(07/31) After reviewing our options, the design team has placed an order for an FSK based single chip radio solution (SI4420). These radios fulfill all our previous requirements except the built in feature for data encryption. This actually works out better because now we have full control over the data encryption algorithm that we can incorporate into the microcontroller itself.

Are you planning a USA model since unlicensed operation is prohibited in the 420-450MHz band?  Encryption by non government users is also prohibited in this band in USA.

  Are you sure? yes | no
