Registry and related records
- Editorial contextAT&T's Davis Wade network is neutral-host by design; the other hosts remain unnamed, AT&T is leading and will own a 53-sector MIMO distributed-antenna system at Mississippi State University's Davis Wade Stadium, using Airspan's MobileAccess 6000 platform across mid-band spectrum. The design is intended for more than 60,000 seats and multiple operators, but no other carrier, commissioning result or crowded-event performance measure has been disclosed.Medium confidence
- Editorial contextAT&T's 2017 VoLTE 911 outage made emergency-call routing changes an accountability test, For five hours on March 8, 2017, a mismatch between AT&T's provisioning record and its live emergency-call network prevented thousands of customers from reaching 911 directly. The Federal Communications Commission traced the event from an incorrect IP whitelist through Session Border Controllers, a shared reset response, an undersized manual fallback and a slow cross-team diagnosis. The lesson is narrower and more useful than saying that redundancy failed: records, change classification, path isolation, alarm delivery, fallback capacity and public-safety notification all have to be proved against the network that actually ran.Medium confidence
- Editorial contextFirstNet’s new 5G core moves public safety into a separate network decision room, A different 5G symbol on an emergency worker’s handset would say little about who controls the connection. FirstNet’s consequential change is deeper in the network: subscribers have begun moving to a nationwide standalone 5G core dedicated to public safety and physically separate from AT&T’s commercial core. That core decides how sessions are authenticated, policies applied and traffic handled; multiple geographically distributed sites are intended to keep those functions available when one location is impaired. The launch is an architectural milestone, not a completed performance result. AT&T has not disclosed migration coverage, site locations, failover tests, measured latency or upload gains, and compatible devices and plans are still required.Medium confidence
- Editorial contextAT&T's 1990 Long-Distance Outage Made Signaling-System Change Isolation an Accountability Test, A routine switch recovery became a national long-distance disruption because shared signaling software, coupled processor recovery and an insufficiently isolated fleet change allowed one timing-sensitive condition to reproduce across the network.Medium confidence
- Editorial contextAT&T owns EchoStar’s spectrum now; the buildout clock has started, AT&T has closed its approximately $23 billion purchase of EchoStar spectrum licences, adding about 30 MHz in the 3.45 GHz band and 20 MHz at 600 MHz across virtually every US market. The assets can widen coverage and capacity, but a licence transfer is not a network upgrade. The economic test begins with deployment, leverage and the FCC milestones now tied to the closing date.Medium confidence
- Editorial contextAT&T’s sub-15-second result proves one optimisation path, not quantum advantage, AT&T has signed an agreement to expand its work with D-Wave after one network-optimisation workload fell from about one hour to under 15 seconds. The initial focus is annealing inside tools that support agentic AI; outage, routing, build and traffic uses remain candidates to explore.Medium confidence
- Editorial contextAT&T’s million-add quarter was really three different network bets, AT&T added more than one million advanced-connectivity customers across fibre, fixed wireless and postpaid phones in the second quarter. The total is impressive, but the useful signal is the mix: the operator is using several access technologies to widen its addressable market while accelerating planned share repurchases.Medium confidence
- Editorial contextAT&T Made Wireless Continuity a Configuration-Accountability Test, AT&T Mobility's February 2024 outage shows how a production configuration error, failed peer review, missing safeguards, and overloaded registration systems turned a three-minute change into a twelve-hour recovery problem.Medium confidence
