 One method of increasing the resilience and efficiency of a RAN system is to have a single UE device connected to two RAN networks. Using the two networks, the data transmission can be optimized for speed, efficiency, and security. Additionally, if one of the networks were to be compromised, connectivity can be maintained through the other network. All nodes are tagged with attributes including cost and security. A drawing of the system is shown below. Upon updating based on changes in topology, the resilience rApp outputs a different distribution of data among the existing paths to a UE. 
 === Spectrum Management rApp
+The spectrum is a limited resource, thus it is essential to manage the topology across the available frequency channels. 
+Using Spectrum Sensing allows for monitoring the frequency channel occupancy. Multiple methods are available for such action, one of them being energy detection. This method includes measuring the energy of the whole spectrum , and comparing every value of the spectrum with a threshold value. If the value is above threshold, we can estimate the channel as occupied.The algorithm was developed through GNURadio, while the measurements were completed by Universal Software Radio Peripheral ( USRP). 
 
+Through the rApp, the RUs are distributed according to the available channels. This is done by continuously rearranging the .json topology file, and sending the updated version (delta) through a message queueing protocol (AMQP). These data can further be read and utilized for other rApps.
