Abstract
A wireless communications device receives information about the locations of other wireless communications devices from those other wireless communications devices, uses the location information to determine what directions those other wireless communications devices are from it, and creates a directional transmission to focus the transmission in the direction of one or more of those other wireless communications devices.
Claims12
A system, comprising:
- a first wireless device to:
- communicate with multiple mobile wireless devices;
- obtain location information from the multiple mobile wireless devices about locations of the multiple mobile wireless devices;
- determine, based on the location information, a direction of each of the mobile wireless devices from the first wireless device;
- determine a range of directions that encompasses the directions of a group of the mobile wireless devices;
- and
- transmit a directional signal that encompasses the range of directions;
- wherein said obtaining the location information is not based on measuring directions from which the signals from the mobile wireless devices are received.
5 more elements
A method, comprising:
- receiving location information from multiple mobile wireless devices about locations of the multiple mobile wireless devices;
- determining, from the location information, a relative direction to each of the mobile wireless devices;
- grouping the relative directions into a group of relative directions that are within a range of relative directions;
- and
- transmitting a directional signal that encompasses the group of relative directions at one time.
2 more elements
A machine-readable medium that provides instructions, which when executed by a computing platform, result in at least one machine performing operations comprising:
- receiving location information from multiple mobile wireless devices about locations of the multiple mobile wireless device;
- determining, from the location information, a relative direction to each of the mobile wireless devices;
- grouping the relative directions into a group of relative directions that are within a group of relative directions;
- and
- transmitting a directional signal to encompass the group of relative directions at one time.
