Microsoft’s Airband effort appears to be gaining steam through the company’s steady announcements of additional carrier and vendor participants. The effort is noteworthy in that it is a nonprofit attempt by Microsoft to, in part, leverage TV White Spaces spectrum to build out fixed wireless internet services in rural areas of the United States, thus crossing the so-called digital divide.

Microsoft announced the program in July of 2017, promising to invest “in partnerships with telecommunications companies with the goal of bringing broadband connectivity to 2 million people in rural America by 2022. We and our partners will have at least 12 projects up and running in 12 states in the next 12 months.”

The company said it would engage with carriers and vendors through public-private partnerships, and each one of those deals would be unique. In some cases Microsoft is investing directly into the telecommunications companies, but in others is only acting as a facilitator.
