This application note explains how to configure the CC1101 transceiver and MSP430 MCU to create a modem compliant with the Wireless MBUS standard.
The document describes a reference implementation that combines the CC1101 low‑power transceiver with the ultra‑low‑power MSP430 microcontroller to meet the Wireless MBUS specifications for meter reading. It covers both physical‑layer requirements (frequency band, modulation, carrier frequency, sensitivity) and data‑link layer details such as packet format, CRC, and synchronization.
Technical sections include tables of RF parameters for Radio Link A and B, register settings for the CC1101, and performance results like receiver sensitivity and data‑rate drift. Appendices provide the full register configuration for both links, and a disclaimer outlines TI’s liability and usage terms.
| Frequency band (Radio Link A) | 868.0‑868.6 MHz |
|---|---|
| Modulation | 2‑FSK |
| Typical carrier frequency (Radio Link A) | 868.3 MHz |
| Receiver sensitivity (BER <10⁻²) | -105 dBm |
The typical carrier frequency for Radio Link A is 868.3 MHz.
Both Radio Link A and B use 2‑FSK modulation.
The required receiver sensitivity is –105 dBm for a BER less than 10⁻².
