Scott Agreed these are good changes. Also, last paragraph of the conclusion, "... and also shows an examples of a services provided ....", delete both "an" and "a". In the references, there is a shorter link to [Ofcom Implementing] : http://stakeholders.ofcom.org.uk/consultations/geolocation/statement/

In the ITU-R Table of frequency allotment, there are bands where primary and secondary services already exist. White Space opportunistic use would then become some sort of tertiary service usage. - Penultimate sentence of section 9: add a coma as follows: "From these use cases, requirements are determined." - Section 11, first reference: (802.11p) ... - Section 11, add a new second reference: (802.22) IEEE, "IEEE Standard for Information technology - Telecommunications and information exchange between systems - Wireless Regional Area Networks (WRAN) - Specific requirements; Part 22: Cognitive Wireless RAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications: Policies and Procedures for Operation in the TV bands; http:// standards.ieee.org/getieee802/download/802.22-2011.pdf", July 2011.
