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
- a statistical-physical model of oven-generated RFI in WLAN
channels that is dependent on distance and frequency,
- 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
- a proposed transmission strategy to achieve the higher
information rate bound.
