Lab boosts wireless speeds to 2.5 terabits per second

Using "twisted vortex beams," American and Israeli scientists have boosted wireless transmission speeds to 2.5 terabits per second.

As explained in ExtremeTech, the researchers "use orbital angular momentum (OAM) to cram much more data into s single stream." Current technology uses SAM (Spin Angular Momentum). These results came only a few months after Bo Thide at the Swedish Institute of Space Physics proved OAM is possible, and sent a signal over 442 meters (1450 feet).

The 2.5 terabits per second test twisted eight 300Gbps light streams around each other, but only transmitted them for one meter (three feet). Alan Willner and others at USC, NASA's Jet Propulsion Laboratory, and Tel Aviv University believe successful implementation could boost wireless throughput by 1,000 times or more.


It will bring costs down. 1000 times more bandwidth without the bidding wars for spectrum.

I want it now!

Not so fast

So yes, this is great news, just don't expect it to upgrade your home wifi network or LTE connection to said 2.5 terabits.

until the rest of the computer hardware works that fast, it is nothing but an academic paper.

I don't know much about the science, but anyone who claims their new breakthrough has an infinite capacity immediately sets off my skepticism.

More applications

Given that OAM is a modulation technique, which is a physical-layer tech, nothing above firmware will even know about it.

OAM has promises for broadcast as well, it needs a lot more work though.

So it'll be great for things like backhaul networks, satellite linkups etc, but it won't solve the problem of mobile wireless access (WiFi/LTE/etc).

Now the US and Israel can spy on everyday citizens even faster!!

Tell us how fast your network connection was when you first got into computing: 300 baud, 10Mpbs, etc.
