It's okay if you've never heard of wireless broadband bonding. The technology hasn't exactly caught on, even if it gets us all excited in our download place. The basic idea is to take a suite of wireless broadband adapters and plug them all into a single router, aggregating their power like shotgun modems did in the dial-up days. Mushroom Networks is the leader in this space and it has announced a new, "heavy duty" version of its PortaBella bonding device, joining its Porcini and Truffle models. The new PortaBella combines the connections of up to four wireless modems, even from different carriers, and works at temperatures ranging from 4 to 158 degrees Fahrenheit -- which sadly doesn't quite meet the extremes experienced on an average day at the Engadget Lunar Outpost. It seems our heavenly bloggers above will have to keep sharing that single modem for now.
