Welcome to Purple Support

Asset Tracking Hardware

  • Updated

Pole Star

Pole Star manufacture BLE tags that are designed to be fixed to assets. These will emit RF signals.

Pole Star will assist with the placement of BLE Listeners, with Purple supporting where required. Facilities support is necessary to enable the implementation of listeners. 

BLE listeners measure the received signal strength and send the data to Pole Star's NAO Cloud which computes the locations. This allows visibility for the real time location of assets.

BLE Packets


Default Battery Life

5+ years (850ms interval, 0 dBm, 20°C) with 1 battery

10+ years (850ms interval, 0 dBm, 20°C) with 2 batteries 


Bluetooth 5.0. Works with Bluetooth Smart 4.0+ devices

Battery Type

AA/LR6, x1 or x2 depending on configuration. Batteries are non-rechargeable Lithium (Li-SoCl2) 3.6V 2500 mAh. These are replaceable

Power supply

5.0V DC - 1A (micro-USB) (wall plug USB power supply available), or Power Over Ethernet (PoE 802.3af). If using PoE the WiFi connection doesn't need to be powered. If using the mains, there is a requirement to connect to the WiFi on the site. 

Max Range

> 100m outdoor

25m indoor, variable








30g without batteries, 70g with two batteries

IP Connectivity

10/100 Ethernet WAN, or 802.11 b/g/n 2.4 GHz Wi-Fi


Additional requirements for WiFi connectivity

  • 802.11 b/g/n WiFi network operating at 2.4 GHz. 5 GHz WiFi networks are not supported
  • WiFi authentication schemes based on pre-shared keys are supported (e.g. WPA(2) Personal, and WPA2 Enterprise using PEAP MSCHAPv2 protocol)
  • SSID visibility can be disabled for security reasons after the initial connection. It is only required to connect to the Wifi

DHCP support is required on the network side. 



The recommended typical height of the wall/ceiling mount is 2.5m (6m maximum).

Screws and expanding plugs are provided, along with a drill template sheet. Adhesive tape can be used for temporary setups, though this isn't provided alongside the hardware. 

Pole Star will assist with the placement of BLE Listeners. Facilities support will be required to enable the implementation of listeners.
