How to Verify the Type of Mobile Network Connection

  • The default connection for MOBITEK EC20 router is 4G network. It will try to connect to 3G and 2G if the 4G network is unavailable:-
  • MOBITEK EC20 can be configure to use different type of mobile network:-
  • The preferred network that MOBITEK EC20 will connect to can be configured, here it 4G (LTE) preferred over 3G (UMTS), and preferred over 2G (GSM) :-
  • The “4G signal” below indicates that the MOBITEK EC20 router is connected to 4G network with 5 bars to determine the signal strength.
  • Alternatively, you can check which network MOBITEK EC20 router currently connected to, go to “Administration” -> click on “Console” tab, type “atcmd at+qnwinfo” (all small letters):-

    • first parameter is for “access technology selected”
      • for 4G, it can be:
        • FDD LTE
        • TDD LTE
      • for 3G, it can be:
        • TDSCDMA
        • HSPA+
        • HSUPA
        • HSDPA
        • WCDMA
      • for 2G, it can be:
        • EDGE
        • GPRS
        • GSM
    • the second parameter, “50219”, is the network operator (TELCO) (you can ignore this)
    • the third parameter is, “LTE Band 1”, the type of frequency/band selected (you can ignore this)
    • the forth parameter, 375,  is for “Channel ID” (you can ignore this)

 

How To Solve The Problem With Quectel USB NMEA Port Missing

When connecting MOBITEK Q25 using USB cable, “Quectel USB NMEA Port” is missing and the Device Manager keeps refreshing. When connecting “Quectel USB AT Port” to Hyper Terminal (in below example COM2), the modem is not responding to any AT commands.

MOBITEK Q25 should have 3 ports:

  • Quectel USB AT Port
  • Quectel USB DM Port
  • Quectel USB NMEA Port

Steps to restore “Quectel USB NMEA Port”:

  1. Open Hyper Terminal or QCOM.
  2. Connect using the other “Quectel USB AT Port”. In this example “COM31”.
  3. Use AT+QCFG=”usbnet” to configure the network card type interface.
  4. Type below commands into Hyper Terminal or QCOM.
    • AT
    • AT+QCFG=”usbnet”,0
    • AT+CFUN=1,1
  5. Open Device Manager, “Quectel USB NMEA Port” should appear now.
  6. Connect “Quectel USB AT Port (COM19)” to Hyper Terminal. The port should respond to any AT commands send to it.

How MOBITEK SMS Modem Can Be Used for Transactional SMS?

What is Transactional SMS?

  • used by businesses to relay transactional information.
  • through this type of SMS, businesses can reach subscribed customers directly to share important details that aren’t related to promotional activity.
