Uplink and Performance Tab

Uplink Tab

This dashboard tab facilitates the management of cellular WAN configurations and the monitoring of cellular WAN health over time. Information is organized into categories including Configuration, Status, and Live Data. The Uplink page in the Meraki Dashboard is accessible via Cellular Gateway > Cellular Gateways. 

This section provides information on SIM cards for the device.

The number of SIM card slots displayed on the dashboard depends on the number of SIM slots available on the device. By default, SIM 1 is the primary/active slot.  Primary SIM is the one that will be activated at bootup.  Active SIM, is the sim that is currently being used to establish the cellular WAN connection.  On bootup, the MG will try to activate the SIM card on the primary slot. 

This section displays some of the parameters involved with SIM card configuration on the MG. 


  • ICCID - This is a 18-22 digit number which is derived from the SIM card

  • IMSI - This is a unique 15 digit number which is used by the network to authenticate and identify subscribers.

  • MSISDN - This is the phone number associated with the SIM card or line. 

  • Status - This field displays “Active” if the sim card is actively being used to establish a cellular connection or “Not Inserted” if the sim is not inserted and “Standby” if the sim card is not the active sim.

  • Primary Configuration - This field shows if this particular sim is configured as the primary sim.

  • Access Point Name(APN)- This field displays the APN used for establishing the data session.  

  • IP Type - This field shows the data connection type that would be requested from the cellular network while establishing the data session using APN.   The different options are  IPv4, IPv6 or IPv4v6.  Ipv4 requests for an IPv4 data session only, IPv6 requests for IPv6 data session only and IPv4v6 requests for both IPv4 and IPv6, but the network can provide either or both data sessions. 

  • Authentication - This field shows the authentication method for a device to establish connection to the network. 

If you need to manually enter an APN, then click on the “EDIT” button to open the device configuration editor. This window will allow you to configure the below SIM settings.   


  • Name - This field is to enter the APN provided by the carrier

  • IP type - The user can specify the preferred IP type for the devices connecting through that APN.  The different IP types are IPv4, IPv6 and IPv4v6

Note: MG cannot currently function in a native IPv6-only environment. It is recommended that dual-stack is implemented in order to leverage IPv6 functionality and management.

  • Authentication - This field is used to specify the authentication method for the MG to establish a successful connection.  The different types of authentication are PAP, CHAP and None.

  • Username - This field is used to specify the associated username

  • Password -  This field is used to specify the associated password

Note : If incorrect information is entered for any or all of the parameters mentioned above, it will prevent the establishment of a data session over the cellular network, thereby causing the MG to remain offline.

Click the Update button to save changes made to the configuration.

To modify the default primary SIM slot, utilize the "MAKE PRIMARY" option, which also promptly activates the selected SIM. By default, the device is configured with SIM1 as the primary slot. However, if a SIM card is inserted into SIM slot 2 on a device with no SIM in slot 1, the device will boot up with that particular SIM in SIM slot 2.


In scenarios where two SIMs are inserted:

  • If SIM 1 is primary and active, clicking "Make primary" for SIM 2 will switch SIM 2 to primary and also activate the sim, thus making it Active.

  • If SIM 1 was active and experiences a data connection loss for over 5 minutes, a failover to SIM 2 (the secondary SIM) will occur.

For enhanced redundancy, it is advisable to utilize SIM cards from different carriers in SIM slots 1 and 2.

Uplink Traffic

This graph is used for monitoring the uplink traffic in real time



MG users can now take advantage of this data within the Meraki platform to quickly diagnose what’s affecting cellular connectivity, or what led to performance degradation, through historical stats— signal strength, latency, and loss—that are visual and easy to interpret

Cellular Statistics graph is used for showing signal strength such as the RSRP(Reference signal received power) and RSRQ ( Reference signal Received Quality) .  You can view the data from past 2 hrs to as far as 30 days in the past.  



Similarly you can also monitor the latency and loss over the primary Cellular Uplink.

Signal Strength and Signal Quality

It is recommended to not rely solely on signal bars when troubleshooting. Always check the proper signal values to get more accurate readings. Each of these values can vary for different carriers and technologies.

For transparency, the following values are how the MG cellular gateway calculates signal bars. Signal strength and quality reported will vary per modem.  When deploying the MG cellular gateway, it is important to take into account the values below for a signal type to find optimal signal quality. The RSRP and RSRQ values are relevant when the modem type is in 4G/LTE or 5G.  


Signal Bar


RSRP Range (dBm)

RSRQ Range (dB)


RSRP >= -83

RSRQ >= -7


-83 > RSRP >= -92

-7 > RSRQ >= -10


-92 > RSRP >= -102

-10 > RSRQ >= -13


-102 > RSRP >= -111

-13 > RSRQ >= -16


-111 > RSRP >= -140

-16 > RSRQ >= -20


Interpreting RSRP and RSRQ

RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality) are influenced by various factors in a cellular network.

  1. Distance from the Cell Tower:

As a mobile device moves away from the cell tower, the received signal power (RSRP) tends to decrease. The distance between the device and the cell tower is a crucial factor in signal strength.

  1. Obstructions and Signal Attenuation:

Physical obstructions such as buildings, trees, and terrain can block or attenuate the radio signals, impacting both RSRP and RSRQ.

  1. Antenna Gain and Configuration:

The gain and configuration of antennas at both the cell tower and the mobile device play a role in signal reception. 

  1. Network Load and Congestion:

High network load and congestion can affect the quality of the received signals. RSRQ takes into account interference and congestion levels, providing a more comprehensive quality metric.

  1. Weather Conditions:

Weather conditions such as rain, snow, or atmospheric disturbances can attenuate or scatter radio signals, affecting both RSRP and RSRQ.

  1. Interference:

Interference from other electronic devices, adjacent cells, or co-channel interference can affect the quality of the received signals and, consequently, RSRQ.

  1. Transmission Power of the Cell Tower:

The power at which the cell tower transmits signals can influence RSRP. Higher transmission power generally results in stronger RSRP values.


Keep in mind that these values will vary as conditions change. The above measurements do not give us a definitive answer of what constitutes a successful connection.
