Most of the time we don’t know or even care how we connect. Its just “that” we connect and when we don’t or can’t we get really cranky. At work its usually simple: either you can or can’t depending upon whether Wi-Fi access is enabled for your tablet or laptop. (Smartphones usually take care of themselves with mobile wireless access that operates independently from your business network) Watch for an explosion of Wi-Fi availability, especially in dense urban areas and even the implementation of MANs, metropolitan area networks.
