Since 1993, Wavecom has been innovating, developing and selling wireless pre-packaged solutions

for automotive and machine-to-machine (M2M) markets and continues to see a significant growth

opportunity in these markets. However, due to the need to converge two different worlds: the

industrial world and the cellular communication world, some issues remain to be addressed in order to

accelerate adoption. These two very different worlds already have ownership of their own separate

standards that have been designed from conception without taking into account the potential interconnections

with each other.

By offering a large family of Wireless CPUs (Central Processing Unit) that can be programmed with

application software by using Wavecom’s Open AT® Software Suite and Integrated Development

Environment (IDE), both the industrial and cellular worlds can interact seamlessly and efficiently.

The combined offer enables the deployment of automotive or M2M end-to-end solutions that are cost

effective, scaleable, powerful, reliable and interoperable. This singular offering is based on the most

flexible and open solution on the market today that comes with no added developer licensing fees

charged for the Open AT® Software Suite and its IDEs. So, to take advantage of this technology, no

major capital outlays are required for the initial development.

The first version of Open AT® software was launched in 2001 and currently, more than four million

Open AT®-based solutions are working in a variety of vertical product applications. The company is

continuing its rollout plan by launching the fourth generation of the Open AT® Software Suite at the

end of 2006. In the future, Wavecom will enable all automotive and M2M technology providers to

become Open AT® licensees.

Numerous customer testimonials demonstrate the unique and unsurpassed power of the Open AT®

Software Suite and prove that businesses can join this growing community in order to drive its

adoption to the point where it becomes the recognized standard for the automotive and M2M markets.
