- the transmission of the detected occupancy state can take place in particular when the occupancy state is changed. However, it is also conceivable that the detected occupancy state is transmitted on request from the external unit or at regular intervals.
- processing unit is configured to transmit transmission parameters of the first communication unit as a function of the detected
- the sensor unit for detecting the occupancy state of the parking space may comprise, for example, an ultrasound sensor, light sensor, radar sensor, pressure sensor and / or magnetic field sensor.
- the device can also be arranged on or in a bottom of the parking space.
- external unit is meant, for example, a device which is centrally located in the area of the parking space and there as a gateway for the corresponding devices for monitoring the occupancy state of each pitch serves.
- the external unit can then transmit, for example, the received information about the occupancy statuses of the parking spaces to a server.
- server itself forms the external unit and the first communication unit communicates directly with this server.
- the transmission parameters of the first communication unit can be adapted correspondingly to the respective occupancy state as a function of this test result.
- the possible signal attenuation is taken into account by a vehicle, which is located on the parking space and partially shields the device.

- transmission energy is meant the energy with which the communication unit emits signals.
- the transmission energy is thus the transmission power of the communication unit.
- data rate is meant the amount of digital data transmitted over a communication channel over a period of time. The smaller the data rate, the longer the transmission of some information. If a band spreading method is used for a wireless communication channel, then the data rate can be adapted, inter alia, by the length of the selected spreading code. The longer the selected spreading code, the lower the usable bit rate, but the more robust the data transmission.
- different communication channels for example in their used frequency band or frequency range or the used physical channel bandwidth may differ from each other.
- the processing unit for monitoring the parking space thereto is provided that the processing unit for monitoring the parking space thereto
- the transmission energy may be lower than an occupied parking space, for example, to be able to transmit the detected occupancy state safely to an external unit. This consequently leads to lower energy consumption.
- this can also cause other units in the transmission range of the first
- the data rate can be selected higher than in a occupied parking space. Due to the lower attenuation, a successful transmission can be made possible despite a higher data rate. consequently For example, at a higher data rate, information such as the occupancy state of the parking space can be transmitted more quickly, which in turn can reduce the power consumption of the device.
- the processing unit is set up to select a different communication channel in the event that the parking space is not occupied than if the parking space is occupied.
- Parking space suitable communication channel can be selected.
- the communication channels of the first communication unit can differ in which frequency range is covered in each case.
- a occupied parking space for example, a
- Communication channel can be selected with a lower frequency range than a free parking space, as in a low-frequency or long-wave transmission better penetration, for example, from a parked on the parking space vehicle is given.
- the processing unit prefferably set up in the case of an unknown occupation state, the transmission parameters of the first
- a worst-case state is here, for example, a maximum signal attenuation of the communication channel to understand, which comes about by an occupancy of the parking space, since in this case the
