AT&T’s plans for 5G are somewhat confusing at first glance, as the company talks about at least four current and upcoming 5G-related services. At the forefront are 5G Evolution and Mobile 5G, mobile services offering different connection speeds. AT&T also promotes LTE-LAA connectivity for 1Gbps downloads along with an upcoming in-home fixed wireless service.
Of the big three, AT&T’s puzzle pieces were harder to put together. In comparison, T-Mobile is more black-and-white, taking a simpler approach to its public 5G rollout plans. Simply put, T-Mobile is focusing on a long-range nationwide 5G service first followed by an in-home fixed wireless service at a later date. Its short-range service using millimeter waves will open shop in specific markets at the end of 2018 and into 2019 as devices hit the market. Full nationwide coverage isn’t expected to become available until 2020.
Meanwhile, Verizon is rolling out a 5G-based fixed in-home service first based on a proprietary 5G TF network standard. Customers now signing on are coined as “First on 5G” members and will see free equipment upgrades when models based on the 3rd Generation Partnership Project (3GPP) 5G NR standard arrive. Verizon also plans to launch a mobile 5G service six months after the full launch of its fixed in-home solution.
AT&T 5G Evolution
This isn’t AT&T’s real 5G network, instead serving as the foundation for the true AT&T 5G service that will arrive later. This platform only provides theoretical peak wireless speeds of up to 400Mbps for compatible devices. Think of it as an “evolving” 4.5G platform (or ramp) that will eventually give way to a full-blow AT&T 5G service.
According to AT&T, this 5G Evolution platform consists of upgraded cell towers and new small cell networks powered by LTE Advanced technology, such as three-way carrier aggregation, 4 x 4 MIMO antenna setups and 256-QAM modulation. The company is also using software-defined networking, artificial intelligence and more to increase data transmissions over the current 4G LTE speeds.
5G Evolution launched on April 25, 2017 in select areas of Austin, Texas. AT&T expanded this platform to more than 400 markets in 2018 and expects to provide nationwide coverage for more than 200 million customers in the first half of 2019.
Plans and prices
Because 5G Evolution is a back-end upgrade to AT&T’s 4G LTE service supported by newer phones, AT&T doesn’t provide new plans or pricing.
This is the true AT&T 5G service for mobile devices, based on the 3rd Generation Partnership Project (3GPP) 5G New Radio standard.
AT&T says it’s currently establishing small cell networks in mid-size and big cities to transmit AT&T 5G coverage “in pockets of dense areas.” Because millimeter waves can’t easily penetrate buildings and other obstacles, and are absorbed by plants and rain, AT&T is strategically placing these small cells throughout the cities to provide the best reception. These small cells can mount on streetlights, utility poles, and more.
Connecting the company’s wireless towers and small cells are “millions of miles” of fiber optic cables already feeding gigabit internet to more than nine million locations. AT&T is still expanding this wired network, shooting to reach 14 million locations by the middle of 2019.
For urban, suburban, and rural areas, AT&T says it will rely on its claimed mid- and low-band spectrum although the company doesn’t provide any specifics.
For now, the mobile AT&T 5G network primarily uses millimeter waves on the 39GHz band, but it will also shift small portions of its low-band spectrum to support its true 5G service. AT&T says more spectrum will be allocated from its 4G service to 5G as devices emerge and customer demand for 5G connectivity increases.
AT&T controls a combined 145 MHz of the sub-3GHz spectrum in North America. It also has access to a nationwide 20MHz block of the 700MHz spectrum held by FirstNet. Whatever is not currently in use by the Nationwide Public Safety Broadband Network can be utilized by AT&T when needed. Here are the claimed spectrums:
- 700MHz (BC and DE)
- 850MHz (Cellular)
- Personal Communications Service (PCS) in the 1,900 MHz range.
- Advanced Wireless Services (AWS) in the 1,700 MHz (uplink) and 2,100 MHz (downlink) ranges.
- Wireless Communication Services (WCS) in the 2,300 MHz range.
AT&T’s Mobile 5G service is currently available in Atlanta, Charlotte, Dallas, Houston, Indianapolis, Jacksonville, Louisville, New Orleans, Oklahoma City, Raleigh, San Antonio, and Waco.
By early 2019, Las Vegas, Los Angeles, Nashville, Orlando, San Diego, San Francisco, and San Jose will support AT&T’s true 5G connectivity as well. – Android Authority
