 ## Usage 
 
+### UAV command and control
+
 The TFSIK modem is intended to be used at UAV as an "in the air" part of the communication link. For the ground control station, the [TFMODEM](https://github.com/ThunderFly-aerospace/TFMODEM01) is supposed to be used.  
-The reasons for the difference in the air and ground control station units are design tradeoffs.  For the example of tradeoff, the ground control unit needs a very reliable, therefore large interface USB connector, to the ground control station computer. 
-The same connector is impractical to be used in the UAV part. The same applies to the RF filters, antenna connectors, etc. To resolve that, we decided to use different implementations to the ground station, although technically both modems could be used on both sides.

+### ROS2 long-range wireless datalink
+
+SiK firmware is commonly used in radio modems, particularly in the fields of unmanned aerial vehicles (UAVs) and robotics. When integrated into Robot Operating System (ROS) or ROS2 environments, SiK technology offers several advantages. It provides reliable and long-range communication, which is crucial for both indoor and outdoor robotic applications. The low latency of TFSIK01 modems ensures real-time responsiveness, a critical factor in robotics. These modems are highly configurable, offering users the flexibility to tailor the system according to specific needs. Additionally, their compatibility with various communication protocols makes them easy to integrate into existing ROS and ROS2 systems.
