THE proposed merger of T-Mobile and AT&T will solve an inexorable need for increased network capacity and speed, and it advances the public interest in many different ways. That's why we at T-Mobile look forward to a speedy settlement of the Justice Department's lawsuit — a step that will allow consumers to enjoy the many benefits of this deal.

In the Seattle area alone, data traffic on T-Mobile's network has increased by approximately 500 percent in the past year. With the advent of smart mobile devices, stronger, faster and smarter networks are needed to keep pace with wireless data demand. Our company in particular and our industry in general are facing a serious challenge: The supply of wireless spectrum currently available in the United States for commercial use is running low.

Wireless spectrum is the government-controlled airwaves that wireless companies license to transmit wireless signals and provide wireless services. Just like a real-estate developer needs land to build communities and provide services, wireless carriers need spectrum to build wireless networks and service our customers.

Relying on the government to solve this is simply not a viable option, as proposed solutions such as a government-mandated reallocation of spectrum from national defense, broadcasters and commercial operators will take years to accomplish.

After carefully reviewing all the options available to solve these spectrum challenges, AT&T and T-Mobile concluded that joining forces is by far the most effective solution to our respective capacity issues. While this combination will not increase the overall supply of spectrum, it will significantly enhance the efficiency of our spectrum use, resulting in considerable improvements in service quality and a deployment of the next generation of mobile data speeds (4G LTE) to 97 percent of the U.S. population.

For current T-Mobile and AT&T customers, the merger will result in better coverage, fewer dropped and blocked calls, and faster and more consistent app performance and data downloads — particularly at peak times and in high-demand locations.

For existing and emerging technology companies, including many based right here in the Puget Sound, it will provide a stronger network of opportunities, such as continued innovation, improved productivity and more efficient delivery of products and services.

The combination of T-Mobile and AT&T will create the most innovative and customer-centric wireless company in the world; and the new AT&T will be a major force keeping the United States a technology, innovation and economic leader as the world races into an exciting wireless future.

We hope that the Justice Department will agree and allow the merger review process to continue.
