Understanding the Relationship Between Route Points and Default
Handover Settings
The Min Wi-Fi to Cellular Roam RSSI value specifies the minimum Wi-Fi received signal strength
indication (RSSI) threshold below which a call is handed over from Wi-Fi to cellular. This value
represents the minimum threshold for weak coverage areas in the network. It can also be used as a
backup in case a Route Point is missed or for areas that have weak coverage but do not yet have a
Route Point specified.
The Min Cellular to Wi-Fi Roam RSSI value specifies the minimum Wi-Fi RSSI threshold that must be
available for a call to be handed over from cellular to Wi-Fi. This value applies only in cases where the
handover is not triggered by a Route Point. This value should represent an RSSI that is typically only
available within the building so handover to Wi-Fi does not occur outside. This value is also used as a
backup for handing over to Wi-Fi if the user misses connecting with a Route Point when entering the
building.
If a Route Point is present, the handover is triggered based on the Route Point-specific settings, even
if they are different than the values in these fields.
