    What is a mast?

    Radio base stations are commonly called masts. The terms are used interchangeably, but they are in fact two different things.
    A mast is a freestanding structure (the same ...

    Knowing, in advance of the introduction of a service, what the propagation conditions are going to be is a great advantage in planning a radio system and determining the coverage and the grade of service ...

    Rayleigh fading

    Rayleigh fading is the name given to the form of fading that is often experienced in an environment where there is a large number of reflections present. The Rayleigh fading model ...

    Multipath fading

    Antenna directivity and gain

    RF antennas or aerials do not radiate equally in all directions. It is found that any realisable RF antenna design will radiate more in some directions than others. ...

    Radio signals are affected in many ways by objects in their path and by the media through which they travel. This means that radio signal propagation is of vital importance to anyone designing or operating ...

    Multipath propagation

    Multipath propagation is a fact of life in any terrestrial radio scenario. While the direct or line of sight path is normally the main wanted signal, a radio receiver ...

    Reflection, Refraction, Diffraction

    As electromagnetic waves, and in this case, radio signals travel, they interact with objects and the media in which they travel. As they do this the ...

    Electromagnetic waves

    Electromagnetic waves and the electromagnetic spectrum are at the very core of radio signal propagation, and radio technology as a whole. While the mathematics ...

    Base stations and wireless technologies

    Mobile telephony is now commonplace around the world. This wireless technology relies upon an extensive network of fixed antennas, or base stations, ...

    RF Coax Cable Connectors

    Coax cable connectors, often called RF connectors are in widespread use. Wherever radio frequency or RF connections need to be made there is the possibility ...
