radiotronix WI.232FHSS-250TM FCC prescanned Wireless Module 915 MHz, 152.34 kbit/sec. DESCRIPTION The Wi.232FHSS-250TM module combines a state-of-the art low power wireless transceiver with a powerful multipoint-to-multipoint frequency protocol controller 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-250TM 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 requirements. 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-250TM 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-250TM to operate co-located networks without interference. The Wi.232FHSS-250TM is a very cost effective solution for any wireless application where range, cost, size, and power consumption are key design issues.
