GSM TS power measurements - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.
