Telecom Italia launches Open RAN test and integration center
Telecom Italia (TIM) has launched an Open Test and Integration Center (OTIC) lab dedicated to Open RAN products, following the lead of other major European telcos. The TIM European OTIC Lab, approved by the O-RAN Alliance, will be based at the group’s innovation laboratories in Turin.
The new facility will work with major providers spanning the whole Open RAN ecosystem, as well as start-ups and system integrators, to test new components and accelerate deployment of the technology across Europe. Meanwhile, TIM pointed out that it has recently implemented Open RAN technology for a live network in the city of Faenza, in cooperation with US-based JMA Wireless.
This follows various moves by other European telcos towards RAN disaggregation, and the memorandum of understanding signed in January 2021 by Deutsche Telekom, Orange, Telefónica, TIM and Vodafone to encourage roll-out of Open RAN in future 5G networks.
Verizon harnesses mmWave spectrum for private 5G network
Verizon Business has launched its private 5G network service, On Site 5G, offered both to large enterprises and public sector customers. The package, incorporating mobile edge computing (MEC) and machine learning, will use the company’s millimeter wave spectrum, but be configured initially as a 5G Non-Standalone network connected to an LTE core.
For MEC, Verizon is working with AWS to deliver distributed compute and has Amazon Wavelength Zones set up in 10 cities.
AT&T completes 5G field test calls
AT&T is claiming a first for C-band spectrum in the 3.7 GHz to 4.2 GHz range by completing 5G field test calls successfully, using a mobile test platform at locations in Plano, Texas and Detroit, Michigan. Operators want to start utilizing their expensive C-band spectrum as quickly as possible, with both Verizon and T-Mobile USA also conducting tests.
AT&T acquired about 80 MHz of C-band spectrum nationwide with plans to cover 200m people with 5G over these airwaves by the end of 2023. The carrier said that, even before the auction ended, it was developing a test strategy for the new airwaves, and was not prepared to wait until the spectrum was officially available.
