‘First’ prototype hardware built for broadband over IEEE’s white space standard

'First' prototype hardware developed for broadband over dead analog TV spectrum

If you hadn't realized already, spectrum is quite the hot commodity, and any unused slice is a potential data highway just begging to be cruised. One mostly vacant stretch is the eerie white space -- megahertz left empty when TV broadcasts move from analog to digital frequencies. The IEEE published its 802.22 standard for white space broadband 18 months ago, and now a group comprising the NICT, ISB Corp and Hitachi Kokusai Electric (not to be confused with the other Hitachi) have built the "first" prototype hardware to make use of it. White space spectrum in the 470 to 710MHz range is expected to provide wireless internet to "underserved areas" and act as an emergency backup for downed systems, when infrastructure is finally up and running. Given we're only at the prototype stage following the inception of the 802.22 standard in 2011, out-of-towners will probably be waiting a while longer before having the option to stream entertainment over those dead TV airwaves. Fate, it seems, is not without a sense of irony.

World's First TV White Space Prototype Based on IEEE 802.22 for Wireless Regional Area Network

TOKYO, Jan. 23, 2013 /PRNewswire/ -- The National Institute of Information and Communications Technology (NICT), Hitachi Kokusai Electric Inc. and ISB Corporation have developed the world's first prototypes of base station (BS) and consumer premise equipment (CPE) based on the IEEE 802.22 standard operating in TV White Spaces (TVWS) (470 MHz - 710 MHz). The developed prototypes will provide broadband wireless access to underserved and unserved regional areas around the world as well as bringing reliable backup broadband communications in emergency, which will follow the worldwide trend of promoting the TVWS for wireless communication systems.

Background
From replacing the current analog television (TV) technology with digital television technology, some of the spectrum previously used by analog television become vacant referred to as TV White Space (TVWS). The Federal Communications Commission (FCC) in the United States, the Office of Communications (Ofcom) in the UK, and the Ministry of Internal Affairs and Communications in Japan have initiated opening up the TVWS to wireless communication systems for efficient reuse of the unused TV spectrum, which is based on non-interfering with broadcast incumbents' operation. The IEEE 802.22 Working Group has published the IEEE 802.22-2011 standard for TVWS broadband wireless access to regional areas where it is most needed and where the TV spectrum is least used. In particular, the IEEE 802.22 systems offer around 10 times the coverage of Wi-Fi as well as enable to provide reliable backup broadband communications in emergency. However, there is no TVWS systems based on the IEEE 802.22-2011 satisfying the FCC spectrum requirements.

Achievements
The NICT and Hitachi Kokusai Electric Inc. have developed the world's first prototype devices of base station (BS) and consumer premise equipment (CPE) verifying the physical layer (PHY) and the medium access control (MAC) layer design based on the IEEE 802.22 standard in the TVWS (470 MHz - 710 MHz). The PHY part developed by Hitachi Kokusai Electric Inc. (Note 1) allows the devices to use vacant TV bands over the frequency range from 470-710MHz, the MAC layer part developed by NICT provides a medium access method based on point-to-multipoint access with supporting the different QoS levels, and supports cognitive capabilities of interference estimation, geo-location and white space data base (WSDB) access over the IP. The WSDB (Note 2) (http://whitespacetech.isbcorp.com/) provided by ISB Corporation avoids interference to incumbents of TV broadcasters from automatically selecting the non-interfering TV band.

Future prospects
The NICT, Hitachi Kokusai Electric Inc. and ISB Corporation in the future will develop the enhanced technologies based on the IEEE 802.22 standard and also work closely with WhiteSpace Alliance (WSA) (Note 3) (www.whitespacealliance.org) to provide products for worldwide markets. The NICT, Hitachi Kokusai Electric Inc. and ISB Corporation will demonstrate the developed prototype devices at the Super WiFi Summit (Note 4) (www.superwifisummit.com) in Miami, Florida, from January 30 to February 1, 2013.

Dish’s AWS-4 wireless spectrum standards approved by 3GPP

Dish's AWS-4 wireless spectrum standards approved by 3GPP

Dish has edged one step closer to its distant goal of having a 4G LTE network to call its own, receiving approval for its AWS-4 (40MHz) wireless spectrum standards by the 3GPP group. Dish used the announcement to air a few issues, including sending a plea to the FCC to get a move on and officially green light the frequency for use. The would-be wireless provider also sounded off on Sprint, which is asking the FCC to crop some of Dish's spectrum and add it to the H Block, making it a more attractive acquisition when auctioned off. If the FCC were to grant Sprint's request, Dish wouldn't just lose airwaves, but the slow approval process would start anew with altered specifications. Unfortunately for the satellite TV outfit, Sprint is far from the only potential competitor trying to delay Dish's network -- in fact, none seem particularly willing to welcome the new guy without some serious hazing.

Leap Wireless swaps spectrum with T-Mobile, buys all of Savary Island

Leap Wireless and TMobile completes spectrum swap, buys all of Savary Island Wireless

Leap Wireless can go ahead and pop the champagne, as it has just completed the spectrum transactions announced earlier this year that will hopefully lead to larger LTE growth. Leap's own Savary Island Wireless exchanged spectrum with T-Mobile USA and Cook Inlet/VS GSM VII PCS LLC (itself a T-Mo business), resulting in Cricket's parent company acquiring 10MHz of additional AWS spectrum in Phoenix, AZ and Houston, Galveston and Bryan-College Station, TX, among others. In return, T-Mobile received spectrum in various markets in Alabama, Illinois, Missouri, Minnesota and Wisconsin. There are also several intra-market exchanges in Philadelphia, Wilmington, Atlantic City, New Mexico, and Texas. In addition to the spectrum exchange, Leap also formally acquired the entirety of Savary Island Wireless for around $5.3 million (It previously only owned an 85 percent share) so the company has even more cause for celebration. Just don't overindulge on the Cristal, okay Leap?

FCC votes in favor of rethinking spectrum holding rules, goading broadcasters into wireless selloffs

Posted on by

Cellular tower worker

FCC meetings can be momentous occasions under the right circumstances, although it's seldom the case that we see the agency pass two potentially far-reaching measures in one sitting, like we just saw on Friday. To start, regulators have voted in favor of a proposal that will review spectrum sale rules and might drop the case-by-case determinations in favor of a more consistent screening mechanism. The reexamination will also consider a change to the ownership rules surrounding wireless frequencies that treats bands below 1GHz differently than those above -- the better to address a chorus of smaller carriers that don't like all the prime spectrum going to the companies with the most existing clout, namely AT&T and Verizon. FCC Chairman Julius Genachowski argues that reform could spur innovation through more competition, although dissenting Commissioner Robert McDowell is worried that consistent rules will somehow create "uncertainty."

Side-by-side with the review, the FCC is proposing an incentive-based reverse auction strategy to have TV broadcasters voluntarily give up their spectrum for cellular and data use. The multi-phase approach would have TV providers set the price at which they're willing to sell their spectrum to the FCC; those that just can't bear to part with their airwaves would be corralled into a tighter band range to make for larger available frequency blocks in the auction that follows. As with other FCC proposals, there's likely to be a long interval between the auction vote, the review and any definitive rulemaking, let alone an impact -- auctions by themselves can take years to play out. Still, any success with the measures could head off spectrum crunches while simultaneously preventing any solutions from consolidating too much power and creating their own problems.

FCC chairman green-lights AT&T’s use of WCS spectrum for LTE with proposed order

Posted on by

AT&T is close to securing a major victory in its battle against the spectrum crunch. While it's not quite a done deal, FCC chairman Genachowski has submitted a proposed order to FCC commissioners that would authorize AT&T's deployment of its LTE service within a 20MHz portion of the 2.3GHz (WCS) band. The deal is unique in that the spectrum is currently reserved for satellite radio, and the reallocation would mark the first of its kind within the WCS band. As you may recall, AT&T previously conceded to a 5MHz dead zone on both ends of Sirius XM's operating frequency in order to mitigate interference concerns, and it seems the move was sufficient to gain the chairman's support.

Also looming on the FCC's to-do list is the decision of whether to approve AT&T's purchase NextWave and its unused WCS spectrum. If it's any indication, however, Chairman Genachowski seems bullish on the reallocation and has suggested that the agency may authorize another 30MHz of the WCS band for mobile broadband use. AT&T has previously said that it could feasibly deploy LTE over the 2.3GHz spectrum within the next three years. One group fighting the deal is the Competitive Carrier Association, which posits that AT&T's purchase of such a significant chunk of spectrum on the secondary market is anti-competitive in nature. It'll no doubt be interesting to see if the argument gains any traction with the FCC. In the meantime, you can view remarks from the agency's spokesperson after the break.

FCC to vote September 28th on proposal auctioning UHF spectrum, Weird Al might still approve

FCC to vote on September 28th on proposal auctioning off UHF spectrum, Weird Al might still approve

The FCC has been more than a little eager to repurpose spectrum as wireless internet access takes off: white spaces and iDEN frequencies have already switched roles, and that's not including the myriad of spectrum swaps. Add one more wireless variety to the list, as FCC Chairman Julius Genachowski has confirmed his agency will vote on a proposal for incentive-based auctions of UHF spectrum. When the Commission meets next on September 28th, it will decide on whether or not to lure broadcasters into giving up the usually TV-focused space for the sake of data lovers everywhere. The freed-up airwaves in the proposal would mostly be unlicensed spectrum with "WiFi-like uses," but at a much lower frequency than the 2.4GHz and 5GHz bands that WiFi needs today: as the first consistent, unlicensed spectrum at that range in the US, it could create opportunities for longer-ranged, free wireless that aren't even on the table in 2012. Not that we have much of a choice in taking action today. Any accepted rules won't be completely finalized until mid-2013, and the auction itself won't take place until 2014. Still, the UHF plans foster dreams of more wireless for everyone -- and we suspect that even one Mr. Yankovic wouldn't mind giving up Channel 62 for a long-distance home network.

FCC seen reviewing rules for carrier spectrum sales, might try one-size-fits-all model

FCC seen reviewing rules for carrier spectrum sales, might try onesizefitsall model

The FCC currently decides on concerns of wireless spectrum concentration on a case-by-case basis: what's acceptable in one deal might be forbidden in another. That inconsistency can be maddening to carriers and advocacy groups alike, which is why FCC Chairman Juilus Genachowski is reportedly on the cusp of distributing an order to review the process. Talking to The Hill, an official at the agency claims that the review would ask for input on creating a universal standard that would apply to all deals, hopefully providing "clarity and predictability" for any company making a spectrum grab. The order could be distributed to the FCC's commissioners next week and voted on next month, although there's no sign of an impending revolution -- it's just a call for opinions, after all. Regardless, the two sides of the spectrum debate already like the idea, as it could both prevent complaints by carriers of ambush regulation as well as toughen up rules that critics say hands too large a slice of the airwaves to the incumbents.

DOJ, FCC clear Verizon buyout of cable companies’ spectrum, require giving up some airwaves

Posted on by

Verizon logoVerizon has been fighting hard to get its acquisition of cable companies' wireless frequencies past legal hurdles, and it just surged over the most important of the bunch: both the Department of Justice and the FCC have signed off on the agreement. To get the $3.9 billion deal through the door, Big Red will have to offload some of its spectrum to other companies. The DOJ, meanwhile, is more concerned that Verizon is getting a little too cozy with Bright House, Comcast, Cox and Time Warner Cable in terms of marketing and reselling bundles that include cellular and cable access. Closing the deal also requires setting up a new joint venture in technology research. We're still working to learn the full details of the deal, but the spectrum handover will likely give a swift kick to Verizon's 4G capacity -- and anger a few rivals who wouldn't have wanted any handover to go through.

AT&T agrees to acquire NextWave for $600 million, gobbles up WCS and AWS spectrum

AT&T agrees to acquire NextWave, gobbles up more spectrum

AT&T's making no secret of the fact it wants to snatch up as much spectrum as it possibly can, so news of the company's proposed acquisition of NextWave Wireless doesn't result in much of a shock. AT&T has agreed to purchase the company -- and all of its WCS (Wireless Communication Service) and AWS spectrum licenses and equity along with it -- for $25 million, pending FCC approval. If you count $25 million in contingency costs and the outstanding debt the big blue globe has also picked up, however, the total bill climbs to $600 million.

The deal comes shortly after AT&T partnered with Sirius XM to petition the FCC in the hopes that it would allow WCS (2.3GHz) spectrum to be opened up for LTE use -- mobile data is currently restricted by the federal body to prevent any interference with satellite radio. The government hasn't given the green light for this proposal yet (additionally, the NextWave deal isn't likely to be approved until later this year), but that's not stopping AT&T from its preparations just in case -- it plans to have WCS LTE ready for deployment in three years if everything works out in the carrier's favor.
