= Tutorials =

A number of tutorials are provided enabling users to quickly pick up various aspects of the COSMOS testbed. They are grouped based on functionality and are mostly focused on sandboxes in order to alleviate the pressure on the main testbed.  

== SDR and Wireless ==

COSMOS has multiple SDR devices deployed for experimenter use as listed [wiki:Hardware/sdr here]. Each [wiki:Hardware/Nodes node] consists of a combination of SDRs, sub 6GHz and mmWave RF front ends. This section provides tutorials for SDR usage on COSMOS, illustrating steps to access them, and providing node images, tools required to develop and conduct experiments. The main SDRs device usage is illustrated in the [wiki:./Wireless/BasicUsage basic wireless usage tutorial]. A number of more advanced tutorials include the tutorial on how to [wiki:./Wireless/MeasurementTool instrument your SDR experiment] with the [https://oml-doc.orbit-lab.org OML], while the [wiki:./Wireless/ChannelSoundingKrypton channel sounding tutorial] illustrates the use of custom FPGA code to improve the performance of the SDR platform.
