Background
IEEE 802 currently does not have a standard method for predicting the impact of mutual
interference between dissimilar wireless networks. As such, there is not standardized method of
assuring coexistence between such wireless networks. In the process of developing new wireless
IEEE 802 standards, it is important to be able to predict when the impact of interference between
dissimilar wireless networks is acceptable and when it is not. The IEEE 802.19 Coexistence
Assurance (CA) Methodology document will describe a method for predicting the impact of this
mutual wireless interference.
Interference Models
In order to predict the impact of mutual interference between wireless networks it is
necessary to build a model of the interference. Interference models can be built at different levels
of granularity and precision. It is the intent of the IEEE 802.19 Wireless Coexistence TAG to
describe in the CA Methodology several modeling techniques, at different levels of precision.
The CA methodology document will explain how to develop three different interference models,
each at a different level of precision. The three modeling techniques are:
Interference Model – Precision Level 1 – Analytic Model
This interference model is based on analytic approximations of the wireless network PHY
and MAC layers. It is understood that since approximations are being uses, the accuracy of the
prediction is less than the other two levels of modeling. However, the benefit of this level of
precision is that the prediction of the impact of interference can be made in less time and with
less effort than the other two levels of precision.
Interference Model – Precision Level 2 – Hybrid Analytic/Simulation Model
This interference model is uses a combination of analytic and simulation techniques.
Portions of the PHY and MAC models are based on analytic approximations and portions of the
models are based on simulation models. This interference model is more accurate than the
analytic model but less accurate as the simulation model. The time effort required to develop
such a model is more than the analytic model and less than the full simulation model.
Insurance Model – Precision Level 3 – Simulation Model
This interference model is bases on simulations of PHY and MAC layers of the wireless
system. This model is the most accurate of the interference models; however, it requires the
most time and effort to develop the model.

Call for Submissions
IEEE 802.19 is interested in receiving submissions for the Coexistence Assurance
Methodology document. Submissions should include a Power Point presentation and (optionally)
a Word document, describing the methodology for building one of the three interference models.
If you are interested in making submission on several modeling techniques, please make separate
submissions for each modeling technique. Submissions should reference interference modeling
techniques known in the literature.
All submissions should use the standard IEEE 802.19 document formats. The document
templates can be found on the IEEE 802.19 web site:
http://grouper.ieee.org/groups/802/19/
All documents should have an IEEE document number and should be placed on the IEEE
802 wireless world web site:
http://www.802wirelessworld.com/index.jsp
The IEEE 802.19 wireless coexistence TAG will hear submission beginning at the March
2004 meeting, in Lake Buena Vista, FL. Anyone interested in presenting at the March meeting,
or a subsequent meeting, please notify Steve Shellhammer (shellhammer@ieee.org) of your
intension to submit, at least two weeks prior to the meeting. The document(s) should be placed
on the IEEE 802 wireless world document server no later than the Friday before the meeting at
which you plan to present.
