Inside the U.S., the race for the 4G market is well underway. The first wave of products launched this summer and many more are coming. Currently though, the infrastructure for 4G technology is just not in place yet for most providers. Over 25 operators are committed to 4G but only a handful has products on the market at the moment. Visit www.stockcall.com/ to see how companies in this industry have grown over the past years and how they are expected to perform in the future.

Outside the U.S., the 3G market is still competitive. Mexico President Felipe Calderon recently called for the freeing up of the 700 MHz band which is used for several types of wireless communications. The President also accelerated television digitalization efforts by 6 years. The moves create a shift away from the monopolies held by top Mexican media companies and has led to an auction type environment for foreign companies looking to play a role in the 3G telecommunications boom south of the border.

Both the 4G and 3G races in U.S. and Mexico are providing a boost for wireless companies like NII Holdings Inc. Wireless technology is always new somewhere and there is very little shortage of demand. A recently published report estimates that over 5 billion people have subscribed to some form of wireless services.
