6. Scope of Proposed Project

{what is being done, including technical boundaries on the work}

{This should be brief (less than 5 lines recommended)}

[The scope of the proposed project will be to develop a Recommended Practice for BWA systems to minimize interference so as to maximize system performance and/or service quality. This practice will quantify acceptable limits for undesirable emissions from BWA systems. It will also recommend tolerance levels for interference or other undesired emissions from other terrestrial and satellite systems. Interference parameters will include co-channel interference, adjacent channel interference, and out-of-band emissions.]

  1. What does it mean?:
  2. A. Separation distance, antenna techniques, power levels, unwanted (OOB and spurious) emissions, susceptibility levels, RX selectivity, etc. This practice addresses interference issues such as like and un-like systems, operating in the same or other frequency blocks, in same or other geographic areas.


B. This practice does not address interoperability issues or self-interference caused by frequency re-use approaches.



7. Purpose of Proposed Project:

{why it is being done, including intended users, and benefits to users}

{This should be brief (less than 5 lines recommended)}

[The purpose of this practice is to provide guidelines for minimizing interference between BWA users as well as minimizing interference between BWA users and other wireless services. This practice will benefit license holders, service providers, equipment suppliers, deployment groups, system integrators, industry associations, component suppliers and network planners by providing a consistent co-existence plan.

A Co-existence Practice definition will facilitate quick deployment of robust BWA systems and will provide a safe harbor for license holders against interference claims.

The intended users include license holders, service providers, equipment suppliers, deployment groups, system integrators, industry associations, component suppliers and network planners.

Benefits to User:

  1. Facilitates co-existence for different systems from different manufactures with higher assurance that system performance objectives are met.
  2. It will minimizes the need for case-by-case interference studies.
  3. Creates favorable conditions for deployment and operation of BWA systems.
  4. Facilitate minimum separation distances (space, frequency, time, etc) by maximizing efficient utilization of spectrum.
  5. Provides for minimal cost systems.

9. Are you aware of other standards or projects with a similar scope? [Yes] {Yes, with explanation below/ No}

[The Broadband Radio Access Networks (BRAN) Committee of the European Telecommunications Standards Institute (ETSI) has a project known as HIPERACCESS which is in the early stages of an attempt to standardize broadband wireless access in Europe. This is a regional standards effort with limited participation by the rest of the world. Furthermore, the project addresses regional markets with specific regulatory conditions distinct from those of other areas. We have held a joint meeting with this group and appointed a liaison. We plan to coordinate with them and will seek harmony where possible.]
