Radio frequency scan
First Claim
1. A method comprising;
- determining the location of a first portable electronic device, defining a search area dependent on the location of the first portable electronic device, receiving radio signals from a plurality of other electronic devices to determine the identities of the other electronic devices, the identities of the other electronic devices defining a first group of identified electronic devices, determining the respective locations of the plurality of other electronic devices, and comparing the location of each of the plurality of other electronic devices with the defined search area to create a second group of identified electronic devices, wherein the second group is a subset of the first group.

Abstract
It is provided a method for performing a radio frequency scan in a portable electronic device. The location of the portable electronic device is determined. It is defined a search area dependent on the location of the portable electronic device. The portable electronic device receives radio signals from a plurality of other electronic devices to determine the identities of the other electronic devices, the identities of the other electronic devices defining a first group of identified electronic devices. The respective locations of the plurality of other electronic devices are determined. The location of each of the plurality of other electronic devices are compared with the defined search area to create a second group of identified electronic devices, wherein the second group is a subset of the first group.
