This SDR sunday (Software Defined Radio) is all about 60 GHz radio technology, 
usecases, challenges and potential problems.

It is the largest ISM band (in europe) with space of 4 times about 2 GHz, capable of 
speeds of up to 7 gigabit per channel, over less impressive distances (10 meter, line
of sight) due to heavy absorption by oxygen. Automotive radar is relatively nearby
(76 GHz) and has much less this problem. At 60 GHz or 5 mm (V band) it is a great
band for wireless video for VR headsets transmitting GPU rendered HDMI graphics at
2160x1200 or higher resolution, with a few msec-level low latency @ 90 frames per second.

Standardised protocols include the existing wirelessHD products on the market, like 
the TPcast solution for HTC vive VR, and to-be-incorporated wifi series 802.11ad 
and 802.11ay claiming similar speeds with different modulation and coding 
schemes.

Picking up a 60 GHz signal or determining the power level and antenna's beam is a 
challenge, several solutions toward this will be presented. There are ways
to process it in software as well, but be wary that the ADCs to do so produce up 
to 8 times 16 gigabits per second - which could saturate a 100 gbit ethernet 
connection with raw IQ samples.
