Radio Elements

Because CDMA2000 is a radio access platform, it leads to reason that the driving
force for dimensioning the network to meet the customer demands is to
ensure that the radio system is dimensioned accordingly. The radio elements that include the base radius, BTS, channel elements, and BSCs, directly
influence the circuit switched and packet data network requirements.
There are a few key elements that are associated with the radio dimensioning
for a CDMA2000 system whether it is any of the 1X variants or
even a 3X system. The key elements for the dimensioning are
■ Spectrum
■ Channel assignment scheme
■ Site configuration (antennas)
■ Channel elements
■ Link budget
The spectrum requirements for a CDMA2000-1X or 3X network are, of
course, directly dependant upon the amount of channels required to be
deployed to meet the current or expected demand. In addition, the channel
assignment scheme that is utilized will have a direct impact on the possible
inclusion of 3X in the future as well as optimal spectrum management
of the existing system when using CDMA2000-1x only.
