Provides the ability for a Cisco ISR, IR or CGR router to automatically return its cellular service to LTE if it has fallen to 3G or 2G (if LTE service is available). Without the applet, the router may remain on 3G even if LTE service is available. This is due to current LTE standards as implemented in LTE modems and networks.
•Automatically restores ISR Radio Access Technology (RAT) to 4G LTE if it has fallen to 3G or 2G
•This can temporarily occur due to weather conditions, interference, cellular network congestion
•Although LTE reselection is automatic, standards dictate that a device’s LTE modem be in idle mode to reselect (up to 15 seconds w/no traffic up or down). Easy for phones, not for routers
•This app can be set to run at any desired frequency and/or time-of-hour/day/week.
This version supports a single ISR cellular interface. Note that there is a cellular service disruption of ~15 seconds if in 2G/3G mode and the app attempts to restore 4G operation.
Requires one environment variable called timer and the value must be in form of crontab. Example to run the script everyday at midnight local time.
