A Campus-Wide Testbed Over the TV White Spaces.

by Ranveer Chandra , Thomas Moscibroda , Paramvir Bahl , Rohan Murty , George Nychis , Xiaohui Wang - ACM SIGMOBILE Mobile Computing and Communications Review , 2011
"... We have deployed a wireless network that operates in the white spaces of the TV band spectrum and covers most of Microsoft campus in Redmond, WA. Since the campus is large (approximately 1 mile x 1 mile), there are several shuttles that move employees from one building to another. We have used the ..."

the white spaces network to enable a key productivity scenario on campus -Internet connectivity in campus shuttles. We have modified one such shuttle to operate over the TV band white spaces. A white space radio in this shuttle communicates with two base stations deployed on buildings on campus. Inside

Simplified processing for high spectral efficiency wireless communication employing multi-element arrays

by Gerard J. Foschini, Glen D. Golden, Reinaldo A. Valenzuela, Peter W. Wolniansky - IEEE J. Select. Areas Commun , 1999
"... Abstract — We investigate robust wireless communication in high-scattering propagation environments using multi-element antenna arrays (MEA’s) at both transmit and receive sites. A simplified, but highly spectrally efficient space–time communication processing method is presented. The user’s bit str ..."

Backhauling in TV White Spaces

by Cyrus Gerami, Narayan M, Larry Greenstein
"... Abstract—Since the FCC’s approval of unlicensed use of TV white spaces, the issue of how to use these white spaces has led to innovative technologies such as cognitive radios as well as a variety of spectrum policy proposals. There have been proposals to devise alternate rules for spectrum usage cit ..."

Interference Analysis for Secondary Coexistence in TV White Space

by Angela Sara Cacciapuoti, Marcello Caleffi
"... Abstract—In this letter, the interference among mobile, het-erogeneous and independently-operated secondary networks over shared TV white space is studied. Specifically, a probabilistic model for the secondary coexistence is developed, and, stemming from this, closed-form expressions of the coexiste ..."

KNOWS: Kognitiv Networking Over White Spaces

by Yuan Yuan, Paramvir Bahl, Ranveer Chandra, Philip A. Chou, John Ian Ferrell, Thomas Moscibroda, Srihari Narlanka, Yunnan Wu
"... The Federal Communications Commission (FCC) has announced that it is willing to consider unlicensed operation in the TV broadcast bands. Compared to the ISM bands, this portion of the spectrum has several desirable properties for robust data communications. However, to make efficient use of this sp ..."

of this spectrum in a way that is non-disruptive to incumbents, there are a number of challenges that must be handled. For example, an unused portion of the spectrum must be found, and it is likely that its availability will vary over time. To address such challenges, we present KNOWS, a cognitive wireless

1Interference Analysis for Secondary Coexistence in TV White Space

Wireless Sensor Networking over White Spaces

by Abusayeed Saifullah, Chenyang Lu, Jie Liu, Ranveer Ch, Sriram Sankar
"... White spaces represent unoccupied TV spectrum that could be used for wireless communication by unlicensed devices, just like Wi-Fi and ZigBee devices can use the ISM bands. This low-frequency spectrum enables high bandwidth communication at long transmission ranges. In this paper, we propose a syste ..."

WINET: Indoor White Space Network Design

by unknown authors
"... released the final rule to approve of TV white spaces (TVWS), i.e., locally vacant TV channels, for unlicensed use in 2010. This TV spectrum will mitigate the shortage of wireless spectrum resources and provide opportunities for new applications. TVWS differ from the conventional Wi-Fi spectrum in t ..."

Resource Allocation Techniques for Cellular Networks in TV White Space Spectrum

by unknown authors
"... Abstract—TV white space (TVWS) represents unused TV channels- resulting from the transition to digital over-the-air broadcasting- made available by FCC for unlicensed secondary users. This presents opportunities for new wireless networks and services, for example as a complement to licensed 4G cellu ..."

1Optimal Strategy Design for Enabling the Coexistence of Heterogeneous Networks in TV White

by Angela Sara Cacciapuoti, Marcello Caleffi, Luigi Paura
"... Abstract—Very recently, regulatory bodies worldwide have started to approve the dynamic access of unlicensed networks to the TV White Space spectrum. Hence, in the near future, multiple heterogeneous and independently-operated unlicensed networks will coexist within the same geographical area over s ..."
