Frequency Stability Statement

The 40 MHz crystal provides the core clock for the AR2313 and AR5112. This crystal
is attached to the AR5112, witch then internally forms an oscillator. The AR5112
then provides the output of the oscillator to its internal frequency synthesizer, and
to the AR2313.

The maximum frequency tolerance allowed by the IEEE 802.11 standard is ±20
ppm. Therefore, the crystal device needs to meet this requirement over all
operating conditions. Atheros recommends a crystal device with an overall
tolerance of 18 ppm that includes initial tolerance, tolerance over operating
temperature range, and aging tolerance.

The crystal device used in the Reference Design is calibrated at 15 pF load. When
designing the crystal circuit, care should be taken to include the board stray and
other capacitances, such as those inherent with the oscillator circuits, in the overall
calculation of the load capacitance.

Airaya – Fast and affordable outdoor wireless bridges

Before you mount the AI108-4958-N, AI108-4958-1, or AI108-SU
to a fixed location, consider the following requirements to
determine the optimal placement:

The RF cable between the AI108-4958-N, AI108-4958-1, or AI108-SU and
the antenna should be as short as possible without putting too much
stress on the connectors at the bridge and antenna. The RF cable
attenuates (reduces) the radio signal and will reduce the effective range
of your wireless link.

The cable length from the Ethernet network port to the AI108-4958-N,
AI108-4958-1, or AI108-SU must not exceed 328 ft (100 meters).

Placement must allow for easy access to disconnect the bridge unit from
the AC power outlet if necessary.

Follow these steps to install the AI108-4958-N, AI108-4958-1, or AI108­SU indoor bridge:

1. Connect the Ethernet cable – The AI108-4 and AI108-N should be
connected to a 10/100Mbps Ethernet network through a switch or
router. Alternatively, a computer can be directly connected to the
bridge using an Ethernet cross-over cable. Connect to the RJ-45
connector socket on the back panel of the bridge with 5 UTP
Ethernet cable and an RJ-45 connector.

2. Connect the power adapter cable to the 5V, 2A DC power socket on
the rear panel, and plug the power adapter into the wall outlet.

Warning: Use only the power adapter supplied with the bridge in
order to prevent damage and void warranty.

3. Refer to the section above on LED status indicators to verify the
unit is powered on and functioning properly.

4. Connect the optional
lightning arrestor and
jumper cable assembly

Installing and Visually Aligning Outdoor Antenna

To ensure maximum performance and stability of your wireless link, it is
crucial that you determine the right locations for the outdoor antennas
based on the following criteria:

• A good signal path, ideally with visual line of sight and

adequate Fresnel clearance between bridges

• Minimal distance between bridges

• Minimal reflections from other objects.

Figure 6. If using 23 dBi directional antennas supplied by AIRAYA, mast
mounting of the external antennas can be accomplished using the included
mounting brackets with full vertical and horizontal adjustment.

NOTE

When wall mounting the antenna to the side of a structure, you will not need the back
portion of the mounting bracket. Use screw-in anchors, molly bolts, or pan-head screws to
attach antenna mounting bracket to side of structure.

- 16 -

Airaya – Fast and affordable outdoor wireless bridges

Follow these steps to install and visually align outdoor antennas:

1. Attach the antenna to a mast or side of a building using the included
bracket.

2. Align the outdoor antenna horizontally: Loosen the horizontal
adjustment bolt and nut to visually aim the antenna at the remote
bridge. Set the appropriate horizontal angle and tighten the horizontal
adjustment bolt and nut so that the angle is locked in place.

3. Align the outdoor antenna vertically: Loosen the vertical adjustment
bolt and nut on the mounting bracket and point the antenna towards
the remote end point. Set the appropriate elevation angle and tighten
the alignment bolts so that the angle is locked in place.

4. Secure the cable along the mast between the outdoor antenna and the
indoor bridge inside your building. Note: We recommend that you
secure the entire cable to the mast at 10-foot intervals.

5. Repeat steps one through four for each remote location outdoor
antenna.

6. Use the real-time Signal Strength Monitor to fine-tune received signal
strength (RSSi) between bridges. This tool is designed to maximize the
throughput of your new WirelessGRID link by providing the highest
possible signal strength across a wireless path. See the section on
“Antenna Alignment and Link Monitoring Tool” for instructions.

TIP

If this is your first installation of an AIRAYA link, AIRAYA recommends that
you perform the bench test procedure in Appendix A before deploying the
product. This will ensure that bridges are functioning properly and fully
configured, and will allow you to become familiar with the tools for aligning
antennas and optimizing throughput before you get into the field.
