Infineon Chipset May Be Cause of IPhone 3G Issues
JagsLive sends along a CNet blog piece about a plausible theory to explain the iPhone 3G connection problems many users have experienced. Apple has not acknowledged any such problems. "Richard Windsor of Nomura published a research note... 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.'"
Crap testing is the cause of iPhone 3G issues. There are always issues before a product is released. The testing is supposed to find them. Something as obvious as this issue indicates that Apple didn't give a shit about testing.
I have no idea what connection issues they are tal
I knew i shouldve waited.
Again bitten by Jobs's first-out-the-door gizmo.
I was also the proud owner of a tibook 400... yeah, the one that spontaneusly broke appart from heat due to the "TI" part (although it did look cool at first).
I guess some of us will never learn.
NO SIG
Can this be fixed by a firmware update? It said something about the stack which made me think firmware, or is it just shoddy hardware?
I guess some of us will never learn.
Not your fault, it's genetic.

It reminds me of ATT...... I have had the same issues no matter what ATT phone I've used
Apple might know a thing or two about industrial design, but they don't know anything about microwave engineering. The phone has a very badly designed antenna.
This is also one cause of the short battery life, since the phone has to broadcast at high power levels to make up for the poor gain. Talking on the iPhone is like sticking a microwave oven to your face.
Sorry... Apple says "It just works." so obviously, no one is experiencing these things and it's all a bunch of lies spread by Microsoft.
...and what qualifications does he possess to comment on the possible cause of the alleged iPhone reception issues?
Seriously. This story is being widely distributed, but I have yet to see anyone ask about his credentials. Is he an electrical engineer with expertise in the design of cellular technology?
As far as I can tell, he's some financial analyst. So why would anyone consider him a credible source? Since when are the speculations of a financial analyst regarding the rather esoteric realm of RF engineering considered valid.
Am I missing something? Does someone know about his background?
can you iPhone people just ATH and drive?
Fascism trolls keeping me up every night. When I starts a preachin', he HITS ME WITH HIS REICH!
Do you think service providers are going to refund?
You are paying for a service and a phone which is faulty. Under a contract, does this mean they are failing to proving service and a owner could leave the contract?
I know myself, I only use the phone for a few numbers and they have all dropped no matter when I used the phone thus far...
I have noticed a lot more dropped calls on the iPhone 3g. Between the poorer battery life, the dropped calls, and the inability to unlock the sim, the upgrade feels like a downgrade from my old iPhone.

Good. I hope Infineon goes friking bankrupt and dies.
They are one of the manufacturers of Trusted Platform Modules.
That puts them right near the top of my shit-list.

I've been getting better reception on my 3G iPhone than I had on my Razr (also 3g)
Battery life is pretty crappy, have to recharge it every night. But that's all I need. I think that has more to do with the big honking screen than any chipset issue.
I have noticed that the signal indicator likes to sit at around 1 bar, but it's a bit deceptive because it works fine for a while (feels like empty on a car... still goes for a while anyways)
I know an anecdote isn't true for everyone... maybe he's in a bad signal area? Maybe he has a defective phone? I haven't seen what he's talking about.
I have developed a truly marvelous proof of this comment, which this signature is too narrow to contain.
AT&T has the best network around - More bars in more places. So this flaw should never be visible to the end user...unless AT&T has been lying to me.

I have zero sympathy for those that buy a technically inferior product without evaluating it because it happens be made by their favourite company (which has never treated the customer right in the first place). If intelligent people choose to become members of the cult of the turtle neck, buy an overpriced technically inferior phone missing features so common they are considered industry standard, and overpay for the usage charges because brand loyalty has driven demand through the roof, nothing is going to protect them from their own stupidity. There's more to a phone than a gimmicky interface more suited to a mp3 player.
Keep your faulty iPhones, I'll stick to my Nokia 6220 classic which I researched to death before buying (and which still has the odd quirk but nothing I can't live with and only one minor bug I wasn't aware of when I bought it). No brand loyalty here by the way. I turned down spending an extra $20/month on an n95 8gb despite some nifty features, because the piece of turd only does USB 1.1. I wanted a phone not a sad gimmick. It seems phones will do everything these days except make voice and video calls properly.
I expect this to be modded flamebait, but everyone that does that knows what I'm saying is true, and I'm certainly not just intending to aggravate people. I'm just sick of intelligent people feeding companies that will turn around and fuck them.

...my el-cheapo Nokia 1100 is looking better all the time. Works like a champ, and the battery seems to last forever!
It certainly must not be Apple's fault. I'm sure it is caused by someone less cool.
I've had tons of connection/signal and dropped call problems ever since I upgraded my old non-3G iPhone to the 2.0 OS. I think this is a software problem.
(aka apple-gadget)
How clever...
I was involved in a project that required an Infineon chipset. They had to support to *DSL variants: HDSL and G.SHDSL. After numerous delays, the HDSL had to be dropped because I kid you not: the powers that be at Infineon grossly underestimated the amount of work to support the additional protocol. The head of the design team seriously thought that it was just going to be a matter of changing some parameters...
They deserve every bit of bad news that they get...
Hahahahahahaha...
It's because Batman installed his tracking transmitters in every cell phone in the world. That's why reception is spotty.. duh!
Are we talking about issues in the US where 3G isn't exactly great or Europe where it has been around longer?
I think the 3G chipset problems and all these 3G phones failing back to Edge has made my iPhone V1 drop more calls and suck more. I never got great Edge reception at my house but since the 3G came out my phone drops calls all the time.
hey, have some balls and don't post ac.
...
I experienced a similar issue for a few days in Canada with the Fido and others with the Rogers 3G networks shortly after the July 11th launch. Within a few days, the problems mostly went away where I live and now I get great reception even at work.
There may be a few faulty 3G iPhones but this is mostly caused by a combination of faulty AT&T sims and problems with their network stability and capacity.
Jesus was a compassionate social conservative who called individuals to sin no more.
I work in the industry. I know AT&Ts' 3G network is new and really unproven. 2G service is way more reliable. I have a BlackJack and when I have it set to 2G I have awesome coverage with no problems. With my blackjack on 3G I get dropped calls. Jerky sounding calls. All with full signal all over town. I've tried other 3G phones with same results. I think this is common for any new network that hasn't worked out all its blemishes.
This is not an iPhone chip issue. It is a network issue.
Can't blame Apple.
But we can blame the stuff that Apple chooses.
The the winner (Apple) goes the spoils, but to the problems go the companies that deal with Apple (Infineon). Shame on Infineon for not making sure Apple succeeds.
Little known fact: Anyone who uses the phrase "Apple Fanboy" is in fact either a Microsoft Fanboy, Linux Fanboy, Nokia Fanboy, HTC Fanboy, or Sony Fanboy.
Living in same spot 10 years, always spotty reception on att ( also had for 10 years, first att, then cingular, then bellsouth, then att) and always spotty reception.
My last 3 Sony-Ericksons had the same bad reception, but at least I was ALWAYS able to make calls, staticy, but i cold make and receive them. Had maybe 5 -10 dropped calls ever. ALWAYS able to make calls whenever, wherever.
Now fast forward to the present iphone 3g and I go sometimes 5 minutes with that frackin Call Failed.... crap. Already had at least 20 dropped calls.
I want to throw the iphone through the iwall.
But I wont cuz the internet and stuff is like so cool on it, so I will put up with it. Just like every other person who is experiencing this drop call issue.
NO ONE will return the iphone to go back to their blackberry or whatever.
OVERALL the best personal tech experience I have EVER had and I know a lot of other peeps who feel the same way. ( and REAL peeps, not internet chat room forum, wow clan peeps. real flesh and blood peeps.)
Troll much?
Go to Apple forums and do some research for yourself.
There have always been issues with any product. The difference is in how well the company deals with it (remember MobileMess?), and how its fanboys defend it (just look in the mirror).
Nope. that award goes to gizmodo - Brian Lam and Adam Fucci are seen a lot in the Job's bedroom according to an Apple insider. Wait for gizmodo scoop on size of Job's dick and weight of his balls.
In order of level of accuracy we have:
He may not be an expert in the field. Statistically, pulling a name at random out of the phonebook still has a greater chance of finding the right person than a company denying that there's even a phonebook.
The reality is that a large number of people are having problems with dropped calls, a very large number have significant problems with response time (particularly, it seems, if they've largely filled the device), and almost everyone are having problems with the device locking up and needing semi-regular hard reboots. Even first gen iPhone users who've upgraded to the 2.0 software are complaining about many more issues but at least they can revert - something not open to 3G users.
My guess, and I'm just a programmer/nerd and not a qualified phone engineer, is that it's a combination of newly sourced and poorly tested parts running in a major OS recode that also didn't get the level of testing any other wider ranging OS would get (they couldn't run a beta because Apple have a bitch of a time with leaks and cling on more tightly to avoiding them than most companies).
I may be right, I may be wrong. Statistically, whether the cat is dead or alive in the box, guessing about its state will sometimes be right. Apple's policy of keeping quiet and pretending there's no cat, no box and quantum states only happen to other companies ensures their answers are worse than other people's guesses.
I like how this got moderated to +5 Insightful then immediately moderated as 'Overrated' down to 0. Apparently the moderators know more about RF engineering than me. But hey, if you don't believe me put the iPhone antenna into SEMCAD or any friendly EM modelling software and find out for yourself.
How is this a troll? Read the thread and see for yourself.
interesting...
------ no thanks... I've quit
so this mean, ask before you try ? i'm waiting for the 20gb one.
This bozo hasn't even determined if in fact it's an infineon chipset for sure ... much less he's the same tool that made dire predictions about the touchscreen "wearing out" before the first iphone even hit the shelves.
There might end up being something to a bad chipset, but right now it's *pure* speculation.
Nvidia should have conducted more testing on their GPUs, especially their mobile chips.
I'd love to understand how the SIM causes dropped calls. Can you please explain?
I thought the whole point to apple OVERPRICING their products was because of the "extensive" testing that they do and everything just works. Apple is nothing more than NGM$ (New Generation Micro$oft) Until people pull Jobs out of their arse and see this, they will just get worse. Why, because if people buy it, why change?
Apple creates a good products -- some time. None the less most of their products are expensive -- way more expensive then they should be. I paid for my Mini-Mac over $1000 Canadian dollar, that just is not right. Why? Because values of Canadian dollar is higher therefore Mac - Mini should've cost me no more then $400. This has been pointed out many times by many people in media -- even by mac-heads freaks. No one can deny that OS-X is a wonderful operating system -- compare to Vista. And it's Unix core gives it a very strong security. Non-the-less we are paying very too much for the hardware. And TPM chip software consumes way too much resource. TPM is design to prevent OSX running on a typical x86 hardware. Their behavior is not only illegal but unethical.
Those of you who are not aware of TPM. Think of TPM like old South African government -- White didn't want non-white to have same right or live in a same community. The same way Mac doesn't want non-mac x86 to have OSX. So they created a software which will make sure osx only runs of x86 with TPM chip. TPM is an Apple version of apartheid.
Apple is an evil twin of Microsoft.
Even veals have more autonomy!
LOL, more disillusioned Apple fanbois griping about their silly toy being a fancy paper weight.
Swears he has never had any dropped calls or crappy connections since he has been using his iPhone and he keeps telling me that these stories are just all lies (ok he's a bit of a zealous nut) but honestly, other than the news I know three people with iPhones and they haven't mentioned any significant issue.

I'd love to understand how the SIM causes dropped calls. Can you please explain?
Apparently some of the older sims handed out by AT&T were not properly registered to allow access to all 3G cell towers. This is what certain AT&T users were saying. As a Canadian on Fido, I can neither confirm or deny whether this was true or not as the Canadian problems were exclusively network based.

Always wait for the 3rd generation of any tech product...I'll by my iPhone next year. Thank you beta testers!
Not just ATT. When I upgraded to the iPhone 3G I was still using a sim from a couple of years ago. Many problems ensued, partly because of the SIM and partly because of T-Mobiles innabillity to set up my account properly. Since my SIM upgrade, almost all of the issues have been resolved. Except for the crappy coverage that is. But that's been a problem with T-Mobile Austria for ages...

Meanwhile in The Netherlands (a good testbed, a small country with many iPhones) several iPhone users have been complaining about '3G network coverage problems' with the licensed Telecom Operator (T-Mobile NL).
In a note, the latter blames the problem to the iPhone, suggesting to keep an eye on the future patches and upgrades from Apple.
I personally own a Nokia 3G phone for 3 years already (it can do video calls, too) with the same operator. I can testify I never ever had 3G coverage issues or 'disconnections' in the land.
Oh, and my Nokia never calls back home..
T-Mobile Reference:

Short translation:

2. "When the iPhone switches between 3G and 2G the connection is lost when using certain applications"

There is never anything wrong. Never. No connection problems, you're internet isnt broken when you call - you just want to speak to customer service reps in India for the FUCK OF IT... There's never any problems with anything people complain about anymore.
What a sad fucking world this has become. Stop complaining, your phone that doenst connect is MADE to be like that. Its a paperweight when it isnt working, didnt you know that? Its part of its design.
Screw everyone.
the iPhone's 3G runs on the same frequency as the RDF
since the RDF is much stronger calls get dropped
MacBook pro still suffers several "unacknowledged" reliability issues from both software and hardware (poor wireless connectivity, wake up freeze after suspend, lot of HD failures, ...). This is shameful for the price of this device.
So, this is not really a surprise, especially considering the "unacknowledged" fiasco of the Atheros wireless chip in the MBP.
This is not surprising as the Infineon 3G chipset solution has never really been tested in the hands of users
It would seem that early adopters are becoming the new testers for consumer hardware. And since I am not an early adopter.....
I thank all of you for making my experience so much better a year from now when I buy v2.5 of the hardware.
I've done extensive research on this (I'm a member of the Apple Consultants Network), and I think there may be something to it.
There are a couple of threads on the Apple discussion forums which are well over a thousand posts in length of people saying "me too!" regarding poor reception. The interesting thing is that it includes people all over the world, which indicates it isn't just a problem with AT&T. It looks to me like a software/hardware issue with the phone. Every iPhone 3G which I've seen so far has serious connection issues in areas where other 3G phones are working fine--even other AT&T phones.
I'd post links to the relevant items, but I'm posting this from my iPhone 2.5G, so I have no copy and paste yet (sigh).
I'd say almost without a doubt, it's the 3G network itself. I work for a handset manufacturer and we have a fairly good 3G network in our metro, but coverage is still spotty at best. One of the reasons Apple went GPRS/EDGE was not just for battery, it was the network coverage. Ugly fact AT&T doesnt mention is 3G is not quite prime time yet. It's getting better, but it's not going to happen overnight that it will reach GSM coverage levels.
I've been hearing these complaints from iPhone users and it's not the iPhone or Infineon's fault. I call it the "teetering on the edge of networks" bug because it happens when 3G's around 1-2 bars while edge is around 3-4. It appears that the phone's trying to get the best possible connection but when 3G and EDGE are about the same, the phone will switch between networks, often repeatedly, causing dropped calls, download problems and whatnot. This is all assumption, but I've been privied to enough to AT&T phones to feel I almost hit the nail on the head here. I only wish there were a "to hell with 3G" option available on any of these phones so I could confirm my theory.
Charisma is the measure of someone's ability to lie with a straight face.
Apparently some of the older sims handed out by AT&T were not properly registered to allow access to all 3G cell towers.
This is great info, as someone who has myself experienced repeated dropped calls while using my iPhone 3G in my living room. (Friends tend to start making fun of your new iPhone after they get dropped four times during a single conversation.)
The question is, how can I know whether I have such a SIM in my iPhone?
"We can categorically state we have not released man-eating badgers into the area." - UK military spokesman, July 2007
This is an issue for a large production product...
I see a lot of people of fanbois running to say all products have glitches blah blah blah...
This is a large production product and it is not an 'only' nor even a 'new' technology...
You can get a 4yr old Razr or 715 or even a free Samsung R500 at Walmart that have outstanding 3G reception, and this is the 'cheap' stuff, not even a pocket PC or pda class phone device.
Apple 'pretends' to be better or provide a 'better' product, but it isn't reality anymore, and hasn't been for years and years. They are more of the 'me too' crowd and when it comes to hardware quality, they will buy the cheapest crap they can find making even model to model have different LCDs, GPUs, or chipsets on their computers because they get a 'deal'.
They have gotten way too much of a free ride on SlashDot because of Darwin, which is now nicely closed up in all important areas, and in their products and business practices they make Microsoft look like the 'nice' consumer friendly company...
Apple is a company about WOW. Steve Jobs can sell ice cubes to the North Pole. Just call them iCubes. But seriously, Apple is all about the sales pitch and a few features that WOW the average user and Apple FanBoy (which does'nt take much). The real fact of the matter is Apple's are no better or worse then anything else.
It's just that they cost more. That being said, Apple needs to bring profit margins down and get product prices in line with the rest of competition. I think we can safely say that the ideal of Apple being worth the extra price is going away fast.
It's actually the opposite with the iPhone. In my house I get spotty AT&T reception. But if I have my phone in EDGE only mode, I usually will only drop a call if I go in the basement. With 3G turned on, if the Phone decides it wants to use the 3g signal when I am calling someone or receiving a call, it is almost guaranteed I will drop the call. The phone refuses to switch back to EDGE.
I've had mine for about 2 weeks now. Today was the 4th time my phone would go into 'No Service' mode. A restore doesn't help, and the phone will spontaneously re-connect to the network after a few hours/days of being down. I've just set up an appointment with my local Apple store for them to look at it (and hopefully replace this lemon). As an 'upgrade' to a Treo 700w, I'm starting to regret my purchase (Not only do I get these downtime issues, but their current Activesync/Exchange implementation is atrocious (compared to the WM platform).

I'm using a Nokia N95 in a german UMTS network, and i have exactly the same problem. The phone can't do a handover from UMTS to GSM, so when the signal gets weak, phone calls drop. This, for example, happens every time i'm driving out of my city (my network doesn't serve 3G on the countryside).
I find it interesting that for data connections handovers do work.
