Location based wireless network optimization in embedded systems

摘要

Method and devices for optimizing wireless network connections in transportation vehicles are provided. An onboard computing device in a transportation vehicle identifies blackout area with severe wireless signal interference caused by nearby wireless access points in the blackout area. The wireless interference can be remedied by dynamically switching wireless channel for the in-vehicle wireless connection between the onboard computing device and a mobile device in the vehicle. The wireless interference can also be remedied by pre-caching the data needed for a content presentation during a time period when the vehicle travels within the blackout area.

主权项

1. A method of optimizing a wireless network connection in a transportation vehicle, comprising steps of:
establishing a mobile wireless network connection between an onboard computing device placed in the transportation vehicle and a mobile device on a first wireless channel; identifying by the onboard computing device a blackout area in a route along which the transportation vehicle travels, the blackout area having significant wireless interference to the mobile wireless network connection on the first wireless channel; determining by the onboard computing device a second wireless channel for the mobile wireless network connection, the mobile wireless network connection on the second wireless channel experiencing less wireless interference in the blackout area than the mobile wireless network connection on the first wireless channel; and switching by the onboard computing device the mobile wireless network connection to the second wireless channel, before the transportation vehicle reaches the blackout area.
