Planning the Physical Layout
Before you install the units, you must determine the physical locations for each
component of your 300-24 system. When you plan the physical layout, you will need to:
• use a GPS, map, or other distance measurement method to determine the physical
distance between each unit
You must have a professional installer assess and calculate the following:
• the antenna mast height requirements and fade margins
• the cable requirements including routing, between antenna and unit
• the fade margin to determine the reliability of your wireless link
• the weatherproofing requirements
Determining the Physical Distance Between Sites
Before you install the units, use a mapping method to determine the distance between your
sites. When you determine the distance, you must check the radio path to identify any
obstructions in the site path between radio locations. You can contact a Wi-LAN
applications engineer to confirm that you have planned an effective radio layout. See
Customer Support on page 3 for more information about contacting Wi-LAN.
Working with Antennas
If you are installing the unit in an indoor setting, the antenna packaged with the unit will
be sufficient for indoor wireless communications. If you are installing the unit in an
outdoor location, a professional installer must calculate the required mast height to ensure
effective communication between your radio links. When installing an outdoor antenna,
the professional installer should consider:
• the required height of the antenna to ensure a clear line-of-site between the RF links
• regulatory restrictions, such as height, on antenna mast usage in the identified location
• obtaining permission from building owners if you intend to install your antenna on a
rooftop
• potential wind load and ice loading impact on the antenna
• grounding requirements. The antenna must be properly grounded for lightening in
accordance with the relevant electrical code for the installation location.
See Working with Antenna Gain on page 19 or see the 300-24 Product Specification for
more information about installing and selecting antennas in outdoor locations.
Due to the high
frequency and low
output powers
permitted in the ISM
band, no
obstructions can be
tolerated between
two antennas.
You should use
lightening arrestors
to ground your
outdoor antenna,
cables, and support
structures.
