AT&T Details 5G Evolution
















5G Evolution, AT&T Fiber, and Trials Advance Network Built for Video and Data
AT&T* today announced its 5G Evolution plans for 2017 and beyond, and highlighted its other initiatives to expand and enhance ultra-fast internet access for millions of customers.
“Our 5G Evolution plans will pave the way to the next-generation of higher speeds for customers. We’re not waiting until the final standards are set to lay the foundation for our evolution to 5G. We’re executing now,” said John Donovan, chief strategy officer and group president, Technology and Operations.  “Data on our mobile network has increased about 250,000% since 2007, and the majority of that traffic is video. 5G’s promise of greater speed and overall network performance brings huge opportunities not only for video but in the Internet of Things, 4K video, augmented and virtual reality, smart home and cities, autonomous vehicles and much more.”
Our 5G Evolution
The path to 5G encompasses fixed and mobile solutions. We continue to collaborate with more than a dozen global technology companies around 5G standards efforts, and our initial lab trials are already achieving speeds up to 14 gigabits-per-second (Gbps) over a wireless connection.
In lab trials, we’ve successfully tested a connection with less than 3 milliseconds of latency, which surpasses any current LTE network technology. Latency impacts things like the time between pressing play and seeing a video start to stream or between hitting a web link and seeing a webpage begin to load. The industry expectation for 5G is latency less than 5 milliseconds.
Here’s additional color around our 5G Evolution:
AT&T Fiber Update
Today, we’re marketing a 1 gigabit connection** on our 100% fiber network to nearly 4 million locations across 46 metros nationwide. More than 650,000 of these locations include apartments and condo units. We have the largest fiber network across the 21 states where we offer home internet service and by mid-2019 we plan to reach at least 12.5 million locations across 67 metro areas with our 100% fiber network.
We are also conducting technology trials over fixed wireless point-to-point mmWave and G.fast technologies to deliver greater speeds and efficiencies within our copper and fiber networks.
Rural Broadband Efforts
There are still many homes in the U.S. – especially in rural areas – that have slow or no internet connectivity. In 2016, we began trialing Fixed Wireless Internet (FWI) service in several states. We plan to begin offering FWI in mid-2017 in areas where we accepted FCC Connect America Fund Phase II (CAF II) support. We expect to reach more than 400,000 locations by the end of 2017 across the 18 states where we accepted CAF II funds, most of which will get internet access for the first time. By the end of 2020, we plan to reach 1.1 million locations in those 18 states.
Project AirGig Progressing
In September 2016, we unveiled Project AirGig, a transformative technology from AT&T Labs that could one day deliver low-cost, multi-gigabit wireless internet speeds over power lines.
Project AirGig is one of the most ambitious and inventive projects in AT&T Labs history. We now have more than 200 patents and patent applications for Project AirGig and we plan to begin field trials in 2017.
Project AirGig has the potential to be a win for our customers and a win for the electric utility companies. Collaborations between AT&T and utility companies could enable and expand a variety of smart-grid applications such as early detection of line integrity issues and help with proactive line maintenance.
*AT&T products and services are provided or offered by subsidiaries and affiliates of AT&T Inc. under the AT&T brand and not by AT&T Inc.
** Actual customer speeds may vary. Download speeds are typically up to 940Mbps due to overhead capacity reserved to deliver the data.
