Hello,

This is regarding the power measurements of GSM based signals.

Suppose I have one GSM carrier with all 8 TS on and each slot has 10W power. Because of the guard period in GSM structure, the actual power read by the power meter will be 0.25 dB low.
So in this case power meter will read 40-0.25=39.75 dBm.
Now consider the case where TS0 has 10 W, TS1->8W, TS3->5W,TS4->3W,Ts5->10WTS6->8W,TS7->9W. In this case what will be the reading of Power meter?

Greetings ljoseph:

I posted a notice about your question on the homepage. You mention specific signal levels in all 8 time slots, but I don't see one listed for TS2.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
