13.2 Deployment Guidelines

The deployment of CDMA2000 can and does have different faces presented to the designer depending on the situation they are trying to solve. If the design is for a new system, green field the deployment is driven by coverage and then by capacity. On the other hand if the design is for integrating CDMA2000 into an existing system, like IS-95, then the design is more focused on capacity and possible inclusion of packet data services.

Because CDMA2000-1X occupies the same bandwidth as IS-95A/B, this obviously facilitates the introduction of this platform into that type of system. CDMA2000 can be deployed as a distinct carrier or shared carrier with IS-95 systems leading to many possibilities that a design engineer can possibly utilize to achieve the desired design requirement. Some of the design options for integrating CDMA2000-1x into an existing IS-95 system are shown in the Table 13-1.

For cellular, the F1 is the primary channel for the hunt, although for personal communications services (PCS), it is the first channel in the channel selection sequence provided by the operator. The CDMA2000 channel assignment scheme shown earlier is revisited in the Table 13-2 for cellular systems and Table 13-3 for US PCS systems. The asterisk in both Tables 13-2 and 13-3 represents the preferred 3X F1 carrier recommendation at this time of the design cycle. It is important to factor in the possible inclusion or exclusion of 3X in the initial system design and of course the relative location...
