Cell Modem

About

The cellmodem plugin is a monitoring plugin for cellular modems. It reports provider and signal quality for GPRS/UMTS(3G)/HSDPA(3.5G) modem cards. It works with (mostly) all cards which support an out-of-band channel for monitoring purposes.

The current features include:

  • Display the current network type (GPRS/UMTS)
  • Display the current signal level
  • Configure the maximum signal level
  • Configure the low and critical signal level
  • Asking for PIN if modem needs it
  • Quick visual feedback on modem and registration status via LEDs

To-do and Wish List

  • [Wish] Support to start and stop pppd.
  • [ToDo] Add keyboard shortcut to enter PIN
  • [ToDo] Feedback if PIN worked, and if not how many attempts left.
  • [ToDo] Entering PUK to unlock after invalid PIN entries

Known problems

  • Some cards/drivers sometimes stop to respond on the control channel. This is a driver issue and not a plugin issue. If you come across this problem please e-mail me so we can find a workaround for it.
  • Some cards/drivers (happened with me with nozomi driver, Globethrotter 3G/EDGE card) sometimes reply no registration when it is registered. This seems to be related to the card firmware. I will try to find a workaround when it happens again.
