Classes of Coexistence Abstract A device or
system may be characterized by different
coexistence classes in different
bands Purpose To explore the concept of
creating various classes of coexistence Notice T

Varying facets of Coexistence

• Ability of a system to
• Perform its own tasks, possibly in hostile
  environment
• Detect other systems
• Adapt to presence of other systems
• Reduce impact of its operation on other systems
• Negotiate with other systems
• Are to be evaluated both in-band and out-of-band
• Depend strongly on separation distance
• Are defined and conceived of differently in each
  organization

Proposed Coexistence Classes

• 0 Ignorant of possibility that other systems or
  protocols may exist
• Aware that others may exist, expects them to make
  any adaptations
• Aware that others may exist, unilaterally acts to
  reduce impact
• Actively detects others, unilaterally acts to
  reduce impact on them
• Actively detects others, negotiates with them to
  optimize mutual performance
• A device or system may be characterized by
  different coexistence classes in different bands.
  e.g. An AFH Bluetooth WPAN is class-3 wrt
  802.11b, but may be class-0 for some proprietary
  ISM systems
