In the same on-stage conversation, Lauer said Qualcomm is doing long-term research into radio systems that might allow mobile devices to communicate directly with each other, bypassing the cellular network.

This technology could help carriers overcome the limitations of their networks, which won't get significant new radio spectrum for several years, he said. Such a system might use both licensed and unlicensed spectrum, but it would probably use a different, lower-frequency band than is used in cellular today, according to Lauer.

Qualcomm's research is internal, but other companies are exploring the same idea, he said. Cambridge University researchers recently published a paper on " pocket-switched networks " that would allow communication among wireless devices without the need for cellular networks. Femtocells, tiny base stations that subscribers set up in their homes with their own broadband connections as wired network links, are a more immediate solution to the capacity problem but face challenges with interference, Lauer said.
