As part of the agreement, Ericsson will update T-Mobile with the latest 5G New Radio (NR) software and hardware compliant with 3GPP standards.
Alongside hardware, Ericsson will also provide digital services, including dynamic orchestration and business support systems (BSS), along with its Ericsson Cloud Core product, enabling T-Mobile to more easily launch 5G experiences to its customers.
"While the other guys just make promises, we're putting our money where our mouth is", said Neville Ray, T-Mobile chief technology officer, in making today's announcement.
As the United States races toward commercial 5G services, Ericsson achieves significant milestones with AT&T, Verizon and T-Mobile on the road to making 5G a reality for consumers. The provider moreover acknowledged Nokia would succor bag its "600 MHz and 28 GHz millimeter wave 5G capabilities compliant with 3GPP 5G Unique Radio (NR) requirements" - echoing its fresh plans with Ericsson.Ericsson ranks as the supreme dealer of cell network technology earlier than Nokia.
Bridging from a nationwide LTE Advanced network to 5G, T-Mobile will take advantage of Ericsson's 5G portfolio to grow existing LTE capacity needs while future-proofing the system.
The Ericsson agreement is the company's second recent multi-billion dollar 5G deal.
Fredrik Jejdling, Executive Vice President and Head of Networks at Ericsson, says: "This accomplishment shows that 5G is ready for business. This successful over-the-air test using the band that will offer 5G services in North America, also demonstrates the network and ecosystem readiness we have achieved".
Both European vendors have undoubtedly benefited from the USA clampdown on Chinese rivals Huawei Technologies Co.
Claims to "5G firsts" will continue to be made until 5G deployments are in full swing next year, supported by finalized 5G NR standards, spectrum auctions, and relaxed regulatory policies.
While the 5G rhetoric is beginning to pall, it's at least a measure of the industry's excitement about the technology - which it hopes will translate into customer sign-ups, loyalty, and new revenue streams.
And there are still hurdles to overcome, not least 5G's limited range and penetration.
