T-Cell Places Velocity on the High of its Standalone 5G Targets

T-Cell is as soon as once more forward of the pack in the case of pure standalone 5G in the US.

Following its 600MHz nationwide 5G community launch in August 2020, T-Cell has now transformed its 2.5GHz mid-band community—which the corporate markets as “ultra-capacity”—to run on a 5G core. T-Cell stated that this community, which launched in November 2022, covers greater than 250 million folks within the U.S., and places the service forward on standalone 5G within the U.S. 

In the meantime, carriers worldwide are simply beginning to transfer to standalone 5G. The third Era Partnership Challenge (3GPP) accomplished its preliminary standalone 5G specification in September 2018. But AT&T, Verizon and most different main cellular community operators (MNOs) worldwide nonetheless depend on a non-standalone (NSA) 5G community for his or her industrial 5G providers.

Verizon has solely just lately began to maneuver industrial visitors onto its 5G standalone core. AT&T says it’s transferring clients in the direction of standalone 5G in phases. Each operators use an NSA 5G radio community related to a 4G core community for a lot of their 5G service.

Up to now, an NSA was the one method to deploy a 5G community when the usual first began to roll out in 2019 and 2020. An NSA 5G community can be cheaper to deploy because it makes use of an present 4G core.

A number of the finest advantages of 5G, nonetheless, are solely out there when a community is only 5G.

“Standalone 5G requires software program updates within the Radio Entry Community and a 5G Core Community, in addition to a adequate quantity of spectrum devoted to 5G and community optimization,” a T-Cell spokesperson stated in an electronic mail reply to EE Instances’ questions.

T-Cell is beginning its mid-band standalone journey by bringing service aggregation to its community, which includes assigning a number of radio channels to a consumer on the 5G service. These frequency blocks are often known as service channels.  

“We’re leveraging 5G service aggregation on our standalone 5G community,” the T-Cell spokesperson stated. “At present, we’re aggregating two channels of two.5 GHz in locations, in addition to 2.5 GHz + 600 MHz.” The MNO has additionally began to mix two or extra separate channels of two.5GHz with a tranche of 1900MHz spectrum.

The intention of that is to extend 5G obtain speeds for customers. T-Cell stated that speeds will range, relying on the frequency blocks used. The service famous, nonetheless, that in latest three-band checks, the aggregation has produced peak speeds topping 3 Gbps. 

Pure 5G crucial to community slicing

One of many major benefits that standalone 5G permits past NSA is community slicing, which permits an MNO to create digital end-to-end sections on a bodily community that may have service degree agreements and different traits that cater to a selected subscriber base. 

Since 5G first got here into industrial use, distributors and operators have been crowing about the advantages of community slicing. The know-how, nonetheless, can’t be delivered with out a pure 5G standalone community.  

“We’re nonetheless within the early phases of 5G community slicing implementation,” the T-Cell spokesperson stated, including that community slicing “expands the marketplace for crucial enterprise purposes that will require a unique degree or functionality than different purposes, resembling distant operations, robotics and automation.”

MNOs stay cautious about standalone objectives

Whereas T-Cell has a head begin on getting its standalone networks up and working, Verizon stated that in October 2022 it began transferring visitors onto its standalone core following testing and pleasant trials. The corporate hasn’t given any additional particulars about what number of customers are lined by its standalone community. 

AT&T can be cautious about giving an excessive amount of away about its standalone plans. “AT&T continues to make progress with our standalone 5G industrial launch,” the corporate stated in ready remarks. “We have now begun to steadily migrate customers to the core in phases all through 2022 and into 2023.”
