  3. Authors / Contributors Stefan Aust (NCOS)

  4. Rationale • The IG-SRU is under way to discuss the creation of a potential Study Group (SG). • IG-SRU should consider the 900MHz ISM radio-band as one of the target bands when creating a potential Study Group. Such 900MHz radio-bands are utilized by PHY/MAC standards, e.g., IEEE 802.15.4g, IEEE 802.11ah. Stefan Aust (NCOS)

  5. Motivation • There are several 900MHz ISM bands globally assigned (USA, Japan, China, South Korea, Australia, Europe, etc.) which are used by standardized PHY/MAC wireless radio systems. • IEEE 802.15.4 and IEEE 802.11 are developing global PHY/MAC standards operating in the so-called “sub-1 GHz” radio-band at 900MHz and will co-exist in the near future. • Improved spectrum usage in sub-1 GHz bands is imminent. Stefan Aust (NCOS)

  6. Directions 1/2 • Identification of spectrum usage challenges in the 900MHz band as part of a potential Study Group creation, such as • Identification of differences between 900MHz and 2.4 GHz radio-bands (more channels, less bandwidth, less tx power, more terminals, etc.) • Classification of co-existence problems • Hidden terminal, packet collisions, inefficient spectrum usage, etc. Stefan Aust (NCOS)

  7. Directions 2/2 • Creation of potential use cases for the 900MHz band which relates to the concurrent use of IEEE 802.15 and IEEE 802.11 systems. • Discussion of potential solutions, measurement reports, efficient use of spectrum, etc. • Results will be used to support the Study Group and may lead to a PAR which then will refer to target bands including the 900MHz ISM radio-band. Stefan Aust (NCOS)

  8. Straw poll • Do you support not to limit the effort of the IG-SRU to 2.4 GHz? • Yes: 8 • No: 0 • Abstain: 0 Stefan Aust (NCOS)
