Good morning all!
Working out a concept that will allow me to play around with "mapping" my parcel of land (planted saplings etc, food plots etc).
My question today is this; is there a way to use Arduino and a Wifi shield (or other component) to create a large mesh of access points in open terrain (without obstructions, each access point or "node" will have a self contained power supply backed up by a solar Panel) that could transmit a signal say 5-1km omnidirectional?
I plan to mess around some with WIFI RSSI/dBm conversion and gradually "map" the terrain in 2D, using each location set as a "map coordinate" eventually working into trilateration for generalized location tracking.
Speed is not an issue (as a simple ping should be about 28 bits per my research), power supply is not an issue (I can power it from anything such as a large marine battery down to a LiPo if necessary). By biggest concern is being able to create a large enough mesh with out needing an access point every 150-300 feet.
Per my experience in the drone world 5.8ghz is by far the best to go with, but I'm not objected to 2.4 if it's the only thing feasible.
Any help, pointers etc are much appreciated. I haven't messed around with Arduino all too much but have gotten my feet plenty wet with it.
ALSO - please no "just use GPS" comments. I'm actually trying to go somewhat old school, and design a product that does not require a GPS signal.
