    AT&Tís Fuetsch says company is still testing standalone 5G

    https://www.fiercewireless.com/wirel...-standalone-5g

    AT&T is still in the testing phase of standalone 5G and is not saying when it will deploy the technology. Speaking today at the Brooklyn 6G Summit, a virtual event hosted by NYU Wireless, Nokia and iEEE, Andre Fuetsch, EVP and CTO of AT&T Services, said that the operator is currently testing its standalone 5G (5G SA) core that will enable cloud-native functions and network slicing. However, he didnít provide an additional information about when it would actually launch 5G SA.

    This is a bit of a departure for the operator, which in September 2020 said that it was testing its 5G SA core and planned to fully deploy it in 2020.

    AT&T has been the most vocal U.S. wireless operator when it comes to talking about the virtualization of its core network. The company announced in September 2020 that it had reached its goal of virtualizing 75% of its network functions.

    Competitor T-Mobile so far is the only U.S. operator to deploy 5G SA, The company announced back in August 2020 that it had deployed 5G SA on its 600 MHz spectrum and it was available nationwide.

    During his speech, Fuetsch also highlight the companyís C-Band 5G buildout, which he said will provide a ďgood balance of coverage and capacity.Ē He said that AT&T expects to cover 70 million to 75 million people with its 5G C-Band network by the end of 2022 and cover more than 100 million by the end of 2023.

    And although this event is called the Brooklyn 6G Summit, most of Fuetschís comments were focused more on 5G and the evolution of that technology. Specifically, he mentioned the companyís 5G Innovation Studio where AT&T is working with other companies and customers to develop 5G applications and use cases. The goal of the Innovation Studio is to help bring products to market faster and provide a space where customers can explore and try out tech using advanced network capabilities.

    One example Fuetsch provided was AT&Tís work with Microsoft Azure on autonomous drone control with Israeli startup Vorpal. Using edge computing, Vorpal is able to track thousands of drones to help prevent air accidents and keep drones from creating safety issues with commercial airlines.

    As far as the future, Fuetsch said he believes we will see a ďparadigm shift from 5G to the next GĒ and that the next G will need to have an open network architecture. He added that disaggregation of the network will be vital in a 5G world and touted AT&Tís work with Open RAN. He also said that edge computing will create new opportunities for smart cities and smart industrial uses because the increased network speeds and reduced latency will be transformational.

    So, does anybody think that AT&T’s C-band will come online in December using NSA, or will they wait until SA is ready in TBD 2022?

    There are a lot of test sites in different cities that are already online with both SA and NSA but not available to consumer UE currently. They are probably waiting for the green light to turn it up commercially and to start rolling firmware updates to enable it on supported devices. The non test sites getting C band upgrades should be ready when the FCC gives the go ahead. Hopefully, December or sooner.

    Unless there's a ton of spectrum deployed, 5g SA won't help that much, similarly unless it's on Most sites. Lowband SA deployment can be useful, es6in rural areas. Midband isn't great on upload on SA, as handsets are weak for high rf upload. NSA midband with lower band lte (for upload aggregation) makes a world of difference. 5g SA N41 + 20MHz AWS will give +700Mbps download and 140Mbps upload. Move behind a wall, and download doesn't change much, but upload drops to about 60Mbps. C band will probably be similar.
