Analyst: Infineon chipset possible cause of iPhone 3G issues

The 3G reception problems that iPhone 3G owners have experienced might be chipset-related.

A financial analyst believes Apple's iPhone 3G reception issues may be the result of some faulty chips.

Richard Windsor of Nomura published a research note (spotted at GigaOm) Tuesday singling out the iPhone 3G's chipset, made by Infineon, as the probable culprit for the reception problems we reported on Monday. The dropped calls, service interruptions, and abrupt network switches experienced by iPhone 3G users reminded Windsor of similar complaints five years ago, when 3G phones were first launched in Europe.

"We believe that these issues are typical of an immature chipset and radio protocol stack where we are almost certain that Infineon is the 3G supplier," Windsor wrote. "This is not surprising as the Infineon 3G chipset solution has never really been tested in the hands of users. Some people will not experience these problems as it is only in areas where the radio signal weakens that the immaturity of the stack really shows."

The problem for Apple is that if Windsor's theory is correct, that would mean a firmware upgrade is unlikely to solve the problems, he wrote. The problems might be confined to a certain build of iPhones, or a certain batch of chips, but "this shows the risk of not going with a tried and tested solution."

An Infineon spokesman declined to comment on anything iPhone related, but said he would check into whether the particular chipset used in the iPhone 3G had been used in other phones. Apple has refused to acknowledge any issues with the iPhone 3G.

Memo to Joe Testa,

I never had these problems with my 3G iPhone. have you ever owned a smartphone at all?

Windsor is the same analyst who theorized that the iPhone EDGE touchscreens were susceptible to heat, and could degrade within 4-6 months, and, more ominously, were not fixable except by complete replacement.

Sound familiar? You might want to check when Windsor retracted that erroneous report as well to his clients, to assure them that 1) he was wrong about the chemical composition of the iPhone screen 2) he was wrong about the screens failing within 4-6 months.

Oh, nevermind, he didn't.

I have posted Steve Jobs, all the way down the list, email addresses and phone numbers on my website www.fixmy3giphone.com

Everyone send Steve and email. There is a link that proves he listens!

Cnet, if the post of my site is not allowed I apologize. I AM directing all traffic from my site and forums to your site for your MHz test.

Keep us all posted on any info! Your're great!

Why? So his secretary can delete the messages?

Seriously, this kind of response is old and proven not to work.

I dont even give a crap. People who try to talk on 3G seriously need to check their heads anyways. Everyone already knows the 3G iphone has terrible battery life. The primary reason to use 3G on any phone is that the extra bandwidth can be used to browse the web or check email during a phone call. This is absurd, since the battery would give you even LESS than the 5 hour estimated talk time on 3G. Here's a solution: Make a call on edge, then connect to a wi-fi network. Problem solved.

Deft, if you mimicked an Apple commercial then I would agree, but you DONT. Far from it.

Sure, where's the nearest coffee shop so I can get wi-fi?

Problem I have is that I can't actually call my brother with 3G turned off. It definitely seems like an isolated issue which i only found yesterday so I'm going to look into it, but nonetheless i need 3g turned on for now to talk to him. if its turned off i just get a "call can't be completed as dialed" when i call him. its weird and i can't find anything about it on the web so far. luckily i receive calls from him fine with it off, so i do turn it off most of the time.

I'd wager that most of the problems are due to incomplete buildout, not the phone.

I'm getting pretty tired of reading this reply. If it's true, why can I do a side-by-side comparison between my old Razr V3xx and my new iPhone 3G, and see with crystal clarity how much better the signal level and call/data connections are on the Razr?
by dehall622 August 12, 2008 12:35 PM PDT
If the problems were exclusively with the phone, all iPhone 3G users would be affected. This is not the case.

If the problem were exclusively with a carrier, all phones of that carrier would have issues. This is not the case.

The most likely situation is a combination of poor coverage (especially in places where the AT&T map shows coverage) combined with a weaker-than-most 3G antenna in the iPhone.
by RainCaster August 12, 2008 1:08 PM PDT
Huh? My HTS phones have worked great for 2 years now on the AT&T network. They have far faster service than I would ever get with the 1 megabit flavor of "3G" that Steve & Company are pedaling. This is not an issue of the Phone company, as GSM is very old technology and quite well understood by Samsung, HTC Motorola and Nokia. It's only Apple that has problems understanding industry standards.

This would be unbelievable if true...I think I want to return my iPhone 3G I just brought this weekend and wait until next year or 4G!

What's unbelievable - that a brand new network and a brand new chipset might not work perfectly?

Yeah, and I remember when you would be using the huge old brick cell phones and you'd get 100 miles out of the city and it would lose service. Just as unbelievable.
by reddawnz August 12, 2008 12:06 PM PDT
Why is it that no one can come up with a phone that stays on the edge network untill you want to browse the web and then switch to 3g for web useage. That would give you the better signal of edge (penetrates walls better, much better build out), better battery life and connect to 3g when you open up internet explorer / safari to take advantage of highspeed data. Wouldn't that be the best of both worlds?

This is exactly what sprint+verizon does. rev A (aka 3.5g) only for internet and when requested by user. Sprint should be out with 4g by the end of the year. I had the new iPhone for 3 weeks and it just wasn't for me (personal/business user). I am staying with my treo on the powerful sprint network. At&t didn't build their network from the groundup like sprint/verizon. My friend work for At&t doing beta testing from cali to brazil back to nyc and the internet connection was terrible compare to sprint, and yet 3 months later At&t roll out their network to the public.

"A financial analyst believes Apple's iPhone 3G reception issues may be the result of some faulty chips." Hear hear! Since when did financial analysts get the expertise/training of doing design/fault/engineering analyses?

there is physical evidence that hand position makes a difference in getting weak Edge/3G signal. Hardware problem? sounds like it to me.

Analysts track the industry closely, I'm glad someone finally shed some light into this. Apple needs to recognize this problem and fix it.

I have to disagree, I had a 2.5 iPhone and currently own and use a 3G. The battery life is just fine on the 3G. However, you have to switch off PUSH. then the battery life is much better. No need to turn off 3G to save battery life.


I support iPhone users in the Enterprise and not one has an issue with battery life when it comes to the 3G. Anyone telling different does not know what they are talking about.

I agree that the battery life is better without PUSH enabled but if you leave 3G on in the Phoenix area the number of bars diminishes to 1 bar or no service. The phone has problems with reception and 3G.
by VelvetHammar August 13, 2008 8:58 AM PDT
Just because you and your Users don't report issues means the rest of us are liars or morons? Get a grip man. I have 3 iPhones. One original launch model, another purchased 6 months later, and now an iPhone 3G. I can say without a doubt the battery life is TERRIBLE on the newest phone. You even admit in your own post that you have to disable a highly promoted feature of the phone to get the battery to last.

You don't know what YOU are talking about.

I have my iPhone 3G since Friday, and I'm encountering some pretty poor network speed when using 3G in Manhattan during the day, to the point that it sometimes not usable at all. Yet to me this seems to be due to perhaps having too many people trying to use that service at the same time and AT&T not being able to keep up? When using 3G in Brooklyn, it works just fine, also when using 3G in Manhattan / midtown early in the morning, e.g. before 8am, it also works reasonable well.

Apple usually produces a pretty good product, I'm not saying everything is perfect, but all and all it seems like they like to produce very intuitive (easy to use) , and well made, high quality products. I think perhaps what went wrong here is that the basic design was already known - it was just different innards, so the upgrade seemed something easy and there seemed little need for extensive quality controls.

This is not an iPhone hardware issue. It is an AT&T network capacity issue. Even people with non-iPhones are reporting diminished capacity. The iPhone was more popular than expected and the additional load on the network is causing issues. There are also reports that some AT&T sim chips are being replaced for some customers. Here in Canada, many of us had issues for several days but they generally cleared up. I did not have to change out my iPhone or sim card which I picked up on July 11th.

Tell that to the iPhone users on Australian Telco (not affiliated with AT&T at all) because they are having the same issues with 3G, if they go back down to 2G they are fine.
by Lance Jones August 12, 2008 4:24 PM PDT
Steve Jobs - I guess the role of a president (be it the Apple or the United States) is to never admit there is a problem. Well, you have about 3 million serious problem and I hope Apple and AT&T are ready to pony-up. These cannot be fixed on a product by product basis like the idiot marketing person at AT&T stated. Your crown jewel could be your demise. I love my IMAC and MacBook Pro but I am really hating this phone. 3G is now off full time.

Lance,

make that 2,999,998 "serious problem" at most. My wife and I are having no problems with 3G iphones so far. How scientific was your poll of the 3 million users?
by Sabroson August 12, 2008 10:21 PM PDT
CNET SAYS: Traffic to our webpage is down.. let's write an article on how bad the iPhone is and that will surely bump it up !!

PUFF !!

Here are the real questions:

How many people are complaining about this problem?
Is it a dozen loud complainers?
Is it 1% of owners? 10%? 20% 50%?

Is CNET going bananas about a problem that is not widely occurring?

Are you guys being alarmist ?

I don't know the figures but if it is only 1% of a million phones (Apple has sold far more than that) that is still 1000 bad phones. Furthermore if it is only a fluke like you suggest statistically then it should clear up very quickly as those 1000 users replace their phones. From what I have read of user's experiences with replacing the phones they still have the same issues.

I don't think anybody is being alarmist, except you.

I bought an Iphone 3g two days ago, and the 3g recption, is most of the time, one to two bars. It also also performs better in 2g mode.

Since finding out, that the antenna is at the bottom of the Iphone. When turning the phone around, my signal increases to full reception.

I have to say, I have been dealing and fixing mobile phones for years. This is the first time I have come across, an antenna installed at the base of the phone. Where the users hand is placed sheilding the signal, from working. This phone was tested on the Optus 3G 2100 Network Toowoomba QLD Australia.

iPhone 3G uses two antennae integrated into some unexpected places: the metal ring around the camera, the audio jack, the metal screen bezel, and the iPhone circuitry itself.

As a long time Apple customer, both personal and professional, I find my recent experience with the iPhone 3G and MobileMe to be very upsetting. I can't believe I sold my old iPhone 8GB for this horrible white iPhone 3G 16Gb. Since day one I've had terrible 3G signal strength (in DFW, a heavily covered area), abysmal battery life (with and without 3G enabled, bluetooth off, and wifi disabled), serious interface slowdowns (keystrokes taking placing 15 seconds after typing), and poor ipod performance (slow to respond, forgetting track location, skipping, repeating.) Don't even get me started on the constant need to 'reboot' the phone because Safari and Map crashes.

That doesn't even include all the terrible issues I've had with the half baked mess that is MobileMe.

I work in technology, and understand it's not perfect. But that does not excuse what is obviously an attempt by Apple to capitalize on the iPhone's success and turn out a sub par product.

Come on Apple, admit there's a design issue with this phone, the longer you wait the more of these lemons there will be out there for you to replace.

On the fence about whether or not to get one? DON'T!

I refuse to use my contacts at Apple corporate to get the help I need, but never get from Apple support. Because I want to see what a normal customer would have to suffer through with this product. My experience will heavily influence my future personal and professional purchases, as well as whether or not I continue to be a shareholder.
