E Model Development for Land Mobile Radio System

The Land Mobile Radio System provides a radio voice broadcast system in public and private domains. Public is used by government departments like police, fire, ambulance to provide security safety services the common man. In these services, speech quality prime factor for evaluating performance of networks. There are different standards laid assessment. ITU-T recommendations G.107, named as E model, first step, which unique method calculate telephone networks once all related parameters known. Later its successive G.107.1 G.107.2 were also developed, but those focused on wideband full-band With this background, we have analyzed State Police Department. study aims develop general formula based known network parameters. model has developed quality, relates Received RF Signal Strength, Noise Ratio, Interference Deviation Frequency Drift. Our successfully implemented architectures LMRS System. Results supported statistical methods proven successful. They tested field geographical conditions found 90 95 accurate. This can be Speech Quality Design tool designing planning an analogue network.
