Wireless Internet

It’s a question that has baffled many minds for years. The mismatch between the U.S. population growth rate and U.S. wireless carriers’ ability to add oodles of new phone customers every quarter has mystified some Wall Street analysts for eons. “Investors have been puzzling over the industry’s ‘excess growth’ for years now,” wrote Craig Moffett of MoffettNathanson Research. “Wireless is, after all, a fully saturated industry in the U.S.

It’s been a long time coming, but T-Mobile has found a buyer for the 800 MHz spectrum it inherited from Sprint.

Future G networks will require more dynamic, agile support for the management of radio spectrum on a fine-grained basis. The radio access network (RAN) technologies necessary to enable Dynamic Spectrum Access (DSA) have progressed significantly over the past 20 years, but the challenges of realizing the potential for DSA requires the co-evolution of technologies, business models, and regulatory policy. This paper presents a multidisciplinary research effort to develop the building blocks needed to advance DSA.

Verizon and T-Mobile are at it again, and this time, it’s more about what’s above their terrestrial networks than what’s on the ground. To be sure, these two have been at each other’s throats for years, primarily because Verizon made a reputation for itself as the carrier with the “best network” and T-Mobile, long known as a network laggard, set its sights on upending that.

T-Mobile has won a BBB National Programs’ National Advertising Division Fast-Track SWIFT challenge brought by Verizon, related to T-Mobile’s claim to be the “first and only” U.S. wireless provider to work with Starlink to provide satellite-powered text messaging. Fast-Track SWIFT challenges enable NAD to review single-issue advertising issues.  In this case, a statement, made at T-Mobile’s website and in a LinkedIn post, said that  “T-Mobile is the first and only U.S.

T-Mobile demonstrations using a commercial Samsung Galaxy S25 and a non-commercial mobile test device achieved a 6.3 Gbps “record-breaking” downlink speed in a recent trial. The Galaxy S25 test featured Qualcomm’s Snapdragon X80 5G Modem-RF System running text software on T-Mobile’s 5G network. It reached a download speed of 4.3 Gbps in real-world conditions. The second test featured Qualcomm’s X85 5G Modem-RF on a mobile test device.

The future of America’s broadband is at a crossroads. Commerce Secretary Lutnick recently stated that the Broadband Equity, Access, and Deployment (BEAD) program is in “dire need of a readjustment.” With his call for a “tech-neutral” approach, all signs point to a shift away from fiber and towards satellite.

There is an interesting trend of internet service providers selling broadband products that are not always guaranteed to be at the same speed and quality as other customers. I've especially noticed this practice in recent years from big fixed wireless providers that sell home broadband using cellular spectrum. AT&T, T-Mobile, and Verizon have all reserved the right to throttle customers any time that the network gets too busy. It’s easy to understand why cellular companies would throttle home broadband customer first—they are protecting their cellular customers.

The independent inquiry group appointed for this market investigation has found that a number of markets relating to browsers on mobile devices are not working well for consumers and businesses, which is holding back innovation and could be limiting growth in the UK. Mobile browsers are apps which provide the primary gateway for consumers to access the web on their mobile devices, and hence for businesses to reach them with their content and products.

Comcast has pushed ahead with a new mobile offering aimed at customers who take one of the operator's higher-end home broadband speed tiers. Comcast combined that announcement with a wave of free speed upgrades—including faster upstream speeds—across its prepaid and postpaid home broadband services. On the mobile end, Comcast is now offering new and existing home broadband customers an unlimited line of Xfinity mobile for a year when they subscribe to broadband speeds of 400 Mbit/s or faster.
