Operating Frequency Band and RSRP for LTE

Choosing which frequency band to operate a LTE network is one of the most critical decision. Operator has to make when it comes to capacity planning. The frequency propagation and penetration characteristics will determine the number of sites that need to be built in order to cover the designated area chosen by the Operator. This … Read more
