4G LTE Single Radio Access Network (SRAN)

Course Overview

As LTE operators formulate a commercial and technical strategy aimed to maximize revenue and minimize costs as well as meet subscriber expectations, all synergies need to be explored with regard to deploying multi-technology radio access networks. Single radio access network (SRAN) involves deploying LTE/HSPA/GSM functionality in a single base station unit, and hence reduces the operator’s total cost of ownership (TCO). This course examines the SRAN market, products, architectural models, backhaul options and core network connectivity.
