Not so long ago, carriers prematurely handing off traffic to another carrier risked being branded as a “hot potato” router. See a 2013 blog entry on the subject: http://telefrieden.blogspot.com/2012/03/hot-potato-routing-and-real-or-imagined.html.
It should come as no surprise that incumbent licensed carriers would prefer consumers not have an unlicensed alternative, particularly in light of the billions paid for spectrum. Whether provided free, below cost, or on profit generating terms, municipal Wi-Fi is reviled as socialism. Many legislators have bought this logic, even though they don’t seem to fret over taxpayer subsidized stadiums, golf courses, cemeteries, libraries, sewers and water authorities. With righteous indignation, opponents of municipal Wi-Fi networks claim the socialists ignore the rule of law. Never mind the law was championed, (make that written) by stakeholders keen on removing, or reducing any unmetered option. They would love a prohibition on home Wi-Fi routers, but somewhere a line can be drawn where federal authority preempts “states’ rights” and offers consumers a much welcomed option to increase the value of a broadband subscription.
