Realistic wireless channel models consider the impact of multipath propagation. Since a transmitted signal is subject to reflections and refraction on walls, surfaces, and so forth, the receiving node will see signals differing in phase and amplitude. Using more than one antenna allows the evaluation of different multipath scenarios to avoid or reduce the effects of fading and interferences. Diversity is used to describe a strategy for choosing the best of two paths of transmitting or receiving an RF signal in order to maximize the possibility that a packet will be correctly received.
