11 Customer Support & 3rd party network 3 Classes of Customer Supported Expert Experienced RF Designers Build their own layout, matching, protocol, antenna, etc. Require silicon only and minimal support May have worked with the competition already Intermediate RF Engineers with minimal knowledge of ISM/SRDs May need some help with layout, matching & antenna design Require low level software drivers Novice Customers who need complete solution. Require layout, reference design, matching, antenna design Want working software protocol Most 3 rd Parties buy from Distribution 11
