Location based wireless network optimization in embedded systems
First Claim
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, wherein the transportation vehicle is about to travel through a blackout area;
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.

Abstract
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.

12. A method of enhancing a wireless network connection in a transportation vehicle, comprising steps of:
-
maintaining a mobile wireless network connection between an onboard computing device placed in the transportation vehicle and a mobile device; identifying by the onboard computing device a destination towards which the transportation vehicle is going to travel; determining one or more blackout areas along a potential route towards the destination that the transportation vehicle likely takes; conducting a counter measure by the onboard computing device to remedy anticipated wireless interference in the blackout areas, to ensure that a user experience based on the mobile wireless network connection is not disrupted by the anticipated wireless interference in the blackout areas. - View Dependent Claims (13, 14, 15, 16, 17)
