Reply To: GSM 200 kHZ bandwidth

Hello,

One channel is separated by 200kHz from its adjacent channel. The carrier itself has a very precise frequency. I don’t really like the term “bandwidth” in GSM, when talking about frequency, but that’s just me.

200kHz was chosen in order to provide enough room between channels to avoid interference – without the need of expensive filters in the TRX.
