Hello
for CDMA (800 or 850 whatever you call), the total frequency range is:
824–849 MHz/869–894 MHz (uplink/downlink)
Consider either up-link or down-link, the total band is 25 MHz. We know CDMA use 1.25 MHz band, hence the number of total channel/band for either link should be (25/1.25) MHz= 20; This is logical, just like GSM 25 MHz band has 124 channel, each with 200 KHz width + guard bands.
However I hardly could find any information in the Internet regarding the total number of channel in CDMA. Thus, I understand that there might be some other facts that need to be considered in such a band.
SO, please clarify me if the channel number 20 is right?. Please be precise while answering and do answer only if you are well aware of this matter.
Thanks in advance.
