Wi-Fi offloading would help relieve LTE networks and add value for consumers, Iain Gillott, founder of iGR, said in a webinar Thursday about Wi-Fi offloading. The webinar was sponsored by iGR, a market strategy consultancy focused on the wireless and mobile communications industry. Wireless companies such as AT&T have set up Wi-Fi hot spots in congested metropolitan areas as a way to ease the network traffic, and Gillott said those hot spots can be helpful, but in metro areas like New York City they're not the most effective. Other weaknesses for using Wi-Fi offloading are that older networks lack security and others have cumbersome log-ins, he said. There's also no handoff between Wi-Fi and 3G or 4G, Gillott said, and Wi-Fi roaming isn't as seamless as cellular. Despite those downsides to wireless companies offering Wi-Fi offloading for its customers, some strengths may be hard for those companies to ignore, he said. The network gets larger when the wireless companies have Wi-Fi hot spots everywhere, which can help with marketing, Gillott said. Wi-Fi offloading is also inexpensive to deploy and supports stationary traffic, he said. A big plus for consumers and wireless providers alike is that the free Wi-Fi usage helps customers stay under their data limits, Gillott said.

Just over two months since RadioShack’s Feb. 5 bankruptcy filing triggered Sprint’s store acquisition deal with RadioShack's largest shareholder Standard General and its General Wireless subsidiary (see 1502060023), Sprint set Friday as the grand opening of 1,435 “Sprint-RadioShack” stores within RadioShack stores, Sprint said in a Thursday announcement. The openings will more than double Sprint’s company-owned “retail footprint” from its current 1,100-store base, it said. The openings follow recent statements by Sprint senior management that the company was in crying need of more retail storefronts to raise its brand's public profile. Besides having a “great network” and a “compelling offer,” giving consumers more places to shop is one of the “basic fundamental principles” guiding a carrier like Sprint, CEO Marcelo Claure said on a recent earnings call. Before Sprint’s RadioShack store acquisitions, the company had 500-600 fewer retail locations than T-Mobile and 3,000 fewer than Verizon, he said. Sprint has said its ambitions are to “effectively operate a store within a RadioShack store” at the 1,750 RadioShack locations it’s acquiring. Sprint will occupy about a third of the retail floor space in each location, it has said. The stores will be co-branded, with Sprint being the primary brand on storefronts and in marketing materials, it has said. With Friday’s opening, Sprint hopes to begin to “transform the customer store experience” as it works to finish converting the remaining 315 RadioShack stores “over the next several months,” Sprint said.

The 7th U.S. Circuit Court of Appeals in Chicago upheld a lower court’s dismissal of a class-action lawsuit against the four major national wireless carriers alleging they colluded to fix prices for text messaging services. The case is Aircraft Check Services Co. et al. v. Verizon Wireless et al. “It is of course difficult to prove illegal collusion without witnesses to an agreement” and there are none in this case, Judge Richard Posner wrote for the panel that heard the case. It is also reasonable to expect that competing firms will closely track the pricing and other market behavior of their competitors, he said Thursday. “The plaintiffs have presented circumstantial evidence consistent with an inference of collusion, but that evidence is equally consistent with independent parallel behavior,” Posner wrote. Lawyers need to be careful about invoking the term collusion without being precise, he said. “Tacit collusion, also known as conscious parallelism, does not violate section 1 of the Sherman Act,” he said. “Collusion is illegal only when based on agreement. Agreement can be proved by circumstantial evidence, and the plaintiffs were permitted to conduct and did conduct full pretrial discovery of such evidence. Yet their search failed to find sufficient evidence of express collusion to make a prima facie case.”

Mitsubishi Electric is demonstrating with Nokia Networks a prototype Active Phased Array Antenna (APAA) to verify new multibeamforming technology for envisioned 5G mobile networks, at the Brooklyn 5G Summit in New York this week. Features of the APAA prototype include four-beam spatial multiplexing achieved in a multi-element antenna, beamforming control of the direction of radio signal transmission and reception for two-dimensional vertical and horizontal scanning and use of 3.5 GHz, the highest frequency available in current cellular mobile communication, Mitsubishi said. Mobile systems based on 5G will use multibeamforming to cope with fast-increasing radio traffic volume, it said. Mitsubishi plans to adapt its APAA technology, currently used commercially in satellites, for use in 5G base stations, it said.

The FCC gave final approval to several hundred licenses purchased in the AWS-3 auction, including many bought by AT&T, Verizon and T-Mobile. “Thanks to the FCC license grants today for AWS-3 spectrum, T-Mobile now has additional bandwidth in key markets that will strengthen our data network even more for our customers,” said T-Mobile Senior Vice President Andy Levin in an emailed statement Wednesday. Levin said T-Mobile’s focus is now on the TV incentive auction: “Now we are on to the next challenge — winning low-band spectrum in the auction next year. That will improve our service to customers everywhere, whether they are deep inside an urban office building or alongside a road in rural America. The next auction will make or break the future of wireless choice.”

Sony will invest about $374 million in Sony Semiconductor technology centers in Nagasaki and Yamagata, Japan, to boost monthly production capacity of stacked CMOS image sensors for smartphones and tablets by 45 percent to 87,000 by September 2016, the company said in a Tuesday news release. “Stacked CMOS image sensors deliver superior image quality and advanced functionality in a compact size,” Sony said. “Demand for these image sensors is anticipated to further increase, particularly within the expanding market for mobile devices such as smartphones and tablets.”

The FCC Public Safety Bureau said it's updating the FCC’s Public Safety Answering Point Text-to-911 Readiness and Certification Registry. The notice is intended to warn wireless carriers and other providers of interconnected text messaging services “of the effective readiness date of those PSAPs for which the Bureau has received the updated information,” the Tuesday notice said. “Also, the Bureau reminds covered text providers that they should periodically review the text-readiness of PSAPs in their service areas and reach out to these PSAPs as necessary to coordinate implementation of text-to-911 service.” Covered text providers must start routing 911 text messages to requesting PSAPs within six months, the bureau said.

FiberTower could come back from near death as a result of a decision last week by the U.S. Court of Appeals for the D.C. Circuit, said broadcast lawyer Harry Cole of Fletcher Heald in a blog post. The court last week vacated an FCC order canceling 42 of 689 licenses held by the wireless backhaul company, but told the FCC to revisit a request for an extension on the build out requirements of the other licenses as well (see 1504030042). “If you took the long odds and bet against the FCC in FiberTower’s last gasp effort to keep its 689 licenses alive, lucky you!” Cole wrote. “FiberTower’s 689 licenses appear to live on. The likelihood that the FCC will eventually relent and leave them all in place is impossible to gauge at this point, but at least FiberTower’s prospects are better now than they were before the Court’s opinion.”

FirstNet is providing additional time for comments on proposed interpretations of how it should operate under the spectrum law, which created it. Comments had been due April 13 (see 1503130064). The new deadline is April 28, said a notice published Tuesday in the Federal Register. This the second time FirstNet has asked for such comments. "This extension responds to numerous inquiries from interested parties that have requested additional time to respond based on the significant nature of the Second Notice," FirstNet said.

Sennheiser representatives met with Julius Knapp, chief of the FCC Office of Engineering and Technology, and other officials to say wireless mics "and white space devices use different technology and serve different purposes,” said an ex parte filing at the commission. “They should not be regulated identically.” Sennheiser showed its “top-of-the-line Digital 9000 wireless microphone system, demonstrating the technological innovations of the industry and showing how professional wireless microphone operators scan the UHF frequency range and take other steps to find clear spectrum for wireless microphone use,” the company said. The filing was posted by Tuesday in docket 12-268.
