Application

Measuring signal level in NB-IoT, Cat-M, GSM Networks. Performing new installation  on various NB-IoT meters (like; electrical-, water- and gas- meters) and doing service- repair- works on such.

NB-IoT Tester components

The following components are included in the package:

Basics

NOTE: The NB-IoT Tester is a rugged field instrument designed to withstand  fieldenvironment. However, to ensure best performance, it is important to keep maintenance as described later in this manual.

Getting started!

Place SIM-card in the SIM-card reader.
Beneath the unit there is compartment for the internal battery-pack and the SIMcard. Open up the lid and place the SIM-card in the SIM-card reader. Insert the card with connections down and the cut-corner first.

Charging the internal battery-pack
Make sure that that unit is properly charged before using it.
Charge the unit at least 4-6 hours before using it the first time.

Turn On the NB-IoT Tester
Press and hold down the On-button for a couple of seconds then release the button.
The unit will turn On.

• The Tester starts in “ready-mode” after a few seconds and will start to search for available Networks (according to the installed SIM-card).
  Display will show “Connecting” and a timer will tell about the elapsed time.

• Connecting can take up to 3 minutes the first time with a new SIM. Even longer if all bands are searched.

• If a connection is not made in 3 minutes the problem is either that there is no base-station within reach or that the operator needs to be selected manually by entering a MCC/MNC.
  

Measuring mode

• If the Network is found (in connection with the SIM-card) the unit will go into “Measuring-mode” and the display will show signal strength in the form of thermometer scales.
  
  Top row will display operating mode, Operator MCC/MNC code and Band currently used.

The values shown in Measuring mode are:
RSSI          Received Signal Strength Indicator in dBm.
RSRP       Reference signal Receive Power in dBm.
RSRQ      Reference signal Receive quality in dB.
SNR         Signal Noise Ratio in dB.

• The signal levels should be as high as possible and the bars as long as
  possible (with low values in Red/Yellow and top values in Green and as far to the right as possible).

• In this mode the Tester will also tell You the servicing cell ID. This is shown at the bottom of the display.

• If GPS is enabled a green ‘G’ will be shown to the left of the battery when the GPS has locked. When GPS is locked a third screen is available by pushing ‘mode-button’ showing GPS information.

Ping-mode (latency)

Pressing the mode button will take the meter to the Ping-mode where latency is being tested. It is important that a connected device will be able to connect and transmit data as fast as possible. Long delays or even lost packages are a signs of poor signal where another installation site/external antenna can be required.

• Example of good quality, short ping-times:

Pressing the Menu-button will display this:

SOUND
SETUP

Here You can perform a variety of tasks and setup´s.
Use the “UP” / “DOWN” buttons on the meter and verify with the “OK” button to enter the various setup´s.

FINGERPRINT TEST

A very useful and accurate test for checking the signal level at a site. Place the meter where You want to install the new device (like an electrical NB-Iot meter).
Press the “Ok” button and the unit will check the signal level and perform a
“ping-test” It will take about 10 seconds and the result can look like this example:

All the information on the left side is available in the QR-code on the right side.
You can read this QR-code with Your mobile phone making documentation easier. Use a QR code reader app to read this.

FINGERPRINT TEST DELAYED

Sometimes new devices (new NB-IoT meters) will be placed in a closed steelcabinets.. Such cabinets attenuates the signal level quite a bit and in some
cases so much that the device can´t communicate when closing the door to
the cabinet.

In such a case use this method for testing:

Chose the “FINGERPRINT TEST DELAYED”

• Chose a delay time for performing the test (10sec is normally just fine).
• Place the unit inside the cabinet and close the door.
• A FINGERPRINT TEST will be performed when the chosen delay time has run out.
• The meter will “beep” when the test is made (don´t open the door to early – the test takes a little more than 15 seconds under good conditions).

INFO

Information about the instrument, modem and connection.

SOUND

Under some circumstances it can be good to listen to a pitch-tone when doing
installations/searching for the highest signal level.
The higher the tone the better the signal level.
Turn the built in beeper On by selecting one of the three measuring options:

BEEPER OFF
BEEPER ON RSSI
BEEPER ON RSRP
BEEPER ON SNR

The unit will use this function until its turned Off (BEEPER OFF).

SETUP

This is the setup sub-menu.

1. EXIT
   Exit setup menu.

2. AUTO TURN OFF
   Set the preferred time for turning off the unit automatically. Can be setup
   for 5, 10, 20 or 30 minutes “Auto Off”. Or set in the mode “Always On”

3. PING
   This is the ping sub-menu.
   EXIT
   PING SERVER IP

4. EXIT
   Exit setup menu.

5. PING SERVER IP
   Use this to manually set up the server to connect with
   (PING). Use the “Up”/”Down” buttons to change the numbers
   in the IP-address. Enter and save with EXIT.

6. SERVER
   This is the UDP server sub-menu. This server is used to transfer
   measurements to. To use this function a UDP server is needed.
   EXIT
   USE UDP SERVER
   UDP SERVER IP
   UDP SERVER PORT

7. EXIT
   Exit setup menu.

8. USE UDP SERVER
   Select to use the UDP server reporting.

9. UDP SERVER IP
   Use this to manually set up the server to connect with
   (UDP). Use the “Up”/”Down” buttons to change the numbers
   in the IP-address. Enter and save with EXIT.

10. UDP SERVER PORT
    Use this to set up the port.

11. SET APN MANUALLY
    Set APN information.
    EXIT
    SET APN
    SET USER
    SET PASSWORD

12. EXIT
    Exit setup menu.

13. SET APN
    Set APN if the network requires it.

14. SET USER
    Set user name. Normally not used.

15. SET PASSWORD
    Set password. Normally not used.

16. SELECT OPERATOR (MCC/MNC)
    Use this setting for selecting operator. Normally USE SIM is used and
    information on SIM-card is used. But if roaming the operator might need
    to be selected manually. A good web page to find out operators
    MCC/MNC numbers in different countries is: http://www.mcc-mnc.com/

17. COMMUNICATION MODE
    Select mode of operation. NB-IoT, Cat-M or GSM.

18. SELECT BAND
    Set the frequency band to operate on or select ALL to have the band
    automatically searched for. Selecting ALL bands will take the instrument
    much longer time to connect to the network but is good as a starting
    point if the band is unknown. When the band is known it is recommended
    to select the single band. When first connection is made the band used
    will be displayed at the top of screen.
