Abstract: Abstract newline newlineVoIP (Voice over Internet Protocol) converges data and voice on a single communication channel. A study was done on SIP (Session Initiation Protocol) and VPN (Virtual Private Networks) helps in virtual communication and multimedia applications like audio, video, streaming videos transmission. Factors like environmental hazards, flammable objects involved and electrical absorptions results in considerable path loss. For enhancement of voice transmission, we concentrate our research on signal attenuation due to path loss. A comprehensive review of propagation prediction models for terrestrial wireless communication systems is presented in this thesis. The classic empirical models are briefly described. newlineThe focus is placed on the application of path loss techniques towards the development of deterministic propagation models. Schemes to increase the computational efficiency and accuracy are discussed. Traditional statistical models are briefly reviewed for completeness. newlineIn conclusion this thesis, argues experimental result depicts the path loss issues with different heights of transceiver and receiver for urban terrain. Later it has been experimented with various other terrains like urban, rural and suburban with GSM frequency of 940 MHz. To generate the experimental result. MATLAB simulation tool used. A comparative study has been made to choose the best path loss model. Hata model shows the highest path loss at receiver antenna height at 10m, 15m and newline20m respectively. Further the research extends to GSM RF frequency of 940 MHz with some distance drive for various terrains like urban, rural and suburban. newlineThe preferred model for urban terrain is Hata model (Okumura) with 159 dB path loss and field value is 160 dB. In rural terrain, the preferred model is Cost 231 model with 120 dB path loss and field value is 122 dB. Finally, in suburban terrain the preferred model is Hata model (Okumura) with 169 dB path loss and field value is newline177 dB
