Experimental Study on Co-existence of 802.1 lb with Alien Devices

Several kinds of wireless communication systems, such- as IEEE 802.11, BT, HomeRF, and cordless telephones, have been developed to run in the 2.4 GHz ISM band. In many cases, these technologies are complementary rather than competing, and are likely to co-exist in the same environment. This paper presents experimental results of the co-existence tests among these different systems working in the 2.4 GHz ISM band. The main goal of this work is to determine how the performance of 802.11b is degraded in the existence of such other devices in the neighborhood. This should be the first step towards a better co-existence solution for IEEE 802.11b WAN in this band.
