#### **Cons**
1. **Limited Indoor Performance** The 900 MHz frequency is **highly attenuated by walls, trees, and foliage**, making it less effective for indoor or urban environments compared to 2.4 GHz (Wi-Fi) or 868 MHz (EU) modules. Outdoor or line-of-sight applications are best suited.
2. **Higher Cost Compared to 2.4 GHz Modules** The XBee Pro 900 is more expensive than standard XBee S2C or Zigbee modules, which may be overkill for short-range applications.
3. **Licensing Restrictions in Some Regions** While the 900 MHz band is **license-exempt in the U.S. and Canada**, some countries (e.g., parts of Europe) have **strict power limits or require licensing** for high-power transmissions. Always verify local regulations before deployment.
4. **Sensitivity to Interference** The 900 MHz band can be prone to **radio interference from other devices, weather conditions (rain fade), or industrial machinery**, potentially reducing reliability in noisy environments.
5. **Limited Global Availability of Antennas** While the XBP09-DPSIT-156 6A is a standard wire antenna, **custom or region-specific antennas** may require additional sourcing, increasing procurement complexity.
6. **No Built-in Wi-Fi or Cellular Connectivity** Unlike some competing modules (e.g., LoRa-based ones), the XBee Pro 900 does **not support Wi-Fi or cellular backhaul**, meaning you ll need a separate gateway for cloud connectivity.
7. **Higher Power Draw in Active Mode** While sleep current is low, **continuous transmission at high power (150 mW) consumes more current** than low-power alternatives, which may shorten battery life in portable applications.
8. **Learning Curve for Advanced Features** While basic serial communication is simple, **mesh networking, routing, and advanced security configurations** require familiarity with Digi s API and documentation, which may be a barrier for beginners.
9. **No Built-in GPS or Location Services** Unlike some LoRa or cellular modules, the XBee Pro 900 does **not include GPS**, meaning location tracking requires an external GPS module.
10. **Limited Commercial Support for Newer Alternatives** Newer **LoRa-based modules (e.g., Semtech SX1276)** or **sub-1 GHz Zigbee** options may offer better range, lower power, and broader ecosystem support in some applications, depending on use case.
