About The Open Gardens Blog

I (Ajit) founded the blog on May 26, 2005 based on my vision and philosophy of OpenGardens i.e. the philosophical opposite of 'walled gardens' especially as applicable to the mobile data industry.

Today, the OpenGardens blog is one of the few blogs that span both the Web and the Mobile domains.

The blog covers wireless/mobile applications, open networks and mobile web 2.0. My vision behind the OpenGardens blog has been :

  • The blog is about the Mobile data industry and Digital convergence('Mobile web 2.0')
  • Analysis is more important than story/controversy. I don't believe that bloggers are true journalists. The blog is not about the latest 'story' but it's more about independent analysis/viewpoint
  • The OpenGardens blog is broadly about opening up the networks, growing digital usage and digital businesses i.e. we don't advocate closed networks, broadcast media etc
  • It is about disruptive digital technologies

Founder and Chief blogger : Ajit Jaokar

Ajit Jaokar is the founder of the London based publishing and research company futuretext (www.futuretext.com) focussed on emerging Web and Mobile technologies -including Web 2.0 and Mobile Web 2.0.

His thinking is widely followed in the industry and his blog, the OpenGardensBlog (www.opengardensblog.futuretext.com), which was recently rated a top 20 wireless blog worldwide

In 2009-2010, Ajit was nominated as part of the Global Agenda Council on the Future of the Internet by the world economic forum. He hopes to use this opportunity to further extend the pragmatic viewpoint of the evolution of Telecoms networks in an open ecosystem.

(Note: The Network of Global Agenda Councils plays a significant role in shaping the global agenda by monitoring global issues and elaborating recommendations to address them. Each Council, comprised of 15-20 Members, serves as an advisory board to the Forum and other interested parties, such as governments and international organizations. The Global Agenda Councils also act as the intellectual drivers of the World Economic Forum's Global Redesign Initiative, an unprecedented international, multistakeholder and multimedia dialogue that aims to develop a 21st-century vision of global cooperation. Members of the G20, the UN and other International Organizations have pledged their support for this initiative. )

Ajit is best known for his books Mobile Web 2.0, Social Media Marketing. Two new books ('Open Mobile' and 'Implementing Mobile Web 2.0') are being released in 2009.

His consulting activities include working with companies to define value propositions across the device, network, Web and Social networking stack spanning both technology and strategy. He has worked with a range of commercial and government organizations globally including The European Union, Telecoms Operators, Device manufacturers, social networking companies and security companies in various strategic and visionary roles

His recent talks and forthcoming talks include: CEBIT 2009;MobileWorld Congress(2007, 2008, 2009); Keynote at O Reilly Web20 expo (April 2007);Keynote at Java One; European Parliament – Brussels – (Electronic Internet Foundation); Stanford University's Digital visions program;MIT Sloan;Fraunhofer FOKUS ; University of St. Gallen (Switzerland); Mobile Web Strategies (partner event of CTIA in San Francisco)

No SIP/IMS stack for Android?

I spent a great two days at the Fraunhofer FOKUS IMS 2007 IMS workshop. My company (futuretext) is a partner of Fraunhofer FOKUS – so I am a part of the FOKUS family as Dr Thomas Magedanz (Director of Fraunhofer FOKUS) calls it.

It’s rare to see so many people, very high level of participation and also great Operator participation at events nowadays – and this event had all three ..

Hence, Fraunhofer FOKUS IMS 2007 IMS workshop was one of the best events I attended this year. Very much recommended! .

I was a part of the workshop on Mobile Web 2.0 and IMS(along with Dr Thomas Magedanz and Niklas Blum – Deputy Director of Fraunhofer FOKUS)

Here is an example why I loved this event .. It’s the quality of the discussion ..

One of the questions I asked was: Android has no SIP stack. It also has no IMS stack/interface to speak of either. What are the implications of that?

This is interesting .. It may be a gap for a start-up. Or .. It may be irrelevant – here is why ..

Basically IMS is a secure mobile connection and / or a guaranteed (QOS) mobile connection. By working at the service layer, Google overcomes some of the issues that hamper IMS type applications. In doing so, it foregoes certain applications(potentially things requiring some form of higher QOS.).

However, if the bearer is WiFi(as it is starting to be increasingly) then this does not matter because many network /telephony applications can be run over WiFi. Downside is low QOS.

In any case, the lack of IMS/SIP support is interesting and one to watch

I will have many more blogs on this event since there was a lot to learn and I am still getting to grips with it all ..

Among the people who contributed to the above discussion were Malcolm Wardlaw – Director converged services – BT group, Roberta Minerva – Long term research TIM, Thomas, Niklas and many more

And the evening social event was great .. Pasta Opera is a unique event! Even for one who has no understanding of classical music

  1. Indeed, with new operating system(s) emerging, operators should really think about what role they want to play in the (web) services domain and provide interesting enablers to the applications community that are already linked to the operating systems for better performance etc.

  2. Fraunhofer Institut is hardly the place to go to if you want a neutral view on this (they having funding from companies who promote IMS). IMS is not needed to get a secure connection. It is sad to think that IMS gives you QoS (no matter what hardcore telco vendors tell you) i.e. QoS or lack of it are determined in the transport layer: IMS’s role here is mostly superficial and mostly it is to do with call admission … which can be achieved in other ways. I am not saying that IMS does not have a role to play …. especially if want to spend a lot of money for little return.

  3. I expect to be in a position to say more (in my blog) later in December, but for now let me point out this quote, in the Open Handset Alliance press release here:
    http://www.openhandsetalliance.com/press_110507.html
    “NMS Communications is pleased to add our industry-leading IMS framework to the Open Handset Alliance initiative. I believe this Alliance will unlock unprecedented innovation in mobile operating systems benefiting operators, consumers and suppliers alike.”
    – Joel Hughes, General Manager, Mobile Applications, NMS Communications

  4. Hey, Worked on making a simple SIP User Agent for Android. It is based on the mjsip User Agent and the mjsip stack ported for Android by http://www.hsc.com

  5. As a reply to the post from November, 29th by anonymous: Only because we do projects with big telco vendors that promote their products and also IMS, it does not mean that as an independent research institute, we don’t take our freedom of an independent opinion. This is actually what is always wanted by our partners and customers. But indeed, there is a lot to argue about IMS, and I believe only the future will show us which party in this discussion succeeds.
