Optus, Nokia detail upper 6GHz test outcomes
Australian operator Optus joined a growing upper 6GHz movement, completing tests with Nokia it stated could be fundamental in an eventual transition to 6G.
A trial involving a robot dog is one of the items the pair researched. Optus explained the work validated the ability to automate mobile signal measurement, which it stated would have uses in designing indoor 6G networks.
Less showy but equally necessary were tests of advanced antenna technology and use of wider spectrum bandwidths. Optus and Nokia used current 5G infrastructure, but the operator expects the results to offer insights for indoor and outdoor 6G.
Optus stated the pair also explored ways 6G technologies could be localised for Australian demands, with an eye on the requirements of AI services, automation and future digital services.
The capability of upper 6GHz was proven through tests on Optus’ 5G network, with peak download data rates of 3.5Gb/s provided to a smartphone using a MediaTek modem in a set-up employing compatible Nokia massive MIMO antennas.
Optus CTO Sri Amirthalingam said the data rates show “the significant opportunity” upper 6GHz can deliver “for future networks”.
He said the capabilities trialled are set to be important elements in AI-native networks and the digital services these would unlock.
Momentum around upper 6GHz is building and GSMA experts believe it is now ready for real-world use because a designation as a key band means operators can begin planning investments.
Nations are jostling for a leading position in the band’s development and regulators are beginning to explore how best to employ it.
