The new Wi.232DTS-FCC is an FCC-approved version of the Wi.232DTS module. This new module allows you to build robust, high-performance wireless products without having to obtain FCC approval.

The module combines a high-performance wireless DTS spread-spectrum transceiver, based on the SemTech XE1203F, with a protocol controller to create a transparent wireless solution for wire replacement applications. The module is designed to be a direct replacement for RS-232/422/485 transceiver ICs and wiring. It supports power-sensitive, feature-rich applications such as automated meter reading, home automation, and active RFID.

The module contains a true MAC layer and operates in two power modes. In High Power mode, the transmit power is up to 11 dBm, the maximum RF data rate is 152.34 kbps, and 32 channels are supported. In Low Power mode, the transmit power is 0 dBm, the maximum RF data rate is 38.4 kbps, and 81 channels are supported.

With receiver sensitivity of –110 dBm at 4.8 kbps, a pair of Wi.232 modules can communicate over distances of 500¢ to 800¢ indoors and 1,500¢ to 2,500¢ outdoors.

The Wi.232DTS-FCC module has been pre-certified with three different antennas to accommodate different applications. A helical antenna allows the smallest footprint, while a half-wave antenna provides the best range performance. The module is also certified to work with a quarter-wave whip antenna.

A development kit that includes RS-232 and USB interfaces, battery and wall power supplies, debug ports and connectors, and a prototyping area is available.

The Wi.232DTS-FCC costs $64 in single quantities.
