I am a new member of expert exchange and I have a new contract which left me with a bit of questions. So let me explain the situation.
I have to deploy a network on a farm. Installation of the network itself should be a breeze. The reason of this network is to read cow temperature. Each cow will be installed with internal wireless transmitter which reads the cows internal temperature and let's the farmer see any significant change in the cows temperature which let's him monitor the cow for potential problem/disease. Each transmitter will send a signal to the receiver every X minutes. Those transmitters are then connected to the network (see http://www.bellaag.com/
for more info).
Here is my problem. The farm is divided in 3 separates sites. Site A is where the server will be. Site B is a small site with some cows. Sites C is the site where we can find the most cows and where I expect the most network traffic. EACH of the sites will be on their own network (actually it is possible to make Site A and B one network which is what I might do). So to make this easier let's just say right now that SITE A and B are one site and C is completely separate. As far as I can understand the transmitters have to be on the same subnet (information that I will have to confirm here I am already in contact with BellaAg for more technical information).
Every site has their own internet connection but right now are completely separate. The software taking care of those readings will be installed on the server in SITE A. Please also note that I am not a specialized in networking so some patience and explanation might be required.
For now my question is: How do I make the contact with SITE A and C? Temperature readings will be going through the network at SITE C but they do need to end up and merge with the readings and site A and B. To make this a bit more complicated we are looking for a low cost solution. For some other software that we will be using we have thought of remote control on the main server from every computer installed on the farm (please note we are aware of the limitations of this method). There is no price for this low cost solution but a server/domain solution was not very welcomed it seemed (but if it's the only solution it will have to do). So do not limit the answers to the low cost solution problem but try to keep that in mind when giving an answer.
If you need more information please let me know. I am also talking with BellaAg at the moment so more in depth information will also be available if needed.
