Disclosed are apparatus and corresponding methodologies for data control in an electronic access control system. A plurality of electronic locks are connected to a central server over a network such as an 802.11 WiFi wireless network that may be used to provide data updates and management for the individual electronic locks. To address power management problems associated with electronic locks having the capability to communicate over an 802.11 WiFi network, the present disclosure provides method and apparatus for selectively powering on and off an 802.11 WiFi communications module integrated into the electronic lock to conserve power resources. An electronic access control system is disclosed which allows efficient data exchange between a central server and a plurality of electronic locks using a database structure, and which allows for multiple simultaneous database manipulations in a cost effective manner.
