AT&T will be launching its 5G Evolution network across Minneapolis by the end of 2017, involving network upgrades in some areas of the city as well as distributed antenna system (DAS) upgrades at the city's stadium ahead of hosting the 2018 Super Bowl.
The network upgrades involve the addition of 4G LTE-Advanced features including 4x4 Multiple-Input Multiple-Output (4x4 MIMO), 3x carrier aggregation, and 256 Quadrature Amplitude Moderation (256 QAM).
Between 2014-16, AT&T said it invested almost $350 million in its Minnesota wireless and wired networks, making 1,271 wireless network upgrades in 272 communities in the city throughout 2016.
AT&T, which also rolled out an enterprise Internet of Things platform in September, has additionally installed small cells throughout Minneapolis, and is planning to add more over the next few months.
"We've been working closely with the city of Minneapolis to ensure its network is ready to support the technology of the future. The investments we're making prepare us for the future of 5G and innovations like smarter cities and immersive entertainment experiences like augmented and virtual reality," AT&T said.
"Besides upgrading the network in and around downtown Minneapolis ... we've overloaded the stadium with wireless capacity and boosted LTE capacity by more than 150 percent compared to last year. With more than 800 antennas, the network inside the stadium alone could provide coverage to the entire city of Minneapolis."
According to AT&T, its 5G Evolution network will be compatible with the LG V30, Moto Z2 Force Edition, Samsung Galaxy Note 8, Samsung Galaxy S8, Samsung Galaxy S8 Plus, and the Samsung Galaxy S8 Active handsets, with more to be compatible in future.
It is working with more than a dozen global tech companies on its deployments, with lab trials seeing speeds of 14Gbps for its fixed-wireless 5G technology. In August, it announced it would expand its 5G trials to three more cities by the end of 2017 in South Bend, Indiana; Waco, Texas; and Kalamazoo, Michigan.
For those three trial networks, AT&T is using Ericsson's 28GHz radios, virtualised RAN (vRAN), and full 5G virtualised core; Intel's 5G mobile trial platform; Samsung's 5G router, 5G RFIC chipset, virtualised core, and vRAN; and Nokia's 5G equipment and solutions.
AT&T launched its 5G Evolution upgrade on its network in Austin, Texas in June, followed by Indianapolis, Indiana in July.
According to AT&T, its small business and consumer trials in Austin have given it "new insights into millimetre-wave (mmWave) performance and propagation".
"In Austin, we see all types of weather and substantial foliage; taking our fixed-wireless 5G trials out of the lab and into the real world helps us learn important factors about mmWave and 5G," AT&T Wireless Network Architecture and Design senior vice president Marachel Knight said.
These trials have seen speeds of up to 1Gbps and latency of less than 10 milliseconds, AT&T said.
The network will be rolled out to 20 metro areas by the end of 2017, including Los Angeles, San Francisco, Boston, Chicago, Atlanta, and Nashville.
It is also aiming to deploy LTE-Licence Assisted Access (LTE-LAA) and 4x carrier aggregation on its 4G network by the end of the year, through which it attained speeds of 750Mbps during a trial in San Francisco.
AT&T is also using fixed-wireless deployments to improve access to broadband across regional areas of the United States under a partnership with NetComm Wireless.
NetComm Wireless, which also supplies fixed-wireless equipment to Australia's National Broadband Network (NBN), is providing AT&T with outdoor wireless antennas enabling connectivity speeds of at least 10Mbps to under-served premises across 18 states.
AT&T and NetComm Wireless have already deployed their first phase of fixed-wireless throughout the states of Louisiana, Florida, Alabama, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee.
While AT&T's plans for 5G have seen it "aggressively deploying equipment" as well as investing in spectrum and technology, it was outbid in May by rival operator Verizon, which acquired Straight Path Communications and its portfolio of mmWave spectrum licences for $3.1 billion -- almost double AT&T's original $1.6 billion bid.
Verizon last month announced that it is accelerating its 5G New Radio trials with a goal of launching its next-gen network by 2019.
In June, Verizon told ZDNet that one of the "key" parts of 5G is interoperability, with the carrier working not only with Qualcomm and Ericsson but also with Cisco, Samsung, Intel, LG, and Nokia to roll out its pre-commercial 5G trial networks across the US.
Verizon senior solutions architect Chris Painter confirmed to ZDNet that Verizon's remaining 10 pre-commercial 5G trial networks -- in Atlanta, Georgia; Dallas and Houston, Texas; Miami, Florida; Sacramento, California; Seattle, Washington; Washington DC; Bernardsville, New Jersey; Brockton, Massachusetts; and Denver, Colorado -- will be deployed before the end of 2017.
Verizon also trialled 5G during the Indianapolis 500 motor race in partnership with Intel and Ericsson in May, using technologies such as beam forming and beam tracking to attain speeds in excess of 6Gbps.
Deutsche Telekom has said its 5G trial network in Berlin puts it ahead of Europe in implementing the new mobile networking standard, with the telco working with Intel, Huawei, Ericsson, and Nokia on trials and use cases.
