I'm wondering how the natural motion of some taller buildings affects this kind of deployment.
Lots of buildings swing and twist in the normal course of the day. We found this out with some of the free space optical solutions available.
- walrus01 10y agoIt can have some effect but at the distances aimed (max 3km for a high reliability, high Tx power 80 GHz link) it doesn't affect much. A link that is a nominal -34 RSL on a clear sunny day might drop to -36.5 as a result of building sway (such as if one end is on top of a 60 floor tower). Weather is the main issue not heat expansion/contraction or sway.
