Depending on the required level of protection, the amount of usable TVWS can therefore be drastically reduced compared to the amount of TV channels which are locally not used by the PUs themselves.…”

“…Depending on the required level of protection, the amount of usable TVWS can therefore be drastically reduced compared to the amount of TV channels which are locally not used by the PUs themselves. 2 For the management of TVWS, typically the use of White Space Databases (WSDBs) is proposed [3]- [5]. With this procedure, White Space Devices 3 (WSDs) have to consult a spectrum database in order to identify usable frequency bands at their location.…”

TV White Spaces (TVWS) are a promising frequency resource which will potentially enable various new wireless applications in the field of consumer electronics. Typically, the availability of TVWS is calculated assuming a static frequency allocation of traditional digital terrestrial TV (DTT) networks. In the present paper, additionally, a flexible frequency allocation of a Dynamic Broadcast system is analyzed. A realistic case study is depicted, comparing a traditional DTT network and Dynamic Broadcast with respect to the available amount of TVWS. The outcome indicates that the freed capacity by implementing Dynamic Broadcast can result in a significant increase of available frequency resources for white space devices, as long as an appropriate allocation strategy is chosen. The differences of individual network configurations are studied by means of computer simulations and conclusions are drawn with regard to the network optimization process of Dynamic Broadcast. 1

“…These research works tend to overestimate the capacity, since they do not consider interference from primary users, interference among secondary users, regulations, and cellular traffic offloading. (Dudda, 2012) and (Harrison, 2010) improves above research by considering regulations and interference from other unlicensed devices. (Dudda, 2012) quantifies TV white space in Germany by using the European methodology developed in CEPT ECC SE 43.…”
