Are there any issues with radio interference with other devices and Wi-Fi?
Radio frequency (RF) interference involves the presence of unwanted radio signals that disrupt normal system operations. Because of the way 802.11 works, an interfering RF signal of certain characteristics can appear as a bogus 802.11 station transmitting a packet. This causes legitimate 802.11 devices to wait for indefinite periods of time until the interfering signal goes away.
For 2.4 GHz wireless LANs, there are several sources of interfering signals, including microwave ovens, certain wireless phones, and other wireless LANs. The most damaging of these are 2.4 GHz wireless phones that can be found in homes and local businesses. If one of these phones is in use within the same room as an 802.11b/g wireless LAN, then expect poor Wi-Fi performance.
