Panelists at the HPA Tech Retreat agreed with PBS’s Eric Wolf: “Channel sharing is a reasonable option for people to look at, but at the end of the day management has to look at this and say we can take a one-time infusion of cash from the auction and give up forever some portion of our spectrum, which is our bread and butter, and forgo a lot of future options.” But panelists weren’t in harmony on every issue. CBS’s Bob Seidel (l) and Sinclair’s Mark Aitken disagreed on the approach to the next-gen TV standard ATSC 3.0.
MAA- From this compiled piece, I walk away with this quote emblazoned…”The real wireless revolution here is not communication – it’s power. And it’s just getting started…” Imagine of Tesla’s vision of Wireless Power Transmission of energy was widely available?! Gamechanger of a different sort…
Before I get into the technical evaluation of Artemis’s demo videos and much-ballyhooed claims in the press, let’s cut through the hype:
Is this going to revolutionize wireless communications? While these demos alone don’t necessarily demonstrate speeds beyond what is theoretically capable with LTE systems today, I think the evidence is clear that this technology can offer a solution to the “spectrum crunch” problem, so I’d say yes. From a mobile consumer’s standpoint, it’ll just seem like the next step in evolution from 4G to 5G – much faster, more consistent speeds, and with lower latency. Now, whether or not it actually gets deployed by carriers is another matter all together.
Is this invention completely unique? No! Just last year, a German university demonstrated a working prototype of essentially the same technique (albeit without a snazzy streaming video demo or compatability on traditional cell phones) in the video here. The theory behind this sort of system is referred to as “network MIMO” or “cooperative MIMO” in the literature and “coordinated beamforming” in the 3GPP LTE-A specification , and dates back to 2001, if not earlier  . But then again, when is an invention ever done in a vacuum? Calculus, the telephone, and the Hall-Heroult process for smelting aluminum were all discovered simultaneously. What Artemis has done is taken techniques that are being proposed for upcoming 5G systems and figured out how to solve all the engineering challenges involved, years ahead of the rest of the industry  .
Have they broken the Shannon limit? No, they’ve just side-stepped it. Each user now has their own channel, and can use it up to the full Shannon limit without having to share it with anyone else. See the section of their whitepaper beginning with “Shannon’s Law is not about spectrum data rate limits, it is about channel data rate limits”.
Under an uneasy truce with broadcasters ahead of the FCC’s 2015 spectrum auctions, government leaders, spectrum dealers and wireless industry promoters are dangling projections of huge cash infusions for public TV stations that opt to sell some or all of their channel capacity.
There’s no doubt that stations in some of the top 10 markets may reap big payoffs if they opt to participate, or that the public TV system could benefit from channel repacking that reduces duplicative signals. But as visions of sugarplums dance in the heads of station executives and their board members, I hope that these stewards of the nation’s noncommercial spectrum also see the bright-red flag that signals “Seller Beware” (caveat venditor in Latin).
Small base stations could achieve huge data capacity increases using Intel’s modular antenna arrays.

Why It Matters
Data demand is expected to surge in the coming years, requiring better wireless technologies.
Intel says it has prototyped a chip-based antenna array that can sit in a milk-carton-sized cellular base station. The technology could turbocharge future wireless networks by using ultrahigh frequencies.
Intel’s technology, known as a millimeter wave modular antenna array, is expected to be demonstrated today at the Mobile World Congress conference in Barcelona, Spain, says Ali Sadri, director of the millimeter wave standards and advanced technology group at Intel.
Steve Perlman, the guy behind WebTV and OnLive, has revealed his next (hopefully) game-changing innovation: pCell wireless technology. If early demonstrations of the technology are to be believed, pCell appears to completely dismantle the idea of a “wireless spectrum crunch,” allowing each mobile device to receive full wireless bandwidth from congested base stations, potentially increasing our total wireless bandwidth by 1,000x. Perlman and his new company, Artemis, are now looking for strategic partners to bring pCell tech to market. We could be looking at one of the biggest revolutions in wireless communications — but there still some big questions about the technology’s efficacy and scalability to answer before we get too excited.
Huawei and Vodafone GroupVOD.LN +0.02% announced that they have figured out a way to let mobile carriers combine two variants of 4G service, paving the way to more efficient use of wireless spectrum.
