T-Mobile and partner Nokia today said they successfully completed what they claim was the nation’s first two-way over-the-air 5G data session on a 3GPP-compliant 5G New Radio system. This means the mobile device was able to upload information to the network as well as download information from it. The pair completed the test in a T-Mobile lab using a simulated phone and Nokia's 5G NR equipment in the 28 GHz band. "This test is a big step forward in building real 5G that will work on actual smartphones," said Neville Ray, CTO at T-Mobile. According to T-Mobile, the companies relied on the Nokia AirScale baseband and radio, AirFrame server, and AirScale Cloud RAN with compliant software. They didn't say much about the simulated mobile device. T-Mobile and its competitors are rushing to roll out 5G services in at least some capacity by the end of the year. Each carrier is taking a slightly different approach. The goal of 5G development is to create service with 1 Gbps speeds, minimal latency, and advanced media support, such as augmented/virtual reality. T-Mobile says it will have 5G up and running in some markets by December. ”¯

Verizon and AT&T this morning refused a request by federal transportation officials to delay this week's planned launch of 5G service in the critical new C Band. [Update: By evening, the two companies agreed to a two-week delay.] The FAA (Federal Aviation Administration) insists that the service could potentially interfere with radio altimeters that planes use to measure distance to the ground in poor weather.

Verizon Details C-Band 5G Launch Plans, Promises 10x Data Speed

Jan 4, 2022
Verizon has formally announced plans to launch 5G in the new "C-band" mid-band radio frequencies later his month, and filled in details of what the launch will include. The company is promising to cover 100 million people — nearly 1/3 of the population — with the new network at launch.

Following C-Band 5G Debacle, FCC Considers Regulating Radio Receiver Performance

Apr 21, 2022
The FCC has launched an official proceeding to investigate how it can best address the issue of radio receiver performance. The FCC has historically regulated radio transmitters, but paid little attention to the technical aspects of radio receivers.

Verizon Ready to Light up More Mid-Band 5G Using Band 48

Jun 14, 2022
Verizon has successfully tested 5G technology in two different modes within band 48, also known as CBRS. At 3.5 GHz, this valuable mid-band spectrum is close to the C Band spectrum that Verizon recently deployed.

T-Mobile Achieves 3 Gbps Using Standalone 5G in Mid-Band

Jun 14, 2022
T-Mobile has successfully tested 5G triple carrier aggregation (NR CA) using 5G standalone (SA) and mid-band spectrum, achieving an impressive downlink data rate of 3 Gbps. Triple CA is not new, but non-standalone (NSA) 5G requires that one of those three carriers be slower 4G, limiting potential data speeds.
