Wireless network without grid connection
Wireless network without grid connection
I'm interested in hearing from anyone experienced with networking gear and software. Can you confirm if this setup is feasible and share the best approach? We need to cover a range of 0.3 to 0.5 miles, connect trail and security cameras, and send footage to a power-free host at camp. The system should run on battery and solar power, and it would be helpful if cameras could transmit images or videos. I'm new to embedded systems but open to learning chip programming if needed. This sounds like a great project to highlight on my resume. What do you think?
Unlikely. This will demand some specialized gear. Consider PtMP (point to multi-point) wireless distribution. You may need sector antennas to reach areas around the base. For power, you’ll have to determine that separately. Many of these units can function well on solar power.
It’s actually straightforward, even with off-the-shelf equipment. Motion-activated trail cameras are widely available and often powered by built-in solar panels and batteries. The catch is you might need a special license to operate them. Most 802.11 standards use unlicensed ISM bands that consume very little power—usually no more than half a watt—and operate in microwave frequencies, which struggle to penetrate thick vegetation. 2.4 GHz works well for short-range transmission through drywall, but with high-gain antennas and solar power, you could potentially make it function. For deeper penetration through dense foliage, you’d need UHF bands (300–1200 MHz). GMRS and amateur radio both cover those ranges and can deliver the necessary 5W for transmission; however, hardware for GMRS isn’t widely accessible. Amateur television is another option, though it’s a more expensive pursuit.
