InterDigital Communications Device-to-Device Technology Enhances capacity and coverage in urban environments.
In a typical dense urban environment cellular coverage can be spotty, especially indoors.
Base stations are placed at or near intersections.
Where they will provide the greatest coverage to outside users.
Red: Blazing data connection.
Blue: Weak data connection.
Black: No data connection. 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.
Excellent coverage on the street.
When moving farther indoors, the cellular signal can quickly deteriorate.
And coverage can be spotty.
With some receiving high quality service.
And others receiving poor service - or no service at all.
With Device-to-Device Communications users seeing a strong signal help nearby users with a weak signal.
This greatly enhances coverage and restores services for users near the interior of the building.
Local traffic can also be offloaded from the network.
Before - without the use of InterDigital's device-to-device network, many interior areas have poor or no coverage.
With InterDigital's Device-to-Device Technology, coverage and edge-capacity are enhanced 100 percent or more.
