Chapter 1 Overview
Key Features
Power
The bridge is available in two output power versions to support international regulatory regions:
•
Regular Power—Supports 24, 23, 22, 21, 18, 15, 12 dBm output power settings. Available in the
integrated antenna and external antenna bridge configurations.
•
Low Power—Supports 16, 13, 12, 10, 9, 8, 7, 4 dBm output power settings. Available only in the
integrated antenna bridge configuration for use in international regulatory regions.
The bridge receives inline power from the Cisco Aironet Power Injector LR (hereafter called the
power
injector
). Dual-coax cables are used to provide Ethernet data and power from the power injector to the
bridge. The power injector is an external unit designed for operation in a sheltered environment, such as
inside a building. The power injector also functions as an Ethernet repeater by connecting to a
Category 5 LAN backbone and using the dual-coax cable interface to the bridge.
The power injector uses an external 48-VDC power module and after detecting the presence of the
bridge, injects the DC voltage into the dual-coax cables to power the bridge.
Note
The power injector and the power module should not be placed in an outdoor unprotected environment.
External Antenna
The bridge is available with an N-type RF connector on the front of the unit (see
Figure 1-1
) for an
external 5.8-GHz antenna. The supported external antennas connect to the bridge antenna connector
using the antenna’s 4.9-ft (1.5-m) coax cable.
•
9-dBi omnidirectional external antenna with vertical polarization
•
9.5-dBi sector external antenna
•
28-dBi dish external antenna
Note
To meet regulatory restrictions, the external antenna bridge configuration and the external antenna must
be professionally installed.
Note
Some international regulatory regions may restrict the use of external antennas.
