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.
Post subject: Any one who knows lock time of GPRS class12?
Unread postPosted: Tue Dec 14, 2004 10:24 pm
As far as I know between the receive and transmit time slots, one time slot minus the maximum TA is the minimum amount of time left for the RF parameter setting and for the synthesizer lock-up.
The maximum TA value is 63 symbol periods, or 232.615 µs, so this represents 576.923 - 232.615 = 344.308 µs.
But when we talking about lock time of this, it should be locked within 180 µs not 344.308 µs. :?:
Is there anyone who can explain this?
