WSN802G Hardware
The WSN802G operates in the international 2.4 GHz
ISM band over the frequency range of 2401-2474 MHz,
with a nominal RF output power of 10 mW. The WSN-
802G supports two standard 802.11g RF data rates, 1
and 2 Mb/s.
The WSN802G transceiver module provides a variety of
hardware interfaces. There are two serial interfaces, one
for data and a second for diagnostics. The data port sup-
ports standard serial baud rates from 1.2 to 921.6 kb/s,
and the diagnostic port operates at a fixed baud rate of
9.6 kb/s. Hardware flow control is not currently imple-
mented on either serial port.
The WSN802G includes two 10-bit ADC inputs, a 16-bit
PWM (DAC) output, two digital inputs and two digital out-
puts to support sensor network applications.
The WSN802G is available in two mounting configura-
tions. The WSN802GC is designed for solder reflow
mounting, and the WSN802GP is designed for plug-in
connector mounting.

WSN802G Firmware
The major firmware components in the WSN802G in-
clude the 802.11g stack and the application protocol.
The WSN802G acts as a UDP client to a data and/or
sensor application running on a network server.
The application protocol supports three operating modes:
(1) sleeping sensor node with timer or interrupt auto-
reporting, (2) sleeping serial data node with timer or inter-
rupt wake-up and (3) always on sensor or serial data
node with auto-reporting. Modes 1 and 2 take full advan-
tage of the very low sleep current capability of the
WSN802G. The module sleeps unless the WAKE_IN
input is asserted or the AutoReport timer fires. A Wake-
Timeout timer is provided to hold the module awake for
a configurable period. The WakeTimout timer is held in
reset as long as WAKE_IN is asserted, serial data is
being received, an RF packet is being sent or received,
or if the module is uncommissioned.
The WSN802G asserts WAKE_OUT whenever it is
awake to notify its external host. The module also sends
an I/O status report automatically each time WAKE_IN is
asserted, and/or each time the AutoReport timer fires.
