CPICH power typically takes about 8~10% of the total NodeB power. For a 20W (43dBm) NodeB, CPICH is around 2W (35.1 ~ 33dBm).
In urban areas where in-building coverage is taken care of by in-building installations, the CPICH may sometimes go as low as 5% because:
1) The coverage area is small since users are close to the site, and
Is there any direct connection between the CPICH power and coverage Distance?
ReplyDeleteYes If you reduce CPICH Power by 3dBm than coverage reduce by 1/2.
ReplyDeleteuntrue! this is only valid in free space propagation environment.
DeleteIn dense urban you will expect much more loss of coverage
in case of 20w-43dbm how much coverage distance
