Does your WLAN planning cover the two primary elements of a wireless network?


Comprehensive wireless network performance assessment and optimization has to cover in detail the two primary elements of a wireless network: its propagation environment and its network devices. The propagation environment is defined by the RF transparency and reflectivity of building materials and objects. The network main device parameters are transmission power, receiver sensitivity and antenna pattern. Using these parameters, the propagation environment is considered separately from the viewpoint of each receiver to determine the properties of the signal path between itself and all transmitters that could affect it. This allows exact determination of the signal to noise + interference ratio for each received signal – this determines the data rate for each transmitter in RF range.
