WI.232FHSS-250
TM
FCC prescanned Wireless Module
915 MHz, 152.34 kbit/sec.
DESCRIPTION
The Wi.232FHSS-250
TM
module combines a state-of-the art low power wireless
transceiver with a powerful multipoint-to-multipoint frequency protocol control-
ler to form a complete wireless communication solution. With a simple UART
interface, a 125dB link budget, and very low power operation modes, the
Wi.232FHSS-250
TM
module is excellent for AMR, RFID, Home Automation, and
any other application requiring long range (7 miles LOS, 1500 feet indoors) and
long battery life.
The module can operate as a transparent wire replacement solution; it can also
operate in a peer-to-peer networked mode that supports node addressing and
assured delivery. The module is designed to be totally transparent. Data is
validated using an internally generated CRC-16 and encoded using a proprietary
algorithm. Multiple modules can operate on the same channel because of the
built-in carrier-sense-multiple-access (CSMA) protocol.
A wide range of data rates can be supported, allowing the designer to tune the
module’s performance to meet the application’s throughput and range require-
ments. The RF data rate is programmed to optimally match the UART data
rate, which can be programmed from 2.4 to 115.2 kbit/second. The maximum
RF data rate is 152.34kbit/second.
The Wi.232FHSS-250
TM
module employs frequency hopping spread spectrum
modulation. There are thirty-two separate hopping channels in a hopping table,
and the designer can program the module to use one of six hopping sequences.
These techniques allow the Wi.232FHSS-250
TM
to operate co-located networks
without interference. The Wi.232FHSS-250
TM
is a very cost effective solution for
any wireless application where range, cost, size, and power consumption are
key design issues.
