Going to Boston

Looks like I’ll be in Boston at the beginning of June for a couple of days. As I haven’t been at the east coast before please let me know if you have any suggestions for things to see in and around Boston, wireless, technology and historical. My schedule is packed with interesting and exciting stuff but I am sure I’ll find the time for a bit of sightseeing as well. If you live near by and would like to meet, please let me know as well. My eMail address is "gsmumts AT gmx.de".

The Carnival Of The Mobilists #74

Wow, a year has passed since I last had the honor to host the Carnival of the Mobilists on my site. Last time I got the heads up for hosting the Carnival via eMail while sitting in a taxi on the way from Lisbon airport to the city center. This time around, Rome’s the place, and my notebook is wirelessly connected via HSDPA.

It has been a great time since then in many ways and people contributing to the Carnival have sparked many great thoughts and ideas in me. The Carnival has also been invaluable to me in finding new people entering the mobile space and helped me a lot to keep my blog roll fine tuned to my interests and the ever growing, sometimes shrinking, but greatly evolving blog sites on mobile out there on the web. So thanks to all of you contributing to the Carnival and I hope you enjoy this week’s selection again:

  • Nokia’s Transition To An Internet / Computer Company: Not to miss, and thus my favorite post of the week, is Michael Mace‘s analysis at Mobile Opportunity of Nokia’s transition process which top managers of the company keep mentioning to the press.
  • Open Motorola: A lot of articles in this and previous Carnivals on Nokia so I was delighted to see Jason Devitt of Skydeck submitting an article about open OS platforms being pushed by Motorola.
    He doesn’t only discuss platform strategy for the 2007 Motorola device
    collection but also what OEMs are doing to get a presence in the
    wireless market.
  • Innovate Europe 07: Rudy de Waele of m-trends.org must have had an exhilarating and busy week at Innovate Europe 07 as it seems he aimed for the Guinness Book of Records with the length of his blog post. His post contains tons of interesting information and is well structured so you’ll find the pieces of information that interest you very quickly.
  • MobileCampNYC: More meeting and conference reporting: Marshall Sponder of SmartMobs has posted his impressions of MobileCampNYC which took place this week. Too bad New York is so far away from here, looks like it was worth going.
  • Web 2.0 Micro Payment: Mobile Web 2.0 evangelist Ajit Jaokar writes about content discovery on YouTube and about finding a song/video so dear to him that he had to keep listening/viewing all afternoon. Dreaming aside he starts thinking about how producer, artist and distributer could be paid for their effort and his pleasure. Check it out at his Open Gardens blog.
  • Hardware/Software Bugs: The functionality of mobile phones
    keeps growing and growing which is both good and bad. The down side is
    of course that the more stuff is inside the more can break. Tarek El Ghazali from "Symbiano-Tek" reports some trouble with his N80 that keeps forgetting time and date.
  • Warranty Service For That Mobile Computer: Ricky Cadden of "Symbian-Guru.com" writes about his bad experiences with the NokiaUSA warranty service.
    I have to agree with him, 24 days return time for a broken N-series
    mobile is not acceptable. Nokia claims their n-series devices
    replace computer, camera, maps, etc. etc. That’s nice but it also
    creates a single point of failure that needs to be fixed ASAP an not in
    24 days…
  • The World Before And After The iPod: I very much like Tomi Ahonen‘s thoughts about mobile on his "Communities Dominate Brands" site. This week he features an exciting article in which he postulates that soon mobile history will be seen as a time before the iPhone and a time after the iPhone. An article not to be missed.
  • The Mobile But Non Web Device: In contrast to the article before, Barry Welford over at "Stay Go Links" argues that the mobile web is only a thing for geeks and companies should rather concentrate on developing a keyless phone just for making phone calls and not much else. He must feel a bit lonely with his opinion among the other articles in the Carnival this week. Nevertheless, his blog entry contains some interesting points!
  • JavaFX: Sun seems to have decided to enter the mobile phone OS market. Competition is good and David Beers over at "Software Everywhere" takes a critical look at JavaFX, a mix of Linux and Java.
  • U.S. Wireless Data Revenues: Chetan Sharma reports the latest numbers from wireless operators (sorry, wireless carriers) in the U.S. on "Always On Real-Time". 5 billion dollars revenue from mobile data services in the last quarter, 60% of it from non-SMS revenue. Here are the details.
  • Where To Store The Data: Mark Wickersham sent in a post for Barbara Ballard of "Little Springs Design" with an introduction of where to developers should store their data. "local, server, and mixed mode applications" is the title of the post.

Wow, what a selection again this week, I hope you enjoyed it! We are almost at the end of the post and I have changed location in the meantime from Rome to Paris. Next week, Andreas Constantinou of the VisionMobile Forum will host the carnival.

And last but not least, if you want to submit a story of your own, send an eMail by next Friday to "mobilists at gmail.com" or use the carnival form here.

The Nokia N73 Is A Rising Star

Wherever I go these days I see people with Nokia N-73 phones walking around. Incredible for a phone that has just been available for a couple of months. I think there are even more people now with an N-73 than with an N-70 which I think has been announced by Nokia as their so far most successful smartphone. Take a look at the Flickr statistics for picture uploads from Nokia phones. The curve for the N-73 shoots up like a rocket and has surpassed all Nokia’s by far already. A comparison of picture uploads between different brands would be interesting. Anyone aware of such a statistic?

Wind Italy seems to soft launch HSDPA

Quite a surprise today in Rome when my data card suddenly showed HSDPA instead of 3G when I logged on to the Internet with a SIM card from WIND. I haven’t seen an announcement on their web page yet nor anywhere in the streets. So I checked Google news, but came up empty handed as well. Did anyone besides me notice as well?

The transmission speed, however, was far from what it could be (like for example in the TIM network, for measurement details see here) due to constant TCP retries which I’ve also experienced in 3G mode in the past. It doesn’t have a lot of impact on web browsing and Skype but downloads of larger files take 2-3 times longer than over a good connection. I tried with a second HSDPA terminal of a different manufacturer and got the same results. Let’s hope Wind fixes this issue before the official launch.

Cool N95 Marketing

The Nokia N95’s had me in it’s ban every since it was first announced. Finally, it’s also making it into the shops. I especially liked what I saw today when I walked by a shopping window of a mobile store in Rome. Take a close look at the trash bin on the left of the second picture 🙂

When I saw the first N95 in a store a couple of weeks ago the price was a hefty €739.-. Last week I saw one with a price tag of €699.-. And this week I saw it for €649.- (taxes included), no SIM lock. Very nice, I hope it keeps going in this direction. Amazon.de ships it (to Germany and Austria) for €663.95, postage and packing included.

Italy, Mobile-TV and Football

DVB-H has been introduced in Italy already last year and it looks like it’s catching on. Now offered by Three and TIM, Italy not only seems to be the land where you can see people making video calls, it also seems to be the land of people that are watching TV on the go. It might have something to do with football as both people I observed, one on Saturday and one today, where watching a football game. While one of them was a hotel employee using his break outside to peek at a game, the other might have been an office worker waiting at the bus stop in Rome. People watching mobile TV are unmistakable because the mobile TV phones currently offered in Italy are mostly by Samsung, have a screen that can be rotated by 90 degrees and have a nice little extractable DVB-H antenna. Hm, maybe I should give it a try while I am here…

The Carnival of the Mobilists 73 at Xen’s blog

Cotmbutton
I am a bit late to the Carnival of the Mobilists this week, probably because of some violent stomach problems and night shifts to get some equipment running in a wireless network in Italy. Anyway, here’s the link to this week’s edition of the Carnival of the Mobilists, this time hosted by Xen Mendelsohn. Great job I very much enjoyed reading it and many of the articles you point to. Next week, I’ll have the honor of hosting the Carnival, so stay tuned here!

The Timing Advance Is Back with LTE and WiMAX

In the high times of GSM, mobile enthusiasts equipped with mobile phones with an engineering menu had a lot of fun finding base stations by taking a closer look at the timing advance parameter. This parameter implicitly contains the distance to the base station the mobile currently communicates with. A GSM mobile requires this parameter as it has to start sending data in it’s timeslot earlier the farther it is away from the base station. This is necessary as radio waves only travel at the speed of light. If no adjustment is made, transmissions of a far away mobile tramples over transmissions in the next time slot of another mobile as they would arrive too late.

With UMTS things got a bit difficult as due to the CDMA approach of the radio interface a timing advance parameter was not necessary anymore. Unfortunately this makes finding specific UMTS base stations quite difficult. But don’t despair, LTE and WiMAX will require a timing advance parameter again since these systems are based on OFDMA and timeslots. This means that the network has to send timing advance information to the mobiles again to ensure their data always arrives at the instant it is supposed to. So network tracking should get easier again in the future!

Orange France Promo For UMA – Do You Get It?

03052007808
Here’s a picture of an Orange France advertisement for their UMA service called "Unik" for which they now also offer a Nokia 6086. I like advertisement that is clear, easy to understand, that makes me want something and that gives me all the facts. But this one!? It tells people nothing… How should people know that this panel promotes a fixed/mobile convergence product and that you need a France Telecom DSL connection and Wifi access point to use it? Why should people want to buy this phone after seeing the pannel? There are so many other 1 Euro (with a * to the fine print) ads out there. I am really puzzled. Maybe my French readers can enlighten me?

802.16j: WiMAX For WiMAX Backhaul

One of the main OPEX (operational expenditure) drivers in mobile networks today is the requirement to connect each base station directly to the network. In most cases this means installing a cable or microwave connection at each base station site. For fixed line connections, UMTS/HSPA base stations mostly use a number of E-1 or T-1 links today, each being capable of transmitting about 2 MBits/s. With rising bandwidths, however, using several E-1 links for each base station will soon become difficult for both cost and availability of wires. Alternatives are fiber or using a transmission technology which can get more out of a pair of copper cables. Nevertheless, it will remain expensive.

For WiMAX networks, the IEEE has started in 2006 to work on 802.16j "Mobile Multihop Relay" (MMR). The basic idea behind MMR is to allow WiMAX base stations which do not have a backhaul connection to communicate with base stations that do. On the one hand this will of course reduce the bandwidth  available to users in the cells involved in relaying packets. On the other hand it’s an elegant way to save costs and extend network coverage into areas where connecting a base station directly to the network via a fixed line connection is economically or technically not feasible.
