Update: Comment Deadlines Set In BRS/EBS Rulemaking

Last week we reported on a proposal to relax out-of-band emission limits for the Broadband Radio Service (BRS) and the Educational Broadband Service (EBS), operating in the 2496-2690 MHz band (a/k/a the 2.5 GHz band). Acting with impressive speed, the Commission has now published that NPRM in the Federal Register. That, in turn, sets the dates for comments and reply comments. As we indicated in our original post, the comment periods seem somewhat abbreviated – comments are due by July 7, 2011, reply comments by July 22 – so if you’re of a mind to submit some thoughts to the Commission, you should probably get on it sooner rather later.

Broader Broadband For 4G Networks?

FCC contemplates relaxation of out-of-band emission limits in the 2.5 GHz band.

The FCC has proposed to relax out-of-band emission limits for the Broadband Radio Service (BRS) and the Educational Broadband Service (EBS), operating in the 2496-2690 MHz band (a/k/a the 2.5 GHz band). These services were formerly known as MMDS and ITFS. Their spectrum is now largely leased to Clearwire, Nextwave, and others for 4G mobile broadband services.

Clearwire is the largest current user of the band. It relies on WiMAX technology, which typically utilizes 10 MHz channels. But Clearwire and other service providers are thinking that wider bandwidths might be in order. Clearwire would like to migrate to WiMAX2, while other service providers (and maybe Clearwire as well in the future) are considering Long Term Evolution-Avanced (LTE). Both WiMAX2 and LTE contemplate channel bandwidths of 40-100 MHz.

At first blush, there doesn’t seem to be much reason why the FCC should not allow operators to choose their own bandwidth, and thereby improve 4G broadband performance. Except for one thing: it isn’t as easy – or cheap – to mask out-of-band emissions as sharply when using a broader desired bandwidth as it is when using narrower bandwidth. Faced with this conundrum, the Wireless Communications Association International (WCAI) asked the FCC to loosen the mask.

Ouch! cried some of the people who use adjacent bands for things like Mobile Satellite and TV Broadcast Auxiliary Services. Don’t tread on me!  Spicing things up, one developer/manufacturer of LTE-Advanced gear chimed in that it can produce 20 MHz bandwidth equipment that complies with the existing out-of-band limits. In this manufacturer’s view, no relaxation of the current mask is necessary because the equipment it makes will take care of the problem even at the broader bandwidths. 

According to WCAI, however, other equipment manufacturers support the proposed relaxation as “an appropriate and reasonable trade-off between form factor, battery consumption, and performance”. Worry not, says WCAI, because our mobile units normally don’t occupy the entire bandwidth, and they keep their power low to conserve battery capacity – so overall, the benefits of a relaxed mask outweigh the risks.

What shall we do with no consensus, the FCC asks? A mitigation rule is already in place that requires base stations to comply with a tighter emission mask within 60 days of receiving a documented interference complaint. Mobile devices operate with lower power and do seem to be less of a threat. So the Commission reasons that maybe it can lighten up – but should it also anticipate future bandwidths even wider than 20 MHz, and should it change mobile mask limits to make it easier and cheaper to make those ever-smarter devices without which no self-respecting teenager or twenty-something would be seen on the street?

Comments will be due 30 days after the proposals are published in the Federal Register, with Reply Comments only 15 days later. Those short times suggest the FCC does not expect a major brouhaha. It remains to be seen whether they guessed right.

BRS/EBS Update: Comment Deadlines Are Set

Two weeks ago we reported that the FCC has proposed some changes in the Broadband Radio Service/Educational Broadband Service (BRS/EBS). Those proposals have now made it to the Federal Register, which in turn establishes the deadlines for comments and replies on the proposals. As we observed in our initial post, the comment periods are short: comments are due by October 13, replies by October 23. You can find the full text of the FCC’s proposal here.

Educational Broadband Service Issues Resolved

EBS leases grandfathered, other loose ends tied down, new build-out terms proposed

The status of hoary Educational Broadband Service leases has been up in the air ever since the FCC made EBS leases subject to the secondary market rules that govern most other spectrum leasing arrangements. But now, thanks to a long-awaited ruling on (among other things) an uncontested compromise proposal, things may start moving again.

The principal issue has been: how long can these EBS leases extend? Originally, such leases were limited to ten years . . . then 15 . . . then there was no limit . . . then (in 2008) the Commission re-imposed the 15-year limit, grandfathering pre-existing leases from the date of execution of the leases.  

In the FCC’s back-and-forth flip-flopping, it was that latter flip (or was it a flop?) that raised the dander of many EBS lessees – particularly those with leases which (a) may have been “executed” many years ago but (b) have not gone into effect because the start date on the leases was triggered by some other event.   The FCC’s casual ruling – perhaps inadvertently –served to severely limit the term of some such leases.

Reconsideration petitions were duly filed and opposed, but eventually the commercial industry group (WCAI) and the educational industry group (NEBSA) jointly offered a compromise solution: the 15 years could run from the execution date if the lease had in fact commenced prior to March 20, 2008 (the date of the Order that caused all the hubbub) or if both parties to the lease agreed to its treatment as grandfathered.   The joint proposal also provided that leases entered into between January 24, 1999, and January 5, 2005, that provided for deferred start dates on the leases would be grandfathered for up to 15 years from the agreed start date (rather than from the execution date).

The FCC gladly accepted this compromise proposal (which to our mind leans heavily in favor of the commercial lessees) as meeting most of the interests of both parties. It also was able to avoid the deeper question of whether the FCC can abrogate contracts by administrative fiat.

Cleaning up another loose end, the FCC proposed to give auction winners in upcoming Auction 86 four years from the date of their new licenses to build out their systems rather than the 15 months or so that would be available without a rule change. This much needed revision – if ultimately adopted – would come too late, however, for prospective auction participants who were deterred by the short construction fuse from filing short form applications. Comment deadlines on this proposal have not yet been established, but the comment and reply comment periods will be short (15 and 25 days from Federal Register Publication for comments and reply comments, respectively).

Finally, the FCC clarified that licensees of old channels 1, 2 and 2A can simultaneously operate on both their old channels and their new channels pending migration of all of their subscribers to the new band plan.   So theoretically, if an AWS licensee does not evict the incumbent BRS licensee from the old band, it could continue to operate on those 6 - 10/12 MHz of spectrum indefinitely by keeping subscribers on the bands.   Not that anyone would ever do such a thing.
