Amazon A2B User Manual 
Overview 
The Amazon A2B device is used as a tracking device for 
the GoCart containers in Amazon middle mile logistics. 
It uses various RF technologies like RFID, Bluetooth and 
Ultra-Wideband to determine the positions of the 
tracked asset. Besides that it provides additional 
functionalities like red tagging of the asset, 
temperature and orientation monitoring. The device 
has been designed to be maintenance-less and should 
be able to operate for a period of at least 5 years. 
Key Features 
○ Supports passive RFID inlay tag. 
○ Supports Bluetooth 5.1 with BLE advertising in 3 
formats: Eddystone TLM, Eddystone UID and 
Amazon A2B format. 
○ Supports the UWB channels 2 (3993.6 MHz) and 3 
(4492.8 MHz). 
○ Supports 2 defined UWB TDoA blink frame formats. 
■ Positioning Frame Format (proprietary). 
■ Telemetry Frame Format (proprietary). 
○ The UWB data frames comply with IEEE802.15.4a 
standard. 
○ Motion detection using accelerometer sensor that 
helps to increase the battery lifetime and reduce the 
UWB air-time usage. 
○ Battery lifetime of 5 years using a non-rechargeable 
battery. 
■ Battery options: 1x Li -SOCl2 3.6V battery 
(compliant with the safety regulations defined 
by IEC 60086 -4, UL 1642, UL 2054, UN38.3 or 
equivalent). 
○ Integrates a RGB LED, a multifunctional Front 
Button and extra GPIOs for connection with 
external sensors or IOs.
