· Small Size, Light Weight, Low Cost
· 7.5 µA Sleep Current Supports Battery Operation
· Timer and Event Triggered Auto-reporting Capability
· Analog, Digital and Serial I/O for Sensor Applications
· -40 to +85 oC Operating Temperature Range
· FCC and ETSI Certified for Unlicensed Operation
The WSN802G transceiver module is a low cost, robust solution for 802.11g sensor
networks. The WSN802G’s very low sleep current makes long life battery operation
practical. The WSN802G module includes analog, digital and serial I/O, providing
the flexibility and versatility needed to serve a wide range of sensor network applica-
tions. The WSN802G module is easy to integrate and is compatible with standard
802.11b/g access points.

WSN802G Antenna Connector
A U.FL miniature coaxial connector is provided on both WSN802G configurations for connection to the RFIO port.
A short U.FL coaxial cable can be used to connect the RFIO port directly to an antenna. In this case the antenna
should be mounted firmly to avoid stressing the U.FL coaxial cable due to antenna mounting flexure. Alternately,
a U.FL coaxial jumper cable can be used to connect the WSN802G module to a U.FL connector on the host cir-
cuit board. The connection between the host circuit board U.FL connector and the antenna or antenna connector
on the host circuit board should be implemented as a 50 ohm stripline. Referring to Figure 3, the width of this
stripline depends on the thickness of the circuit board between the stripline and the groundplane. For FR-4 type
circuit board materials (dielectric constant of 4.7), the width of the stripline is equal to 1.75 times the thickness of
the circuit board. Note that other circuit board traces should be spaced away from the stripline to prevent signal
coupling, as shown in Figure 4. The stripline trace should be kept short to minimize its insertion loss.
