FortiGate/FortiWiFi variant LTE feature matrix
The following paragraphs explain what the aforementioned parameters mean.
4G/3G handover
Our LTE modems support both 4G and 3G connectivity. Because LTE connection is always preferred, the modem will
try to switch back to the LTE network whenever the signal is strong enough. Although handover to an LTE network is the
default, this behavior is not very explicit sometimes. To make sure the modem always switch back to the LTE network in
a prompt manner, FortiOS has the “manual-handover” option which, once enabled, will constantly scanning available
LTE signal and send a request to the modem to switch to the LTE network instead of waiting for that modem to act.
Band restriction
You are able to select the allowed radio bands for 3G and LTE services.
LTE modem firmware upgrade
Although the modem is preloaded with firmware for different carriers across the globe, FortiOS supports LTE modem
firmware upgrade to meet our customers' needs. You can upgrade your LTE modem either locally or remotely, with local
method such as usb/tftp transfer or download it from FortiCloud.
LTE modem firmware scheduled upgrade
In addition to letting you manually upgrade your LTE firmware, FortiOS also enables you to set a download schedule to
automatically check for new firmware and to initiate the upgrade process by querying the FortiCloud server routinely.
You can simply set a upgrade schedule to let the FortiOS to check for any update weekly, bi-weekly, or monthly. Refer
to the LTE firmware upgrade section for more detail.
Modem firmware auto switch
In order to accommodate the different requirements of carrier around the globe, the LTE modem is preloaded with
multiple carrier specific firmware. FortiOS will instruct the modem to automatically switch to the corresponding carrier
firmware according to the SIM card inserted.
Carrier modem firmware selection
You are also able to manually select a modem firmware to be used instead of letting FortiOS do it automatically.
