There's a microwave based ISP in SF called Monkeybrains. From their about us page: "Monkeybrains is primarily a WISP (Wireless Internet Service Provider). What this means is Monkeybrains uses microwave technology to create a wireless network covering much of San Francisco. We deliver internet service to individual locations by placing an antenna on the roof. This antenna picks up an encrypted wireless signal from one of our network access points which can be found on over 1000 buildings city-wide. From the roof, we run a Cat5 Ethernet wire either to the unit, telecom closet, or the property's Ethernet patch panel. We are happy to comply with any building wiring guidelines or work with the building's riser company if required." https://www.monkeybrains.net/how-it-works https://www.monkeybrains.net/how-it-works http://www.popularmechanics.com/technology/infrastructure/a19741/can-an-indie-isp-beat-comcast/ http://www.popularmechanics.com/technology/infrastructure/a1... They are pretty responsive in terms of customer service. *Don't work for Monkeybrains but my company uses their service.
