logic). CCww offers an Object Licence for the above, based on CCww providing integration/test services; or a Source Licence, whereby CCww and the Client may share the integration and test activities. The outline specification is shown below:
