A method for transmitting a beacon message, the method generating, with a beacon generating device at least one beacon message, wherein the at least one beacon message is defined by a beacon message format, wherein the beacon message format comprises a preamble field, an access address field, a protocol data unit (PDU) field and a cyclic redundancy check (CRC) field, wherein the PDU field comprises at least one electronic product code (EPC) encoded EPC-PDU field, and transmitting, with the beacon generating device, the at least one beacon message using a Bluetooth Low Energy (BLE) wireless communication protocol to a transmission area within a transmission range of the beacon generating device for reception by one or more beacon receiving devices located in the transmission area.

Method and device for bluetooth low power communication

This concerns a Bluetooth Low Energy (BLE) device, or system, or method of operating a BLE device and a respective computer program. The BLE device comprises a transceiver to broadcast the at least one advertising packet, a processor connected to the transceiver to generate the advertising packet and/or to trigger broadcasting thereof according to a broadcasting schedule. The device further comprises a verification element connected to the processor and being capable of ascertaining if a predefined condition is met, at least one of the verification element and the processor is capable of modifying the broadcasting schedule based on the predefined condition's ascertainment.

Method and system for optimized bluetooth low energy communications using dynamic broadcasting schedule

A narrow band receiver or transceiver for processing electrical signals. The narrow band receiver or transceiver includes an amplifier, a voltage controlled oscillator and a tuning assembly comprising at least one control loop for tuning of the voltage controlled oscillator. At least a gain control of the amplifier is coupled to the control loop for simultaneously tuning the output amplitude of the voltage controlled oscillator and the gain of the amplifier. A compensation of the effect of variation on the gain of the amplifier, which includes an LC tank circuit, is performed by using an information in another LC tank circuit of the voltage controlled oscillator in the control loop.

Narrow band receiver or transceiver

The automatic gain control unit for a radiofrequency receiver includes a first current source for charging a storage capacitor by a first current, four comparators for comparing on the lower side an in-phase positive intermediate signal, an in-phase negative intermediate signal, a quarter-phase positive intermediate signal, a quarter-phase intermediate signal with a first reference threshold to a high amplitude level of the intermediate signals. Each comparator controls a MOS transistor connected in series between a second current source and the storage capacitor in order to discharge the storage capacitor when each transistor is in a conductive state. A bi-stable trigger element is connected to the storage capacitor and to provide an AGC signal depending on the voltage level on the storage capacitor for attenuating or not the gain of the low noise amplifier or of a mixer unit amplifier of the receiver.
