Coverage Vs adding 2sd Carrier
Hi friends,
When adding a second carrier, the power per carrier is reduced from 30w to 20w. The CPICH Power is the same in both cases (33dm).
I'm asking if this reduction of the NodeB total power will reduce the coverage?
Regards

Hi,
no change in the coverage areaa s the CPICH power is same, thanks.

Re: Coverage Vs adding 2sd Carrier
of course you get reduction if you measured these values !
how did you get the cpich power value: measured or just read the setting from the OMC nodeb config?
how did you do the config for 2nd carrier: two transmitters combined via hybrids oder a multicarrier TX/PA?

No serving area reduction, for sure!

Different vendor/RF equipment type/ antenna connection will give different results.

Hi
As the CPICH power didn't change so the coverage footprint won't either. But as your power is reduced service Quality, number of users supported, data rates, HSDPA throughput... all will be affected. so the bottom line will be: coverage no change Capacity and quality will both be impacted

Normally, I would anticipate an increase in the reach of the DPDCH as a result of the 2nd carrier addition, due to the reduced loading per carrier. But since, you mention that the power per carrier has been reduced (combiner loss?), and CPICH power is same, then DPDCH coverage should reduce.

Hi firstmaxim, can you explain further? I'm eager to understand.. Thanks..
