gsm channel 890

200kHZ/channel,the total is 15MHZ in channel,9 M for china mobile,6M for liantong in china

200Khz is a spacing between channel , My quesion is the bandwidth for a channel , for example , CH62?

The technology is used in ultra-high-frequency (UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands.

The FDMA part involves the division by frequency of the (maximum) 25 MHz bandwidth into 124 carrier frequencies spaced 200 kHz apart.

what do u mean by "spacing between chanel" isn't it the same as a chanel bandwidth?let me know more

i donot know what do y wanted!

From ETSI specification
For example of EGSM uplink

Ch n = 890+0.2n MHz n=0~124
Ch n = 890+0.2(n-1024) MHz n=975~1023

Each channel occupy 0.2M=200kHz bandwidth

I made a mistake , the spacing between channel is just the bandwidth for a channel on GSM. Sorry.
