  4. COEXISTENCE • Multiple wireless devices are said to “coexist” if they can be collocated without significantly impacting the performance of any of these devices [IEEE 802.15-99/088r2]. • The ability of one system to perform a task in a given (shared) environment where other systems may or may not be using the same set of rules. Richard Kennedy, Compaq Computer Corporation

  5. INTEROPERABILITY • The ability of two systems to perform a given task using a single set of rules Richard Kennedy, Compaq Computer Corporation

  6. Range of CONVERGENCE Objectives • One Global Standard (1) • Based on a combined standard • Based on selecting one of the existing standards • Bringing the three standards closer together; having a degree of interoperability (3) • Being able to coexist (5) • Status quo (99) Richard Kennedy, Compaq Computer Corporation

  7. Degrees of CONVERGENCE Definition • There are a range of convergence options listed below in decreasing desirability. • One Global Standard with complete interoperability(1) • Systems having a degree of interoperability (3) • Systems having a degree of interworking typically involving the use of a translator. • There are two other situations that represent no convergence. • Being able to coexist (5) • Being unable to coexist Richard Kennedy, Compaq Computer Corporation

  8. Examples of CONVERGENCE • Systems adhering to One Global Standard with complete interoperability that can be used anywhere in the world. • Systems that interoperate but were designed to different standards. The user of each equipment type can communicate transparently with the other. • Common: Two standards have common architecture, design, defn • Interoperable: Two+ standards have a way of directly communicating together to perform a task Richard Kennedy, Compaq Computer Corporation

  9. Examples of Standards CONVERGENCE • Common: Two systems have common architecture, design, definition. • Interoperable: Two+ systems have a way of directly communicating together to perform a task. • Interworking: Two+ systems can exchange information thru a translating function and work together to perform a task. • Data transfer: Two+ systems can exchange information thru a translating system to perform their respective tasks. For example HL2 and 11a can communicate via an ethernet backbone. This not considered to be convergence. Richard Kennedy, Compaq Computer Corporation

  10. INTERWORKING • The ability of two systems to perform a task given that each system implements a different set of rules. • The means whereby terminals connected to a telecommunication network may communicate with terminals of another network. [IEC 1992] • To express interactions between networks, between end systems, or between parts thereof, with the aim of providing a functional entity capable of supporting an end-to-end communication. The interactions required to provide a functional entity rely on functions and on the means to select these functions. [ITU-T I.510] Richard Kennedy, Compaq Computer Corporation

  11. COMPATIBILITY and BACKWARD COMPATIBILITY Richard Kennedy, Compaq Computer Corporation

  12. COMPLIANCE Richard Kennedy, Compaq Computer Corporation

  13. COOPERATION and HARMONY Richard Kennedy, Compaq Computer Corporation

  14. SEAMLESS ROAMING and HANDOFF Richard Kennedy, Compaq Computer Corporation

  15. QUALITY of SERVICE Richard Kennedy, Compaq Computer Corporation
