There is no Free Wi-Fi, but there can be Sustainable Wi-Fi

Free Wi-Fi Zone


Today Engadget reported that Free WiFi provider admits to making up 90 percent of its revenues. The company, Gowex, runs networks in 85 cities around the world (according to company WWW pages) offices in Madrid, Paris, London, Buenos Aires and Shanghai. The company claimed that it had developed a sustainable business model for free Wi-Fi based on the idea that company makes its revenues from partnerships with local governments, carriers with Wi-Fi offloading and from premium fees (i.e. selling premium user accounts).

Some may view this as a proof that Gowex's business idea and model did not work, but I would not claim that without looking into if they managed to get any revenues at all. Running company badly and falsifying revenues and accounting are very different things from the actual business idea and model not working.  I actually think that those ideas from where Gowex planned to get revenues are valid ones and they seem to have made real roaming deals with roaming brokers such as iPass, Boingo etc. These revenues could then be used to subsidise the service costs of running WiFi networks or related services, but naturally the company should get more revenues from the service it provides than the costs of producing it. And that is actually why I do not believe Free Wi-Fi exists.

The Free Wi-Fi is an illusion for consumers. Somebody always ends up with the bill. It may be the company, organisation or city providing or buying the Free Wi-Fi service out of hospitability. It may be an airport or a shopping mall deploying or buying a service for tracking customer movements or web surfing, but like many other free Internet services, Free Wi-Fi is not really free. You as a consumer may think that with Free Wi-Fi that you are still customer, but the reality is that the one providing and paying for Free Wi-Fi service, needs to get enough benefits and/or revenue from providing the free service to you and their benefit maybe the data about you.

Where Gowex was on a right is that providing Wi-Fi for free needs to be sustainable. The Wi-Fi network service needs to provide so much benefits for the one paying for it, that the payer is willing to cover the costs of running, maintaining and developing the network. Too often in many hospitability guest networks (hotel/conference Wi-Fi, company guest Wi-Fi) the deployed network may serve its users when it was first deployed, but the development of it (Internet bandwidth capacity, better radios) is neglected until enough users are complaining about it. In city-wide Wi-Fi networks similar kind of problems occur, when city-wide Wi-Fi is setup with development project money from government or EU without any plan how to cover the costs after the development project has ended.

Sustainable Wi-Fi networks should be planned so that they can be maintained and even developed with the revenues coming from organisations and companies benefitting from the network service, or from something measurable the network provides. There even exists a successful example of this kind of sustainable global Wi-Fi network concept -- eduroam (*).



In eduroam, universities, research institutions, government organisations and even cities have seen the benefits of joining their existing Wi-Fi networks via federated RADIUS authentication and providing this way a free Wi-Fi around the world for researchers, teachers and students. Every organisation deploys, maintains and develops their own network service with their own funding and shares it with the other eduroam organisations. There is no single vendor, service provider or organisation controlling anything. Instead, every vendor, service provider or organisation which is ready to fulfil the open requirements and standard interfaces is welcome to join or provide equipment or services to other eduroam organisations. There are not a lot of revenues or profits moved around, just normal network and authentication business for companies, but the benefits are clear for participants to justify the costs of basically running the Wi-Fi networks, which they are going to do anyway.

eduroam is real, sustainable Wi-Fi and I am hoping that we (Arch Red and Open System Consultants) may help in bringing its benefits also to wider audience in a very near future. eduroam itself still limits its use to universities and research organisations and networks and cannot unfortunately yet be used as a common global concept to provide sustainable Wi-Fi for all.

What about CAs in mobile devices?

The Diginotar case encouraged finally most operating system and browser vendors to remove the DigiNotar CA from their trusted CAs. In case you are not familiar with the case, I suggest you check the following links where the case has been analysed more carefully:

In addition to the analyses you may also want to see a Black Hat 2011 presentation from: An executive summary of the would be:
One of the generally trusted certificate authorities (DigiNotar) failed to protect its services and was compromised. There now exists DigiNotar signed certificates in the wild free for attackers to use for several online and software update services including companies such as Microsoft, Google and organisations like Mozilla(Firefox). This means that if your operating system or browser certificate stores are not updated, your device is vulnerable to attacks based on these certificates. Attacks can for example install malware on your computer in the form of updates or collect your passwords for various services.
But since most of the operating system and browser vendors already reacted and I have installed updates I am now secure, right?
No you are not. While most of the operating system and browser have removed the CA certificate in question we still have a huge number of devices which may have those CA certificates installed -- the mobile devices. I have not yet received an update for my Android phone (Samsung Google Nexus S) and I think it is pretty much the same for all other mobile phone vendors too, Windows Phones, old and new S40, Symbian, Maemo phones and iPhones included. And it does not even stop to mobile phones, nowadays we have already tablets and all kinds of embedded devices, which may have the operating system included certs installed. Our mobile devices continue to be vulnerable to those leaked certificates and in most cases the users cannot even check or do anything to remove the certificates!
One glimmer of hope is that DigiNotar has not perhaps been in all mobile devices' CA certificate storage, but then again we still have Comodo there and now GlobalSign has stopped signing certificates and is checking their systems for intrusion. Another glimmer of hope is that maybe perhaps now industry will take a closer look at the current certificate authority structure and the system will be improved or fixed for example like Moxie Marlinspike suggests.

Microsoft recommends _not_ to disable IPv6

In IPv6 seminars you often hear the claim that Microsoft recommends not to disable IPv6. The source for this recommendation is not often presented, but now I did look it up for further reference and discussion with IT departments, which disable IPv6 from their computers.


The Argument against Disabling IPv6

It is unfortunate that some organizations disable IPv6 on their computers running Windows Vista or Windows Server 2008, where it is installed and enabled by default. Many disable IPv6-based on the assumption that they are not running any applications or services that use it. Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. This is not true.

From Microsoft's perspective, IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6. If IPv6 is disabled on Windows Vista, Windows Server 2008, or later versions, some components will not function. Moreover, applications that you might not think are using IPv6—such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail—could be.

Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. By leaving IPv6 enabled, you do not disable IPv6-only applications and services (for example, HomeGroup in Windows 7 and DirectAccess in Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can take advantage of IPv6-enhanced connectivity.

Cloud Computing Business Models

As a part of my postgraduate studies I attended a TUT seminar course about cloud computing and chose to do my presentation about the cloud computing business models. Obviously this only covers only small part of them, but the presentation gives a general idea about what models are available and on what level of cloud computing solutions (IaaS, PaaS, SaaS etc.).


Feel free to comment or ask questions about the presentation and I will try to answer them in the comments.
