Channel selection in home 802.11 standard networks

WiFi is one of the most popular wireless standard today. However its popularity is killing itself. The number of local networks dramatically arises and as results one can achieve much worse parameters then expected if taking into accounts the devices and different 802.11 standards specifications. One of the main reasons is interference. The authors test two real networks and make an optimisation of channel choice using tools which are available for ordinary user. The results shows total lack of any channel coordination in private networks and necessity of future works to improve the situation.
