Systems, methods, devices, and computer program products are described for using an out-of-band (OOB) radio integrated with the femtocell to implement various novel proximity detection techniques. Proximity detection of access terminals (ATs) in the femtocell's access control list (ACL) may be desirable to support femto connectivity and service provision, for example, in context of idle macro-to-femto handoffs, active macro-to-femto hand-ins, etc. When multiple ATs are in the ACL, and particularly when the ATs have different OOB implementations, optimizing proximity detection may involve balancing reliability against latency. Embodiments implement OOB proximity detection according to techniques that address reliability, efficiency, and/or fairness of proximity detection, even across unmanaged OOB networks and for ATs having different OOB implementations. |
