Factors impacting RSSI

As we have seen in the previous sections, different propagation effects and equipment characteristics will impact the performance of a wireless LAN, hence the size and shape of the coverage area. We can group these parameters in three categories:

Please note is that the performance of a wireless network will not only depend on the quality of the access point but also on the quality of the wireless clients. A given access point may have a good performance when used with high quality wireless clients. The exact same access point in the same environment may exhibit a lower performance when different clients are used. The higher the sensitivity and the antenna gain, the better. For instance most USB client sticks have a poor antenna (because the antenna must fit on the USB stick) when compared to laptops with embedded antenna, mounted in the LCD screen.
