Baby monitors and wireless TV transmitters are responsible for slowing down Wi-Fi connections in built-up areas according to an Ofcom-commissioned report. The regulator commissioned the report to evaluate the effectiveness of the unlicensed 2.4GHz band that Wi-Fi operates over.
The report smashes the myth that huge congestion on overlapping Wi-Fi networks is responsible for the poor performance of Wi-Fi in urban areas. Instead it points the finger of blame at the raft of unlicensed equipment operating on the 2.4GHz band. “There is a view that some domestic users generate excessive amounts of Wi-Fi traffic denying access to other users ” claims the report from wireless specialists Mass Consutling.
“Our research suggests that this is not the case rather the affected parties are almost certainly seeing interference from non-Wi-Fi devices such as microwave ovens Audio Video senders security cameras or baby monitors.”
