1.) Check with https://www.ict-plus.ch They have a lot experiences with Long reach wifi... 2.) why not just a standard USV? Solar or Wind buffered... or is a normal power supply only sometimes available?

Hey Swinog,
does anyone have experiences with long distance (~20km) wifi powered by battery?
With have the situation that we basically want to connect Schwanden to Linthal by wifi for at least 12 hours.
The idea is to go via several hops, some of them not having any power resource.
So my questions to the list are:
- What kind of equipment have you used for similar cases or can you recommend?
- Are there any battery recommendations?
- Other creative ideas on how to get a direct link with >= 100 Mbit/s
connectivity?
Best,
Nico

Given big enough dishes and line of sight, this is achieveable. We had 40km links in rural areas of Iceland working. Its all a question of terrain, interfearance and right equipment. As far as power goes, a solar system can help to keep it operational.

Nico

Hoi Nico
Mit einem P?rchen Antennen wie diesen an jedem Hop ist das sicher machbar.
https://mikrotik.com/product/RBLHG-5HPnD
Als Baterien kannst du z.B. 100AH Autobateriene einsetzen, damit bekommst du ?ber 70h Betriebsdauer mit zwei Antennen...
Du musst jedoch daf?r sorgen das du zwischen den Antennen freie Sicht hast, sonst wird das nicht wirklich funktionieren.
Wir haben vor vielen Jahren mal einen WiFi Link zwischen Otelfingen und Regensdorf ohne zwischenhop gemacht (~8km), das hat mehrere Jahr stabil funktioniert. War jedoch anderes Equipment.
