ABSTRACT
A wireless network is a system capable of connecting terminals to the data network without the need to use communication wires. Wireless networks present new challenges given that data travels through the air as radio waves. Other challenges result from the unique possibilities of wireless networks, which allow freedom to move, achieved through the removal of wires. The complexity of wireless networks increases by embedding characteristics and metrics, which are added to configuration parameters. The chapter introduces a new parameter used for the optimization of wireless networks: free space loss. In a communication system, free space loss is considered the attenuation suffered by the electromagnetic waves on their way from the transmitter to the receiver. The chapter presents the basic constraints that are necessary for the solutions found to be feasible. It examines the new functions for transmissions in wireless networks and the presented constraints.
