The project started when I picked up four of FreedomPop’s 4G (home) broadband modems while they have been on sale. I have connected them together through a load balanced router so I have a fairly stable cellular connection to the internet when working in the field. As a result of this setup, there is a total of 4GB of free allocated cellular data. I am able to use the data anywhere by adding a wifi access point (AP) to the load balance router. The 4G broadband routers have built in wifi but I have disabled it so I can evenly distribute the data usage across all four cellular connections. With this setup, all I have to do is connect the box to a power outlet and connect my devices to the wifi AP. Here’s a quick diagram:

As you can see, I have excellent 4G (WiMax) coverage where I use the box. This map was generated while running a site survey on a WiMax enabled Android device:

Here is what one would need to get started. You can substitute parts as needed:
Check the Sprint 4G WiMax data coverage in the areas you plan on using it.
