Course Details
With the current increase in machine to machine communications or IoT,
the 3GPP technologies have been enhanced to support this new type of
data transfer. This course focuses on the 4G or LTE network and the
various modifications which have been introduced in Release 12, 13 and
14. These include new network infrastructure, modified air interfaces
(NB-IoT / LTE-M) not to mention support for NIDD or Non IP Data
Delivery. Various network optimizations will also be addressed along
with new procedures dealing with network monitoring. Finally, mobility
will be reviewed before culminating with a brief look at how Cellular
IoT interworks with legacy 2G and 3G networks.
