The information in this page is updated in accordance with firmware version TRB14X_R_00.02.03.1

Summary[edit | edit source]

The Network page contains information related to the device's networking. This chapter is an overview of the Network page in TRB142 devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode", which is located at the top-right corner of the WebUI.

LAN[edit | edit source]

This tab displays information about the device's local network(s). The figure below is an example of the Network window: Networking rutx manual network lan v1.png

lan information
Name LAN interface name
IP address IP address of the LAN interface
Netmask Netmask of the LAN interface. In a sense, a netmask specifies the size of a network. In other words, it indicates which part of the IP address denotes the network, and which denotes the device
dhcp leases
Hostname Hostname of a LAN client
IP address IP address of a LAN client
MAC address MAC address of a LAN client
Leasetime remaining Remaining lease time for a DHCP client. Active DHCP lease holders will try to renew their DHCP leases after a half of the lease time passes.


Mobile

The Mobile tab displays information about the mobile connection. The figure below is an example of the Mobile tab: Networking trb14x manual network v2.png


field name description
IMEI The IMEI (International Mobile Equipment Identity) is a unique 15 decimal digit number used to identify mobile modules. GSM network operators use the IMEI to identify devices in their networks
SIM card state The current SIM card state. Possible values are:
  • Inserted - SIM card is inserted and ready to be used
  • Not inserted - SIM card is not inserted
  • Unknown - unable to obtain SIM card state value. Possible communication issue between the the device and the modem
IMSI The IMSI (international mobile subscriber identity) is a unique 15 decimal digit (or less) number used to identify the user of a cellular network
ICCID SIM card's ICCID - a unique serial number used to identify the SIM chip
Operator Network operator's name
Operator state Shows whether the network has currently indicated the registration of the mobile device. Possible values are:
  • Unregistered - not registered to a network and the device is not currently searching for a new operator to register to
  • Registered (home) - registered, home network
  • Searching - not registered to a network, but the device is currently searching for a new operator to register to
  • Network denied - registration to network denied by operator
  • Unknown - operator state is currently unknown
  • Registered (roaming) - registered to network, roaming conditions
Cell ID The ID of the cell that the modem is currently connected to
Data connection state Indicates whether the device has a mobile data connection or not
Connection type Mobile connection connection type. Possible values are:
  • 4G: 4G (LTE)
  • 3G: 3G (WCDMA), 3G (HSDPA), 3G (HSUPA), 3G (HSPA), 3G (HSPA+), 3G (DC-HSPA+), 3G (HSDPA+HSUPA), UMTS
  • 2G: 2G (GSM), 2G (GPRS), 2G (EDGE)
  • N/A - not possible to determine at the moment
Signal strength Received signal strength indicator (RSSI) measured in dBm. Values closer to 0 indicate a better signal strength
Carrier Aggregation LTE Advanced Carrier Aggregation, CA, is one of the key techniques used to enable the very high data rates of 4G to be achieved.

By combining more than one carrier together, either in the same or different bands it is possible to increase the bandwidth available and in this way increase the capacity of the link.

Connected band Currently used frequency band. For more information on supported frequency bands
Other signal level measurements Overall signal quality for different connection types is defined by different measurements. Short explanations and recommendations are provided below. Click here for more in-depth information or click on one of the links below:
  • 4G
    • RSRP - reference signal received power, measured in dBm. Values closer to 0 indicate better signal strength
    • RSRQ - reference signal received quality, measured in dB. Values closer to 0 indicate a better rate of information transfer
    • SINR - signal-to-interference-plus-noise ratio, measured in dB. Higher values indicate a better rate of information transfer
  • 3G
    • EC/IO - downlink carrier-to-interference ratio. Values range from -20 to 0 (closer to 0 indicates better signal quality/cleanliness)
    • RSCP - received signal code power. Values range from -124 to 0 (closer to 0 indicates better signal stength)
  • 2G
    • RSSI - received signal strength indicator, measured in dBm. Values closer to 0 indicate better signal strength
Bytes received Amount of data received through the mobile interface
Bytes sent Amount of data sent through the mobile interface
Restart Modem Restarts the devices module
