Conventionally, there are a few methods of effecting conditional access for a system with devices to be activated and/or authorized in the field. Broadcast systems, such as, for example, Satellite Digital Audio Radio Services (“SDARS”), transmit conditional access information in a 1-way manner and use multiple repeat methodologies to ensure receipt of such information by the devices. Point-to-point systems, such as, for example, telematics systems, generally transmit conditional access information in a 2-way manner and use acknowledgement methodologies to ensure receipt of such information by the intended devices.
