💡 Why Go Dual-Frequency?
Reduce SKUs: One module for multiple countries.
Build Smarter Products: Devices that can talk on different networks.
Future-Proof: Adapt to changing network requirements via firmware.
Enhance Reliability: Switch bands if one is noisy.
⚠️ Important Notes
Antenna is Key: A single antenna for two far-apart bands is a design challenge. Performance may be a compromise.
You Control the Switch: The module doesn't auto-switch. Your firmware must manage the frequency change via SPI commands.
Certification: Getting regulatory approval for two bands is more involved.
🚀 Is This For You?
Yes, if you need: A global product footprint, a device that participates in two separate wireless networks, or maximum hardware simplification for a multi-region lineup.
No, if you need: The absolute best performance on a single, specific frequency band.
The N520AS redefines flexibility. It's not just a wireless module; it's a strategic platform for building adaptable, future-ready connected products.
