| Popis: | In this paper, we describe a national level collaborative radio frequency observatory (CRFO) for maintaining a collection of RF measurement data from various Indian states. The online observatory will be primarily used for monitoring and analyzing the national spectrum usage as well as for the development of machine learning based radio signal classification and identification techniques for anti-jamming, interference management, and cognitive radio (CR) systems. Initial results on national spectrum usage analysis observed from different parts of India show that only a small percentage of GSM spectrum is utilized due to service migration of cellular users to 4G networks. It is also seen that the 4G bands are under-utilized during low traffic conditions. The results suggest that depending on the location, the under-utilized spectrum can be used for CR based services. |
