    Visual line of sight exists when an imaginary straight line can be drawn between two antennas without passing through any physical obstructions. Verifying visual line of sight is the first step in planning the Nokia Wireless Router System installation. Observation points must be high enough to allow the viewer to see over ground based obstructions.

    If it is not possible to see other routers/rooftops, it may be necessary to install the router on an adjoining tall structure, or to install a mast. Nokia RoofTop™ Wireless Router Installation Guide...

  • Page 20: Selecting The Antenna Type

    Selecting the antenna type 3.4 Selecting the antenna type The Nokia Rooftop Wireless Router is supplied with an omnidirectional antenna. For very specific cases, however, it may be necessary to use a directional antenna. The following explanations describe the two types of antenna and the special circumstances in which the directional antenna may be used.
