The node mobility, dynamic topology and the fundamentally limited capacity of the wireless medium, together with wireless transmission effects such as attenuation, multipath propagation and interference, combine to create significant challenges for routing protocols operating.
The signal's noise-like properties protect against interference, relieve multipath propagation, and allow sharing of bandwidth with other users.
MIMO-OFDM exploits multipath propagation, an inherent feature of all wireless communications environments, delivering greater throughput, range, and reliability.
