Abstract: The invention relates to safety or control systems for a plurality of sensors. In particular, the invention relates to networks for transmitting measured parameters, control or similar signals by modeling signals at carrier frequencies using a wireless electric communication, preferably, using a radio communication. A method for a radio communication among a plurality of transceivers of a safety or control system comprises broadcasting a radio signal, which comprises at least a preamble and a packet body, and searching for the preamble through a plurality of antennas k1 of one transceiver with an alternate periodical linking of each antenna to search for the preamble followed by evaluating a quality of the radio signal as compared to a given level of the radio signal upon receipt of the preamble and selecting an antenna having a maximum level of the radio signal, through which a synchronization of the transceivers is started to receive the packet body.

Abstract: The claimed group of inventions relates to method for enhancing a communication between security sensors and a transceiver within security alarm systems, which could improve an interaction between the transceiver and at least one sensor of the system by performing a real-time correction of its operation, by performing a control of synchronization parameters of the sensors, timely introduction of the corrected parameters and use of an accumulated data for self-correction of the synchronization parameters by the sensors. The implementation of the claimed methods reduces a probability of internal mutual interferences, provides a correct operation of the sensors, increases an autonomous operation time of the sensors and an overall stability of the security alarm systems.

Abstract: The invention refers to wireless safety systems and it relates to a method for transmitting data by a sensor of a wireless safety system that enables to transmit massive data to large distances (up to 2000 m). A method for transmitting data by a sensor of a wireless safety system that comprises at least one sensor and a receiver, which are coupled by means of a radio communication, is proposed. The method comprises: continuously exchanging data and/or data announcements, which are transmitted, by sending statuses and/or alarm signals through a main radio channel between the sensor and the receiver that is equipped with at least two radio modules, which are configured to perform the continuous data exchange, and activating a separate data channel for the data transmission using one of the radio modules that is not used for the main radio channel, and with a decision making unit.
