MIM100 Upgrade Kit

This is our original first generation internet solution. The MIM100 was hugely popular. These were a category 4 4G/LTE modem which meant that it was capable of a maximum download speed of 100Mbps and upload of 50Mbps. While this sounds like more than enough, the reality is that you will never see these speeds, (even if right next to a cellular tower).
