Abstract
The demand for broadband wireless communication in home and office has been increasing exponentially; thus, the need for reliable and effective communication is very crucial. Both theoretical and experimental investigations have clearly shown that electromagnetic radiation from external sources such as microwave oven (MWO) has detrimental impact on the wireless medium and the media content. Therefore, this drastically degrade the signal strength in wireless link and consequently affects the overall throughput due to noise and interference. This experimental study is primarily aimed at critically analyzing and evaluating the impact of electromagnetic radiation on spectrum utilization under different experimental scenarios. The experimental results clearly show that electromagnetic noise radiation from microwave oven can seriously affect the performance of other devices operating in 2.4GHz frequency band, especially, delay sensitive applications and services.
Highlights
Wireless communication is increasingly becoming popular and widely used in recent years due its flexibility, scalability and low cost of deployment
Cellular phones and microwave ovens are the most common household appliances operating in the frequency band which can electromagnetically radiates noise, and it interferes with other devices
An experimental investigation of effects microwave oven noise has been presented in order to evaluate the electromagnetic radiation impact on WiFi spectrum band
Summary
Wireless communication is increasingly becoming popular and widely used in recent years due its flexibility, scalability and low cost of deployment. It can be potentially applicable in health, public, and commercial sectors. The electromagnetic radiation from other equipment operating in the same frequency band could cause interference and subsequently degrades the performance of the wireless network. Cellular phones and microwave ovens are the most common household appliances operating in the frequency band which can electromagnetically radiates noise, and it interferes with other devices. The electromagnetic radio frequency (RF) power radiated from microwave oven can cause loss data or connectivity in wireless networks [4], [5]. The impact of some devices on WiFi networks has been studied in [6]
