I'm trying to mod a sim based hotspot. I want to take the reuter which is somewhat fragile and not at all impervious to the elements and place it in a rugged waterproof case eg a pelican case with a larger antenna eg 35 dbi antenna, a large battery bank eg 20000mAh and a small solar array to charge the battery during the daytime. The goal is to have as simple a main interface as possible eg a single toggle switch which allows the reuter to broadcast 802.11 wifi while the battery is on and being charged by the solar panel. The help I need is in sourcing the parts (excluding the reuter which I have and the antenna) and designing the circuitry necessary to create a fuctioning version of this idea. Please dont hesitate to reply
