Wireless Chip Breakthrough for Eventual 6G Speed that is 100 Times Faster Than 5G

Singapore researchers have a terahertz (THz) wave chip that can transmit at a data rate of 11 Gigabits per second (Gbit/s). It is capable of supporting real-time streaming of 4K high-definition video and passes the theoretical limit of 10 Gbit/s for 5G wireless communications.

The small silicon chip has rows of triangular holes. The small triangles pointing in the opposite direction to larger triangles, light waves become “topologically protected”.

This all-silicon chip demonstrated it could transmit signals error-free while routing THz waves around 10 sharp corners at a rate of 11 gigabits per second. It gets around any material defects that may have been introduced in the silicon manufacturing process.

This technology could be the basis for next generation ‘6G’ communications with terabytes-per-second speed (10 to 100 times faster than 5G) in future.

THz interconnect technology will be used data centres, IOT devices, massive multicore CPUs (computing chips) and long-range communications, including telecommunications and wireless communication such as Wi-Fi.

  1. I cannot imaging this being used outside of the chip or in a shielded box. Not sure I would want to put a THZ generator next to my head. Replacing WiFi or Bluetooth wouldn't work for me in that regard.

  2. I think that the future of urban 5G/6G and beyond belongs to Artemis’s pCell. For rural/global coverage, it’s Starlink.

  3. At last a solid plan for getting millions to settle on Mars:
    “Got the new terahertz Apple 6G phone? Want to actually use it? Come to Mars – our new surface-suit helmets are Apple 6G compatible!”

  4. Here is the thing, you are only talking from a feasibility standpoint. It wasn’t until LPDDR4 that we had mobile ram at 3.2Gbit/s, read the timeline here:

    That means we just go to: Dec. 2019 16GB10nm-class 12Gb+8Gb LPDDR5, 5500Mb/s

    They are “hoping” to get to 6400Mb/s soon:

    As Samsung continues to expand LPDDR5 mobile DRAM production at its Pyeongtaek site, the company plans to mass-produce 16Gb LPDDR5 products based on third-generation 10nm-class (1z) process technology in the second half of this year, in line with the development of a 6,400Mb/s chipset.

  5. 11 gbit/sec Dynamic memory is easy to do…. you just make the data bus width wider to the memory by putting dynamic memories in parallel …. static ram is a even easier… imagine ….64 bits of data getting clocked into a static memory every cycle at 2 gigahertz….

  6. No, you’ll still be incel, you’ll just be downloading a different category of cartoon p()rn to mope over.
    Thus increasing data usage, thus increasing the profits of the 6G networks. It all makes good commercial sense.

  7. This technology, when available, will be more akin to WiFi than to a cellphone service.

    The stations will need to be literally a few meters from *everywhere* if you want such service.

    Which is (let’s point out) good business if you make and sell the stations.

  8. Signal attenuation set aside. Getting this onto a chip is not so easy.

    • Signal to noise ratio on chip, etc.
    • 11Gbit/s write/read memory is just not there.

    Pointing to some fancy unscalable memory tech as a solution is fallacious talking point. A consistent 1Gbit is more realistic. Right now even phones that are getting 700Mbits+ it’s not consistent.

  9. Exactly. from wikipedia…”Terahertz radiation is strongly absorbed by the gases of the atmosphere, and in air is attenuated to zero within a few meters, so it is not usable for terrestrial radio communication”.

  10. The problem is that higher data transmission requires higher frequency, but those higher frequencies have a horrible attenuation in the atmosphere.
    The key step to higher transmission speeds by radio (and I don’t think there’s any use to this) is to use a higher frequency range with little atmospheric attenuation.
    That’s PAST 10 THz!


  11. If 5g gives you Covid, heavens knows what 6g will do. Change your sex everytime you make a phone call or something.

  12. It seems that they have demonstrated on chip transmission of data. That is, no demonstration of any “wi-fi”…
