mmWave 5G real-world deployments will require very dense networks: report | FierceWireless apr 2019
"Moore conducted his tests using the Motorola Z3 handset with the 5G Moto Mod adapter. Verizon gave him a list of nine cells, and he tested about six of them while walking around Chicago.

Moore said he received a top speed of 500 Mbps during his tests. “It’s very zippy under favorable conditions with line of sight,” he said, but added that mmWave doesn’t penetrate obstacles and it doesn’t travel far."

“Moore said he tested the signal speed through a pane of glass in a restaurant that was only about 25 yards away from a cell node. “I found that the speeds were roughly halved from what I was getting outside on the street,” he said. The initial real-world 5G network tests make clear the 5G networks that use mmWave spectrum will face a lot of challenges. “It requires a very, very dense network,” Moore said.”

Australian regulator backs unusual hybrid approach for 26 GHz award - PolicyTracker: spectrum management news, research and trainingPolicyTracker: Apr 2019
"A combination of spectrum, apparatus and class licences is the best way to support the three different scenarios on offer in the 24.25—27.5 GHz band, according to the decision paper ACMA published last week."

"The approach would see 2.4 GHz of spectrum (25.1–27.5 GHz) set aside for the mobile industry to offer 5G. However, this chunk is only available in metropolitan areas and large regional centres. It will be auctioned, as is traditional in Australia.

The 27-27.5 GHz part of the band has additional conditions attached to protect an existing satellite gateway.

Elsewhere, the same spectrum will be awarded on an “apparatus” basis. Apparatus licences authorise the licensee to operate devices to which the specific licence relates, such as specific types of transmitter or receiver. Normally, that does not imply an auction in Australia, although the paper says “authorisation may be under a potential new ‘spectrum-space’ area-based apparatus licence type”. It is unclear how this new type of licence will be awarded."

Japanese operators vie for lower band 5G spectrum | PolicyTracker: Feb 2019
"Japan’s forthcoming spectrum award will be the first for 5G decided by a beauty contest rather than an auction. This is not the only thing that makes it unusual. "

"Over the past 12 to 18 months, Japan has debated the possible use of auctions to assign spectrum but ultimately decided to maintain its favoured approach of using beauty contests. Other countries have used auctions for 5G but Japan is sticking with what it knows best."

"MIC is awarding six blocks of 100 MHz in the more desirable lower bands (3.7 GHz and 4.5 GHz), and four blocks of 400 MHz at 28 GHz."

"Also interesting is MIC’s decision to pick out some frequency ranges for industry or specific applications."

"The government has complained recently about high mobile prices. Senior officials have accused operators of using spectrum, a public asset, in the pursuit of excess profits."

It’s official: 37, 39 and 47 GHz bands headed for incentive auction in 2019 | FierceWireless Dec 208
As expected, the FCC voted to move forward with an incentive auction that combines the upper 37, 39 and 47 GHz bands, delivering a nice gift to the wireless industry.

The airwaves in the combined upper 37 and 39 GHz bands represent the largest amount of contiguous spectrum available for wireless service in the millimeter wave bands—2,400 megahertz in total—while the 47 GHz band provides an additional 1,000 megahertz of spectrum.

The auction, slated for the second half of 2019, will take place in two phases: a clock phase in which firms may bid on generic license blocks, and an assignment phase in which clock phase winners may bid on specific frequencies. Incentive payments will be offered to incumbents that choose to relinquish their spectrum usage rights to make new licenses available.

Electromagnetic Radiation Safety: 5G Wireless Technology: Millimeter Wave Health Effects
"Unfortunately, few studies have examined prolonged exposure to low-intensity MMWs, and no research that I am aware of has focused on exposure to MMWs combined with other radiofrequency radiation."

"In sum, the peer-reviewed research demonstrates that short-term exposure to low-intensity millimeter wave (MMW) radiation not only affects human cells, it may result in the growth of multi-drug resistant bacteria harmful to humans. Since little research has been conducted on the health consequences from long-term exposure to MMWs, widespread deployment of 5G or 5th generation wireless infrastructure constitutes a massive experiment that may have adverse impacts on the public’s health."

EU institutions reach agreement on Electronic Communications Code | PolicyTracker June 2018
"It adds that countries must allow the use of at least 1 GHz of the 26 GHz band, provided there is clear evidence of market demand and no significant constraints from existing users. The 32 GHz and the 40 GHz bands have also been identified as priority bands for 5G deployment.

The code says the EU welcomes increased cooperation among member states in spectrum management but underlines that spectrum usage varies across the Union and that flexibility for national governments must be preserved. For instance, the EECC proposes that the Body of European Regulators for Electronic Communications (BEREC) will issue standardised declarations for service providers, but national regulatory authorities (NRAs) will continue to have the lead role in general authorisations. "

“Peer review should contribute to a better exchange of best practices between Member States and increase transparency… but it should not be a formal condition of national authorisation procedures,” the draft document says. The peer review of national spectrum assignments will be led by the European Commission’s advisory body the Radio Spectrum Policy Group (RSPG), not BEREC.

"The decision to increase spectrum licences to 20 years, short of the 25 years the industry wanted, aims to secure return on investment."

PHAZR seeks OK to test Quadplex technology in high and midband spectrum | FierceWireless June 2018
Startup PHAZR is asking the FCC for an experimental license to test its Quadplex technology that pairs high-band millimeter wave spectrum for downlink with midband spectrum for the uplink to enable 5G systems.

PHAZR, which works with 3 of the 4 biggest U.S. carriers but doesn’t identify them, is seeing an increased interest on pairing millimeter wave spectrum for downlink with sub-6 GHz spectrum for the uplink.

PHAZR CEO Farooq Khan said the industry over the past two months or so has come to the realization that uplink on millimeter wave is going to be cost-prohibitive because the links need to be close together and there needs to be more of them—perhaps 10 times more.

"The ‘Study on using millimetre waves bands for the deployment of the 5G ecosystem in the Union’, which was launched in December 2017 and is being carried out by IDATE and Plum, suggests that mm-waves will constitute less than 1% of the total 5G market in terms of subscriptions by 2025. "

"According to interim results presented at a workshop, only localised specific applications and very dense areas will initially benefit from mmWave spectrum."

"Frédéric Pujol, head of radio technologies & spectrum practice at IDATE DigiWorld, predicted that the development of fixed wireless access (FWA)–using millimetre wave frequencies to provide in-building service, will be relatively low within the Union"

Exposure of Insects to Radio-Frequency Electromagnetic Fields from 2 to 120 GHz | Scientific Reports
Abstract

Insects are continually exposed to Radio-Frequency (RF) electromagnetic fields at different frequencies. The range of frequencies used for wireless telecommunication systems will increase in the near future from below 6 GHz (2 G, 3 G, 4 G, and WiFi) to frequencies up to 120 GHz (5 G). This paper is the first to report the absorbed RF electromagnetic power in four different types of insects as a function of frequency from 2 GHz to 120 GHz. A set of insect models was obtained using novel Micro-CT (computer tomography) imaging. These models were used for the first time in finite-difference time-domain electromagnetic simulations. All insects showed a dependence of the absorbed power on the frequency. All insects showed a general increase in absorbed RF power at and above 6 GHz, in comparison to the absorbed RF power below 6 GHz. Our simulations showed that a shift of 10% of the incident power density to frequencies above 6 GHz would lead to an increase in absorbed power between 3–370%.

Part of FCC order says ‘no’ to mobile industry trade groups, sticks with sharing in 37 GHz band | FierceWireless May 2018
"... the FCC rejected recommendations by CTIA, CCA, 5G Americas and T-Mobile to adopt exclusive area licensing in the 37-37.6 GHz band. Instead, the commission said it’s sticking with its previous plan and finds it’s in the public interest to license a portion of the band on a nonexclusive basis and to license the remainder of the band by geographic area to give potential licensees additional opportunity to access large blocks of spectrum or to use 37 GHz spectrum in combination with, and similarly to, 39 GHz spectrum"

"The plan calls for licensing the lower 37 GHz band as six 100 megahertz channels, which will allow for a sufficient acquisition of spectrum by smaller users while still allowing for aggregation by larger entities, according to the report."

All-Silicon Active Antennas for High Performance 5G/SATCOM Terminals | 2018-02-15 | Microwave Journal
Active mmWave antennas are expected to be rolled out in unprecedented volumes over the next few years, fueled by the rapidly emerging 5G telecommunications infrastructure and high throughput satellite (SATCOM) markets. mmWave spectrum is attractive for these new high-capacity systems due to the availability of large bands of contiguous spectrum.

Using active antennas allows highly-directive antenna beams to be formed by physically-small apertures, which helps offset the higher path loss associated with these high frequencies. The highly-directive beams allow spectral reuse through spatial diversity. These planar antennas offer fast, steerable beams; low size and weight; and can be cost-effectively produced in high volume. Active antennas also provide excellent reliability, since there are no moving parts, and the failure of a few elements in the array has little effect on the overall antenna performance.

5G Fixed Wireless Access Array and RF Front-End Trade-Offs | 2018-02-15 | Microwave Journal
Editor’s Note: At the end of December, the 3GPP approved the 5G non-standalone new radio (NSA NR) specification, which defines how enhanced broadband services can be deployed using a 5G NR leveraging the existing LTE network. This NSA architecture will first be fielded—later this year—for fixed wireless access (FWA) services using mmWave spectrum, i.e., 28 and 39 GHz.

Qorvo and Anokiwave are two companies leading the development of the mmWave front-end technology for the active phased arrays that will power these FWA services. Each company has analyzed the system requirements and defined a unique approach to meeting them. Qorvo has chosen GaN, Anokiwave silicon. We are fortunate that this issue of Microwave Journal features articles from both, each stating the case for its technology choice. Regardless of which argument you favor, no doubt you will agree that both companies are doing excellent technology and product development, a key step to making 5G viable.

Verizon CEO: 5G trials going ‘extremely well,’ with expectations to deliver 1 Gbps | FierceWireless, Jan 2018
Verizon last year conducted trials in 11 markets and expects to commercially launch a fixed wireless service in three to five markets this year; the only market to be announced so far is Sacramento, California. Verizon has estimated the market opportunity for initial 5G residential broadband services to be 30 million households nationwide.

“The trials are continuing to go extremely well for us,” McAdam said, noting that Verizon has more than 200 sites up and online. “We continue to learn every day,” managing distances of up to about 2,000 feet and peak throughputs of 10 gigabits, all of which are much better than expected using millimeter wave spectrum.

T-Mobile presses for mmWave auction in 2018, says major carriers already acquiring significant holdings | FierceWireless, Jan 2018
If it wasn’t clear before, it is now: Wireless operators want to get their hands on more millimeter wave spectrum, and the more, the merrier. And smaller carriers are worried the deck is going to get stacked against them in favor of the largest operators.

Those themes continue to emerge through comments filed with the FCC as part of its Spectrum Frontiers initiative. The FCC has asked for input on how it should structure spectrum bands above 24 GHz for mobile radio services, and carriers aren’t shy about responding. AT&T, Verizon and T-Mobile, plus the industry association CTIA, are pushing for an auction in 2018, with T-Mobile in particular pointing to Verizon’s accumulation of millimeter wave spectrum on the secondary market giving it a competitive edge.

Verizon and Charter: the Trump era heralds a wave of European-style cable–mobile consolidation - AnalysysMason Jan 207
"Seeing every Verizon move through the teleology of 5G misses the point; US mobile is shrinking and Verizon needs to spread its bets."

"In pursuing a mobile-first strategy, Verizon has progressively shrunk its wireline footprint. In the early part of last decade, the company was a proponent of FTTP, but found the capex burden intolerable, and of its 22% wireline coverage, only 15% has FiOS (FTTP) availability, with the rest on low-grade ADSL. Charter acquired the larger Time Warner Cable and the smaller Bright House Networks in 2015."

"Analysys Mason's view is that the USA is waking up to the same realities that hit Europe a few years ago: a mobile-first strategy no longer makes any 'industrial' sense, and the survival of mobile-only operators into the 5G era is in question. Market structure (with a geographical fragmentation of fixed but not mobile) has shielded the USA from this, as it has in other markets with a similar asymmetric structure such as Finland and Russia. While 5G-readiness is something to aspire to, the rationale for any merger is, from Verizon's point of view, much more immediate and banal: mobile revenue will come under increasing pressure; broadband/video has more growth potential than mobile; and fixed–wireless may not work."

"Analysys Mason forecasts rises in consumer wireline revenue and a decline in mobile revenue between now and 2021 in the USA."

"We believe that Verizon's interest in cable is at least in part motivated by the realisation that mmWave fixed–wireless (pre-standards 5G) is not the best way to address the great indoors."

CTIA, CCA blast FCC for slipping cybersecurity rule into 5G order | FierceWireless - Dec 2016
"Both CTIA and the Competitive Carriers Association (CCA), which don’t always see eye-to-eye on wireless regulatory issues, agree on one thing: The FCC’s proposal to require millimeter wave (mmWave) licensees to disclose network security plans is a bad idea.

Actually, both organization say it violates the Administrative Procedure Act (APA) because the FCC did not propose the rule in its original Notice of Proposed Rulemaking (NPRM), where entities like CTIA and CCA could have voiced their objections. Instead, they say the commission barely mentioned a security obligation in a “fact sheet” that was published less than a month before the order was adopted."

The Mobile Network » 5G needs verticals, so where are they? - Oct 2016
Via Dale Hatrfield

"much of the early technical selection has in fact been done: it’s going to be a variant of filtered OFDM, a flexible frame structure, coding is nearly done, MIMO will be not quite so massive after all, we know the likely spectrum bands."

"And one or two verticals did show in Frankfurt this week – notably the major German car companies BWM, Audi and also Continental. . . . But there was nobody, not one vertically-blessed ambassador from agriculture, health, energy, utilities, transport, smart City government or even public safety"

"Johan Wybergh ... Group CTO of Vodafone said that the industry must not over hype 5G. He pointed out that although mmWave offers very large frequency bands and high throughputs, it’s not good at going through walls into the places where people live"

FCC plan for 5G spectrum above 24 GHz branded too timid - PolicyTracker Oct 2015
"Federal Communications Commission (FCC) plans to make spectrum above 24 GHz available for 5G prompted strong criticism from Republican commissioners and a former FCC official who say the regulator hasn't gone far enough. The satellite industry urged the regulator to protect its services in the bands, while the wireless sector called for more low-band spectrum."

RSPG says light licensing could be a solution for 5G backhaul - PolicyTracker Jul 2015
"A new report by the Radio Spectrum Policy Group (RSPG), the inter-governmental group that advises the European Commission on spectrum matters, has identified light licensing as an “attractive” way of addressing growing demand for spectrum through wireless backhaul." Wireless backhaul users looking at 60 GHz and 70/80 GHz - but 5G also eyeing it. - "In these bands, the report argues that “light licensing or technology-neutral block licensing seem to be attractive alternatives to cope with the very high number of short links, compared to other approaches such as individual licensing, as they provide flexibility”. Licence-exemption is also identified as a “tempting option” but the report warns that this may result in unpredictable interference."

"Researchers at NYU Wireless, a research center of the New York University's Polytechnic School of Engineering, report promising findings that could enable 5G millimeter-wave (mm-wave) cells to be as large as several hundred meters, the same size as 4G cells in dense urban environments. The research, presented in Microwave Journal, indicates that mm-wave frequencies (30 to 300 GHz) show great promise for the future of wireless because of the large raw available, unused bandwidth."

Should European legislation be changed to accommodate small cell backhaul at 60 GHz? - PolicyTracker Jul 2014
Claim by Mark Barrett of Blu Wireless that inflexible European rules compared to US rules are impairing deployment of mm-wave solutions "he problem is that in Europe, as set out in CEPT Recommendation (09)01 and ETSI EN 302 217, maximum conducted power is limited to +10dBm and the minimum antenna gain is +30dBi. This does not allow any trade off in antenna gain and power. The US rule on this, as set out in FCC regulation 15.255, is much more permissive, Barrett says. Following a ruling in August 2013, devices can use the band indoors up to +40dBmi, and as much as +82dBmi in outdoor conditions, depending on antenna gain. "

Brown says that “mmWaves are not the silver bullet answer to 5G”. ... O'Brien: “The Koreans would like to see this occur earlier, tied to big national events. They are holding the Winter Olympics in 2018 ...” “My guess is the earliest would be Release 15. I used to say Release 16 because I think that's the right time frame if you back up everything in place”.

Research suggests millimetre waves could be used for 5G - PolicyTracker May 2014
"Researchers from New York University (NYU) said at the Brooklyn 5G Summit that spectrum in the millimetre wave bands is usable for 5G. The spectrum, which starts at 30 GHz and ends at 300 GHz, has previously been thought of as unusable because its signal attenuates so quickly and can only follow the line of sight. Nevertheless, according to many presentations at the conference, the band could provide at least some of the spectrum that will allow 5G to develop."

Ofcom | Review of the Spectrum Management Approach in the 71-76 GHz and 81-86 GHz bands - aug 2013
"This consultation proposes changes to the management and authorisation approach within the 71 - 76 GHz and 81 - 86 GHz (70 / 80GHz) bands. The 70/80 GHz spectrum has been used in the UK for Fixed Service applications since 2007 and offers access to 2 x 4.75 GHz of bandwidth and the ability to deploy fixed link applications with very high capacity capabilities that are not supported in the lower microwave bands (e.g. 1 Gbit/s and above). " "At present a self coordinated licensing approach is used to authorise use in these bands ...Under the self coordinated licensing approach licensees have responsibility to coordinate new links with existing deployments in the band. However, the Spectrum Review, completed last year, identified that there was a perception among some stakeholders that the current self coordinated approach at 70 / 80 GHz does not offer the certainty that is required for the high availability (99.99% - 99.999%) applications"

FCC boosts power limit for outdoor unlicensed 60 GHz links « Steven J. Crowley, P.E. Aug 2013
via Steven Crowley "The FCC has adopted a Report and Order that raises the power limit for outdoor links operating in the 57-64 GHz band on an unlicensed basis. The average equivalent isotropically radiated power (EIRP) limit is raised from 40 dBm (10 watts) to a maximum of 82 dBm (158,489 watts) depending on how high the antenna gain is. The peak power limit is 3 dB higher. The new power limit is comparable to others the FCC has in the fixed microwave services.This increase is expected to enable higher-capacity outdoor links extending to about one mile. Connection of buildings on a campus is one application, as is connections of small cells within a 4G macrocell. In addition to higher power limits, the FCC also changed the way 60 GHz emissions are specified for consistency with other rules, and it eliminated the need for certain 60 GHz devices to transmit an identifier."

Millimeter Waves May Be the Future of 5G Phones - IEEE Spectrum June 2013
"Samsung’s millimeter-wave transceiver technology could enable ultrafast mobile broadband by 2020" "By dynamically varying the signal phase at each antenna, this transceiver generates a beam just 10 degrees wide that it can switch rapidly in any direction, as if it were a hyperactive searchlight." "In outdoor experiments near Samsung’s Advanced Communications Lab, in Suwon, South Korea, a prototype transmitter was able to send data at more than 1 Gb/s to two receivers moving up to 8 kilometers per hour—about the speed of a fast jog. Using transmission power “no higher than currently used in 4G base stations,” the devices were able to connect up to 2 km away when in sight of one another, says Wonil Roh, who heads the Suwon lab. For non-line-of-sight connections, the range shrank to about 200 to 300 meters."
