Amazon Sidewalk is a secure, shared community network that leverages Sidewalk‑enabled Amazon Echo and Ring devices as gateways. It extends connectivity for low‑bandwidth IoT products far beyond the limits of standard home Wi‑Fi. The network operates over Bluetooth® LE, Sub‑GHz FSK, and Sub‑GHz CSS/LoRa, enabling both short‑range and long‑range communication. Bluetooth® LE handles nearby device links, while LoRa and FSK at 900MHz frequencies provide extended coverage.
Sidewalk Over Bluetooth® LE
Designed for the next generation of Amazon Sidewalk-enabled IoT devices, the TL3238E1 brings together advanced Bluetooth® connectivity, flexible multi-protocol operation and ultra-low-power performance for reliable, long-lasting connected products.
Sidewalk over Sub-GHz
Our BLE SoCs work with third-party Sub-GHz SoCs to support flexible BLE, FSK and LoRa connectivity, enabling reliable medium- to long-range communication through Amazon Sidewalk gateways.
