Abstract
An entry and starting system in an object has a control and transmission unit configured to use a radio link to interchange at least one radio signal and an ultrasonic link to interchange at least one ultrasonic signal with a portable electronic device. The control and transmission unit sets up a radio link to the portable electronic device and uses the electronic device via the radio link to stipulate at least one relevant parameter for a subsequent ultrasonic link. The control and transmission unit is additionally configured so as, following the stipulation of the parameters, to set up an ultrasonic link according to the previously determined parameters. The entry and starting system checks an authorization of the portable electronic device, the portable electronic device being detected as authorized if the at least one relevant parameter of a subsequent ultrasonic link is concordant with the at least one stipulated parameter.
