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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

GSM TS power measurements - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including 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.
