Steps
Install the SIM
POE cable install
Plug the ethernet cable to the gray POE cable where it says Data+ Power
Plug the ethernet cable other end to the MikroTik SXT LTE6 eth1 POE in
Wait till it boots and try to open 192.168.88.1
Set the admin password
Relogin using the new password
Configure the pin for the sim
Enjoy, start using it
Check if the signal graph appears
SINR
SINR, or Signal-to-Interference-plus-Noise Ratio, is a key metric in wireless communication that measures the quality of a wireless signal by comparing its power to the combined power of all other interfering signals and background noise. A higher SINR indicates a stronger, clearer connection with less interference, which leads to better data rates and fewer dropped calls.
What it measures:
Signal (S): The power of the desired signal you are trying to receive.
Interference (I): The power of unwanted signals from other devices, cell towers, or other sources.
Noise (N): The intrinsic background electronic noise present in any communication system.
Why it's important:
Channel Quality: SINR is a fundamental indicator of how good the wireless channel is for communication.
Data Capacity: Higher SINR allows for more complex modulation schemes, which increases data capacity and throughput.
Reliability: A better SINR results in more reliable connections and fewer dropped calls.
Network Performance: It helps in optimizing network performance and maximizing the efficiency of wireless systems like cellular networks.
How it compares to SNR:
Signal-to-Noise Ratio (SNR): is similar to SINR but only considers the signal power versus the background noise.
In wireless environments, interference is a significant factor, making SINR a more comprehensive and practical metric than SNR for evaluating cellular networks.
In simple terms:
Think of SINR as the loudness of your friend's voice in a crowded room compared to all the other chatter and ambient noise. A higher SINR means you can hear your friend much better because their voice is significantly louder than the combined background noise and other conversations.
Reset button
The reset button has three functions:
Hold this button during boot time until the LED light starts flashing, release the button to reset RouterOS configuration (total 5 seconds);
Keep holding for 5 more seconds, LED turns solid, release now to turn on CAP mode. The device will now look for a CAPsMAN server (total of 10 seconds);
Or Keep holding the button for 5 more seconds until LED turns off, then release it to make the RouterBOARD look for Netinstall servers (total of 15 seconds);
Regardless of the above option used, the system will load the backup RouterBOOT loader if the button is pressed before power is applied to the device. Useful for RouterBOOT debugging and recovery.
