Short range RF monitoring system
First Claim
1. A wireless short range radio-frequency master device being a mobile telecommunications device adapted to maintain a portable private network of wireless short range radio-frequency slave devices, wherein the master device is configured to:
- receive, at a plurality of orientations of the master device, a plurality of signals from two or more slave devices, wherein the plurality of signals are transmitted using variable strengths,determine, by comparing strengths of the plurality of signals, a calculated proximity of the two or more slave devices with respect to the master device, wherein the calculated proximity is associated with a physical distance between the master device and a slave device,determine from differences in the strengths of the plurality of signals, a direction of the two or more slave devices relative to the master device,enable definition of a set of slave devices selected from the two or more slave devices, andbased on the determined calculated proximity and the determined direction, enable a user to monitor members of the set.

Abstract
A wireless short range radio-frequency master device adapted to create and maintain a portable private network of wireless short range radio-frequency slave devices wherein the master device is configured to detect and register suitable slave devices for a network, and is capable of determining the proximity of any registered slave device with respect to the master device in use, the master device further being adapted to enable a user to define two or more groups of registered slave devices selected from the total number of registered slave devices and to enable a user to select a defined group of such registered slave devices as an active group, thereby forming an active portable private network of wireless short range radio frequency devices comprising the master device and selected registered slave devices within the selected group.
