Sample Basic Designs

Over the new few pages, three basic designs will be covered. The designs
will be rudimentary in nature because the concept of what has to be done
needs to be done is stressed, not a particular design for a particular market
that will not be relevant for any other system.

■ CDMA2000-1X (green field)
■ IS-95 to CDMA2000-1X
■ CDMA2000-1X to 3X
The exact sequence of migration for any system using CDMA2000 1X to
a 3X platform is
■ 1X
■ 1XEV-DO
■ 1xEV-DV
■ 3X
The traffic estimate for all three designs will be the same fundamentally
with a few variants that are relative to the access platform being deployed.
However, a key element to the traffic forecast method is the use of overbooking
data services as well as the issue of the volume of CDMA2000
ready subscriber units. One method of determining the number of available
subscribers that will be CDMA2000-ready is to obtain the estimate of subscriber
handsets that will be procured by the company over the next 6 to 12
months.
