Shiva Bandaru 0 Report post Posted November 24, 2005 TATA encourages RUIM. All New phones in TATA have RUIM. Tata has more RUIM phones then Reliance. Nowadays TATA lunching more Handsets, Schemes, Services then reliance and their handsets are afordable then reliance Ratan Tata also eager to implement EvDo and ofered 1500 Crore as a fee for 3G license To telecom ministry. I Think only CDMA operators can bring 3G services to Consumers @ affordable price point. If 3G license go to GSM they chrge very high from subscribers.

SexyGurl 0 Report post Posted November 24, 2005 I think India will have both types of 3G ... by all existing 2G players. So, GSM will provide WCDMA services and CDMA will provide EVDO. CDMA/EVDO is way too better than the hotch-potch for GSM. (cr*p technology) Share this post Link to post Share on other sites
kesav 127 Report post Posted November 24, 2005 But more importantly you WILL get 2.4 Mbps internet connectivity on your 7230 once RIM starts EVDO services. Hehe. That 2.4Mbps isn't dedicate only for you 47976[/snapback] The 2.4 Mbps is the peak speed which each and every individual can enjoy(Current peak speed is 144kbps for CDMA 1xRTT)under scarce load. So don't worry. This is the peak downlink speed which EvDO can support but real time speed may be around some 50% of it under peak load. the uplink peak speed can only around 153kbps but this may improve when next version of EvDO becomes active. Current revision is Revision 0 and upcoming revision is Revision A(products expected mid 2006). The following link will refresh you about EvDO. http://www.lucent.com/livelink/09009403800..._Newsletter.pdf Share this post Link to post Share on other sites

Achilles 0 Report post Posted November 24, 2005 I stand corrected...no incorrected...er corrected...I mean er...uhh..whatever Confused would be the right term to use I suppose. Could we please reach a fair consensus on this EVDO myth Guys Suprisingly RIM delivers on promised speeds. I get a consistant 130+ kbps speed on RConnect. Verzion users on 1xCDMA claim around 90 kbps! So we can probably expect as close to 2.4 Mbps as possible! 48024[/snapback] BTW, anujit u said u get a 130+ with RConnect...How the Hell?!? I use an LG LSP340E to connect and it gives a max speed of 115.2 kbps...or atleast thats what it says in the system tray network connection icon. I get a download speed of 11.5 kbps max when using getright. Please tell me u know a way to increase those limits... or else the only option I've got left is DataOne(BSNL)...and a lot of ppl say that it's crap. Thanks in advance.

anujit 0 Report post Posted November 25, 2005 (edited) Dude dont believe that lil Windows pop-up. Thats all bull. It can be changed from the control panel. I've set mine to show 920 kbps. Instead download a good bandwidth measurement tool to check your speed. There are alot of great tools at downloads.com and pcmag.com. If you get 11.5 KBps (notice the capital B as in KiloBytes per second) thats equivalent to around 92 kbps (kilobits per second). This speed is dependant on server/network load, connection strenght etc. But of course Getright gives you an AVERAGE speed. so your actual speeds might vary significantly! Get a bandwidth measurement utility to check what your max speeds/dropouts etc is like. Most tools give good graphical representations that you can use to check fluctuations. That will give you the best idea about your connection speed and stability. Edited November 25, 2005 by anujit Share this post Link to post Share on other sites

As for 100 Mbps -- My office has 2 T1 lines (each about 2 Mbps) to US. So, total about 4 Mbps. It supports a large office.

anujit 0 Report post Posted November 25, 2005 Thats right. Linux your ethernet cable has a speed limit of 100 Mbps. Doesnt mean your ISP is actually tossing data down it that fast. Things like routers, repeaters and the like determine your internet speed. You're probably around the 64 kbps mark. Share this post Link to post Share on other sites

Does that mean I get all of that speed to browse / download from the internet? Heck no! I get only 6KBps! :| Same will be the case with newer technologies... Understood? No? Let me clarify. The reason that i posted that was to tell that even though EvDO offers a potential speed of 2.4Mbps, we WONT get it. Why? Thats because even current infrastructure in place supports a LOT of speed BUT that doesn't mean that we get ALL of it . Hence, the example of my ISP. SexyGurl, are you ok? I mean you didn't read my post carefully. I already stated that *my* ISP has a 100Mbps LAN BUT I still get speeds of 6KBps (48Kbps). Thats because even though *I* am connected to my ISP's servers at 100Mbps he still alots me only 64Kbps of the international bandwidth... Share this post Link to post Share on other sites

linuxguy 0 Report post Posted November 25, 2005 dude, you can get all 2.4Mbps but the question is whether the operators would want to give you 2.4Mbps INTERNATIONAL bandwidth. They give a damn if you connect to their network at 2.4Mbps or 100Mbps. They will give you only 100Kbps of international bandwidth, then your 2.3Mbps bandwidth goes wasted!

anujit 0 Report post Posted November 25, 2005 (edited) Dude your LAN speed is 100 Mbps. That means the speed of your ethernet card and the speed of your ethernet cable ONLY. Like in a office connection. This is NOT your ISPs speed. Ever seen an ad for a 100 Mbps (from Sify or anyone) connection dude? BUT, BUT BUT if you connect to another computer on your ISPs network (i.e. in a intranet) you WILL get close to 100Mbps! I understand you're saying that network congestion, signal strenght etc will not give me 2.4 Mbps. Thats true. But the ratio will not be that high (6kpbs to 100 Mbps). The reason you're not getting 100Mbps is because: a. You're not paying for it b. Your ISP cannot support it You're probably paying for a 128 kbps connection at best and getting very average throughput. The reason why we WILL be getting close to 2.4 Mbps is because the number of RIM customers using data services is very less. Hence more bandwith and other infrastructure is available on Reliance as compared to Verizon etc. Hence better throughputs. Not at 2.4 Mbps. But given the example they've set with the 144kbps 1x2000 systems, it shouldnt be too far behind! And of course nobody is expecting 2.4 Mbps. Of course there will be some drop in speed due to a million reasons. Does a 56kbps modem give you that speed. No. But that has very little to do with your ISP not giving you 100 Mbps! And Linuxguy: what on earth are you talking about. Most offices (especially BPO & software types) have connectivity of at least 20-30 Mbps! And yes they are running at those speeds and more! Through VSNL. Through Reliance. Through many many other service providers. International connectivity isnt a problem. Its when the damn pipe this the shore (i.e. VSNL's landing stations - since they have a monopoly here over all international circuits) that the problem starts!

linuxguy 0 Report post Posted November 26, 2005 anujit, please take out some time to READ other people's posts. What you and SexyGurl posted AFTER my post is the SAME that I had posted in my original post. Also, you didn't get my point. My point ISN'T that you WONT get 2.4Mbps speeds. My point IS that you WILL get those speeds UPTO your ISP's infrastructure. He will decide whether to give you 2.4Mbps of INTERNATIONAL bandwidth or not. If you still didn't get what I am saying then keep reading... Sify, PowerSurfer.Net, 7Star, Pacenet, Exatt and other ISPs have LANs. These LANs are standard 100Mbps packet switched networks. THIS MEANS I can get UPTO 100Mbps speeds ON THE LAN. While the ISPs offer ONLY 64Kbps, 128Kbps plans. SO my connection which SUPPORTS SPEEDS **UPTO** 100Mbps is reduced to a connection on which I can transfer data INTERNATIONALLY only at 64Kbps or 128Kbps. LAN Potential speed - 100Mbps ISP offers - 64Kbps Similarly, EVDO Potential speed - 2.4Mbps ISP offers - XX Kbps Get it? Share this post Link to post Share on other sites
kesav 127 Report post Posted November 26, 2005 Linux, You've come closer to understanding but in the end you got bit confused. I take your quote and modify and then you'll unseratand. LAN Potential speed - 100Mbps ISP offers - 64Kbps Real-Time speed(depending on network paramaters) - Close to 64Kbps Similarly, EVDO Potential speed - 2.4Mbps ISP(Reliance) offers - 2.4 Mbps Real-Time speed(depending on network paramaters) - close to 2.4 Mbps Hence what we're actually discussing is how close we'll be when EvDO is implemented in Reliance.

WTF? Thats my POINT. Reliance WONT offer 2.4Mbps of INTERNATION BANDWIDTH. Do you even understand the meaning of INTERNATIONAL bandwidth? Will implementation of EvDO in India suddenly install 1000s of underwater submarine cables for Reliance or will it suddenly make reliance feel that we are offering too less to our customers so we should open up the entire international bandwidth that we have regardless of whatever costs we incurr?! The POTENTIAL bandwidth that EvDO offers is 2.4Mbps! THAT DOESNT MEAN RELIANCE OR ANY ISP IN INDIA WILL GIVE US 2.4Mbps OF INTERNATIONAL BANDWIDTH. If you can't STILL understand my point then simply put - You WONT be able to download from you favorite site at 2.4Mbps... Share this post Link to post Share on other sites
kesav 127 Report post Posted November 26, 2005 Dear Linux, Now I know the reason for your confusion, commotion and irritation. If you've carefully read(studied in your case) Anujit's post you should have realized there's no limit of INTERNATIONAL BANDWIDTH as you've imagined for yourself. The reason you're not getting 100Mbps is because:a. You're not paying for it b. Your ISP cannot support it And Linuxguy: what on earth are you talking about. Most offices (especially BPO & software types) have connectivity of at least 20-30 Mbps! And yes they are running at those speeds and more! Through VSNL. Through Reliance. Through many many other service providers. International connectivity isnt a problem. 48178[/snapback] Its only your service provider not providing the bandwidth. The core routers in the backbone of our country are working at the speed of 2.5 Gbps so provding mere 2.4 Mbps is not a problem at all. The broadband service are aiming for providing the speed upto 8 Mbps with existing infrastructure. Just because your ISP is providing you 64 Kbps, doesn't mean that is available limit in India. So there's no need of any extra submarine cables or anthing like that to provide you this speed. Share this post Link to post Share on other sites
