Myth of Wi-Fi access for your iPhone

July 18, 2012 1 comment

Since I downloaded speedtest.net app for my iPhone, I turned into a “speed test” junky! This afternoon, while I was in a Starbucks, I did two measurements; one through my Wi-Fi connection (which was already switched to thanks to ATT) and one through my cellular connection. While with my cellular connection I got constantly +4 Mbps in downlink and +2.5 Mbps in uplink direction, my Wi-Fi measurements constantly show 1.3 Mbps in both directions. I guess they use a T1 to connect their store to the Internet. While for customers with limited data plans switching to Wi-Fi will reduce their bill, the myth that “switching to Wi-Fi will provide higher bitrates” is not valid anymore. Years ago, with GPRS/EDGE and bad data coverage areas, this argument was right, but not anymore. The idea that let the iPhone decides to switch between Wi-Fi and cellular just because it can save some money or release the valuable cellular resources for operator is true, but it does not mean the subscribers will have a better experience. Switching to public Wi-Fi hot spots will limit your performance; there should be an end-to-end QoS measurement mechanism to make this decision. Either it is a part of SON or Release 12 of 3GPP, I don’t know. But it is a must and should be out soon.

Win the Competition Like Apple Does

October 5, 2011 Leave a comment

The fanfare for new iPhone launch is behind us. The only surprise was the new uniform for Apple CEO is changed from a black sweater to a black shirt; still it is a black top though!

For me, the most interesting part of Cook’s presentation was the announcement that iPhone has 5% of mobile market share worldwide. What I like about it is the sense of rebellion Apple brings to legacy market assumptions as usual. When Apple launched iPhone in 2007, there were lots of top investors who called this move stupid. They called Steve Jobs a “bigoted selfish individual” (if he was a female probably they would called her Ayn Rand resurrections) who is going against all business common sense and tries to enter a very mature market, with well established players and low margins. Steve Jobs proved that even if you are “the last” to enter a market, you can win if you produce “the best” with “highest margins” and still beats everyone. Even a lazy giant like Nokia!

My Mobile Data Usage!

July 3, 2011 5 comments

iPad and iPhone do 60% of US mobile browsing and 8.2% of US web browsing is from mobile devices. These are pretty high percentages compare to five years ago. Then I looked at my mobile phone bills and statistics and I found out why. I was a Blackberry user since 2000; virtually hooks to it. This January I decided to switch to iPhone and rest is history! This is from my ATT monthly bill. I am glad I have an unlimited data plan; I am not sure about ATT though 🙂

Verizon Wireless iPhone; Challenges its Data Network and Android

November 6, 2010 Leave a comment

This month Fortune cover shows an iPhone and referring to launch of Verizon iPhone as “get ready for the dream phone”. People familiar with the case speculate Verizon will launch iPhone in early 2011. Lots of US mobile phone users were praying for this news for years. As the largest US mobile operator; by number of subscriber, Verizon was always preferred choice for consumers as the ‘more reliable” service provider. Its CDMA based 2G network, better coverage and call quality in general in the first part of this decade made it preferred choice for voice users.

For the past couple of years, smartphones start to challenge data network capacity. While early 2000 was the hype of wireless data networks deployment, there was no real data traffic until couple of years ago. Operator’s huge investment on mobile data upgrade was sitting idle for years before iPhone shows the art of smartphone development to other vendors and flooding the market with its clones. ATT launch of iPhone in 2007 was smooth until the huge amount of data traffic starts to cripple its network in dense markets, including New York and San Francisco. ATT executives claims the dream of a better iPhone experience on Verizon network will shattered as soon as operator stats to sell and distribute iPhone across its networks. Although Driod and other Andriod based phones were very popular, their popularity and traffic load would not be even close to after iPhone launch. This points to another question; if Verizon starts to sell iPhone, does Andriod based phones continue to growth (at least in the US)? Lots of Verizon geeky data users were forced to buy Android phones because they didn’t have other choices. By introducing iPhone, Verizon introduces a real competitor for its Andriod phones.

Nokia CEO Will Step Down; What a Waste of Four Years

September 10, 2010 Leave a comment

It happened much sooner than I thought. “Nokia Corp. said it was replacing embattled Chief Executive Olli-Pekka Kallasvuo with Microsoft Corp.’s Stephen Elop, as the world’s largest handset maker seeks to reverse steep declines in earnings and market share that have decimated its share price”. After four years of constant struggle and lack of a clear strategy toward future products and particularly high-end mobile phones (smartphones) Mr Kallasvuo kicked out of the door. It was a well know fact that Nokia is heading south, but the speed of it was really surprising for everyone. Many analysts feel that Nokia was caught flat-footed by the iPhone’s success and blame its weakness in smartphones for shaving about 70% off of Nokia’s market value; or more than $90 billion, over the past three years. Basically, Nokia morphed into a “giant dwarf”; a huge player but not a huge force to shape the industry; a follower and not a leader. And it was not all about market share; the overall management of the company was a shenanigan! Former employees describe the structure of the company as a confusing matrix organization, akin to the “Soviet Union.” While Nokia was ahead on hot trends in the tech industry such as internet services and 3-D, lengthy approval processes and a lack of leadership inside of Nokia bogged down these innovations. One former employee added that Nokia, given its size, was never eager to invest in innovations that didn’t have a high volume potential across many of Nokia’s markets. Even the timing of the announcement is awkward and shows a little bit of rush and chaos within the organization. Next week, the company holds its annual “Nokia World” conference in London, where Mr. Kallasvuo was expected to articulate a new strategy to regain its footing in the industry and to present a new smartphone, the N8. The switch at the top of the company will likely draw attention away from those issues. But how this change is going to affect Nokia as a company? First of all Mr Elop is not Finish; he is not even European. “Nokia is definitely a Finnish company. It was born from Finnish culture,” says Juhani Risku, 53, a former Nokia executive, who also wrote a book about the company. He is Canadian at least and not American, so he can be a little bit less brutal. But in any case, this is going to be a dramatic cultural shift for Nokia. Northern American management style is definitely more aggressive and non-European. Secondly, the momentum is already shifted toward Apple, Google and HTC as the leaders of smartphone market. And finally he comes from Microsoft; well they have their own struggles in mobile market for the past couple of years. It will be tough to change it in short term. How Mr Elop is going to tackle these issues and change the direction of the company are questions that will be answered in the next couple of months, if not years.

Another day and another question about Clearwire future!

September 2, 2010 Leave a comment

Here we go again; another day and another question about Clearwire future! They need money again and so far Sprint was the only main source of cash, but probably not for long. Sprint, which merged its wireless broadband unit with Clearwire in 2008, invested $1.2 billion into the company in late 2009. Credit Suisse analyst Jonathan Chaplin estimates Clearwire needs $4 billion to cover 200 million people in the U.S. by the end of 2011, up from the 120 million people it expects to cover by the end of this year. With limitations in the capital market, there are not many choices for Clearwire. While Sprint board is already divided on the issue of future capital injection, some people speculating the need to bring another operator as a major investor; like T-Mobile USA, into the mix to inject some capital and reduce the pressure on Sprint. The logic is sharing the network with Sprint could cut the cost for both parties, T-Mobile can benefit from this collaboration since they do not have a clear plan for their 4G roll-out.

But it is not that simple. T-Mobile as a GSM/UMTS based operator and in line with other T-Mobile operations around the world, needs to follow LTE path for the sake of its own integrity. While Sprint is struggling with its WiMAX launch because of limited available handsets, this issue will be even more problematic for T-Mobile, since most of the GSM world players have already chosen LTE as their migration path. Therefore, there will be no or very limited market for a GSM/UMTS/WiMAX phone.

Bottom line, it is decision time for Clearwire. They should come out of cash burning mode and create a real revenue to survive in this market.

Nokia; General Motors of Mobile Industry

August 15, 2010 Leave a comment

Olli-Pekka Kallasvuo took over the world’s largest mobile phone manufacturer in the summer of 2006. Six months later Steve Jobs unveiled the iPhone, and it has been downhill ever since. Nokia’s shares have tumbled by nearly two-thirds. Its profit margins have withered from 15% to 7%. And the firm has all but imploded in America, despite Mr Kallasvuo’s pledge to conquer the region. Since 2005, experts in mobile industry started to predict a very gloomy future for the dying giant. While they stick to their legacy phones and are happy with major penetration in the developing countries; read it as high volume low margin domains, other competitors started to target higher margin products including smatphones. Developing countries will be all using smartphones within the next five years anyway.

Although people think Nokia’s most obvious problem is being squeezed out of the smartphone market, its biggest mistake was lack of vision for much higher margin products that come with them; applications! Smartphones are not only lucrative in themselves; they are the gateway to the even juicier market for services and “apps”. Apple’s iPhone and Google’s Android range compete on “cool”. BlackBerry is synonymous with business. But what does Nokia stand for? As usual Nokia still chases the pack. Mr Kallasvuo argues that the forthcoming N8—an all-singing-and-dancing handset that is due to hit the stores in October after several delays—will “mark the beginning of our renewal”; I guess this the fifth or sixth time they are waiting for such a product in the past five years. But previews suggest that the phone is more about catching up than setting the pace. Nokia’s ads tout its “revolutionary” touch-screen technology, built-in camera and GPS. Yet such baubles are already commonplace. It is time for Nokia board to wake up and consider a new direction. GM was once dominating car industry, but lack of innovation forced them to bankruptcy. Nokia should learn its lessons; things are changed!
