I have several colleagues in the retail industry talking about free Wi-Fi being &quot;the next big thing&quot; and several major chains are only just jumping on board. I&#x27;m incredibly confused by it - we&#x27;ve reached a point where everyone has a mobile device with 4G at better speeds than the 1MB DSL service shared across 20 patrons.<p>I would have sworn from a technology point of view, that buying a bunch of APs to offer free Internet in your café would be a dying trend.
