GSM TS power measurements - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

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.
