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.
Claims18
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, wherein determining the angle of the wireless device relative to the fixed antenna array includes determining an angle based at least in part on a beamforming index;
- determining, with the AP, whether a received signal strength between the AP and the wireless device is within a second predetermined range, wherein the second predetermined range is based at least in part on the determined angle of the wireless device relative to the fixed antenna array, the second determined range being a first range for a determined angle of a first angle value and a second range for a determined angle of a second angle value, wherein the first angle value is greater than the second angle value in relation to an axis for the fixed antenna array, and wherein the first range requires a stronger received signal strength for the wireless device than the second range;
- and granting, with the AP, the request from the wireless device to access the network through the AP when it is determined that the determined 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,
- wherein granting the request comprises sending a response to the wireless device, the response comprising a plurality of association information to facilitate allowing the wireless device access to the network through the AP.
A non-transitory machine readable storage medium having stored thereon machine readable instructions to cause a computer processor to:
- receive a request from a wireless device to connect to a network through an Access Point (AP);
- determine, based on a beamforming index between the AP and the wireless device, an angle of the wireless device relative to a fixed antenna array of the AP, wherein
- determining the angle of the wireless device relative to the fixed antenna array includes determining an angle based at least in part on a beamforming index;
- determine, based on a received signal strength between the AP and the wireless device, a distance between the AP and the wireless device;
- and
- grant the request only when it is determined that the determined angle of the wireless device relative to the fixed antenna array of the AP is within a first predetermined range and the determined distance between the AP and the wireless device is within a second predetermined range, wherein the second predetermined range is based at least in part on the determined angle of the wireless device relative to the fixed antenna array of the AP, the second determined range being a first range for a determined angle of a first angle value and a second range for a determined angle of a second angle value, wherein the first angle value is greater than the second angle value in relation to an axis for the fixed antenna array, and wherein the first range requires a shorter distance between the AP and the wireless device than the second range;
- wherein granting the request comprises wherein granting comprises sending a response to the wireless device, the response comprising a plurality of association information to facilitate allowing the wireless device access to the network through the AP.
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;
- a fixed antenna array;
- and a memory resource storing machine readable instructions to cause the processing resource to:
- refuse a communication request from the wireless device to access the computing system through the AP when either:
- the AP determines that an angle of the wireless device relative to the fixed antenna array is not within a first predetermined range, the angle of the wireless device relative to the fixed antenna array being determined via beamforming of the AP, or the AP determines that a distance between the AP and the wireless device is within a second predetermined range, wherein the second predetermined range is based at least in part on the determined angle of the wireless device relative to the fixed antenna array, the second determined range being a first range for a determined angle of a first angle value and a second range for a determined value of a second angle value, wherein the first angle value is greater than the second angle value in relation to an axis for the fixed antenna array, and wherein the first range requires a shorter distance between the AP and the wireless device than the second range;
- wherein refusing the communication request comprises the AP refusing to transmit a plurality of association information to the wireless device to facilitate allowing the wireless device access to the computing system through the AP.
