Hi friends…
in this topic I want to gather CDMA2000 1x and EVDO RF engineers to dicuss about our networks, argue about the frequent problems, share knowledge and solve each others problems…
This will be a great thing to know what are the common problems of CDMA networks and how to solve them…
I will start firstly,
what do you think about enabling the HHO in the network in case of having more than a carrier in the network? did anyone faced problems from that?
No one interested??
Hi,
I think not only CDMA2000 but also for 3G WCDMA/UMTS RF optimization
I agree with this discussion
I agree with you Gpra, what do you think Hassen?
me too gprastomo and taki
the first generation was NMT analog system after GSM comes GPRS & EDGE .Now it is time to master UMTS
Excellent ideas.
THINK IS GOOD,I`LL LIKE IT
agree
so i wanna start 1 topix, how to optimize paging performance in cdma network? since paging problem not only rf part but bsc, msc part as well
for all of you, have you ever done some paging performance optimization? can you start to explain one by one?
thx

Dear friends, a newbee has a question .
Does, anybody know, “why the Download throughput can’t reach 3,1 Mbps, although i had drive test it with single user, single PN, C/I is above 13 and DRC around 3072?” 
How much the highest throughput (in theoretical and implementation)?
Perfect I agree with Armagedon. And lets dedicate this section only to CDMA.
I come with the following question.
what’s the reason for this? if the EC/Io it’s under -16-17 you can’t demodulate anything
it’s necessary to enable HHO .but you should decrease the power on the second carrier .usual you will put the second carrier just on few BTSs with big traffic.The Ec/io on the second carrier will be much better than on 1st one(no noise from neighbor MSs)…usual you can start with 3 db less than 1st carrier.
