Britain Could Switch Off Airport Radar and Release 5G Spectrum 175
judgecorp writes "Britain is considering switching off air traffic control radar systems and using "passive radar" instead. A two year feasibility study will consider using a network of ground stations which monitor broadcast TV signals and measure echoes from aircraft to determine their location and velocity. The system is not a new idea — early radar experiments used BBC shortwave transmitters as a signal source before antenna technology produced a transceiver suitable for radar — but could now be better than conventional radar thanks to new antenna designs and signal processing techniques. It will also save money and energy by eliminating transmitters — and release spectrum for 5G services."

Seriously... You've not heard of 5G? It's a whole G better than that dowdy old 4G. Better start saving up for it today!

The stealth fighter is not really stealthy, we know about it otherwise if it was truely stealth we wouldnt even know it exists.
Then again it can be picked up by weather radar also. Its a huge failure.
Perhaps the current stealth fighters are just cover technology for the real ... wait a minute someone's knocking at the door

Well, yocto is an official SI prefix, meaning 10^(-24). So you need 1 000 000 000 000 000 000 000 000 yoctobytes to store just one byte.
Now to store the complete internet in several yoctobytes, you must have an extremely good compression algorithm. :-)

Cat5 cable is purpose built for the task.
If that's not enough the natural solution is to log onto the net with cat5e for 2.7 times more bandwidth.
