Abstract

Method for establishing wireless networks between devices is disclosed. When a first device is activated to establish a wireless network with other devices, a first activation reference time is recorded. At least one second device that has at least one compatible networking capability is searched for and identified. When the second device is activated to establish wireless network with other devices, a second activation reference time also is recorded. The first and second activation reference times are compared to determine whether they fall into the same time window. The offset between the system time of the first device and that of the second may be factored into the calculation to further enhance the accuracy. If the first and second activation reference times are in the same time window, the authentication of wireless network is established between the devices.
