I was reading a fundamental (or beginner) introduction to WCDMA and it said
“Pilot coverage decides the coverage boundary for a particular site. Proper Pilot power planning is very important. Too-weak pilot will lead to coverage holes, whereas too-strong pilots will lead to overshooting and interferance.”
So my question is, What is this Pilot signal? Is it a logical channel like BCCH in GSM? I have seen DT teams use BCCH signal to determine coverage for a particular GSM site. Is Pilot signal like that too? Does it have any other purpose?
Thanks in advance. I would really appreciate your help in grasping the concept.
