Introduction The installation of a wireless network requires some additional planning over a wired network. This planning includes RF (Radio Frequency) path planning, site preparation, and installation of outdoor components such as outdoor units, antennas, lightning protection devices, and cabling suitable for outdoor conditions.

  • Page 245 ZyAIR B-5000 User’s Guide Where either of these conditions exists, shorter paths and adequate clearances are recommended. Wind Any system components mounted outdoors will be subject to the effect of wind. It is important to know the direction and velocity of the wind common to the site. The mounting structure must be able to withstand these forces as well as protect against damage to the wireless bridge components.

  • Page 246: Antenna Characteristics

    ZyAIR B-5000 User’s Guide Co-Channel and Adjacent Channel Interference Co-channel interference results when another RF link is using the same channel frequency. Adjacent-channel interference results when another RF link is using an adjacent channel frequency. A spectrum analyzer can be used to determine if there is any strong signals present at the site and determine how close they are to the desired frequency.

  • Page 247: Antenna Polarization

    ZyAIR B-5000 User’s Guide Antenna gain is sometimes specified in dBi, which is how much the antenna increases the signal power compared to using an isotropic antenna. An isotropic antenna is a theoretical perfect antenna that sends out radio signals equally well in all directions. dBi represents the true gain that the antenna provides.
  • Page 248 ZyAIR B-5000 User’s Guide A signal degrades as it moves through space. The longer the path, the more loss it experiences. This free-space path loss is a factor in calculating the link viability. Free-space path loss is easily calculated for miles or kilometers.
