Abstract

Wireless devices are increasingly deployed in smart vehicles. As well as supporting user devices using Wi-fi and Bluetooth (for example), manufacturers are looking to reduce the weight of in-vehicle wiring by deploying wireless sensor networks to monitor and control some aspects of the vehicle and the environment within it.

The inside of a vehicle can typically be thought of as an electromagnetic cavity, with the shell forming a highly reflective boundary. This, however, creates a fundamental problem- the propagation of electromagnetic waves in cavities is not necessarily analogous to that in well understood existing wireless communications channels.

In this talk, two questions are addressed: How can we model the in-vehicle wireless communication channel ? What is the information capacity of this channel ?
