Three years ago, the U.S. government decided to offer airwave licenses for small areas so factories, ports, and power plants could set up their own wireless networks without relying on commercial carriers.
This week, the Obama-era experiment is likely to end before the licenses had even been auctioned.
The Federal Communications Commission is expected to vote Tuesday to abandon its novel small-area plan and instead offer larger licenses covering a minimum of a county. The vote came after carriers such as AT&T Inc. and Verizon Communications Inc., who can afford to wire larger areas, persuaded the regulators to reconsider.
Supporters of the Obama initiative say the change will squeeze out smaller players who could find innovative uses for very local networks covering an area as small as a single building.
"Imagine being at the dawn of the Uber age and doubling down on taxicab medallions," Commissioner Jessica Rosenworcel, a Democrat, said in an email. "That's what this agency is doing."
The FCC's Republican majority says change helps make the airwaves available for next-generation, ultrafast 5G networks that are a focus of commercial development and U.S. technology policy under President Trump.
"The commission needs to evolve with the ever-changing marketplace," FCC Commissioner Michael O'Rielly, a member of the agency's Republican majority who drew up the revised plan for the airwaves, said in an Oct. 2 speech. The need for 5G networks to use the airwaves has become apparent since the FCC's previous decision, O'Rielly said.
The new plan "does not favor any one use or favor any class of user, which was a flaw in the last administration's rules," O'Rielly said in an email. "Everyone will be able to bid in an auction that will ensure that the spectrum goes to its best use."
O'Rielly noted support for the change to county-size licenses from industries including cable providers, which increasingly are offering wireless connections to their subscribers.
The change follows a request last year from the largest U.S. mobile providers, including a petition by the CTIA trade group with members including AT&T and Verizon, and a separate request by T-Mobile U.S. Inc.
The big carriers argued that small license areas were cumbersome to administer and the thousands of users operating wireless systems near boundaries threatened to interfere with other users of airwaves. Supporters of the small-area licenses said the interference risk was small, since many systems would operate at low power and indoors. Under the FCC's 2015 order, access would be sold in each of 74,000 census tracts. That number compares with about 3,200 U.S. counties, according to the FCC.
General Electric Co., in a filing with the FCC, said opening up the airwaves to small-area licenses could lead to a world of intelligent industrial operations, in fields including power generation and distribution, oil and gas, manufacturing, health care, rail, and aviation. Automated inspection and sensor technologies — including aerial drones, terrestrial crawlers, and robots — could use the systems to provide real-time video and monitoring, GE said.
"We're disappointed in the expected decision," a GE representative said in an email. "It's a missed opportunity for U.S. manufacturers, but we are committed to finding ways to provide our customers with the technology and support they need regardless."
The planned revision is another instance of Republican FCC Chairman Ajit Pai changing rules set under earlier Democratic control. Large telephone providers have benefited, with Pai's FCC arguing that regulations being shed have damped investment by forcing unnecessary expenditures, or posed needless barriers to deploying fast networks using new technology.
In the dispute over the 3.5 GHz airwaves, a variety of industries have argued for the smaller, census-tract license areas. For instance, GE said it wouldn't make sense to buy licenses covering territory that extends far beyond a site, and that it can't count on major wireless carriers offering access to airwaves. Buying licenses covering counties would cost "well beyond what GE's industrial and critical-infrastructure customers are willing to spend," the manufacturer said in a December 2017 filing.
O'Rielly has long cited problems with assigning use in small chunks. Under the plan adopted by the FCC in 2015, each census tract could be home to as many as seven overlapping licenses.
