Features and Functions
Relay of radio communications
• To/from wireless sensors (downlink)
• To/from access point (uplink)
• To/from another repeater (uplink or downlink)
Extension of range and coverage of the access point
• Tandem operation – one repeater and its supported
sensors can communicate with another repeater and
then to the access point
• Maximum single-hop range of ~2000 feet (610 meters)
from supporting access point or repeater with the Long
Range External Antenna
• Maximum single-hop range of ~300 feet (91 meters)
from sensors with Long Range External Antenna
Radio signal quality measurements (of each link to
wireless sensors or tandem repeater)
• Receive Signal Strength Indicator (RSSI, in dBm)
•Link Quality Index (LQI, gure of merit 40-99)
Enclosure
• Robust protection against the environment
Simple installation
• Any roadside location that provides adequate height
and line of sight to sensors and the access point or
repeater
• Direct connection to the power source
No calibration or adjustment required
Firmware upgrades over-the-air from access point
FlexNode Line Powered Radio (NA)
The Sensys Networks Repeater. In cases where installed
Sensys Networks wireless sensors are out of range of the nearest
access point, one or more Sensys Networks repeaters can be used
to provide a two-way relay between the out of range sensors and
the access point. A repeater is pole mounted by the roadside and
is positioned so that both the sensors and the tandem repeater or
access point are within view and within range.
The Sensys Networks FlexNode Line Powered Radio is
a single pole-mounted unit. The FlexNode Line Powered Radio
includes no battery and is powered by a continuous 12-24 VDC
power source. The FlexNode Line Powered Radio is housed in a
robust enclosure that provides excellent protection against
outside environment.
The FlexNode Line Powered Radio has a connector for an
external antenna to provide for greater flexibility in providing a
two-way relay between sensors and the access point.
Antenna options. The optional external antenna connects to
the FlexNode Line Powered Radio via a coaxial cable. The
external antenna allows the repeater to be aimed in two
directions simultaneously utilizing a pole located between the
sensor and access point.
Two types of external antenna are supported: (i) the FLEX-
ANT-1 with the same RF range as the internal antenna and (ii)
the FLEX-ANT-2 with Long Range RF range. The FlexNode
Line Powered Radio can also operate without an external
antenna.

Compliance
EMC •Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in

reception, which can be determined by turning
•the equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
•—Reorient or relocate the receiving antenna.
•—Increase the separation between the equipment and receiver.
•—Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
•—Consult the dealer or an experienced radio/TV technician for help.
