O2's network in London strained by data intensive iPhone owners

Like I've been saying all along. Take the iPhone to Verizon and they'll feel the pain too. I can only hope they get it so all the fanboys feel the karma.

You're cursing him out just because of what he just said. That's pretty sad.

that isn't a curse bro...if he said FUCK YOU HOVA. that is cursing. :-). too bad for the english.

It could... but probably not. I work with HSPA and CDMA networks all the time for chipset designs for both platforms. CDMA can on average handle 10x the bandwith HSPA networks can. So even if every single iPhone user jumped ship to Verizon for example, it would not create as much of issues as AT&T is currently having. Don't get me wrong, it probably would suffer at times, but nowhere near what it does to a HSPA network. The main thing is, In reality. Not everyone would jump ship. So it would eliminate some stress off them, but even taking on half Verizon's network would handle the bandwith better still. LTE is great is because it takes the best things from CDMA and UMTS and combines them creating an awesome infrastructure LTE is backwards compatible with CDMA and UMTS and will transfer seamlessly Contrary to what people believe LTE is not a GSM technology nor GSM. Just taking fundamentals from both with LTE revision 8 that will launch with most carriers world wide.

In theory I see what you're saying. Only problem is it hasn't actually been implemented to see exactly how well it will work. It will be interesting to see if Apple does come out with an LTE iPhone and what it will do to VZW's network.

Thanks for giving useful information as usual SIN. You are def a wealth of information and provide good insight. You sill work for Qualcomm?

hova, I still doubt it. I don't know if you remember. A few months ago there was a similar article and we were doing network strains on chipsets when I was up in the San Francisco Bay Area (San Jose actually) and Verizon and Sprint had the least amount of network loads during peak times. (4pm-7pm). Verizon's network operating load was 12% of capacity (out of 100) on the EVDO Rev A, Sprints was 16%, T-Mobile HSPA (Testing 21mb future cell site) was 22%. Where AT&T's HSPA+ was at 78%. We tested a Verizon LTE site and tried to max it out and could not. We had threw 23.x times more bandwith at the LTE site and it took it like a champ on a 700mhz spectrum. Even with 23 times more simulated users, we achieved way faster data speeds than Verizon or ATT network speeds combined. We were able to surf at consistant 6mb+ speeds. It's hard to say, as I don't care too much about phones or companies. But Verizon was smart to buy most of the the 700Mhz block for LTE. It's going to put them in a good position. Thanks Latin, yeah I still work at Qualcomm. I have too many shares and years with them. I'll be here till i'm rolling around in a wheel chair bitching about how I have to go test a 8G network. lmao

That sounds pretty impressive. My only thought is what about all the areas where LTE won't be available for quite a while? From what I understand it's backward compatible so won't LTE handsets leave heavy strain where LTE hasn't been expanded? For instance if they did come out with an LTE iPhone? Based off previous data network expansion I would assume it will be mainly in large citis such as San Fran where you've been doing testing so far.

LTE deployment takes beneifits from CDMA being a spread spectrum technology. Where most cellular towers penetrate 2-8miles depending on environment. LTE towers can achieve up to 15 miles, while also putting out a strong frequency. For instance. We tested an ATT tower on top of SF General Hospital, and it was on 1900mhz HSPA, which will cover more area but not penetrate as hard as 800Mhz, So the frequency was swapped in favor of the 800Mhz, because the surrounding area was covered well, but people in the hospital were not getting good coverage. It's an easy fix. Now Imagine, the bandwith capabilites of LTE on 700Mhz. Way further connections (So less towers needed initally) and can also penetrate easier. LTE will soft hand off back to a CDMA or HSPA network. So if a customer was on LTE it will fall back on HSPA/CDMA and the consumer could have no idea except for an indicator on his phone. Once ATT gets on the ball with LTE, both networks will be very comparable except the fact that where there is only HSPA and CDMA. HSPA users will still continue to be able to use voice and data at slower 3G speeds. CDMA obviously will only use Voice or Data. But LTE allows the carriers to dump data on LTE network and have they're older services used exclusively for voice. So ATT and Tmobile will always have the advantage if there is just existing 3G services to use voice and data at the same time. It's dissadvantage is how much more spectrum Verizon bought. It's almost double of what ATT and Tmobile bought combined. So I personally think it's going to be a similar situation now in a couple years. Not sure why ATT says it's better to invest higher speed 3G network now and focus on LTE when handsets come out. I find this odd, because there is only a handful of phones that actually are capable of 7.2+ or higher. I make chipsets and don't have any orders for hardly anything above this. So why not go Verizon route and leave it alone, get the jump and start LTE with them. So Verizon doesn't lash out again with a huge nationwide network and then we see these stupid adds all over again. That's just my opinion. Either way I'm getting paid on people having high demand on new phones...which means new chipsets....which means my wife will be happy when our pool gets put in and finshed by May this year.

I guess it isn't just AT&T's network. Any network that has the mass of iPhone users won't be as pretty and perfect as it was before. Good luck Verizon...

well my sister in spain told me that the iphone on moviestar spain never has any problems .. like the ones at&t and o2 are having so idk what to think .. she told me she did a speed test in madrid on 3G and that she got 9mbps up and 7 mbps down so yea..

Why are people blaming the IPhone Obviously this will happen on any carrier with smart phones becoming more popular everyday. With all the apps, GPS, ..ect that's also growing it's growing to strain any network EVEN VERIZON The problem with Verizon is, until just a few months ago their smart phone selection was Blackberry, Palm, and Windows phones. Which to me don't seem to be as data hungry as Android phones and the Iphone. Double the amount of Droid customers on VZW to match that of AT&T's Iphone users and I'm sure VZ wouldn't be perfect either. I do find amusement in the thought of putting the Iphone on Sprint's network. *lol*

@homotechtual u said that the iphone will mess up any network obviously that is not the case cause it has not happened to movistar spain. cause my sister said she uses her iphone 3Gs all da time even at 12 in the day when obviously there is a lot of people on da network and that not once has she ever gotten call failed or a dropped call and she usually always get 5-10 mbps when she does a speed test she said that its very rare when she gets less than that. . also i told her about the crappy networks we have in america like at&t ( i live in new yorK) were at&t is horrible and she started to make fun of me .. i have verizon which is real good in new york i have a droid and not once have i ever gotten 5mbps when ii do a speed test the most i have ever gotten is 2-3 mbps ..my sister said that she has never ever gotten 2-3 mbps . she said over there everyone gets 5-10 mbps on average everyday at whatever time of the day.. also all their other phones have video calling which we dont all of their phones have a front facing camera .. like for example the samsung omnia 2 over there has a front facing camera and the samsung omnia 2 from verizon doesnt ...
