Abstract
Since the FCC allocated a huge 7 GHz piece of the spectrum around 60 GHz for unlicensed use, there has been great interest in this band for high data rate wireless applications, such as wireless video. In this paper I explore the potential of the 60 GHz band for use in transmitting real-time neural imaging data. The setup consists of a mouse, free to move around a cage, with a camera attached to its skull recording neural activity. The channel is modeled via ray-tracing in order to extract receive power as a function of location, as well as delay spread. Results of various configurations that alter the material of the cage and position of the receiver are presented. While the model is a start to assessing the feasibility of this communication system, much more detail must be added before it is an accurate predictor of system performance.
The Matlab code used to perform the simulations:
- Simulation code: model_60ghz.m
- Wrapper to run several simulations: run_model.m
