Installation Steps for the SPEEDLAN 9202/SPEEDLAN 9203
Generally, these routers follow the same general installation steps. Some installation
instructions are specific to customers who purchased Installation Kits from P-Com. To
view a diagram of the installation listed below, see Figure 2-9 on page 2-21.
If you are having trouble and need a full site installation, contact P-Com for services
and fees.
Antenna Selection Tip: Use a high-gain omni or sectoral antenna for a base station
(SPEEDLAN 9203), and use a grid or directional antenna for a CPE or point-to-point
router (SPEEDLAN 9202).
To install your router with an external antenna, do the following:
Step 1.Verifying Line-of-Sight
Before installing the antenna and router, make sure a clear line-of-sight exists between
the two points. Line-of-sight can be defined as each antenna clearly seeing the other
antenna, and seeing the remote locations when viewing from the central base location.
Be sure to look at the center of origin of the transmission (i.e., the middle of the
antenna). Repeat this procedure from the remote location. Any disruption of the signal
path due to trees, building, or any other obstructions may cause the link to function
incorrectly. Make sure at least 60 percent of the RF signal is unobstructed by any path
blockages.
