  • Page 77: Antenna Properties And Considerations

    Antenna properties The external antennas supported by the Nortel WLAN 2300 system are passive devices. A key attribute included in their design is that they are DC-coupled to the output of the WLAN access point to enable the software to detect their presence and direct the energy out their aperture rather than through the internal antennas mounted within the access point housing.
  • Page 78 When transmitting, the presence of side and back lobes may cause interference to other nearby access points, and when receiving, they may allow interference into the access point from surrounding WLANs or rogue devices.
  • Page 79 It is assumed that nothing in the propagation path causes the signal polarization to change, which is known as polarization distortion. Nortel WLAN 2300 Series Outdoor Solution Guide...
  • Page 80 With linearly polarized antennas, the polarization of each antenna must be of the same orientation to achieve maximum energy transfer between the two antennas. If the two linearly polarized antennas are not identically oriented, there will be a reduction in energy transfer due to polarization mismatch. The table below provides a summary of polarization mismatch loss between two linearly polarized antennas that do not have the same angular orientation.

  • Page 81: Rf Propagation And Path Loss

    Path loss is encountered when an RF signal propagates through the air. The relative signal strength of the propagating wave diminishes as a function of distance traveled from the transmitting antenna. The free space propagation loss factor is described by the following equation, Nortel WLAN 2300 Series Outdoor Solution Guide...
