Japanese carrier NTT Domoco and Finnish equipment maker Nokia demonstrated 5G technologies at an event in Brooklyn last week.

The companies showcased a phased-array antenna system to enable multi-gigabit speeds in 90 GHz spectrum, along with dynamic offloading relocation in a 5G core. Officials vowed to continue testing those technologies at the carrier’s lab in Japan.

“Working together, we want to accelerate the evolution of 5G technologies especially towards pioneering higher frequency bands such as 90 GHz,” said NTT Domoco CTO Hiroshi Nakamura.

A Hong Kong cloud services company on Thursday announced a new service designed to ease mobile data costs for frequent international travelers.

uCloudlink officials said GlocalMe Inside, which will be available on select devices for a monthly fee, would ensure “fair local data charges” in more than 100 countries and regions using CloudSIM technology and “extensive” partnerships with carriers.

“We hope this service innovation can turn many silent roamers into active ones, addressing one of the most pressing challenges facing the entire industry,” co-founder and CFO Simon Tan said in a statement.

A smart watch developed for young children was selected as the winner of a startup competition at the Competitive Carriers Association’s Mobile Carriers Show earlier this month in Las Vegas.

Oaxis, a Singapore company, finished ahead of seven other startups in the pitch contest. The company’s myFirst Fone S2 features voice and video calling, along with safety features including GPS tracking and geo-fencing.

“Our children’s safety and security are of heightened awareness across the globe,” said Oaxis CEO G-Jay Yong. “With myFirst Fone S2, Oaxis is harnessing the latest technologies to give parents piece of mind while offering a 2-way controlled communication device that keeps children engaged.”
