Title:
The method and system for exact distance-in-a-straight-line presumption for two sets of communication equipment
Document Type and Number:
Japanese Patent JP6177089
Kind Code:
B2
Abstract:
A method and system is provided for estimating proximity and accurately calculating the straight line distance between the communicating Bluetooth enabled portable communication devices. Particularly, the invention provides a method and system for capturing the received signal strength indicator (RSSI) values form at least one target communication device (204) by the reference communication device (202); calculating the constant values of properties of communication environment of the devices by utilizing captured received signal strength indicator (RSSI) values; and deriving accurate straight line distance between the reference communication device (202) and the target communication device (204) by utilizing calculated constant values of properties of communication environment of the devices.
