Using the correct antennas is a key part of helping providers cut their energy use, Andrzej Mikolajczuk, sustainability program director at Ericsson, blogged Tuesday. “Passive antennas are like tires on a car,” Mikolajczuk wrote: “You can have an impressive car with a massive engine, but if the car has bad tires, a lot of energy gets wasted. The same applies to antennas. If more of the propagation of the electromagnetic field is going in the desired direction, then the radio power can be reduced by up to 29%.” With improved antennas, handsets on the network also use less energy, he said. Updated antennas themselves are also more energy efficient, with a lighter structure and 100% recyclable radome, the weatherproof enclosure that protects an antenna, he said. “With the significant rise in connectivity demand, responsible resource management and environmental action are more urgent than ever,” he said. “Mobile network operators are key to keeping the world connected, but their operations often come with high energy costs and a sizable environmental footprint.”

Wi-Fi has been a huge win, offering broadband access in many locations, with more than 18 billion Wi-Fi devices in use and its success based on a “foundation in permissionless innovation,” the Competitive Enterprise Institute said in a report Tuesday. The U.S. approach contrasts with China's, where Wi-Fi is seen as a “threat,” CEI said. “Wi-Fi shows that when America embraces permissionless innovation it creates competitive advantages.” The report quotes inventor Nikola Tesla saying “when wireless is fully applied, the Earth will be converted into a huge brain, capable of response in every one of its parts.” CEI noted that people consume up to 80% of data indoors and Wi-Fi is largely used for indoor broadband. “Permissionless innovation is optimistic,” the report said: “It embraces human innovation and ingenuity as overall good things. It allows that harms from innovation can be addressed as they occur. Government need not attempt to anticipate or attempt to prevent potential harms, in large part because it is rarely possible to accurately predict what will go wrong and head that off at the pass.”

An AT&T representative met with an aide to Commissioner FCC Geoffrey Starks to oppose a handset unlocking mandate as proposed in a July NPRM (see 2407180037). “This proposal is based on questionable legal authority,” the carrier said in docket 24-186: “AT&T offers an array of affordable options for handsets, including subsidized pricing and zero-interest rate financing” and “handset locking facilitates the offering of such options.” The company previously met with aides to Chairwoman Jessica Rosenworcel and Commissioners Brendan Carr and Anna Gomez raising similar concerns (see 2411130008).

T-Mobile plans on using the Formula 1 Las Vegas Grand Prix this weekend as a 5G showcase. “Fans tuning into the race will enjoy first-person trackside and sweeping aerial views of the race and Las Vegas thanks to new 5G-connected cameras and a 5G-connected drone,” T-Mobile said Monday. Fans can also watch instant replays “so they don’t miss a second of the action.” The carrier is using 5G slicing “to enhance event operations by powering all point-of-sale and ticketing transactions so fans can seamlessly get into the event and make purchases without delay.”

T-Mobile should discontinue or modify an ad promising a free iPhone and 20% savings on monthly service “to better disclose the material conditions of the offer,” the Better Business Bureau's National Advertising Division ruled Monday. NAD responded to a complaint from AT&T. T-Mobile plans to appeal the decision. The commercial “features Twitch influencer Kai Cenat, NFL player Patrick Mahomes, and Snoop Dogg, who says, ‘Now at T-Mobile.com get the new iPhone 16 Pro ON US and families can save 20% every month versus the other big guys,’” NAD said: “The details of the free iPhone offer appear onscreen briefly before being replaced by an image of the 20% savings claim.”

Spectrum for the Future Monday welcomed a NTIA report about usage growth in the citizens broadband radio service band (see 2411150021). The group said the report shows why the FCC shouldn't increase power levels available in the band (see 2411080032). “While some have suggested raising power levels or out of band emissions limits, that path would only jeopardize our ability to deliver greater innovation, wider-ranging use cases, and more consumer choice,” a spokesperson emailed: “The data shows that dynamic spectrum sharing is working, and we should maintain the unique properties that make CBRS the model for U.S. wireless leadership.”

Brattle Group officials and others representing NextNav met with an aide to FCC Commissioner Anna Gomez on NextNav’s plan to reconfigure the 902-928 MHz band to enable a terrestrial complement to GPS for positioning, navigation and timing (PNT) services (see 2404160043). The Brattle representatives discussed their assessment of the potential economic benefits, said a filing posted Monday in docket 24-240. They “explained the conservative valuation methodology they employed in preparing their analysis, and they reviewed both the economically quantifiable benefits NextNav’s proposal would generate, which figured into their valuation estimate, and the potential for significant benefit in terms of lives saved, which did not,” the filing said.

NTIA told the FCC that utilization of the citizens broadband radio service band is up sharply and the three-tier shared band has been a success. “With CBRS, the Commission established a ground-breaking spectrum-sharing paradigm that has enabled commercial access to mid-band spectrum and has evolved to demonstrate the success of a collaborative partnership among stakeholders in the public and private sectors,” said a filing posted Friday in docket 17-258. CBRS deployments increased 270,621 from April 1, 2021, to July 1 this year, the filing said. Rural CBRS devices (CBSDs) “more than doubled, with an increase of 166,650 (160.6%)" and "67.5% of all CBSDs were in rural census blocks,” NTIA said. It found that 82.7% of all U.S. counties used at least one CBRS channel and 41% used all 15 as of July 1.

The FCC Wireless and Public Safety bureaus on Friday updated the 4.9 GHz band licensing freeze, consistent with an order commissioners approved last month (see 2410220027). The changes take effect immediately, the bureaus said. They added to the list of affected applications “applications filed by incumbent 4.9 GHz licensees to modify existing licenses in the 4.9 GHz band, whether for permanent fixed sites or geographic areas” and “applications filed by incumbent 4.9 GHz licensees for new permanent fixed site operations located within their licensed service areas.” A critic of the order noted last week that the FCC expanded the freeze in a way that was likely not well understood by public safety agencies when it was handed down (see 2411130027). The bureaus said the FCC would continue accepting some applications, including to renew existing licenses without modification or seeking to modify existing licenses by deleting frequencies or fixed sites.

Tech companies' recent filing (see 2411070023) countering a broadcaster study on interference to electronic news-gathering (ENG) operations from very-low-power (VLP) devices in parts of the 6 GHz band doesn’t oppose an ENG “safe harbor,” NAB noted in a filing at the FCC. Broadcasters have asked that the agency “temporarily reserve a small fraction of the 6 GHz band -- the 55 MHz band at the top of the U-NII-8 sub-band … as a ‘safety valve’ in the event of interference,” said a filing Thursday in docket 18-295. “The claim that the ‘vast majority of VLP devices will not operate in locations where they could cause harmful interference’ is specious,” NAB added: “The whole point of the VLP service is that the devices can be used anywhere and need not be under the control of an access point.”
