It seems most of what I still notice are the Cielo radios. But almost
all of the HFT Guys in Chicago have switched over to the Ionosphere
antennas. Where they have the huge yagi antennas with just a single
licensed link back to the Datacenter. I can count 10 different sites
within 15 miles that are using this setup. One of the towers we are on
is in the process of installing a 3 antenna system, 30'x40' antennas at
100', 125' and 150'. Single licensed radio back to the CME datacenter.

There is a whole other class of low-latency wireless gear. FEC is
removed. ARQ is nowhere to be found.
The radios are optimized so that the data spends as few picoseconds as
possible in the radio.

All the licensed gear I know of is full duplex, and should have near
wire speed latency. The latency should be proportional to the link
distance.

Anybody here up to date on current ultra low latency licensed PTP
gear? Like in HFT networks. Trying to round up the current players.
