Despite the rapid development of mobile networks, many users require an independent telemetry network for remote control of technological units. DCom has extensive experience in building telemetry networks for energy, water and flood protection systems. The MC13 radio telemetry unit has long been one of our important products. We have used our experience in the […]
In railway operation, technology based on the international GSM-R standard is used for voice and data communication. Compared to the conventional GSM, a number of functions are added to ensure safety, reliability and continuity of railway transport. Examples include group calls, functional addressing, and user and call priority settings. GSM-R technology uses handsets specifically designed
Giant Mountains cottage Severka 21.1.2010 Once again, one of the other very successful MikroTik trainings, where DCom presented the basic principles of WiFi operation. The program also included the measurement of the Nv2 protocol spectrum and others. Spectrum interference by other transmissions and the effect on transmission rate were measured. The whole event took place
Due to the built-in GSM-R infrastructure, communication devices are required for special traction vehicles, which must meet the requirements for minimum dimensions and simple operation. Portable device for voice communication in GSM-R networks type SVR-810R consists of GSM-R terminal SED OPH-810R , docking stations and external antennas. The basic controls, enabling circuits, are located in
Handheld panel antenna designed for the 850-890 MHz band. Devices for remote reading and data collection from measuring devices work on this frequency – water meters, thermometers, .. Compact dimensions and low weight facilitate handling and reading. With a gain of 8.7 dBi, it is an unrivaled device on the market for this band. The
Cage 15.12.2010 Further MikroTik training, where DCom presented its products (especially horizontal sector antennas and bipolar antennas). The spectrum was measured again, this time for the Nv2 protocol. Thank you for your participation. DCom wishes all its customers a pleasant and peaceful Christmas holidays and a step in the right direction until the New Year.
One of the many custom-made antennas from our production is, for example, ZZ1G8O9, it is an omnidirectional antenna for the DECT band 1880-1890MHz. The beam angle in the H plane is 360 ° and in the E plane 10 °, the gain of 9.5dBi is sufficient to cover a medium-sized area. The holder is adapted
Panel antenna for GSM-R band. The modernization of České dráhy includes the coverage of the corridor and other tracks with a GSM-R signal. DCom developed and supplied antennas for this project as well. This created competition for the well-known manufacturer of GSM antennas Kathrein. However, ZZ900MHZG2x18.5D30 is directly designed for GSM-R and thus shows better
DCom offers a wide range of antennas for the unlicensed band 2400MHz and 5600MHz as well for the 3500MHz license band. The offer is gradually expanded and adjusted according to market requirements. During production, care is taken to comply with the parameters, especially PSV, each antenna is measured and controlled. The design is designed to
Nelahozeves 15.10.2010 DCom participated in another Mikrotik training, this time held in Nelahozeves. The participation of the students exceeded all assumptions. DCom initially presented news in the field of antennas ( bipolar antennas and small sectors ). One of the main parts of the presentation was to explain the basic principle of operation of antennas.
