13.10 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.
13.10.1 CDMA2000-1X
The following is a brief design example that is relevant for a new CDMA2000-1X system being deployed as a green field situation. The design example focuses on the issues that are more relevant to the internal network and does not factor into the mix any possible networking and coordination issues with adjacent systems.
Because this is a new CDMA2000 system, the concerns of legacy equipment are not relevant and...
