> In 20 days, Project Taara lead Baris Erkmen says the link transmitted nearly 700TB of data
700 TiB / 20 days ~= 3.56 Gbps
700 TB / 20 days ~= 3.24 Gbps
20 years ago, fully open source design, 10Mbit https://en.wikipedia.org/wiki/RONJA
Very cool. I'd like to better understand the difference between this and other line of sight transmission stuff. I assume bandwidth and latency, but not sure the orders of magnitude.
Why use this instead of line-of-sight microwave links? Increased bandwidth at the expense of range?
What happens on a foggy day?
Aoptix was a company that did much than this more years ago. Founded in 2000 and despite 16 years and $150M raised, they could not find much of a market. The Aoptix system could transmit 4x this Google system, had further reach, and achieved 5 nines reliability.

The main problem with wireless optical backhaul is the high cost. It cannot compete with RF wireless.
