Does AMPS co-exist with WCDMA? - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

Per my understanding, due to AMPS signal co-existing
with CDMA signal, there is Single Tone Desense (STD)
spec for CDMA. I know that in WCDMA there are blockers
spec for GSM signal. How about AMPS for WCDMA? I
think that they could be operating in the same frequency.
For example, CDMA cell band center frequency is
836.5MHz, and WCDMA band 5 center freqeuncy is 836.5MHz.
Why AMPS signal will not bother WCMDA like CDMA?
My only guess is that operators could make sure
not to let AMPS co-exist with WCMDA.
I would like to know if any carrier uses AMPS as
I doubt about it.
