The Insight Research Corporation's new analysis [1] finds that "wireless revenue will approach almost 49 percent of all telecommunications services revenue by the close of 2006 and will grow to 55.6 percent of all telecommunications industry revenue by 2010." While one can read a report excerpt [2], the full report runs $995 (ouch!).
Here's a look at wireless subscriber growth between 2005 and 2011:

Mirroring the continuing stagnation in broadband penetration in the United states, Insight Research finds that wireless market growth will be slower in North America than in many other locations surveyed around the world:
- North America (NA) has the slowest growth rate at 3.9 percent annually, but maintains its position as the region with the largest telecommunications services revenue in 2005. As the most mature telecom services market, NA growth is most dependent on new services as opposed to subscriber growth. Europe/Middle East/Africa (EMEA) exhibits a slightly higher growth rate at 4.5 percent per year, due to growth in the wireless market and growth from less developed sub-regions of Eastern Europe, the Middle East, and Africa.
The faster-growing regions are Latin America and the Caribbean (LAC) and Asia/Pacific (AP). LAC is dominated by the fast-growing economies of Mexico and Brazil. Many of the countries in the LAC region have a combination of a rapidly expanding middle class and increased privatization of key industries. The resulting pent-up demand for telecommunications services, much of which is satisfied by wireless services, is reflected in its high CAGR relative to the worldwide composite.
The AP region is experiencing the highest five-year growth overall, at 9.3 percent, and will be the largest telecommunications revenue producer, overtaking NA by 2007.
