In this demonstration paper we describe a prototype of an LTE system deployment that opportunistically exploits the spectral white spaces in the upper UHF TV bands, intelligently guided in its spectum access by a radio environment map (REM). The architecture is modular in the sense that interfaces are generic and minimal. In the proposed demo we will illustrate how information of primary transmitters...
This paper analyzes the possibility to introduce a WiFi type of secondary network containing multiple secondary access points (SAPs) in TV bands. In particular, the analysis investigates the limitations of TV whitespace (TVWS) usage imposed by the aggregate interference of the secondary users towards the primary and secondary system, assuming different levels of penetration of the TVWS-operating technology...
The secondary usage of TV white spaces (TVWS) is one of the most promising implementations of the cognitive radio concept. At the same time, the TV broadcasting services should not be affected by harmful interference from secondary users. This paper investigates the FCC (Federal Communications Commission) and ECC (Electronic Communications Committee) proposed rules for enabling secondary spectrum...
