ANR Project: GEOHYPE

Associating wireless information to physical location is an interesting feature that many applications can benefit from. This capability is known as geocasting.

GEOHYPE investigates physical solutions that enable the broadcasting of information to specific spatial locations, using limited infrastructures. From a scientific point of view, the problem is to find a way for a base station to wirelessly transmit data that are decodable only within desired areas. To overcome limitations of classical beamforming methods that necessitate large and complex antenna arrays, GEOHYPE proposes an original approach named Spatial Data Focusing. Instead of focusing the radiated power of a transmitter toward a particular direction, GEOHYPE aims to focus the data only. In other words, transmitted data are present everywhere but decodable only at the desired location.
