The DVB Project has confirmed that DVB-S2X and DVB-RCS2 technologies can be used effectively not only in geostationary satellite systems, but also in modern NGSO (Non-Geosynchronous Satellite Orbit) constellations, i.e. satellites in orbits other than geostationary. The latest analysis extends previous research on LEO (Low Earth Orbit) satellites to include MEO (Medium Earth Orbit). In simulations carried out by Magister Solutions, the performance of DVB-S2X and DVB-RCS2 was compared with the 5...

The DIPOL SMART HORIZON COMBO A2270 and DIPOL SMART CITY COMBO A2050 television aerials are directional broadband aerials designed for receiving DVB-T2 in the VHF and UHF bands. The design of both models allows for the reception of multiplexes broadcast in different polarisations, meaning the antennas can be used in installations requiring simultaneous reception of signals from both frequency ranges....

Ultimode fibre-optic connectors allow for direct cable termination, without the need for an intermediate subscriber socket to protect the splice and the spare optical fibre.

DarkFighter 2.0 is an advanced image processing technology designed for round-the-clock video surveillance in challenging lighting conditions. Thanks to the use of an AI ISP (Artificial Intelligence Image Signal Processor), the technology optimises image capture parameters in real time, enabling clear, detailed and colourful images to be obtained even in very low light. DarkFighter 2.0 minimises the trade-off between night-time i...

The range of a wireless network depends on many factors. Some of them we can influence, while others are unknown. Fresnel zone is one of the most important concepts appearing in radio subjects you absolutely must be familiar with. It is the area actively involved in the transmission of radio signal energy. The shape of this area in longitudinal section is an ellipse, and in cross-section it is a circle. The radius of this circle varies along the length of the entire radio link and assumes a max...
