Beijing, June 21 (QNA) – Spacesail, a Chinese satellite internet company, has achieved a major tech milestone, successfully completing direct-to-satellite voice calls using standard, unmodified commercial smartphones.
The firm stated that the entire communication link remaining smooth and stable throughout, while delivering excellent voice quality.
The field test showed full signal strength and voice quality on par with terrestrial 5G. Also, its high compatibility with existing mobile networks paves the way for deeply integrated space-ground communications, according to the company.
Earlier this month, China launched a Zhuque-2E rocket carrying two satellites, including Spacesail DTC 01. This Spacesail test satellite is designed to verify key technologies for direct-to-cell services and integrated space-ground networking, supporting the convergence of satellite communications with 5G/6G.
It is worth noting that the Spacesail Constellation had grown to include 200 satellites. (QNA)
