Data rates that users can sustain in both uplink and downlink can be increased because of multiple input multiple output (MIMO) technology. MIMO is therefore a new technology for 5G networks and beyond. Because of the large number of existing antennas, users are empowered by large data rates inside massive MIMO (mMIMO). A modified form of mMIMO known as cell-free mMIMO distributes the current antennas through the cell. In addition, a central controller that can integrate signals from many access points APs using a cooperation mechanism takes the position of the base station. By applying the maximal ratio combining (MRC), the cell-Free networks were analyzed and simulated. The implemented APs cooperated at four different levels. This manuscript is concerned with relay implementation inside cell-Free networks. The required analysis is carried out as well as simulation which is carried out with Matlab program. It can be observed that the proposed system performance is very good when the MRC is used.
