The 5Ghz band was initially less popular owing to higher equipment costs and lower propagation, but offered many more channels to choose from and potentially higher rates in not having to deal with “legacy” clients. Demands for higher bandwidths for higher throughput, improved reliability and resilience against interference, paired with rapidly reducing costs of dual-band radios have pushed many users to using the 5Ghz band as well. The 2.4Ghz band is far from ideal with limited bandwidth and high interference potential. It was initially made popular in the home by the availability of affordable, standardised 2.4Ghz equipment under the 802.11b/g/n standards. As society has moved towards ever smaller and more mobile devices, Wi-Fi has become an essential connectivity standard which we rely upon in our daily lives.
