Wireless transmission and/or other functions of an access point (e.g., a femto access point) are controlled based on whether an access terminal is in the vicinity of the access point. For example, wireless transmission may be enabled or disabled based on whether an authorized access terminal is inside or outside a perimeter associated with the access point. An access terminal may send a message to control wireless transmission and/or other functions of the access point based on signals (e.g., pilot signals) the access terminal receives from other access points. For example, the access terminal may determine whether it is inside or outside the perimeter based on comparison of phase information derived from received macro pilot signals with phase information maintained at the access terminal. |
