[arm-allstar] USB Cell Modems

[Lu Vencl]

Careful. The E397u-53 is 3G only and that generation is going away. For example, AT&T will be shutting down 3G on February 22. I believe everyone else is already down or will be shutting down shortly there after.

The modem will not work with Verizon and if I recall it did not work AT&T either. These can be found on eBay and Amazon also sometimes has them.

I have a couple nodes I am redoing for one of the radio clubs that I maintain the repeaters for, and right now a point-to-point system is not looking feasible due to issues with the county. I would like to set up cellular primary via a prepay like Unreal Mobile/Freedompop, then have radios on local nodes for backup linking (two 70cm links between the two 2m repeaters, and a 2m base on the downtown
> 70cm) until we can set up a point-to-point system somehow.
