Hardware Description

Ethernet Compatibility

The AIRAYA WirelessGRID wireless bridge can be attached directly to
10BASE-T/100BASE-TX (twisted-pair) Ethernet LAN segments. These
segments must conform to the IEEE 802.3 specification.

The WirelessGRID bridge functions as an Ethernet node and performs
bridging by moving packets from a network in one building to a network in
another building.

Radio Characteristics

The WirelessGRID bridge utilizes a radio modulation technique known as
Orthogonal Frequency Division Multiplexing (OFDM) that operates in the 5
GHz Unlicensed National Information Infrastructure (U-NII) band. Data is
transmitted over a half-duplex radio channel at speeds of up to 108 Mbps.

Antenna Type

The outdoor version of the WirelessGRID bridge uses an integrated 23 dBi
panel antenna to achieve a maximum operating range of 7.5 miles under
FCC rules in the 5.8 GHz band. Range in the 5.25 to 5.35 GHz and
ETSI/ITU 5.45 bands will vary based on power output and EIRP limitations,
and local regulatory domain requirements. Please contact AIRAYA for
additional antenna options.

Enclosure

The molded fiberglass polyester enclosure of WirelessGRID base stations
and repeaters, and the metal enclosure of the WirelessGRID ODU have
been designed for maximum durability for outdoor use in a range of
weather conditions. They is watertight and meets NEMA/EEMAC Type 4,
4X, 12, and 13 specifications.

Cabling

The WirelessGRID bridge includes a Category 5e cable designed for
outdoor applications. It supports DC Power Over Ethernet for easy
installation.

System Requirements

Before installing the WirelessGRID bridge, be sure you have the following
items on-hand:

 An AC power outlet (100 to 240 V, 50 to 60 Hz) to supply power to

the indoor injector units on both sides of the wireless link

 An outdoor unit mast with a 1 to 6 inch (25.4 to 152.4 mm)

diameter

 An available RJ-45 (UTP) port on a 10/100 Mbps Ethernet switch or

router

 Web browser for software configuration

The WirelessGRID bridge has been designed to withstand normal handling
procedures, but reasonable precautions should be taken during
installation, particularly with regard to static discharge.

• Make sure that you are adequately grounded by touching the bare

metal surface on the back of a computer or networking device
before installing the indoor and outdoor units.

• Avoid moving around the work area in order to eliminate static

charge buildup.

• If possible, do not work on a carpeted area.

Installing and Visually Aligning Outdoor Units

To ensure maximum performance and stability of your wireless link, it is
crucial that you determine the right locations for the outdoor
units/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, pole mast mounting of
the external antennas can be
accomplished using the included
mounting brackets with full
vertical and horizontal
adjustment.

Follow these steps to install and visually align outdoor units/antennas:

1. Attach the outdoor unit/antenna to a mast using the included pole­mount bracket.

2. Align the antenna horizontally: Loosen the horizontal adjustment bolt
and nut to visually aim the outdoor unit/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 enclosure/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.

Airaya – Fast and affordable outdoor wireless bridges

4. Secure the cable along the mast between the outdoor
enclosure/antenna and the indoor unit 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 outdoor unit or antenna at a
remote location.

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.
