Change "the baud rates and RF channel bandwidths have been left somewhat
flexible in order to allow service providers..." to "several baud rate
options and RF channel bandwidth options are required in order to allow
service providers..."

[Reason for Edit]
This is more accurate than "somewhat flexible"

[Detailed Description of Proposed Insertion, Deletion, Change]
Replace the section starting with "The following tables..." and ending with
"...0.25, and 0.35." with the following:
"It is recommended that the system will generally support baud rates in the
range of 10 to 32 MBaud. Nyquist Root-Raised Cosine pulse shaping with a
roll-off factor of 0.15, 0.25 and 0.35 will be used. 

The system shall operate on one or more of the recommended channel
arrangements presented in the following tables. Although other vendor
specific channel sizes and baud rates may also be implemented it is expected
that the listed channel arrangements will address the majority of deployment
scenarios worldwide.

Note that baud rates are chosen to provide an integer number of PSs per
frame. The frame size choice compromises between transport efficiency (i.e.,
frame overhead) and latency."

[Reason for Edit]
Provides a better and clearer guidelines and explanations of choosing
channel arrangements
