Intel Infineon: history repeats itself

Monday, August 30th, 2010

Unlike its perplexing McAfee move, Intel had to acquire Infineon. Intel must make the Atom succeed. The smartphone market is growing fast, and the media tablet market is in the starting blocks. Chips in these devices are increasingly systems-on-chip, combining multiple functions. To sell application processors in phones, you must have a baseband story. Infineon’s RF expertise is a further benefit.

As Linley Gwennap said when he predicted the acquisition a month ago, the fit is natural. Intel needs 3G and LTE basebands, Infineon has no application processor.

Linley also pointed out Intel’s abysmal track record for acquisitions.

Intel has been through this movie before, for the same strategic reasons. It acquired DSP Communications in 1999 for $1.6 Bn. The idea there was to enter the cellphone chip market with DSP’s baseband plus the XScale ARM processor that Intel got from DEC. It was great in theory, and XScale got solid design wins in the early smart-phones, but Intel neglected XScale, letting its performance lead over other ARM implementations dwindle, and its only significant baseband customer was RIM.

In 2005, Paul Otellini became CEO; at that time AMD was beginning to make worrying inroads into Intel’s market share. Otellini regrouped – he focused in on Intel’s core business, which he saw as being “Intel Architecture” chips. But XScale runs an instruction set architecture that competes with IA, namely ARM. So rather than continuing to invest in its competition, Intel instead dumped off its flagging cellphone chip business (baseband and XScale) to Marvell for $0.6 Bn, and set out to create an IA chip that could compete with ARM in size, power consumption and price. Hence Atom.

But does instruction set architecture matter that much any more? Intel’s pitch on Atom-based netbooks was that you could have “the whole Internet” on them, including the parts that run only on IA chips. But now there are no such parts. Everything relevant on the Internet works fine on ARM-based systems like Android phones. iPhones are doing great even without Adobe Flash.

So from Intel’s point of view, this decade-later redo of its entry into the cellphone chip business is different. It is doing it right, with a coherent corporate strategy. But from the point of view of the customers (the phone OEMs and carriers) it may not look so different. They will judge Intel’s offerings on price, performance, power efficiency, wireless quality and how easy Intel makes it to design-in the new chips. The same criteria as last time.

Rethink Wireless has some interesting insights on this topic…

Dual Mode Phone Trends Update 4

Sunday, July 11th, 2010

We are half way through the year, so it’s time for another look at Wi-Fi phone certifications. Three things jump out this time. First, a leap in the number of Wi-Fi phone models in the second quarter of 2010. Second, the arrival of 802.11n in handsets, and third Samsung’s market-leading commitment to 802.11n. According to Rethink Wireless “Samsung’s share of the smartphone market was only about 5% in Q1 but it aims to increase this to almost 15% by year end.” Samsung Wi-Fi-certified a total of 73 dual mode phones in the first six months of 2010, three times as many as second place LG with 23. In the 11n category, Samsung’s lead was even more dominating: its 40 certifications were ten times either of the second place OEMs.

Here is a chart of dual mode phones certified with the Wi-Fi Alliance from 2008 to June 30th 2010. We usually do this chart stacked, but side-by-side gives a clearer comparison between feature phones and smart phones. Note that up to the middle of 2009, smart phones outpaced feature phones, but then it switched. This is a natural progression of Wi-Fi into the mass market, but may also be exaggerated by a quirk of reporting: of HTC’s 17 certifications in the first half of 2010, it only categorized one as a smart phone.
Dual mode phones by quarter 2008-2010

The chart below shows the growth of 802.11n. It starts in January 2010 because only one 11n phone was certified in 2009, at the end of December. As you can see, the growth is strong. I anticipate that practically all new dual mode phone certifications will be for 802.11n by the end of 2010.

802.11n phones 2010 by month

Below is the same chart sliced by manufacturer instead of by month. The iPhone is missing because it wasn’t certified until July, and the iPad is missing because it’s not a phone. With only one 802.11n phone, Nokia has become a technology laggard, at least in this respect. The RIM Pearl 8100/8105 certifications are the only ones with STBC, an important feature for phones because it improves rate at distance. All the major chips (except those from TI) support STBC, so the phone OEMs must be either leaving it disabled or just not bothering to certify for it.

All you can eat?

The always good Rethink Wireless has an article AT&T sounds deathknell for unlimited mobile data.

It points out that with “3% of smartphone users now consuming 40% of network capacity,” the carrier has to draw a line. Presumably because if 30% of AT&T’s subscribers were to buy iPhones, they would consume 400% of the network’s capacity.

Wireless networks are badly bandwidth constrained. AT&T’s woes with the iPhone launch were caused by lack of backhaul (wired capacity to the cell towers), but the real problem is on the wireless link from the cell tower to the phone.

The problem here is one of setting expectations. Here’s an excerpt from AT&T’s promotional materials: “Customers with capable LaptopConnect products or phones, like the iPhone 3G S, can experience the 7.2 [megabit per second] speeds in coverage areas.” A reasonable person reading this might think that it is an invitation to do something like video streaming. Actually, a single user of this bandwidth would consume the entire capacity of a cell-tower sector:
HSPA ell capacity per sector per 5 MHz

This provokes a dilemma – not just for AT&T but for all wireless service providers. Ideally you want the network to be super responsive, for example when you are loading a web page. This requires a lot of bandwidth for short bursts. So imposing a bandwidth cap, throttling download speeds to some arbitrary maximum, would give users a worse experience. But users who use a lot of bandwidth continuously – streaming live TV for example – make things bad for everybody.

The cellular companies think of users like this as bad guys, taking more than their share. But actually they are innocently taking the carriers up on the promises in their ads. This is why the Rethink piece says “many observers think AT&T – and its rivals – will have to return to usage-based pricing, or a tiered tariff plan.”

Actually, AT&T already appears to have such a policy – reserving the right to charge more if you use more than 5GB per month. This is a lot, unless you are using your phone to stream video. For example, it’s over 10,000 average web pages or 10,000 minutes of VoIP. You can avoid running over this cap by limiting your streaming videos and your videophone calls to when you are in Wi-Fi coverage. You can still watch videos when you are out and about by downloading them in advance, iPod style.

This doesn’t seem particularly burdensome to me.

AT&T to open wireless data channel to VoIP

Wednesday, October 7th, 2009

In an earlier post, I discussed a comment AT&T made contemplating allowing VoIP on the cellular data channel. Today AT&T wrote a letter to the FCC saying that they have decided to go ahead with it.

This will make international calls much cheaper for people who are willing to put up with the latency issues of the data channel.

3G network performance test results: Blackberries awful!

Thursday, October 1st, 2009

ARCchart has just published a report summarizing the data from a “test your Internet speed” applet that they publish for iPhone, Blackberry and Android. The dataset is millions of readings, from every country and carrier in the world. The highlights from my point of view:

  1. 3G (UMTS) download speeds average about a megabit per second; 2.5G (EDGE) speeds average about 160 kbps and 2G (GPRS) speeds average about 50 kbps.
  2. For VoIP, latency is a critical measure. The average on 3G networks was 336 ms, with a variation between carriers and countries ranging from 200 ms to over a second. The ITU reckons latency becomes a serious problem above 170 ms. I discussed the latency issue on 3G networks in an earlier post.
  3. According to these tests, Blackberries are on average only half as fast for both download and upload on the same networks as iPhones and Android phones. The Blackberry situation is complicated because they claim to compress data-streams, and because all data normally goes through Blackberry servers. The ARCchart report looks into the reasons for Blackberry’s poor showing:

The BlackBerry download average across all carriers is 515 kbps versus 1,025 kbps for the iPhone and Android – a difference of half. Difference in the upload average is even greater – 62 kbps for BlackBerry compared with 155 kbps for the other devices.

Dual-mode technology maturing

Thursday, August 27th, 2009

The Rethink Wireless newsletter is always worth reading. An article in today’s edition says that according to ABI dual mode handset shipments are on track to double from 2008 to 2010, and more than double from 2009-2011 (144 million units to 300 million units).

Rethink’s Matt Lewis cites improved performance and usability as driving forces, plus a change in the attitudes of carriers towards hot-spots. Wireless network operators now often have captive Wi-Fi networks and can use them to offload their cellular networks.

The upshot is a prediction of 300 million dual mode handsets to ship in 2011: 100% of the smartphone market plus high end feature phones.

The attach rate of Wi-Fi will continue to grow. By 2011 the effects of Bluetooth 3.0 will be kicking in, pushing Wi-Fi attachment towards 100% in camera phones and music phones in ensuing years.

Fixed Mobile Substitution and Voice over Wi-Fi

Tuesday, January 6th, 2009

Getting rid of your land-line phone and relying on your cell phone instead is called Fixed Mobile Substitution (FMS).

A report from the National Center for Health Statistics of the Centers for Disease Control (CDC) shows a linear increase in the number of households that have a cell phone but no land-line, starting at 4.4% in 2004 and reaching 16.1% in the first half of 2008.

These numbers match those in a recent Nielsen report on FMS.

FMS will most likely accelerate in 2009 because of the recession. It will be interesting to see by how much. We will reach a tipping point soon. 13% of households have a landline that they don’t use.

There are about 112 million occupied housing units in the US, and about 71 million broadband subscribers.

So what does this mean for Wi-Fi VoIP? One of the primary reasons for FMS is to save money; it is more prevalent in lower income households. There are two kinds of phone that do VoWi-Fi, smartphones and UMA phones. Smartphones are expensive, and probably less common among the cord-cutting demographic – except that that demographic is also younger and better educated as well as having a modest income – many are students.

Wi-Fi VoIP in smart phones is still negligible, but the seeds are planted: vigorous growth of smart phones, Wi-Fi attach rate to smart phones trending to 100%, a slow but steady opening up of smart phones to third party applications, broadband in most homes, Wi-Fi growing in all markets.

Wi-Fi and the Mobile Internet

Thursday, December 18th, 2008

Admob periodically publishes numbers on the mobile Internet and its usage. The numbers are badly skewed because of Admob’s customer mix. For example Indonesia lists as the second largest mobile Internet market in the world. But if you make your own mental adjustments for this, the numbers are informative.

Admob’s latest report highlights Wi-Fi use in the USA.

Of the ad requests fielded by Admob, in August 2008 9% came from Wi-Fi capable devices: dual-mode phones, iPod Touches and Sony PSPs. In November this number doubled to 19%. Since the numbers for August aren’t broken down, it is uncertain which devices drove this growth, but my guess is that it is due to the booming sales of the iPhone.

Of the requests from Wi-Fi capable devices, the proportion that came over Wi-Fi varied radically. For the iPod Touch and the Sony PSP, 100% of the requests were over Wi-Fi. No surprise there. But on the phone side, a very interesting discrepancy between the iPhone (42% of requests by Wi-Fi) and the HTC phones (16% of requests by Wi-Fi). Since each of the phones uses the same browser for cellular data and Wi-Fi connections, it can’t be an ease of use of the Internet issue. Two other possibilities come to mind: the Wi-Fi may be easier to set up on the iPhone than it is on the HTC phones, or the cellular data speed may be worse on the AT&T network, driving the users to Wi-Fi, while users on T-Mobile (where all the HTC phones listed in the report are) get acceptable performance from their cellular data connection.

The Blackberry data casts a similar light on the question. The two Blackberries in the report were the 8820 and the 8320. The 8820 had the same profile as the iPhone – 40% of the requests came by Wi-Fi. The 8320 had even less Wi-Fi use than the HTC phones – only 8% of the requests came by Wi-Fi. These two phones are both on the same carriers (AT&T and T-Mobile), they have the same Wi-Fi chip (from TI), and their specs are similar.

The clue is in their release dates. The 8320 has been out on T-Mobile for a year, but was not yet released on AT&T in November when AdMob collected their numbers. The 8820 was released by AT&T a year ago, but by T-Mobile only 6 months ago. There are obviously a lot of other variables at work – like 3G versus 2G, for example, and pricing structure, but this looks like evidence that the T-Mobile data network has a more acceptable performance than AT&T’s.

A not so perfect Storm

Wednesday, December 10th, 2008

The Verizon Storm may be heading for failure in more than one way. A raft of reviewers, led by David Pogue of the New York Times are trashing its usability. This means that even with the marketing might of Verizon behind it it may not fulfill its goal of being a bulwark against the iPhone in the enterprise.

But the Storm was an experiment in another way by Verizon. The other three major American mobile network operators have capitulated to Wi-Fi in smartphones. Against the new conventional wisdom, Verizon decided to launch a new flagship smartphone without Wi-Fi. The Storm looks like a trial balloon to see whether Wi-Fi is optional in modern smartphones. If the Storm is a success, it will demonstrate that it is possible to have credible business smartphones without Wi-Fi. But if it turns out to be a flop because of other factors, it will not be a proof point for Wi-Fi either way.

But Wi-Fi is a closed issue by now for all the network operators, perhaps even including Verizon. Phones have lead times of the order of a year or so, and controversies active back then may now be resolved. Verizon covered its bets by launching three other smartphones around the same time as the Storm, all with Wi-Fi (HTC Touch Pro, Samsung Omnia, Samsung Saga).

Before its launch, AT&T hoped that the iPhone would stimulate use of the cellular data network. It succeeded in this, so far beyond AT&T’s hopes that it revealed a potential problem with the concept of 3G (and 4G) data. The network slows to a crawl if enough subscribers use data intensively in small areas like airports and conferences. Mobile network operators used to fear that if phones had Wi-Fi subscribers would use it instead of the cellular data network, causing a revenue leak. AT&T solved that problem with the iPhone by making a subscription to the data service obligatory. T-Mobile followed suit with the Google phone. So no revenue leak. With the data subscription in hand, Wi-Fi is a good thing for the network operators because it offloads the 3G network. In residences and businesses all the data that goes through Wi-Fi is a reduction in the potential load on the network. In other words, a savings in infrastructure investment, which translates to profit. This may be some of the thinking behind AT&T’s recent acquisition of Wayport. The bandwidth acquired with Wayport offloads the AT&T network relatively cheaply. AT&T’s enthusiasm for Wi-Fi is such that it is selling some new Wi-Fi phones without requiring a data subscription.

The enterprise market is one that mobile network operators have long neglected. It is small relative to the consumer market, and harder to fit into a one-size-fits-all model. Even so, in these times of scraping for revenue in every corner, and with the steady rise of the Blackberry, the network operators are taking a serious look at the enterprise market.

The device manufacturers are way ahead of the network operators on this issue: the iPhone now comes with a lot of enterprise readiness Kool-Aid; Windows Mobile makes manageability representations, as does Nokia with its Eseries handsets. RIM, the current king of the enterprise smartphone vendors also pitches its IT-friendliness.

Wi-Fi in smartphones has benefits and drawbacks for enterprises. One benefit is that you have another smart device on the corporate LAN to enhance productivity. A drawback is that you have another smart device on the corporate LAN ripe for viruses and other security breaches. But that issue is mitigated to some extent if smartphones don’t have Wi-Fi. So it’s arguable that the Storm may be more enterprise-friendly as a result of its lack of Wi-Fi. Again, if the Storm becomes a hit in enterprises that argument will turn out to hold water. If the Storm is a flop for other reasons, we still won’t know, and it will have failed as a trial balloon for Wi-Fi-less enterprise smartphones.

Low cost international calls from your mobile phone

Thursday, November 6th, 2008

I wrote about the vast array of ways to bypass international tolls in my Internet Telephony column a while back. Now there is an interesting web site, LowCostMob.com, that gives a listing of the services available and technical explanations of how they work.

If you go to the “contact us” link on the website you can type in “user feedback” with mini-reviews of the services. I presume that over time the database of user comments will become an additional helpful resource on the site.

All these services work to make calls to international destinations cheaper, but if you actually travel abroad you still have to pay exorbitant roaming charges for using the cellular network. The benefit of dual-mode (Wi-Fi plus cellular) phones is that with some of them you can use the Wi-Fi connection to make VoIP calls and completely bypass the cellular network, avoiding international roaming charges. Not all the listed services support this feature, and not all dual mode phones do either.
