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...

180KHz or 200KHz in GSM? - 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. Note: The RF Cafe Forums were reconstituted in April 2021!

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

Posted: Tue Jul 20, 2004 2:08 am 
when we calculate noise in GSM system, we consider bandwidth as 200KHz
but in some document it is 180KHz as "equivalent noise bandwidth".
so input noise or KTB=120.85dBm or -121.3dBm.
I think when we consider all system include baseband we use 180KHz instead of 200KHz, right?
Any clear answer about this?
