4.4.1 Stanford University Interim (SUI) Channels for WiMAX 
A set of 6 typical channels was selected for the three terrain types that are typical at continental 
USA [14].
These models can be used for simulations, design, development and testing of 
technologies suitable for fixed broadband wireless applications as considered in this project.
The typical SUI1-6 channel characteristics are summarized in the following tables. The 
distinctive A, B and C terrain type coefficient values used in path loss calculations are given in 
Appendix B.

As already mentioned six SUI channels are defined to represent closely practical 
implementations with the specifications given below [14]:

Cells are < 10 km in radius, variety of terrain and tree density types

BTS antenna beamwidth: 120


Receive Antenna Beamwidth: omnidirectional (360
o
) and 30
o
. For a 30

antenna 
beamwidth, two times smaller RMS delay spread is used when compared to an 
omnidirectional antenna RMS delay spread. Consequently, the 2
nd 
tap power is 
attenuated by additional 6 dB and the 3
rd 
tap power is attenuated by extra 12 dB (effect 
of antenna pattern and delays remain the same). For the omnidirectional receive antenna 
case, the tap delays and powers are consistent with the COST 207 delay profile models 
[18].
