Japanese researchers hit 3Gbps using T-Rays

Japanese researchers hit 3Gbps using T-Rays Japanese researchers achieve very high speed using terahertz band.
They managed to hit a data rate roughly twenty times higher than the best that can be achieved with Wi-Fi, using the unregulated terahertz (or T-Ray) bands. The band makes use of the 300GHz to about 3THz frequencies.

The Tokyo Institute of Technology researchers, demonstrated 3Gbps transmission at 542GHz using a wireless radio no bigger than a 10-yen coin (about the size of a British penny coin). They suspect that they could push the speed up to about 100Gbps.

The next generation 802.11ac standard, which hasn't been approved yet by IEEE, can offer speeds theoretically as high as 1.3Gbps with three antennas, though the maximum achieved in tests so far was closer to 800Mbps.

The proposed 802.11ad standard (WiGig) could theoretically manage 10Gbps data rates, but generally only within line of sight range.

While the T-Ray bands do offer some promise, they will only be useful over short ranges, which could make them useful for server farms or data centers where they can cut down the amount of wiring.

Of course you only keep the full speeds within line-of-sight, but they say likely not good for covering large distances. I wonder though, these frequencies aren't commonly used and shouldn't face much interference should they? So even with a high percentage of signal degradation at a distance, you should be able to keep full functionality at a greater distance than the current N standard.

Can't wait to see the next wave of wireless tech, I wish it could be expedited somehow lol
