AT&T and the City of Los Angeles are unveiling ShakeAlertLA, a unique mobile app designed to alert residents in Los Angeles County of an earthquake.
Creating the network that will eventually link millions of quantum devices together requires tapping into the collective intelligence of numerous experts working and networking together.
AT&T is combining our edge-to-edge capabilities with blockchain technology to help companies transform the way they conduct business.
Blockchain is a cryptographic technology based on a mathematical structure for storing data in which groups of valid transactions, called blocks, form a chronological chain, with each block cryptographically linked to the previous one.
In December of 2018, AT&T became the first and only company in the U.S. to offer a mobile 5G device over a commercial, standards-based mobile 5G network.
In October 2018, we successfully completed the world’s first millimeter wave mobile 5G browsing session with a standards-based device on our mobile 5G network.
Mid-band spectrum ranges from 2.5 GHz to 6 GHz. This band has good propagation and the ability to have greater capacity – through spectrum reuse or wider channels – adding a critical complement to the existing mobile spectrum ecosystem to be an essential component of future 5G networks.
We’re moving closer to commercial deployment of AirGig every day and have initiated discussions with technology suppliers to start testing and building commercial-grade Project AirGig equipment.
5G will ultimately unlock use cases that are dependent on faster speed, wide coverage, and low latency. Think of this as the next frontier in untethering, giving you the ability to take the ultra-fast experience you have in your home or business with you virtually anywhere.
Until recently, mobile operators believed that 3 GHz was the upper limit of “usable” spectrum or frequencies for terrestrial mobile service necessary to provide commercial mobile broadband services. Today, however, new use cases, such as providing HD video to customers, along with technology advancements, have expanded the potential frequencies for terrestrial mobile broadband use – well into the millimeter wave bands or those bands above 24 GHz.
AT&T now has an agreement with Three Group to resell Three UK wireless services. The agreement will allow AT&T to offer its global business customers in the U.K. localized contracting and billing for wireless voice, data, and SMS services.
