Abstract :
With the increasing popularity of 802.11 wireless technology, such equipment has recently been used to set up long distance links for wireless mesh networks. To be able to increase the range of 802.11 equipment directional antennas are required. In this paper, we investigate the effects of interference between collocated directional antennas, which would be the case for a typical multi-hop node. Results of measurements taken in an experiment show that antenna orientation and placement and channel separation at such a multi-hop node have a significant impact on the achievable throughput.
