thank you Woland , i understood all except the place of the GESP
it will be like this : mikrotik router - GESP - POE adapter -- cable - GESP - Outdoor Access point correct ? both should be GESP POE i think or only the second one ??
Hi,
GESP - POE: you need just a single one so that you can feed the AP and you can feed the ap through a non PoE GESP:
Router---PoE GESP ---long cable --- GESP--AP
@Larsa: I don´t agree. It does very much matter to have measures against lightning and also a massive metallic case can be such a measure and a very effective one.
The lightning mostly doesn´t hit an antenna/AP directly and the amount of energy transfered by lightning bolts generally varies a lot.
Also consider this: if you have a metallic casing with low resistance, the energy of the lightning is not going to be dissipated in the casing. Also if you looking at the lightning as a current source, you will have a very low voltage between the entry point on the casing and the exit point, because the resistance is very low.
The quality of household electric installations varies wildly, but the more you do against lightning damage, the less the chance your equipment will die.
However you should never just install surge protectors and think you are all set. In fact good grounding and potential equalization combined with proper lightning protection are needed.
Actually the current lightning protection norms in residential buildings in the EU are sufficient for household protection. There are of couse different levels defined and the higher level you have (IV is the lowest level ) the higher is your chance to survive a hit.
You can do a lot about lightning protection, but it costs you money, time and effort, so many times people just ignore it.
