The Network page contains information related to the device's networking. This chapter is an overview of the Network page in TRB255 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.
|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:
|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:
|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 type. Possible values are:
|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 mobile frequency band.|
|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:
|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|
This tab displays information about the device's local network(s). The figure below is an example of the Network window:
|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|
|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.|
