In mobile communications two main categories of antennas used are Omni and Directional antenna here I write about antenna characteristics and use. ANTENNA TYPES Omni directional antenna These antennas are mostly used in rural areas. In all horizontal direction these antennas radiate with equal power. In the vertical plane these antennas radiate uniformly across all … Read more
During detailed design, the main task is to determine the exact type and placement of the Antenna, to ensure sufficient coverage to meet the requirements. During this process, the physical properties of the Antenna must be kept in mind, as they may affect the design of the Antenna system. Many indoor Antennas are available with … Read more
Indoor solutions required? First, to analyze whether the macro cell coverage is enough. Even if the macro analysis of the project and the macro network test-drive network has sufficient coverage, additional site survey should confirm that all the target areas are covered and, more importantly, the fact that the dominant server can be found in … Read more
A DAS contains the same active components present in a DAS passive, with the addition of active devices such as amplifiers, repeaters or amplifiers bidirectional (BDAS) to amplify and / or radio signals shipping. This enables an active DAS to cover a much larger area of a passive DAS. Active distribution systems, however, are more … Read more
