May11-cesg-1 status:OKCAUTIONPROBLEM comment: Very Good SOIS Area Report Wireless WG Goals for the spring meeting Complete the discussions and agree on the second recommended practice of the low data-rate wireless communications Magenta book Further define the technical architecture and the cooperation and administrative framework of the shared test bench for smart sensors Working Group Status RFID-Based Inventory Management Systems Magenta Book submitted to editing review, to be followed by first Agency review. The WG to evaluate the need to define the RFID encoding (tag content), which requires additional expertise (currently under investigation). Low data-rate wireless communications for spacecraft monitoring and control Magenta book to be completed (two use-cases) during the summer and submitted to CCSDS before the Fall meeting Discussions took place about organizing a workshop on wireless technologies to be held in the North America in 2012 The WWG agreed in nominating Jean-François Dufour (ESA/ESTEC) as group chairman in replacement of Patrick Plancke (ESA/ESTEC) now retired. Working Group Summary Situation

May11-cesg-2 SOIS Area Report WG status Consensus achieved on all open issues Contention-based access when the spectrum environment is controlled, low overhead needed and l - IEEE Scheduled-access for use when deterministic behaviours and higher interference tolerance is needed - ISA100.11a (International Society of Automation) -- (potential patent issue under investigation) Remaining tasks Identified and assignments made to team members Book is to be completed and reviewed at SOIS-level before the end of the summer prior to submission for CESG review Wireless WG “Low data-rate wireless communications for spacecraft monitoring and control” (This magenta books identifies a number of use cases for the application of wireless technology, ranging from AIT to onboard sensor networks and recommends commercial wireless standards)

May11-cesg-3 Wireless WG Low data-rate wireless communications for spacecraft monitoring and control (cont) To assist in the joint evaluation of potential technology and commercial devices, the group continued the work on the definition/exploration of a “Smart Sensor Inter-Agency Reference Testbench (SSIART)” This is an effort to coordinate the work in wireless networking projects of each agency and to leverage on that work to simplify the overall testing efforts and technically prepare future updates (e.g. new use-cases) of the MB Intended as a controlled test environment with associated test procedures for assessment of wireless technologies and engineering metrics for wireless spacecraft communications, including common hardware and software Need to investigate proper channels and procedures for interagency (ESA/NASA/CSSAR/CSA) collaboration (e.g. potentially ITAR issues)

May11-cesg-4 1.ASWG –architecture updated and consolidated to cover NASA, AFRL and ESA avionics, three books under final publication process 2.Wireless WG – Low data-rate wireless communications for spacecraft monitoring and control Magenta book under final update, major step forward on defining the inter-agency test bench 3.SDR SIG – completed initial discussion, agreed to continue interaction with Agency experts to arrive at final conclusion E.
