Abstract
The invention relates to a beacon for broadcasting data to a plurality of devices in a certain range comprising—an interface for receiving a signal—a processing unit which is arranged to generate a control signal for an adaptation of a transmission of data depending on the received signal.
Claims15
Beacon (B) for transmitting data to a plurality of devices in a certain range comprising
- an interface (I) for receiving a signal
- a processing unit (PU) which is arranged to generate a control signal for an adaptation of the transmission of data depending on the received signal.
Beacon (B) according to any of the previous claims, wherein the signal is
- a signal received from a device, in particular a mobile communication device or/and a beacon (B),
- or/and a signal received from a sensor, in particular a sensor for detecting a quantity to be measured in the environment of the beacon.
Beacon (B) according to any of the previous claims, wherein the beacon (B) operates according to a Bluetooth standard, in particular according to one of the following protocols:
- iBeacon
- AltBeacon
- Eddystone
- UriBeacon.
Beacon (B) according to any of the previous claims, wherein the sensor is integrally designed with the beacon
Beacon (B) according to any of the previous claims, wherein the sensor comprises at least one of
- a light sensor for determining light intensity in the environment of the beacon (B);
- a motion detection sensor for detecting motion in the surroundings or a part of the surroundings of the beacon (B);
- a temperature sensor for measuring the temperature of the environment of the beacon (B);
- a receiving unit for receiving signals from devices around the beacon (B).
Beacon (B) according to any of the previous claims, wherein the beacon is adapted to work as a transceiver outside a time interval where a connection is set up.
Beacon (B) according to any of the previous claims,
- wherein the beacon is adapted for detecting the presence of a beacon transmitting according to a wireless transmission standard, in particular a Bluetooth standard,
- and wherein the beacon is suited for communication with neighbored beacons, in particular for exchanging information in regard to the transmission power which is to be used in a position determining method.
Beacon (B) according to any of the previous claims adapted for detecting the presence of a device not being a beacon, in particular a mobile phone, by determining whether a received frame is from a beacon, in particular by decoding at least one received frame and wherein upon detection of a non-beacon device the transmission rate or/and transmission power is increased.
Beacon (B) according to any of the previous claims, wherein the beacon is adapted for receiving a signal from a non beacon device requesting a transmission rate or/and transmission power.
Method for adapting a transmission rate or/and transmission power of a beacon comprising the following steps
- broadcasting, by the beacon (B), data to a plurality of devices
- receiving, by an interface (I) a signal
- adapting, by a processing unit (PU), the transmission rate or/and transmission power depending on the received signal.
