For a wireless mesh network with randomly placed devices, the paper analyzes the impact of beamforming on the statistics of the signal attenuation, interference, and SIR between devices. This paper shows that simple random direction beamforming performs equally well as omni-directional transmission if no MAC layer is present. Optimized beamforming between transmitter-receiver pairs yields a much better SIR than omni-directional antennas. If devices are able to eliminate the strongest interferers, either using a MAC protocol or null steering, both beamforming approaches perform much better than omni-directional transmission, i.e., they allow for a given SIR threshold more concurrent transmissions in the network.
