As a former Nokia executive turned consultant and speaker, Tomi Ahonen has bolstered his reputation in the mobile industry by authoring six bestselling hardcover books and three eBooks. His latest book, The Insider’s Guide to Mobile, is a free eBook which details “the customers, services, apps, phones and business of the newest trillion dollar industry.”

The book marks Tomi’s tenth publication, and to celebrate the anniversary he asked Layar CEO Raimo van der Klein to author the book’s foreword. In it, Raimo details his own history in the mobile industry, including his time with Nokia and KPN, as well as his formation of Mobile Monday Amsterdam with fellow Layar co-founders Maarten and Claire.

Additionally, he explains his vision of where the mobile industry lies today.

“Basically now we have entered the third wave of mobile. First was Communication, second was Content and now the third is Context. We are barely scratching the surface of this third wave,” he writes. “The exciting stuff is happening in the middle, between the organized data in the cloud and the actual ‘dumb’ sensor information. In the complete history of content we have never been confronted with creating sensor based dynamic services that fit the context of a user. […] I consider this phase in mobile to be the phase where we will see the true face of this medium.”

You can read the entirety of Raimo’s foreword over on Tomi’s blog, Communities Dominate Brands, and to download Tomi’s free eBook, The Insider’s Guide to Mobile, head on over to the book’s page on Lulu.
