It’s hard to imagine communicating without Skype, Facetime, X-Box, Twitter or a text on your smartphone. Mobile devices and other Internet Protocol (IP)-based services powered by high-speed broadband have revolutionized the way we connect with one another at just about every moment of our lives.

Millions of Americans are now abandoning traditional, copper-wire phone service. In just the past three years, U.S. smartphone adoption has increased from 16.9 percent to 54.9 percent, according to Nielsen. One out of three homes in the United States now relies on wireless-only technologies, according to the National Health Interview Survey.

Copper telephone technology has limited capabilities. It falls short in providing robust, high-speed Internet services that support IP-enabled applications such as Voice over Internet Protocol. Nor can it offer the next-generation healthcare, education and public-safety IP-based applications that consumers demand. Shifting our nation’s communications networks to all-IP is critical to ensuring consumer access to the most modern communications services.

As with the adoption of any new technology, the move to IP networks offers challenges and opportunities. A majority of Americans have already changed from voice-only telephone networks. Roughly 93 percent of U.S. households subscribed to switched-access phone service a decade ago, according to USTelecom, today it’s less than one-third and is projected to decline to one-quarter of households by the end of 2013.

Moving the dwindling number of consumers still on copper technology will likely require a public-private partnership that can ensure no one is left behind while also providing access to affordable 21st century technologies.
