GAN Signal Strength Threshold IT policy rule


This rule specifies the signal strength threshold that a BlackBerry® device can use to rove in from the WAN to the GAN.

Default value

The default value is a null value. A BlackBerry device chooses a suitable value. This value might be specified by the mobile network provider.


In the WAN-preferred mode, if the signal strength of the serving cell drops below the value that you specify, a BlackBerry device uses the GAN cell if one is available.

This value is specified in Received Signal Level units, as described in the 3GPP® 5.08 8.1.4 specification:
  • 0: -111 dBm
  • 63: -48 dBm

Minimum requirements

  • Java® based BlackBerry device
  • BlackBerry® Device Software version 4.2.1
  • BlackBerry® Enterprise Server version 4.1 SP3
