60 GHz broadband MAC system design for cable replacement in machine vision applications

Authors: Marcus Ehrig, Markus Petri

Abstract:
In this paper, we present a wireless 60 GHz OFDM transceiver for a high-throughput GigE Vision standard compliant color CCD camera system used in machine vision applications. The OFDM transceiver provides net data rates up to 3.9 Gb/s. The medium access controller (MAC) offers the reliable GigE point-to-point cable replacement functionality with special support of an asymmetrical downlink scenario. The main focus is on the high throughput MAC design for frame based wireless transmissions and the integration onto a hardware platform. The OFDM baseband processor and the MAC were fully implemented in FPGA technology. The performance of the system was theoretically analyzed and measured in an indoor environment. The developed system fulfills the high throughput requirement as well as the low latency requirement of the used industrial HD video camera system.
