\tAT&T VP of converged access and device technology Gordon Mansfield argued rivals may have jumped the gun on standalone (SA) 5G, noting a key technology had yet to be incorporated into consumer devices.<\/p>\n

Mansfield told Mobile World Live the operator began limited SA deployments [1] in late 2020 and was aiming to scale those to a consumer offering \u201clater this year\u201d, but was waiting for SA 5G carrier aggregation to reach handsets and tablets.<\/p>\n

Without aggregation, Mansfield said operators can only use one spectrum channel to deliver connectivity rather than combining several, severely limiting their ability to deliver a performance lift from 4G or non-standalone 5G.<\/p>\n

Mansfield argued \u201csome competitors have maybe prematurely gone to standalone\u201d, adding it \u201cis the path you need to get to to truly evolve from a consumer experience perspective, but you have to be smart about when you evolve to make sure that you\u2019re not taking steps backwards to then take steps forward\u201d.<\/p>\n

Rival T-Mobile US launched [2] nationwide SA 5G in August 2020 using its low-band 600MHz spectrum. In October 2020 it announced it completed an SA 5G carrier aggregation test on 600MHz and 2.5GHz spectrum.<\/p>\n

Mansfield said AT&T is working with vendors to test SA carrier aggregation-enabled silicon and believes it has \u201cline of sight\u201d to availability.<\/p>\n

From there, he noted the silicon will need to be incorporated into consumer devices, after which AT&T will conduct end-to-end validation testing on its network.<\/p>\n
