STANDARDIZATION OF TV WHITE SPACES SYSTEMS

Active Working Groups

ETSI Reconfigurable Radio systems (RRS) WG1 – System Aspects (link)

TS 103 145 “System Architecture and High Level Procedures for Coordinated and Uncoordinated Use of White Spaces”

Scope of work to be undertaken: This technical specification defines the system architecture for the use of spectrum by White Space Devices (WSDs), specifically in the UHF TV Bands. The scope of the work will be to define the architecture of a system which can allow operation of WSDs based on information obtained from Geo-location databases. The architecture will consider both uncoordinated use of White Space (where there is no attempt to manage the usage of channels by different WSDs) as well as coordinated use of White Space (where some form of channel management and/or coexistence techniques are employed to efficiently use the White Space). This architecture, will serve as an input for defining the Harmonized Standards and European Standards that are part of the EC mandate for Reconfigurable Radio Systems (M/512).

TS 103 143 “System Architecture for Information Exchange between different Geo-Location Databases (GLDBs) enabling the operation of White Space Devices (WSDs)"

Scope of work to be undertaken: To develop a European standard for the architecture and procedures for information exchange between different GLDBs enabling the operation of Cognitive Radio System (CRS). The parameters and procedures for such information exchange, including security and reliability aspects.

EN 303 144 "Parameters and procedures for information exchange between different GLDBs"

Scope of work to be undertaken: To develop a European standard for the architecture and procedures for information exchange between different GLDBs enabling the operation of Cognitive Radio System (CRS). This standard will cover the parameters and procedures for such information exchange, including security and reliability aspects. Inputs from relevant groups such as CEPT will be considered. 

EN 303 387-1 "Signaling Protocols and information exchange for coordinated use of TV White Spaces; Part 1: Interface between Cognitive Radio System (CRS) and Spectrum Coordinator (SC)"

Scope of work to be undertaken: This European Norm defines the interface between Cognitive Radio System (CRS) and Spectrum Coordinator (SC) in Coordinated use of TV White Spaces. This interface has been identified as a standardisation candidate in ETSI TS 103 145 following the TC RRS work flow recommendation (Protocol and Interfaces Specification). This activity falls under EC Mandate M/512.

IEEE DYSPAN-SC (P1900 family) (link)

IEEE 1900.1 Working Group on "Definitions and Concepts for Dynamic Spectrum Access: Terminology Relating to Emerging Wireless Networks, System Functionality, and Spectrum Management"

Scope of work to be undertaken: Since January 2013 the IEEE 1900.1 Working Group has been concentrating on preparing a root-and-branch revision of the original baseline standard that was published in 2008. It is intended that this revision will provide an up-to-date viewpoint on the associated fast-moving technology areas. It is also intended that this revision will enhance the informative content detailing the relationship between the various concepts covered by the standard.

IEEE 1900.7 White Space Radio Working Group

Scope of work to be undertaken: This standard specifies a radio interface including medium access control (MAC) sublayer(s) and physical (PHY) layer(s) of whitespace dynamic spectrum access radio systems supporting fixed and mobile operation in whitespace frequency bands, while avoiding causing harmful interference to incumbent users in these frequency bands. The standard provides means to support P1900.4a for whitespace management and P1900.6 to obtain and exchange sensing related information (spectrum sensing and geo-location information). This standard is a baseline standard for a family of other standards that are expected to be developed focusing on particular applications, regulatory domains, etc.

IETF PAWS Protocol to Access White Spaces Database (link)

The overall goals of this IETF working group are to: standardize a mechanism for discovering a white space database; standardize a method for communicating with a white space database; standardize the data formats to be carried over the defined database communication method; ensure that the discovery mechanism, database access method, and query/response formats have appropriate security levels in place.
