Generating neighbor lists. A set of devices are provisioned to report on neighbor lists and visibility of sectors. Each device in the set of devices generates event data that includes the neighbor list from a sector, other sectors visible while using the neighbor list, and/or sectors visible to the device if the call was dropped or lost. The event data can be recorded or stored by the device or forwarded to a server immediately or at a later time. The event data of each device is received at and recorded by a management system. The management system can derive recommended neighbor lists for each sector in a wireless network based on the cumulative event data received from the set of devices operating in the network.
