|InterDigital device-to-device communications technology enhances capacity and coverage in urban environments. In a typical dense urban environment, cellular coverage can be spotty, especially indoors, since most basestations are typically placed at or near intersections where they will provide the greatest coverage to outdoor users. Often coverage can be poor in the center of large structures, as signals may be blocked by concrete and steel. Poor indoor coverage can be solved with additional small cell deployments, but this is costly and sometimes not possible.
That is where device-to-device communications provide a novel approach to solving poor coverage conditions, since users with a strong signal help nearby users with a weak signal — this greatly enhances coverage and restores service for users near the interior of the building. Local traffic can also be offloaded from the network. With InterDigital’s device-to-device technology, coverage and capacity are enhanced 100% or more.
