WAVE Project Based on iRadio

Introduction

Wireless Access in Vehicular Environments (WAVE) is the next generation dedicated short-range communications (DSRC) technology, which provides high-speed vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) data transmission and has major applications in intelligent transportation systems (ITS), vehicle safety services and Internet access. Operating at 5.850-5.925GHz, WAVE systems adopt orthogonal frequency-division multiplexing (OFDM) and achieve data rates of 6-27Mbs/s. In WAVE systems, a roadside unit (RSU) can cover a range of up to 1000 feet. WAVE systems are based on the IEEE 802.11p protocol, which is currently under development.

Objectives

The project targets establishing the first high-speed vehicular ubiquitous wireless console that can access Internet, enhance safety and connect with vehicular sensors and actuators and onboard wireless devices for drive monitoring, body control and infotainment. The project is currently funded by NSF, Office of Technology Transfer (OTT), University of Michigan.

WAVE Prototype

The WAVE onboard units (OBUs)/RSUs, each consisting of an RF front end, a field programmable gate array (FPGA) baseband processor, and a netbook for GUI and related MAC protocols, have a similar configuration at the physical layer, shown in Fig.1. Supported by a grant of Michigan University Commercialization Initiative (MUCI), in 2006-2008 we established an OBU/RSU prototype, upon which some preliminary results of the performances of WAVE systems are presented. Figure 2 shows the configuration of the OBU prototype. The OBU is capable of transmitting and receiving a test OFDM frame or live picture in a real-time mode where the baseband algorithms are performed by the FPGA.
