[Invited Talk] Public-Private Cooperative Cognitive Radio Access Networks: System Components, Technical Target and Issues, Key Functions and System Integration

摘要

Cognitive radio is a dynamic air interface technology which utilizes the limited amount of radio spectrum resource and accommodates more various types of traffic without increasing the required system bandwidth. In this paper, in the context of the heterogeneous cognitive radio access networks which adequately find the underutilized radio resource among multiple radio interfaces, we propose public-private cooperative cognitive radio access networks. Our public-private cooperative cognitive radio access networks consist of "public cellular and/or hot spot networks", and "private WiFi community networks, like FON[1]", and realize reliable Internet access services with less time and cost of service area expansion. This paper highlights, system components, technical target and issues, key functions and system integration.
