Method and system for localization-based data connectivity transitioning

A method and a system of maintaining data connectivity between a mobile device during traversal of a pedestrian facility and a server computing device via a set of intermediary communication devices. The method, executed in a processor of the server device, comprises while the mobile device is in data connectivity via a first intermediary communication device, receiving an indication that the mobile device is localized to a position between a first and a second intermediary communication devices of the set of intermediary communication devices, based on an inertial sensor device including at least one of a gyroscope, an accelerometer and the magnetometer, determining a directional heading of the mobile device, inferring, based on the directional heading, at least one of an unobstructed line of sight wireless signal transmission path to the second intermediary communication device, and a more obstructed line of sight wireless signal transmission path to the first intermediary communication device, and based on the inferring, maintaining the data connectivity with the mobile device by switching from the first intermediary communication device to the second intermediary communication device.
