Fiber Tower settled it's litigation with FCC

FibreTower has agreed to return all of its 24GHz licences and a portion of its 39GHz licences to the Federal Communications Commission (FCC) to settle ongoing litigation.

As part of a sprawling agreement, the spectrum holder promised to terminate two different court proceedings and pay the US treasury $27 million in exchange for reinstatement of its remaining licences, with an extended construction deadline.

AT&T, which quietly agreed to acquire FiberTower in early 2017, said that the settlement will not impact the deal. FiberTower and the US regulator were locked in litigation regarding a 2012 bankruptcy case in which a court blocked the FCC from offloading the company’s mmWave licences: a stay which remained in effect despite FiberTower subsequently emerging from bankruptcy protection.

A separate legal battle covered a failure by FiberTower to meet buildout requirements for its mmWave licences. The FCC believes the deal is in the public interest because it ends the legal action and restores regulatory certainty in the 24GHz and 39GHz bands.

The regulator also noted the agreement frees up a large portion of the 24GHz band for 5G licensing, which it said will enable “rapid deployment of 5G and next-generation wireless services nationwide”. FiberTower held a total of 689 mmWave licences, including 94 in the 24GHz band and 595 in the 39GHz band.

The company will come out of the settlement retaining approximately 478 licences in the 39GHz band.

AT&T @ 39GHz

An AT&T representative called the settlement “fair” plus is “happy with the FCC’s decision”, adding the operator still expects its acquisition to be approved, hopefully in the “near future”. The representative said mmWave spectrum is “important to our 5G strategy” and reiterated its commitment to become the first operator to introduce mobile 5G in a dozen US markets later this year.

AT&T’s work in the 39GHz band is already well underway. Shortly after announcing the FiberTower deal, AT&T conducted fixed-wireless 5G streaming tests with Nokia at 39GHz.

In December 2017, AT&T applied for permission to expand its existing fixed-wireless 28GHz 5G trials at three sites throughout the US into the 37GHz and 39GHz bands. The operator said it would use data collected from the trials to assess the viability of mmWave bands “to support 5G wireless communication systems and to validate 5G system designs operating in a non-simulated business and residential environments” in the latter bands.

More spectrum on the table for 5G.

T-Mobile US urged the Federal Communications Commission to put even more mmWave spectrum on the table for 5G, adding three more bands to the list of airwaves the commission should consider for mobile use. Through its Spectrum Frontiers proceeding, the FCC already designated the 24GHz, 28GHz, 37GHz, 39GHz and 47GHz bands for wireless service. But T-Mobile asserted the 32GHz, 42GHz and 50GHz bands should also be made available to mobile operators “as soon as possible”. Additionally, the company offered up the 26GHz band for consideration, noting use of the spectrum along with the upper 24GHz band and 28GHz band would create a contiguous 3.6GHz block of spectrum for mobile use. The operator said it conducted a technical study which showed 5G deployments in the 32GHz and 50GHz bands would be able to coexist with incumbent radio astronomy (RAS) and earth exploration satellite services (EESS). T-Mobile pointed out the FCC could protect RAS and EESS against interference in those bands with the adoption of “modest operating constraints” for new 5G services. Auction demands T-Mobile, AT&T, Verizon and industry association CTIA reiterated demands for the FCC to auction mmWave spectrum this year. T-Mobile said delaying an auction would “allow a small number of entities to dominate millimetre wave band holdings for the next few years,” thus lending them a “significant competitive advantage” as the industry moves into 5G. Verizon and AT&T both urged the FCC to forego pre-auction spectrum limits for the mmWave bands. But US Cellular, the fifth largest US operator, argued Verizon’s acquisitions of mmWave assets from XO Communications and Straight Path Communications are “evidence that the largest carriers are likely to pursue mmWave spectrum acquisition relentlessly, shutting out smaller carriers, unless they are subject to reasonable spectrum acquisition restraints both pre- and post-auction.” For now, though, it looks like operators will have to wait a bit longer for an auction. FCC chairman Ajit Pai previously stated new spectrum auctions cannot go forward until the commission works out how to comply with regulations about how upfront payments from bidders are held.
