451 +* Support peer-to-peer protocol
452 +* TCXO crystal to ensure RF performance on low temperature
453 +* Spring RF antenna
454 +* Available in different frequency LoRaWAN frequency bands.
455 +* World-wide unique OTAA keys.
456 +* AT Command via UART-TTL interface
457 +* Firmware upgradable via UART interface
458 +* Open Source Mobile App for LoRaWAN signal detect and GPS tracking.
