Do I need anything in addition to FreedomFi Gateway to earn HNT for mobile data offload?

Yes. In addition to the FreedomFi Gateway you will need to buy a radio, certified to operate in the CBRS band. We are currently working with a number of CBRS radio manufacturers to certify their products’ compatibility with FreedomFi Gateway and the Helium network. We expect the radios to cost between $500 and $5000, depending on radio signal strength and throughput capabilities. The more powerful and expensive radios will enable owners to mine more HNT rewards.
