ESP8266 Community Forum

- Wed Jun 20, 2018 9:06 pm #76538 I am doing a project where I need to transmit from an ESP8266 module to a router from any two locations inside a house.

Using some sort of antenna or other booster, not oriented in a specific direction, is it possible to transmit through multiple walls inside for a range of 75 meters? The ESP doesn't have to receive from the router at all, only transmit to it. I am assuming the router quality is an average household router, which can't be modified.

A constraint for the project is to be self-contained, so some sort of repeater is out of the question.

Also, if you know of some non-ESP solution to this, I'd be interested in hearing that too.

Thanks for your help.

WiFi is allways two ways.

Place them halfway or it there is a metallic obstacle blocking the signal place them so they can triangulate around it.
