RE: stds-80220-requirements: comments on rev5
I would like to add to Fujio's comments and my earlier contribution.
Multiples of 5 MHz is critical for both a technical performance as well
economic viability (capital efficiency) given other performance
parameters (system throughput, number of users, broadband data models
etc.)
Thanks and look forward to any rationales why less than 5 MHz could be
an option for the MBWA system tied to our current performance
requirements.

I would like to make a comment on John's email of July 23rd on section
4.1.4
as follows.
I don't agree to eliminate this section (John said "stricken") because
the
bandwidth is one of important basic system requirements. A system
cannot be
specified without concrete values of bandwidth.
A broader bandwidth is a current trend of wireless communications, e.g.,
WLAN (e.g., 20MHz), UWB (e.g., >300MHz), possible systems beyond
IMT-2000
(e.g., 100MHz) as well as a general requirement for Mobile "Broadband"
Wireless Access.
I also understand John's rationale to not limit the lower bound of the
bandwidth.
Therefore, how about to have several typical numbers for the bandwidth
as
options in this section?
Best Regards,
Fujio
