AT&T Details 5G Evolution
5G Evolution, AT&T Fiber, and Trials Advance Network Built for Video and Data
“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:
- 1 Gbps Speeds in 2017: The continued deployment of our 4G LTE-Advanced network remains essential to laying the foundation for our evolution to 5G. In fact, we expect to begin reaching peak theoretical speeds of up to 1 Gbps at some cell sites in 2017. We will continue to densify our wireless network this year through the deployment of small cells and the use of technologies like carrier aggregation, which increases peak data speeds. We’re currently deploying three-way carrier aggregation in select areas, and plan to introduce four-way carrier aggregation as well as LTE-License Assisted Access (LAA) this year.
- 5G Video Trial with DIRECTV NOW: In the first half of 2017, we plan to conduct a trial in Austin where residential customers can stream DIRECTV NOW video service over a fixed wireless 5G connection. As part of this trial, we’ll also test additional next-generation entertainment services over fixed 5G connections. The trial will include multiple sites and devices, and we expect to further advance our 5G learnings – especially in how fixed wireless mmWave technology handles heavy video traffic. And over time, the reach of our 5G deployments will be enhanced even more as customers discover new, innovative mobile-first video services.
- First 5G Business Customer Trial: Last fall, we launched what we believe to be the industry’s first 5G business customer trial in Austin with Intel and Ericsson using millimeter wave (mmWave) technology, which can deliver multi-gigabit speeds using an unlicensed band of spectrum. We trialed several video streaming and conferencing experiences, and saw upload and download speeds around 1 Gbps during the first phase of the trial.
- Additional 5G Trials: We recently announced plans to team up with Qualcomm Technologies and Ericsson for mobile and fixed wireless trials in the second half of 2017. These trials are significant because they will be our first trials to use what we expect to be based upon the 5G New Radio specification being developed by the industry technology standards group 3GPP. Industry standards are important to enabling wide-scale 5G commercialization. The trials will test both mobile and fixed wireless solutions operating in mmWave spectrum accelerating commercial deployments in the 28Ghz and 39Ghz bands. They will showcase new 5G radio mmWave technologies for increasing network capacity while achieving multi-gigabit data rates.
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.
- Millimeter Wave Trial Expansion: In October 2016, we announced our multi-dwelling unit (MDU) fixed wireless point-to-point mmWave trial in Minneapolis. This gives us the potential to reach a new customer base outside of our traditional 21 state wireline service area. We’re also exploring additional markets for trial locations.
- G.fast Experiments Expanding: G.fast technology enables us to bring the speed of fiber to existing copper lines that already exist in many locations. We’re encouraged by the results of our G.fast trial taking place at another MDU in the Minneapolis area. In fact, we're gearing up to offer G.fast to more locations, primarily MDUs, within our 21 state wireline footprint in 2017.
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.
