China is barreling ahead on ultrafast wireless technology, quietly hurtling the world’s first 6G test satellite into space while the US is still rolling out 5G at a snail’s pace.
The satellite, called Star Era-12, has frequency bands so high that they have to be tested in space so the signals won’t be lost as easily as in air, the National Science Foundation’s Thyagarajan Nandagopal explained to The Post.
Exactly how fast the bands are isn’t known, but Nandagopal estimates a range of 100 and 500 Gigahertz, or Ghz — 100 times faster than 5G. To understand that speed, compare 5G and 4G cellphones: A 5G model is 100 times faster than a 4G, depending on the carrier.
What 6G will touch covers everything from communications to telemedicine to national security, according to Professor Tommaso Melodia, who heads Northeastern University’s Institute for the Wireless Internet of Things. And along with
