Over the past several months I have written three posts about WiFi’s ever-increasing role as a complement to the wireless carriers:

• WiFi: The Real Threat to the Mobile Carriers
• Is WiFi Becoming the Unregulated Stealth Carrier of the Future?
• Traveling in a Bipolar Mobile Mode

Basically, in my recent travels I have found that WiFi access is becoming more readily available at home, in the office and, as I travel, in hotels, airports and restaurants. Especially when in countries where roaming charges can be excessive, I seek out WiFi access points when on my BlackBerry and iPhone to minimize roaming expense for data.

Now that Apple is allowing VoIP over 3G, this strategy will become even more critical when using the Skype and Truphone applications for the  iPhone where the conversation uses VoIP technology over the data channel. While my home network data plan has sufficient monthly capacity for making these calls from within Canada, I’m not sure I want to be paying $1/MB when roaming in, say, the U.S. for a Skype call.

Brough Turner has built up an immense wealth of knowledge about Internet infrastructure and wireless carriers, not only from the technology perspective but also the business implications, including costs. He has recently published a post, WiFi Offload, not Femtocells, where, while postulating that Femtocell technology is too complex and costly become mainstream, he supports his argument by pointing out the business reasons for relying on WiFi as a primary “carrier” for wireless:

• “most mobile data is destined for the open Internet, not for someplace on the mobile operator’s network” Apparently 96% to 99%. Yet, relative to a direct broadband Internet connection, it’s much more costly per user (and more complex) for a wireless carrier to provide the tower and backhaul infrastructure required to connect a mobile phone to the Internet.
• “the primary sources of mobile data demand are laptops, notebooks and smart phones”. It’s become reality that most mobile devices these days support WiFi in addition to 3G/LTE/4G. And the iPad is a “data only” device. Demand for wireless connections will continue to grow rapidly; carriers need to look at the cost of new towers vs encouraging installation of WiFi access points (for which they have zero cost if the subscriber installs the access point).
• “WiFi access points cost less than femtocells” When end users can set up a WiFi access point for around $100 whereas the carriers’ towers can run $1MM to $2MM per tower and require a backhaul Internet link, it is actually to the carrier’s capital cost advantage to support the build out of WiFi access points, whether private (home, office) or public (hotels, restaurants, airports, etc.).
• “WiFi access points are showing up everywhere”. Yep, see the posts referenced above.

Three instances where WiFi has “bailed me out” recently:

• On both my January trips to CES and IT Expo, I had set up voice roaming with Rogers. Just one complication – over 80% of the calls I received, via roaming partner AT&T, had such poor call quality I had to ask the party to hang up and call them back. But when I called them back it was using Skype for iPhone over WiFi connections to have a more than acceptable call quality. AT&T simply failed, big time.
• At one recent hotel the hotel wanted to charge $14.95 per day per PC or smartphone for a WiFi connection. However, the hotel chain involved also had an arrangement with Boingo. Once I got the Boingo availability reminder I simply upgraded my mobile Boingo plan to a combined plan at $17.95 per month, connected my laptop, BlackBerry and iPhone and bypassed the hotel charges. As a bonus, I was also able to use the plan while waiting for my flights at two airports, amongst other Boingo-supported locations.
• During my trips to Spain last fall I ended up in situations where no public carrier access was available but there was WiFi access – once in an office with no 3G signal and once in a hotel in an ancient building with WiFi but no landline phone. Once again in these situations WiFi was the path to get data and Skype for iPhone or Truphone was used for voice calls.

The Bottom Line: Brough says it best in answering his own question “What should an operator do?”:

Mobile operators need to focus on providing bundles of connectivity, not on whether its 3G/4G or Wi-Fi. They should be encouraging Wi-Fi offload by bundling “free” public Wi-Fi access with their mobile data plans.

In the long term, it’s likely most mobile data bytes will go over Wi-Fi.  The 3G/4G network is still necessary to provide a backup path when no Wi-Fi is available. Mobile operators who recognize this can still come out on top, if they focus on facilitating connectivity for their customers regardless of the technology involved.

Note to Rogers: while Andy makes great use of UMA from T-Mobile’s @Home service during his overseas travels, Canadians would appreciate the same level of support for Rogers’ UMA-based services, which are currently limited to access from WiFi hotspots within Canada.

During my three plus years of blogging, the most educational and informative conference for keeping up with innovation in the “Emerging Communications” space has been eComm, the Emerging Communications Conference (and now Awards). And now eComm is coming to Europe in two weeks.

Conference organizer Lee Dryburgh and his team of advisors have assembled many of the top thinkers and activists in the IP-based communications space with the goal to “promote and accelerate communications innovation”. On the website’s home page is an outline of the forthcoming changes foreseen:

Telecom is becoming software

Today’s model of the telephony and SMS cash-cows will significantly dry up long-term

“Phones” are becoming general purpose always-on computers

A march is underway to change how spectrum is allocated and utilised

Applications innovation is being democratised

The media industry is converging with personal communications

Internet-style ecosystems are starting to pressurise the traditional value chain

Search engines and computer manufactures are encroaching into the space

App downloads; media content and even communication streams are increasingly routing-around operator’s billing systems

The telecom kingdom is fragmenting daily.

It’s only at eComm that you will find respected experts such as Martin Geddes, Thomas Howe, Alan Duric, Brough Turner, Dean Bubley, James Enck, Jonathan Christensen, Jan Linden and Gerd Leonhard all under one roof at the same time. But amongst the others, there’s always at least one or two who will surprise us and challenge our thinking about how the telecommunications industry will evolve. While we all talk about “networking” from a technology perspective, the personal networking at eComm is just as valuable as the presentations.

Also this week it was announced that Skype has taken on the role of Headline Sponsor of the show while innovative companies such as Voxbone, Voxeo, GIPS and Voice Sage are Platinum Sponsors. Without their support Lee would have to triple the registration fees and probably put the conference out of reach for many of the attendees.
