Packet Data Rates

The next part of the puzzle when performing the design aspect is to review
the relationship between the data rates and the other components that are
affected by the choice of data and its requite speed selected.
The asterisk refers to the fact that there is now a reverse pilot involved
with those configurations of CDMA2000.
Looking at Table 13-21, one is drawn to the conclusion or suspicion that
there must be some other factor involved with system capacity than Walsh
codes as described earlier. As suspected with the differing data rates, there
is a corresponding alteration to the link budget and pole capacity found in
the processing gain aspect. Naturally as data rate increases, the processing
gain is reduced because the overall spreading rate remains constant.
Table 13-22 shows the relationship between the data rates, defined in
Kbps, and the processing gain. It is important to note that the SR and RC
are also involved with the decisions, hence their inclusion in the table.
