Document Type	Green
Description of Document	The mission of the Wireless Working Group (WWG) is to serve as a general CCSDS focus group for wireless technologies. The WWG investigates and makes recommendations pursuant to standardization of applicable wireless network protocols, ensuring the interoperability of independently developed wireless communication assets. This document presents technical background information concerning uses and applicability of wireless networking technologies for space missions. Agency-relevant driving scenarios, for which wireless network communications will provide a significant return-on-investment benefiting the participating international agencies, are used to focus the scope of the enclosed technical information. It is the goal of the WWG that this Green Book shall serve as a single point of reference for wireless network technologies, technical information, and a compendium of agency-applicable use case scenarios. The Spacecraft Onboard Interface Services (SOIS) WWG is focused on wireless, either RF or optical, networks, (i.e., WLAN, WPAN, WMAN, and sensor networks) and does not consider point-to-point wireless standards that are addressed by other CCSDS technical areas including Space Link Services (SLS) and Space Internetworking Services (SIS). The goal of the Wireless Working Group is to provide the CCSDS development community and participating members, with standards-based resources to achieve interoperable wireless network communications, including specific protocol recommendations for anticipated communication scenarios associated with, but not limited to, Lunar and Martian exploration activities. The CCSDS has subcategorized wireless short-range and surface proximity networks as: 1) Intra-vehicle: Internal vehicle (or habitat) extremely short- range wireless links and networking (up to 10 m range). 2) Inter-vehicle: Vehicle-to-vehicle short-range and medium range (up to 20 km). 3) Planetary surface-to-surface wireless links and networking (up to several kilometers). a. EVA (Extra-Vehicular Activity) local links with planetary rover vehicles (RV) and/or habitats; b. RV-habitat links when RV is close to habitat; c. Links between independent local systems (e.g., habitats, robots, external assets). 4) Orbiter relay-to-planetary surface links and networking. This Green Book focuses on intra-vehicle wireless networking technologies and scenarios. Special emphasis is given to inventory management and asset tracking application scenarios. The WWG Green Book will be evolved in future releases to include planetary surface-to-surface wireless links and networking.
