First independent 5G results: Hundreds of megabits, not gigabits - Sep 2018
"Pal Zarandy, an always interesting analyst, tested Elisa's "world's first" 5G network from inside his office and outside with line of sight. The results were as expected: 5G at 3.5 GHz and Massive MIMO performs about the same as a good 4G network."

"This is the dirty secret of "5G." Almost all the claimed new uses can be met with 4G. Anyone who doesn't know that should ask an engineer."

South Korea’s 5G auction stands up well to international benchmarks | PolicyTracker: Jul 2018
"Winners of the 3.5 GHz frequencies received a 10-year licence, while the 28 GHz frequencies have just a five-year term, both significantly less than is usually the case for 3G or 4G licences. However, the short terms do not appear to have acted as a brake on bidding."

"The 3.5 GHz result is equivalent to $0.19 per MHz per pop, comparable to the $0.15 per MHz per pop raised in the recent sale of 3.4 GHz spectrum in the UK. That was a contest in which the four incumbents faced competition from an outsider."

"Given the lack of precedent for mmWave band auctions, benchmarking is harder for 28 GHz, but not impossible. The Korean sale is equivalent to $0.0045 per MHz per pop. By comparison, the US Federal Communications Commission is proposing to sell off frequencies at 28 GHz in mid-November this year with a minimum opening bid of $0.002 per MHz per pop, half the amount raised in Korea."

Ericsson: city 5G works well if just deployed on existing base stations | PolicyTracker March 2018
Vendor’s urban propagation mapping shows high indoor penetration at 3.5 GHz and 28 GHz with almost the same outdoor footprint as 2.6 GHz.

Kenneth Wallstedt, director of technology strategy at Ericsson, says the idea that a 5G network necessarily requires many more base stations is a “misunderstanding”.

GE backs localized area licensing at 3550–3700 MHz in US for industrial IoT | PolicyTracker: the spectrum management newsletter
"There are over 74,000 census tracts in the US and its territories. This would make nationwide spectrum access more complex than by PEA, of which there are 416. The added complexity had irked some mobile operators."

"GE says that entities wishing to provide geographically-targeted deployments would not be able to compete against mobile operators for PEA-based PALs"

"General Electric (GE) has the spectrum in mind for broadband-intensive (such as video) remote monitoring and the inspection of industrial equipment by drones, crawlers or submersibles. It would prefer to provide its own networks for these applications, rather than rely on wireless carrier services."

Operators commit to 5G trials but cut back on overall equipment expenditure | PolicyTracker: the spectrum management newsletter
"In spite of these positive announcements, mobile operators are still at the pre-investment stage when it comes to deploying 5G networks and that is not simply because the ITU and 3GPP standards are not available. Identifying use cases is still at the top of the operators’ agenda, prior to any investment in networks."

"Key characteristics of 3.4-3.8 GHz spectrum like outdoor-to-indoor penetration are still uncertain, however, with Lombardi telling PolicyTracker she has read about trials of “not very efficient” outdoor-to-indoor penetration "

"Mobile revenue growth in Europe is 0.4 per cent, according to Telenor Norway chief executive Berit Svendsen. “In Norway, our customers are using 60 per cent more data,” she said. “Against 0.4 per cent revenue you have a problem to maintain your network, to build out more coverage.” She added that the company had been lucky in that it had been able to increase subscriber charges slightly"

Viewpoint: Is CBRS a help or hindrance in the 5G race? | PolicyTracker: the spectrum management newsletter
"So there is a strong argument that CBRS will actually enable the US to deploy a much higher capacity cellular system, with both frequencies for conventional outdoor deployment and also for excellent in-building coverage. Innovative approaches are likely to emerge to enable roaming between outdoor and indoor systems, load balancing with Wi-Fi and more. The US could end up as a global leader in what seems a much more likely network of the future than any 3.5 GHz outdoor solution."

Editor’s Corner—Google vs. T-Mobile, AT&T, Verizon in 3.5 GHz showdown | FierceWireless, Jul 2017
T-Mobile and CTIA created quite the upheaval when they proposed changes to the 3.5 GHz rules that were passed last year, once again pitting mobile carriers against the internet giant Google and a lot of smaller companies, including WISPs that are serving rural areas, a particular area of interest for one FCC chairman in particular.

In one corner, you’ve got T-Mobile, CTIA, AT&T, Verizon, Qualcomm, Ericsson and others. In the other corner are Google, Alphabet’s Access group, the City of New York, Starry, the Dynamic Spectrum Alliance, Ruckus Wireless, Rise Broadband and a host of smaller wireless ISPs.

A year in, what’s happening with Google, Verizon, Nokia and the 3.5 GHz CBRS band? | FierceWireless Apri 2017
"Yet if the 3.5 GHz band goes commercial and is ultimately successful, it could pave the way for a whole new way of using spectrum: by sharing it. And even though wireless carriers were not 100% behind the concept a year or so ago, they’re jumping on board the 3.5 GHz train now."

"What’s driving a lot of momentum currently is the CBRS Alliance, which was formally unveiled in August by six companies: Google, Federated Wireless, Nokia, Qualcomm, Intel and Ruckus Wireless. Since then, the organization has grown to include more than 30 companies, including all four nationwide U.S. wireless operators. "

Federated Wireless, Alphabet's Access hit milestone ahead of 3.5 GHz sharing | FierceWireless Dec 2016
"To accomplish the interop demo, engineers from Federated Wireless and Access, who have been working together over the past weeks and months, staged a conference call Dec. 1 between Federated Wireless’ offices in Boston and the Access team in Mountain View, California, so that they could observe the demo, which used Amazon Web Services (AWS) on Federated Wireless’ side and Google Cloud for Access. The two cloud systems worked together over the air to conduct SAS interoperability—which in the old days before software-defined tech would have required them to physically sit next to one another in a lab."

Google sees CBRS spectrum band as key for 5G, new model for industry
"Speaking at this week’s 5G North America event, Preston Marshall, engineering director for Alphabet Access at Google, based a discussion on the internet search giant’s attempt to oversee the Spectrum Access System set to be the intermediary on spectrum sharing in the 3.5 GHz band. With this model, Marshall said the traditional role of telecom operators spending billions of dollars to gain control of specific spectrum blocks is no longer valid.

“This changes what spectrum ownership means,” Marshall said. “There is no owner.”"

"While traditional wireless carriers have expressed interest in the 3.5 GHz spectrum, Marshall said he thinks the killer application for the band is a neutral host concept, noting the benefits of having robust spectrum support using common backhaul and common management of devices not tied to a single network provider. This nontraditional model could also play into the evolving usage model of wireless services, with Marshall explaining most growth is happening indoors, which could be difficult for established mobile operators to tackle using standard deployment models."

Chinese industry talks up the potential of 3.5 GHz for TD-LTE -- PolicyTracker Oct 2015
"The growing popularity of TD-LTE, which is considered more flexible than FD-LTE because it does not need to be deployed using paired spectrum, owes a great deal to the economies of scale created by the Chinese government’s decision to prioritise licensing spectrum for it. " "In addition to the legal complexity surrounding the band’s treatment in the Radio Regulations, another barrier to using the band is mobile operators' lack of interest in it."

Ofcom proposes indefinite 3.5 GHz licence for UK Broadband - PolicyTracker Oct 2014
"Last autumn, Ofcom proposed to amalgamate the unused spectrum into one contiguous 40 MHz block (3560–3600 MHz) by swapping UK Broadband's lower spectrum holding with spectrum that is currently held by the Ministry of Defence (MoD). . . In the same consultation, Ofcom also proposed to extend the licence indefinitely in order to mirror conditions in the 800 MHz and 2.6 GHz band, which are also used for mobility. UK Broadband's current licence is due to expire in July 2018. . . However, by June 2014, Ofcom had changed its proposal to just extending the licence indefinitely, without spectrum consolidation. . . Ofcom's proposal was partly influenced by UK Broadband's refusal to invest in a network if they were not granted an indefinite licence." "Globally, the fixed wireless broadband business model has proven to be difficult to make work, especially with higher frequencies such as 3.5 GHz which have poorer propagation characteristics” said Scott McKenzie, a director at Coleago Consulting.

3.5 GHz spectrum-sharing database 'could get very complicated,' says Accenture exec - FierceWirelessTech July 2014
"Shahid Ahmed, managing director and North America communications industry and network practice lead at Accenture, said the 3.5 GHz database, or databases, will have to track and enable spectrum sharing based on three dimensions: geolocation, time and spectrum frequency. Devices will need to contact the SAS, provide their geolocation coordinates, request transmit approval and get assigned a usable frequency. "I think the database technology's there. It's just a matter of transitioning to this model and getting all of the players together to agree on some of the policies," Ahmed said. He noted that transitioning incumbents to the new model will likely pose challenges. urther, there remain lots of questions regarding the proposed 3.5 GHz database, including how it should be architected, how it will be managed and who should manage it, said Ahmed. The SAS "is going to be more or less like an HLR (home location register). It's going to be very dynamic..." ""

3 companies in ex parte "joined to support the three-tiered sharing framework proposed by the President's Council of Advisors on Science and Technology (PCAST) for the 3.5 GHz band." "AT&T's support for the 3.5 GHz spectrum-sharing scheme laid out in the July 2012 PCAST report represents a significant departure from the telco's original reaction to the plan." "also discussed ways, unspecified in the ex parte filing, that the FCC might structure the 3.5 GHz spectrum-sharing framework to enable experimentation and substantial use by general authorized access (GAA) devices for the Citizens Broadband Service" "also said they back broad eligibility in the priority access tier; use of a spectrum access system to manage interference protection; and lightweight auction mechanisms where necessary to resolve mutually exclusive requests for priority access reservations."

Qualcomm wants LTE deployed on unlicensed spectrum - FierceWireless
Quotes: Qualcomm (NASDAQ:QCOM) is interested in exploring the possibility of deploying LTE services on unlicensed spectrum, according to CEO Paul Jacobs. According to Electronics Weekly, Jacobs explained the reasons behind the move: "We paid for that very sophisticated LTE receiver in the devices, it's a better receiver than the receiver that's been used for Wi-Fi. That means you get better capacity and better coverage out of an LTE unlicensed deployment." It's unclear which bands could be used for unlicensed LTE services. One that has been bandied about is the 3.5 GHz band, which is being eyed for small cells in the United States.

Military Considers Sharing Radar Frequencies with Wireless Networks | MIT Technology Review
"While commercial wireless networks are congested, frequencies set aside for military purposes are lightly used. Now wireless researchers and the U.S. Navy will get a chance to see whether some of those airwaves can be shared, which could lead to innovative new services. In a test on Monday, the Navy will fire up an AN/SPY 1 radar—a powerful system that normally scans for incoming missiles and bombers—on an island off Virginia’s eastern shore. At the same time, visiting academic and corporate researchers will tune portable wireless transmitters to the same frequency to see what happens."
