IEEE P1900.7

White Space Radio Working Group 

Scope and objectives

The PAR for P1900.7 “Radio Interface for White Space Dynamic Spectrum Access Radio Systems Supporting Fixed and Mobile Operation” was approved by June 16th, 2011.

  • Scope: This standard specifies a radio interface including medium access control (MAC) sublayer(s) and physical (PHY) layer(s) of white space dynamic spectrum access radio systems supporting fixed and mobile operation in white space frequency bands, while avoiding causing harmful interference to incumbent users in these frequency bands. The standard provides means to support P1900.4a for white space management and P1900.6 to obtain and exchange sensing related information (spectrum sensing and geo-location information).
  • Purpose: This standard enables the development of cost-effective, multi-vendor white space dynamic spectrum access radio systems capable of interoperable operation in white space frequency bands on a non-interfering basis to incumbent users in these frequency bands. This standard facilitates a variety of applications, including the ones capable to support high mobility, both low-power and high-power, short-, medium, and long-range, and a variety of network topologies. 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. 

Technical relevance to QoSMOS

Work in P1900.7 is clearly related to WP 4 in QoSMOS. Activities in this working group will be carefully observed and respective contributions were planned.  

Status and outlook for QoSMOS

P1900.7 held its kick-off meeting on 29th and 30th of September 2011. There have been presentations but no significant technical discussions except on an initial work plan and timeline. The plans presented have been considered as rather demanding and there was no clear consensus on the sequence of action items such as decisions on system parameters (grade of mobility, frequency bands to use, regulatory constraints to consider and similar). As a minimum common understanding the TV white space parameters known so far have been adopted as a working assumption (but no decisions have been made).

Two QoSMOS participants were involved in the group so far, one of them was appointed as an independent election processor for the election of the working group’s secretary and vice-chair.

Chairman has been elected now, as of early 2012 vice-chair and secretary positions are still open. First presentations from QoSMOS were submitted, further submissions to 1900.7 are planned.
