System and method for distance-dependent data exchange between wireless communication devices
First Claim
1. A method comprising:
- by a primary communication device, identifying a plurality of data types;
by the primary communication device, identifying a plurality of communication ranges for data transmission, wherein a first communication range of the plurality of communication ranges is less than a second communication range of the plurality of communication ranges, and wherein the first communication range corresponds to a first data type of the plurality of data types and the second communication range corresponds to a second data type of the plurality of data types;
by the primary communication device, transmitting data in the first data type to a first wireless communication device located within the first communication range, wherein the data in the first data type is transmitted using a first bandwidth based on the first communication range; and
by the primary communication device, transmitting data in the second data type to a second wireless communication device located within the second communication range, wherein the data in the second data type is transmitted using a second bandwidth based on the second communication range, the second bandwidth being lower than the first bandwidth, and wherein the data in the first data type is undecodable by the second wireless communication device at the second communication range.
