RE: stds-80220-requirements: Max Tolerable Delay Spread, 4.2.3
Joanne,
Several contributions from participants in the channel modeling group have
included proposed channel models for different environments including rural,
suburban, and urban/dense-urban. Urban/dense-urban channel models reflect
the highest delay spread, and 5 micro-seconds is typically accepted as a
suitable value for this type of environment. If the system is going to work
under these conditions, then it must be able to tolerate a delay spread of
atleast 5 micro-seconds.

Neka,
You have provided a rationale for your proposal,
"The maximum tolerable delay spread should be specified so that it
can be
determined whether various vendor proposals can meet this
criteria."
which I don't believe to be a valid reason for establishing such a
requirement.
Can you provide any other reasoning for this proposal? I would expect the
rationale to explain why such a requirement would be essential for the
802.20 MBWA
to achieve it performance objectives.
