Abstract :
This paper presents a wireless high throughput data transmission system dedicated to interface implantable multi-channel neural recording devices. Its main component is a low-end wireless IEEE 802.11g compliant LAN router, which makes it very cost effective and reliable. The presented design is portable/wearable and, therefore, well suited for high data rate medical systems applications. Furthermore, it requires a very short development time, and presents a flexible user I/O interface. The router runs OpenWrt, a free Open Source Linux distribution for wireless routers. The proposed architecture has been prototyped with an Asus wireless router and achieves more than 6.1 Mbps of sustained throughput over the transmission control protocol (TCP).
