LSA system development with sensing for rapidly deployable LTE network

Autor: Lähetkangas, K. (Kalle), Posti, H. (Harri), Saarnisaari, H. (Harri), Hulkkonen, A. (Ari)

Public safety users require radio spectrum for their communication systems. In this study, sensors are proposed as a backup spectrum information source in a rapidly deployed public safety long term evolution (LTE) communication network with licensed
