Gateway Device Mapping- BLE

The following parameters are ‘guides’ for Gateway positioning for site installation and configuration.

KAS recommended the following parameters but can not guarantee the performance due to each sites specific nature:

Example layout:


BLE Gateway:

  • The number of devices: max 15 locks to 1 gateway, recommended 10 locks to 1 gateway.
  • Working radius: max 10 m (-90 RSSI) radial working distance, recommended 6 m (-85 RSSI) radial working distance
  • Recommended working BLE signal strength; max -40 RSSI, min -90 RSSI (Absolute max -95 RSSI)
  • WIFI signal: connect to any active WIFI network using WIFI name and WIFI password. The gateway must be in strong WIFI network range
  • Frequency: 2.4 GHz (BLE, WIFI)
  • Power: 5V Power adapter (supplied)

*Use these as a ‘guide’ only. Parameters are tested by KAS.



  • Distance is an approximate calculation from lock signal strength. The distances stated on this page are based on line-of-sight with no penetration or object interference, unless specified.
  • If the gateway is mapped to a lock to travel around corners you will need to reduce the working distance because signal strength will drop around corners.
  • WIFI signal (Gateway -> Internet) is quite an important parameter. Don’t forget to consider the gateway position relative to the building WIFI router:
    • Gateway -> Lock
    • Gateway -> WIFI router
  • If the WIFI signal to the gateway is poor, the gateway will not perform well.
