Airaya – Fast and affordable outdoor wireless bridges
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.
Remote Power
Power Over Ethernet is an integral part of the WirelessGRID bridge. The
injector is capable of providing power at the full distance specified by the
IEEE 802.3 Ethernet specification (100 meters).
