Anil_S 6 Report post Posted February 5, 2007 I use skype regularly. But when I use skype through R Connect, the voice normally cracks, some times some portion of the voice gets lost. But at some locations there is no problem, it works fine. What can be the reason. I have been checking speed , normally it is around 100 kps ( checked through mtnl broad band site) I have also used "at+crm=1; +cso=33" but no improvement. I have Nokia 2112 & DKU 50 cable & it is installed as Nokia "CDMA 1xRTT 3G Packet Data Modem". I have no issues with the speed, as it is always good & normally at 100 kbs. At my house i get around 180 kbps. Please help Share this post Link to post Share on other sites
Honest 836 Report post Posted February 5, 2007 ^^^ My dear friend, it seems to be the problem from the server. As sometimes the same problem exists in Yahoo Messenger also. Regards. Share this post Link to post Share on other sites
anujit 0 Report post Posted February 5, 2007 Yeah RConnect isnt the best tool for voice calls because you don't always get a consistent connection/throughput. You should only try voice calls with a broadband connection that has a stable throughput. Share this post Link to post Share on other sites
Anil_S 6 Report post Posted February 6, 2007 I know that there are some inherent latencies issues while using internet through CDMA networks. These inherent latencies issues during data transmission make the voice cracking. The reason for putting the problem on forums was to discuss the same & if there is any way to reduce the same. I already have MTNL broad band at home & office & Skype works fine there. I use netconnect only when I am outstation & normal broadband is not available. At some locations I found the the voice doesn't crack at all ( Jaipur near airport & some remote places in Rajasthan) but at some locations the voice quality is so bad that you can hear nothing. There appears to be some thing called "EV-DO" with CDMA networks which can reduce these latencies. Are there any strings like "at+crm=1; +cso=33" which can reduce the voice cracking? Any information ? Share this post Link to post Share on other sites
HetalDP 947 Report post Posted February 6, 2007 First thing to look is the Coverage. Are you have Better Range in Handset if yes the Problem can be solved. Second thing is if the Coverage is Better But Is the Reliance Tower is Connected with Reliance Back Bon Fiber or Any Old Method like RF Link Between the Towers. Older RF Link to Connect Tower to Nearest Fiber also Make the Internet speed slower Share this post Link to post Share on other sites
Anil_S 6 Report post Posted February 6, 2007 Is there any way to reduce the speed & compression ? I feel higher the speed, cracking problem is more. If the speed is arount 70-80 kbs the voice quality & video quality is poor , but voice doesn't crack. Higher the speed, the video & voice may be better bit it cracks.

HetalDP 947 Report post Posted February 6, 2007 No Way Lower the Speed means stable Speed Higher means Burstable Packet which some suddenly and als stop suddenly Share this post Link to post Share on other sites
deepu 0 Report post Posted February 6, 2007 (edited) I have been using Google talk / skype / yahoo on a 64 kbps VSNL connection for the last 9 months and till now has absolutely no troubles. Infact it has been excellent and even better than ISD calls!!!! It will work fine if the throughput remains constant and on a broadband connection it will remain constant Edited February 6, 2007 by deepu Share this post Link to post Share on other sites
anujit 0 Report post Posted February 6, 2007 (edited) yeah exactly deepu. It isnt peak speed thats an issue here. its (in)consistency that phucks up a voice call. In a voice call, every packet counts... drop a few and there goes the call. EV-DO is a next gen technology that won't be launched in India till mid 2008 at least.

Anil_S 6 Report post Posted February 7, 2007 (edited) How do I reduce speed, so that data transfer is consistent. Any strings or settings for modem to connect it with a lower speed & less compression ? Edited February 7, 2007 by aksha_sail Share this post Link to post Share on other sites
HetalDP 947 Report post Posted February 7, 2007 Exactly anujit. Quality / Stability Matters normal Air Interface Based Interenet Service Lacks this. EVDO / WCDMA-HSDPA will solve the Problem. Share this post Link to post Share on other sites

I think Reliance will go to Directly WCDMA instead of EVDO as per thr rule If any CDMA have to take Bandwidth in WCDMA then he can not get Frequncy for EVDO Another thing can be Get 3.75 in 2100 and get Only 1.25 for EVDO in Base Spctrum (Any Suggestion from any body) Share this post Link to post Share on other sites
Anil_S 6 Report post Posted February 8, 2007 Please let me know how do I reduce speed & compression so that I can get a consistent connection. Latency in communication I will be able to handle. I only want solution to voice skipping ( some words get skipped) / cracking. Latency in communication I shall be able to handle by using pause between talk Share this post Link to post Share on other sites
HetalDP 947 Report post Posted February 8, 2007 Speed is achieved by so many Things like Coverage, Towers Backbone, International Namdwidth, INternal Opertors Bandwidth, How Much Program in Comuter Accessing Net on COmputer etc. The COmpression is achied by Anaylsing our Own Data. and We dont have COntrol on Both Share this post Link to post Share on other sites
anujit 0 Report post Posted February 8, 2007 (edited) hpnasik: despite similar names WCDMA is actually an upgrade of GSM. Reliance will have to go for some version of EVDO which is a CDMA technology. aksha: lowering your speed wont help in this case... because the problem is that the connection will completely drop at times. Its best to keep an active ping and if you can set the interval to every 5 seconds or so. Edited February 8, 2007 by anujit Share this post Link to post Share on other sites
HetalDP 947 Report post Posted February 8, 2007 Anujit going to WCDMA will better fits into Reliance Stategy' I definatel know WCDMA is a Code Division Tech of GSM Forums, but reliance already testing in in four matros If reliance goes directly to it we wanna have a flood of Handsets.

anujit 0 Report post Posted February 8, 2007 WCDMA isnt backward compatible with CDMA at all. So I really doubt if they're testing it. Share this post Link to post Share on other sites

But I really doubt PINGAPP HAS HELPED. I have also disabled the software compression in the modem properties. The cracking problem has reduced. I need to check it when I go outstation next time If there are any other suggestions, please post.. Thanks......
