Abstract

An IEEE 802.11b/g/n wireless local area network (WLAN) experiences significant radio frequency interference (RFI) from microwave ovens, cordless phones, Bluetooth devices, and other WLANs operating in the 2.4 GHz band. In particular, microwave ovens emit interference that can either prevent an access point from transmitting or cause a dramatic increase in bit errors at the receiver. This paper investigates the disruption in delay sensitive streaming applications under microwave oven RFI. The proposed contributions of this paper include
  1. a statistical-physical model of oven-generated RFI in WLAN channels that is dependent on distance and frequency,
  2. an increase in the information rate bound of up to 5 bits/s/Hz due to the more realistic statistical-physical model of oven-generated RFI, and
  3. a proposed transmission strategy to achieve the higher information rate bound.
