User Manual Chapter 2

Chapter 2 - 2
a. Maximize antenna performance by keeping clear of obstructions.
b. Minimize visual impact if possible.
c. RF cable run and identify a building access point.
3. Perform a radio test to confirm a link to the ISP.
a. As close as possible to the selected antenna location, set up a test antenna of the same type
recommended by the network manager.
b. Connect the antenna to the test IDU. Using a GPS receiver or magnetic compass, point the
antenna toward the bearing of the base station.
c. Power up the test IDU and check the front panel LEDs. The PWR and CPU LEDs should be lit,
and both FAULT LEDs should be off. If all three RADIO status LEDs (RX, TX and LINK) are lit,
the link is good. If not, try any or all of the following;
1. Slowly rotate the antenna to maximize signal strength.
2. Move the antenna location to avoid interference or obstructions. This may include raising
the antenna height.
3. Perform the Antenna Null Steering procedure (see appendix I)
4. Try to establish a link to a different base station, if available.
5. Try a higher gain antenna type.
d. Once a link is established, contact the network manager to perform a relay to client "ping" test. If
successful, this indicates a good subscriber site with a suitable antenna location. Record the
successful antenna location, type and bearing. If a link and "ping" test cannot be established,
another antenna location may be needed, or the subscriber may have to wait for a closer base
station to be established.
4. Map out the RF cable run. Identify drilling locations, conduit runs, drop ceilings, etc. as needed.
Determine the minimum length of cable required. Select the appropriate cable part number in accordance
with Table 2-1.
REQUIRED TOOLS AND EQUIPMENT:
The CPE installer should have the following tools and equipment:
• Site Survey Equipment – Test IDU, each of three antenna types (high gain reflector, high and low gain panels),
connecting cables, GPS locator or magnetic compass, cell phone or radio, electrical extension cord.
• Antenna Installation Equipment - TBD
• Site Configuration Equipment - laptop computer or PC with terminal emulation application, RS-232 serial cable.
