  2. Coverage map - Wikipedia

    en.wikipedia.org/wiki/Coverage_map

    Typically a coverage map will indicate the area within which the user can expect to obtain good reception of the service in question using standard equipment under normal operating conditions. Additionally, the map may also separately denote supplementary service areas where good reception may be obtained but other stations may be stronger, or ...

    en.wikipedia.org/wiki/Smart_antenna

    Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.

    en.wikipedia.org/wiki/TV_and_FM_DX

    Long single-hop (900–1,500 miles or 1,400–2,400 kilometres) Sporadic E television signals tend to be more stable and relatively free of multipath images. Shorter-skip (400–800 miles or 640–1,290 kilometres) signals tend to be reflected from more than one part of the Sporadic E layer, resulting in multiple images and ghosting, with phase ...

    en.wikipedia.org/wiki/Distributed_antenna_system

    The RF node with three antennas was at the platform and another antenna near the stairs on the far side. A distributed antenna system ( DAS ) is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure.

  9. Virtual Antenna Mapping - Wikipedia

    en.wikipedia.org/wiki/Virtual_Antenna_Mapping

    Virtual Antenna Mapping (VAM) is used in wireless telecom networks. Typically when MIMO is deployed using two power Amplifier for two transmit antennae, there is a risk that both power amplifiers are not optimally used. Non-MIMO traffic would be using up to half of the available power whereas MIMO traffic could use the full power.
