Explanation

802.11g Wi-Fi operates on the 2.4 GHz frequency band. A 2.4 GHz cordless phone (A) operates on the same frequency and will directly compete for the same radio spectrum, causing interference and degraded network performance. A 900 MHz cordless phone (B) operates on a different frequency band and will not interfere. Bluetooth devices (C, D) also operate at 2.4 GHz but use frequency hopping spread spectrum, which causes much less interference than a 2.4 GHz phone. The 2.4 GHz cordless phone is the most significant and direct source of interference.
