Abstract
In some examples a method includes receiving, with an Access Point (AP), a request from a wireless device to access a network through the AP; determining, with the AP via beamforming of a fixed antenna array of the AP, whether an angle of the wireless device relative to the fixed antenna array is within a first predetermined range; determining, with the AP, whether a received signal strength between the AP and the wireless device is within a second predetermined range; and granting, with the AP, the wireless device access to a network through the AP when it is determined that the angle of the wireless device relative to the fixed antenna array is within the first predetermined range and the received signal strength is within the second predetermined range.
Claims20
A method comprising:
- receiving, with an Access Point (AP), a request from a wireless device to access a network through the AP;
- determining, with the AP via beamforming of a fixed antenna array of the AP, whether an angle of the wireless device relative to the fixed antenna array is within a first predetermined range;
- determining, with the AP, whether a received signal strength between the AP and the wireless device is within a second predetermined range;
- and
- granting, with the AP, the wireless device access to a network through the AP when it is determined that the angle of the wireless device relative to the fixed antenna array is within the first predetermined range and the received signal strength is within the second predetermined range.
A non-transitory machine readable storage medium having stored thereon machine readable instructions to cause a computer processor to:
- determine, based on a beamforming index between an Access Point (AP) and a wireless device, an angle of the wireless device relative to the fixed antenna array;
- determine, based on a received signal strength between the AP and the wireless device, a distance between the AP and the wireless device;
- allow data communication between the AP and the wireless device only when it is determined that the angle of the wireless device relative to the fixed antenna array is within a first predetermined range and the distance between the AP and the wireless device is within a second predetermined range.
A vehicle comprising:
- a vehicle body;
- a computing system secured to the vehicle body;
- an Access Point (AP) to allow an authenticated wireless device to wirelessly communicate with the computing system, the AP including:
- a processing resource;
- and
- a memory resource storing machine readable instructions to cause the processing resource to:
- refuse a communication from the wireless device when the AP determines that an angle of the wireless device relative to the AP is not within a first predetermined range, the angle of the wireless device relative to the AP being determined via beamforming of the AP.
