Packet Radio does not beat Xbee, neither for distance, speed, nor price. The only way I can see Wifi helping this project is in conjunction with Eyefi. I'd like to avoid leaving a PC in the woods. I'd welcome any new ideas please be specific. So let's begin there with an Eyefi card in my camera. Please walk me thru how antennas and higher power might help. I am very experienced with these things in the Ham world for 35 years. I should hook an antenna to the Eyefi? An RF amp? No. So I need a portable router. Up in a tree? At ground level it wouldn't be good enough. There is terrain between us. Thick trees. Maybe the camera would be next to a big rock on the wrong side. Certainly a tennis can antenna would be useful at the base station. Keep in mind this is not line of sight. A router up high needs to be powered, for days. How to make it waterproof. What is the best price you can find? I'm thinking $50. What antenna would you recommend in this case? It needs to go in 2 directions at once. How do you increase the power of Wifi? I've tried the higher powered USB transceivers for a client, they are crap for less than $100. I would need 2-3 of them.
My constraints are flexible guidelines and not meant to be rigid. I'm the designer and the client all in one person, so I'm trying to make it easy to get along with myself
200-400m. $50-$150. Even the quality of the JPG image is not fixed, it can be very lores. Every minute or every hour. I could use a cheap Canon that supports PTP or my good camera when the location is safe. Sometimes I may want to use this unit in the desert or across a small bay where it is line of sight. Other times thick woods in the Northeast, or a dense rainforest in S.America. I cannot use the cell phone network. My suggestion was for Ofransen. I'd be happy to write the code for him just for fun! Since it will only take an hour max to modify mine once he has learned to initialize the hardware and the GPRS connection. Did you read the AT commands for this? You do not agree it is simple? There is simple vs complex. And easy vs hard. Something can be simple (not complex) and hard like lifting a big rock. Or complex and easy like accounting maybe. I think sending data you already have in a buffer is both simple and easy with a code library.
I'm sorry if I have left out some information about what I'm trying to do. I feel I'm writing too much. Did you read the other thread? If I forgot some detail please ask. Sometimes I am thinking out loud. There are many details missing because I have not decided how to implement my goal.
Simply: I want to see what the camera sees without wires. And take better pictures to be stored in the camera.
If we start over from square one does that help?
