This chapter describes TV White Space (TVWS) network measurements and
trials conducted in Finnish WISE projects from 2011 to 2015. A TV white
space test network environment was developed and built in Turku,
Finland, to aid standardisation and to demonstrate the technical
capabilities of TV white space networks. The test network environment
was the first in Europe to have a geolocation database control the
frequency use. This chapter introduces interference measurements
conducted to aid the standardisation work in the CEPT/ECC SE43 group.
These measurements and the work in the SE43 group served as base
information in the creation of an ETSI harmonised standard for TV white
space devices, ETSI EN 301 598. The chapter also presents application
pilot trials conducted to demonstrate the technical feasibility of TV
white space networks: a long-term video surveillance trial in Turku, and
two additional trials for public transport in the Helsinki area, one
for ticket sales and the other for the transit information screens.
