WAN/Cellular Configuration
Rev 2.3 Feb.12 47
Keepalive
Keepalive is used to test the connection to the cellular network by pinging an IP
address after a specified period of inactivity. Keepalive is only recommended for
users who have a remote terminated device that infrequently communicates to
the network or if you have experienced issues over time where the device can no
longer be reached remotely.
When Keepalive pings the IP address, an acknowledgement indicates there is an
active connection to the network. If the AirLink device does not receive a
response from the IP address, it will make additional attempts according to a
backoff algorithm before determining the Internet connection is not functioning
properly. If it determines the connection is not functioning, the device will then
attempt to reconnect to the carrier to reestablish IP connectivity.
Data Usage Using Keepalive
Keepalive is an optional feature. If you frequently pass data with your device, you
most likely do not need to have Keepalive enabled. When using Keepalive, be
aware that a ping moves approximately 66 bytes of data over the network and is
billable by the carrier. The following *IPPING settings will incur approximate
monthly data usage in addition to any other data usage:
*IPPING Estimated Usage
15 minutes 400k/month
30 minutes 200k/month
60 minutes 100k/month
120 minutes 50k/month
