With the growing application for of wireless services, the capacity of 2G (2nd Generation) networks and 3G (3rd Generation) is reaching saturation point. New technologies become interest to researchers to meet with developed services, from these technologies a multi-hop relay system. This paper presents the performance analysis of amplify and forward (AF) relay network. In order to get a realistic transmission, the Signal to noise ratio (SNR) and bit rate during Uplink (UL) and Downlink (DL) transmission mode are derived in this paper. Moreover this paper discusses the impact of relay placement node to provide a maximum achievable rate at users and increase the coverage especially at cell edge regions. The numerical results shown there are enhancing in bit rate by using AF relay in comparison with direct link.
