RF transceiver modules enable simultaneous transmission and reception of radio signals between two or more nodes. WIT2492M is a RF transceiver module widely used in many applications, such as wireless data communication, mobile communication, and wireless sensor networks. The WIT2492M module operates in the 918-928 MHz ISM band and utilizes over-the-air communications with embedded protocols.

Features

The WIT2492M module is a highly integrated, low-power, low-cost single chip transceiver optimized for ISM systems. It has a simple, flexible architecture that supports frequency hopping, diversity transmission, and direct sequence spread spectrum (DSSS) modulation schemes with a transmission power up to +14 dBm. It also features data rate up to 2 Mbps and meets or exceeds the requirements from the standards in the intended applications. Its main features include:

• Supports operation in 918-928 MHz ISM band
• Data rate up to 2 Mbps
• Transmitting power up to +14 dBm
• Low current consumption
• Low RX background noise
• Highly integrated on-board TCP/IP stack
• Supports frequency hopping and direct sequence spread spectrum modulation schemes
• Small PCB size while incorporating all necessary functions for RF signal transmissions

Applications

The WIT2492M is suitable for a wide variety of applications including industrial automation, home and building control, wireless sensor networks, wireless power transfer, remote control, and audio systems. It can also be used in wireless telemetry and data links, noting and tracking systems, intelligent transportation systems, and mesh networks.

Working Principle

The working principle of the WIT2492M module is based on frequency hopping and direct sequence spread spectrum (DSSS) modulation schemes. In frequency hopping, the radio frequencies used are continuously changed, making it virtually impossible for an eavesdropper to track the transmissions. The DSSS modulation scheme makes the data transmission immune to continuous-wave interference, which makes it much more reliable than other modulation techniques. In addition, the WIT2492M has built-in algorithms that enable the module to automatically select the best signal possible among the multiple channels.

To further improve the signal reception accuracy of the module, it uses a combination of intelligent techniques such as predictive coding, data redundancy, error correction codes and error detection codes. All these features make the WIT2492M an ideal solution for applications requiring robust, reliable, and secure wireless data transmissions.
