17. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, the operations comprising:
processing respective time-ordered pairs of network events associated with a mobile device, in which the respective time-ordered pairs indicate respective handovers in cell towers, comprising:
evaluating a pair of network events that did not result from handover of the mobile device from one cell tower to an adjacent cell tower;
determining an estimated speed of travel of the mobile device based on data from the pair of network events;
determining whether the estimated speed of travel of the mobile device indicates potentially improper mobile device usage; and
in response to determining that the estimated speed of travel of the mobile device indicates the potentially improper mobile device usage, generating an alert.
