Using cellular modems in a Wireless WAN (WWAN)
The IX10 supports one cellular modem, named Modem, which is included in a preconfigured Wireless
WAN, also named Modem.
The cellular modem can have only one active SIMslot at any one time. For example, Modem can have
either SIM1 or SIM2 up at one time.
Typically, you configure SIM1 of the cellular modem as the primary cellular interface, and SIM2 as the
backup cellular interface. In this way, if the IX10 device cannot connect to the network using SIM1, it
automatically fails over to SIM2. IX10 devices automatically use the correct cellular module firmware
for each carrier when switching SIMs.
Configure cellular modem
Configuring the IX10's cellular modem involves configuring the following items:
Required configuration items
n
Enable the cellular modem.
The cellular modem is enabled by default.
n
Configure the criteria used to determine which modem this modem configuration applies to.
n
Determine the SIMslot that will be used when connecting to the cellular network.
n
Configure the maximum number of interfaces that can use the modem.
n
Enable carrier switching, which allows the modem to automatically match the carrier for the
active SIM.
Carrier switching is enabled by default.
n
Configure the access technology.
n
Determine which cellular antennas to use.
Additional configuration items
n
If Active SIMslot is set to Any, determine the preferred SIMslot.
In the event of a failover to a non-preferred SIM, or if manual SIM switching is used to switch to
a non-preferred SIM, the modem will attempt to reconnect to the SIM in the preferred SIMslot.
To configure the modem:
