Title: "Survey on solving the interference in 2.4GHz ISM band"

by

Mr. Jiayue LI


Abstract:

In the past few decades, as a swift and violent increasing demands on 
telecommunication services, it brings massive technical evolutions to 
2.4GHz ISM band, such as the utilization of ZigBee devices in the 
Intelligent Home Control, or the development of the 802.11a standard to 
the 802.11n, etc. 2.4GHz ISM band, a popular and problematical spectrum 
domain, has been fully exploited in recent decade of years. Due to the ISM 
band could be accessed by the public without the license, more and more 
wireless devices and services are operating concurrently, which brings 
potential signal interference at the same time. According to this survey, 
we are going to first introduce the basic usage situation of the 2.4GHz 
ISM band in recent years, and then focusing on two kinds of interference 
issues in this band, the heterogeneous and homogeneous interference. By 
analyzing how these two kinds of interference are generated in wireless 
network, we will bring several solutions which concern about these issues. 
In the end, this survey would conclude several drawbacks from the current 
solutions and provides some possible future research topic based on the 
interference issue.
