In today’s highly connected world, a reliable internet connection while on the move can be a necessity. There are many ways to connect to the internet, but most are on a large scale involving wired connections and access to 120 volt power. Here we describe a backpack containing a mobile wifi hotspot that can be powered by a lightweight lithium-ion battery and charged by a polycrystalline solar panel that can be stowed in the backpack or powered and charged via connection to an electrical outlet. The backpack can connect to mobile networks through a cellular device mobile hotspot and then broadcast wifi through a wireless router. The backpack has a wifi connectivity range in excess of 7 meters and can store enough energy for over three hours use for multiple network users. It can be charged quickly through connection to an electrical outlet or over a number of hours via the solar panel. This design offers a larger number of users access to the network than a typical cellular hotspot, a mobile battery to charge devices, and a solar panel for extended usage away from electricity. In the future, the next step for this design is to make the setup more convenient and power storage more efficient.
