Did you know that you can take a Wi-Fi router and convert it for use in Amateur Radio?! Certain models of routers are supported and can be "flashed" with firmware (to replace the manufacturer's firmware). Only licensed Amateur Radio operators are legally allowed to do this.
Broadband Hamnet (BBHN) has been used to support local events, including MS-150 and ARRL Field Day.
