Wi-Fi, But Not on Steroids: Performance Analysis of a Wi-Fi-Like Network Operating in TVWS Under Realistic Conditions

Free registration required

Executive Summary

The recent decisions by regulators in the USA and UK to open up unused portions of UHF spectrum for secondary use have been met with keen interest in using these TV White Spaces (TVWS) for providing broadband services through Wi-Fi-like connectivity. Amid the ensuing media hype about "Wi-Fi on steroids", there is a widespread perception that Wi-Fi operating in TVWS will provide much longer range, superior speeds, and more reliable connections than traditional Wi-Fi at 2.4 GHz. In this paper, the authors present a quantitative analysis of the performance of a network of Wi-Fi-like Access Points (APs) operating in TVWS in order to obtain a realistic estimate of the achievable range and downlink rate of such a secondary system.
