The opinions expressed in this editorial are those of the author and do not necessarily reflect those of Decima Reports. At the end of last year, Report on Wireless noted in this space that the year 2006 would be the year of fixed wireless deployments. It does appear to be shaping up that way, but there will be other key happenings on mobile side of the industry as well this year.  First and foremost, now that wireless number portability has been decided and there is some certainty as to when it will become available in the country’s major centres, the national players can get back to their raison d’être: beating each other up in the marketplace.  Each will strive to offer the best deal on handsets, features and minutes – all, of course, with the signing of a three-year contract. And when quarterly results reveal slower than anticipated subscriber growth for a particular operator, the company in question will accuse the others of acting irrationally in the market.  Wireless data services such as text and picture messaging, ringtones and music downloads will become increasingly important marketing and promotional tools going forward. While there is still tremendous upside for wireless operators in Canada to grow their base, increasing their per-subscriber revenue will be particularly key.  Messaging will likely remain one of the key wireless data drivers in the future. Business professionals will continue to adopt mobile email either through the BlackBerry or new competing services. Young people will text or instant message at an increasing rate. Multimedia messaging or MMS will also be a significant revenue driver as the number of camera phones continues increase.  Voice is still king in the Canadian mobility space, generating more than 90% of per user revenue. But data services represent the future and the carriers know it.
