Bluetooth 5 is the next evolution of wireless communication technology that has established itself for good in the mobile device sector, as well as in our devices. Thanks to its versatility and flexibility, it is an important pillar in the development of IoT (Internet of Things) platforms. It uses the ISM 2.4 GHz band for its operation, and its operating range depends primarily on the type of application and model of the network used.
Like its previous version presented to the world in 2010, it also treats energy saving as one of the basic canons, which allows the implementation of radio communication even in the most miniaturized devices with limited power supply capacity. Thanks to full control over energy expenditure, it works well with energy harvesting systems.
Beacons, i.e. Beacons are a well-known family of miniature radio signal transmitters that can be used for identification, navigation and marketing purposes. We try to go beyond these margins, as evidenced by the constantly expanding range of our devices, which, despite the common core, are adapted to perform more and more different functions. From the simplest activities in the form of determining the user’s location based on the RSSI indicator, through the acquisition of measurement data of all types, to radio tomography enabling a new look at the detection systems of living organisms, location services and monitoring in closed rooms.
Tomography is a term derived from Greek and combines two words: section and record. It represents the field of knowledge dealing with the creation and study of cross-sections of objects thanks to various media such as ultrasonic waves, accumulated electric charge or radio waves, which are used by our devices. The effect of using such waves is a radio tomograph, thanks to which it is possible to perform non-invasive imaging of space in the 2D plane. The detection capabilities of such a tomograph are primarily focused on living organisms, but to some extent they are also able to detect inanimate matter (depending on its type).
Systems supported by this type of technology can be successfully used in in-building navigation systems, employee work recording systems or security systems without fear of violating the provisions on the protection of personal data. This is an alternative to the commonly used CCTV systems (video monitoring systems). It should be emphasized that, depending on the specific application, a radio tomograph may fulfill some of its functions only after being combined with other building systems.
