Abstract
A computer implemented method, apparatus, and computer program product for controlling a wireless access point range. In one embodiment, the process identifies a distance between the client device and the wireless access point in response to a request by a client device to access the wireless access point. The process allows the client device to access the wireless access point if the distance from the client device to the wireless access point is within the selected access range for the wireless access point.

9. A computer implemented method for calibrating a wireless access range, the computer implemented method comprising:
-
sending a data packet to a calibration client with a given time-to-live value; responsive to receiving a response from the calibration client, adding the given time-to-live value to a set of desired time-to-live values; and selecting a largest time-to-live value from the set of desired time-to-live values to form a selected time-to-live value. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

18. A system for controlling a wireless access range, the system comprising:
-
a wireless access point, wherein the wireless access point comprises; a calibration unit, wherein the calibration unit identifies a time-to-live value for defining a selected access range of the wireless access point; a timer, wherein the timer identifies a clock time that a data packet is received from a client to form a receive time, and wherein the data packet includes a clock time that the data packet was transmitted by the client to form a transmit time; and a controller, wherein the controller determines a distance from the client to the wireless access point based on the receive time and the transmit time and grants access to a wireless network to the client if the distance from the client to the wireless access point is within the selected access range. - View Dependent Claims (19, 20)
