There is a testing ground by me, the local playing field, with trees on the edge, so it is perhaps a reasonable simulation of the limits of RSSI localisation, weathers nice tommorow so might give it a whirl. Or even better, paying me & Jeff to run around a field making Moo’ing noises whilst playing with all the kit we’ve not got around to testing
Or alternatively, buying a tried & tested solution. Look also at extending reach from deployed GW’s back to where you can effectively pick up internet connection - long range directional p2p Wifi or uWave links?Īll comes back to cost as you suggest - I assume you are charging for your time developing this as after all that is in part what drives the cost of off the shelf devices you consider expensive! IME no farmer ever says the price is too low - everying is always too expensive I think you need to start with mapping the area and topology then look at how a system and deployment needs to be developed and amended (yes there will be compromises to be made - this is no one size fits all in such cases), to accomodate what you find on the ground so to speak.
ARDUINO BLUETOOTH REPEATER UPDATE
How will a given node ‘know’ it has gone out of geofence limit to then send a message - are you running the node continuously to monitor itself live doing local GPS processing and position comparison (big battery!?) - also how will you update any Geo fence data (typically needed if you are to proactively move animals around the area, unless geo fence just relates to the fixed outer limits of the estate)
