3.0 System Description
The Wireless Networks Falcon Packet Radio is used in a wireless local area network, operating
in the 450 - 470 MHz frequency band. The installed radio consists of a stand-alone countertop
radio, cables to access Ethernet and data lines, AC wall transformer, antenna, and coax cable to
the antenna. The unit is powered by an AC wall transformer, which converts AC mains (90 –
240 VAC) to DC voltage to power the radio. Data transmission capability is 19.2 kbps. Radio is
operated in half-duplex mode, and data is transmitted in packets. Front panel contains
connectors to AC transformer, Ethernet, data lines; front panel also contains indicator lights
(LEDs). Rear panel contains connector to antenna. This radio is licensed by the FCC under
parts 2 and 90, and meets FCC part 15.
There are two main physical/functional blocks, an RF module and a digital board. The RF
module is an off the shelf half duplex UHF RF link, capable of 2W of output power. The digital
board is a printed circuit board that provides the remainder of the hardware functionality (CPU,
peripherals, internal power supplies, etc.). Both the digital board and RF module reside in a
metallic enclosure, to provide electromagnetic compatibility. With the exception of the antenna
connector, the digitial board provides all other connections to the outside of the enclosure.
The Falcon Packet Radio operates in the 450 – 470 MHz frequency band and is used within a
local area wireless network. Synthesized RF Channels are selectable in the field, and can be
changed by instructions generated within the network. RF power output is fixed. The network
consists of individual user sites and a hub which gathers all transmitted information, monitors
activity, and generates instructions. Both of these functions utilize the same hardware.

7.0 Installation
Installation of the Falcon Packet Radio should be near an AC outlet with enough distance to use
provided AC wall transformer. When utilizing the Ethernet capability, the unit should be close
enough to Ethernet data port for easy cabling. Installation is not permanent – this is a
countertop unit that is easy to relocate. No tools are required for installation.
Antenna is to be connected by a 22-foot coax cable from the rear panel of the Falcon Packet
Radio.
Connect AC wall transformer to DC input of radio making sure that jack seats fully in mating
connector; connect other end to AC wall outlet. Connect BNC cable connector from antenna to
BNC connector on rear panel, making sure that connector locks into place. When connecting
serial ports (RJ11) or Ethernet port (RJ45) be sure that connector clicks into place.
Upon power-up, unit will perform self-tests.
This unit to be installed only by properly trained professionals, in accordance with FCC rules and
regulations.
