“…An understanding of propagation characteristics is TVWS, in scenarios pertinent to secondarysecondary geometries, is an essential factor in better predicting interference in secondary coexistence. Transmitters and receivers of different secondary systems and links might reside indoor in nearby locations [6]. Therefore, it is necessary to apply propagation models for indoor-to-indoor scenarios to assess secondary-secondary coexistence.…”

In this paper, indoor propagation characteristics for TV white space (TVWS) frequency bands are studied. Measurements in the actual indoor environment are performed and described. An indoor propagation model for TVWS is developed, which is useful for evaluating secondary-secondary interference in TVWS scenarios, and its empirical parameters are derived according to measurement results. Our proposed model is based on components of free space path loss, penetration losses of walls and floors, an attenuation coefficient against distance, and an attenuation constant. Frequency dependency of these parameters is derived. Our proposed model is compared with representative indoor models from the literature. Results show that our proposed model, with the obtained empirical parameters, achieves better performance than representative indoor models. The standard deviation of estimation error for our proposed model is only 5.9 dB.

“…The FCC initiative has been followed up by initiation of the development of an IEEE standard "Wireless Regional Area Networks" or IEEE 802.22 WRAN [14], which addresses the unlicensed usage of TV bands. Research studies on the implementation of transceivers for this kind of application exist [18,21] and on the potential adoption of Wi-Fi standards for these bands [17]. European Telecommunications Standards Institute (ETSI) is currently investigating the inclusion of socalled "Reconfigurable Radio Systems" (RRS) in their standards, but no actual standards have been proposed due to the complex nature of CR.…”

The application of wireless personal area network (WPAN) and simple pointto-point wireless communication devices has increased drastically both in private household and in our workspaces in general over the last decade. Combined with the fact that the total number of wireless devices and associated standards present in the wireless environment is experiencing an extreme growth, the frequency spectrum scarcity is exposed as a severe challenge. Setting up efficient and reliable wireless WPAN links can be challenging even today. This is especially true because of the intensive use of the license-free frequency bands, where the level of interference can be extremely high. Combined with the challenges associated with multi-path propagation and attenuation, setting up and maintaining an acceptable level of perceived QoS is a challenging job even for trained professionals. This paper discusses the challenges associated with the implementation of highly reliable low-power WPAN networks for the future and the adaption of Cognitive Radio technology as a potential solution. A brief status on the maturity of CR technology will be presented as an integral part of this discussion.

“…Considering the advantages of using TVWS in terms of capacity expansion and economic viability, a growing interest in establishing new models and approaches for cellular network deployments and mobile broadband service in the TVWS bands has recently emerged [1] [2]. However, most existing and ongoing research work focus on the benefits of using TVWS on the technical design (performance), interference analysis and radio wave propagation models [3] - [7].…”

In this paper we analyze the business feasibility of mobile broadband access services using secondary access of spectrum in the TV bands. We use a capacity-cost analysis considering costs for radio equipment, base station sites and radio spectrum. We compare network deployment by a market entrant and an existing mobile operator using either licensed spectrum or TV white spaces. In addition, we compare the impact of high and low spectrum prices using examples from Sweden and India. The analysis shows that market entrants will be in a more difficult position than the established actors. No matter the cost-capacity performance of cognitive radio equipment, a new operator needs to invest in a new infrastructure with sites and transmission. If the spectrum costs are "high" (like in India) the use of TW white spaces is more cost efficient for both existing operators and new operators.
