US 9,439,205 B1 · Location based wireless network optimization in embedded systems

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.

Dependent claims

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.

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 a potential route towards the destination that the transportation vehicle likely takes;
comparing the potential route against a list of blackout areas to identify one or more blackout areas through which the transportation vehicle likely will travel, each of the blackout areas being known to have significant wireless interference cause by access points in the blackout areas;
conducting a counter measure by the onboard computing device to remedy anticipated wireless interference in the identified 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 identified blackout areas.

2 more elements

An onboard computing device configured to be placed in a transportation vehicle, comprising:

a wireless networking interface configured to establish a mobile wireless network connection with a mobile device, the wireless network interface further configured to detect signals of nearby access points in a region in which the transportation vehicle travels;
an output component configured to deliver a presentation in real time when the wireless networking interface continues receiving data streams for the presentation from the mobile device;
a processor configured to identify a blackout area based on the detected signals of nearby access points, wherein the blackout area has wireless interference from the nearby access points to impact the real-time receiving of data streams for the presentation.
