Trouble is, Access Providers does not own any spectrum and by assuming they can hog the spectrum by installing at a site is illegal, as anyone else may install at the same site and attempt to use the same frequencies. Regulation of the cheapskate class licensed band will be inevitable if this sort of behaviour eventuates, and is a significant longer term risk to investors of any service provider who does not own spectrum. Unwired however holds licenses over enormous amounts of spectrum, allowing commercially viable and huge capacity networks without fear of interference.
