Abstract

This paper reports on the experimental analysis of hybrid back-haul links comprising WiFi operating in the 5 GHz and Ultra High Frequency Television White Space bands. Possible link permutations are highlighted. Performance results show that overall network optimisation requires a combination of frequency division and time division duplexing.

The authors would like to thank Dr. Albert A. Lysko from CSIR Meraka Institute and Dr. David Erwin from Mathematics Department at UCT. Dr. Lysko provided expert RF advice on the experimental setup, interpretation of results and multiple other useful resources, and logistical support. Dr. Erwin contributed Graph Theory insight that was helpful in deriving a generalised expression in Sect. 4. This work was funded in part by the Hasso Plattner Institute (HPI) scholarship award.
