Introduction

The RC1244 RF Transceiver Module is a compact surface-mounted high performance module for 25 kHz narrow band FSK operation with embedded protocol. The module is completely shielded and pre-certified for operation under the European radio regulations for license-free use. The module contains additionally 16 dedicated channels for license-free use in Sweden. When used with quarter-wave antennas a line-of-sight range of 2 - 4 km can be achieved.
