Do radio signals/intercoms interfere with the signal?
Generally, no. The wireless LAN operates in the 2.4-2.5GHz range, which was set aside by the FCC for wireless communication purposes. However, newer technologies (such as those based on Bluetooth) will operate in this frequency range, which may create problems in the future. There is a debate currently going on between the proponents of Bluetooth and those of IEEE802.11 regarding this possible problem and its effects. Household appliances, especially microwave ovens, may create interference with the wireless communication.
