Figure 32: Renesas CCU – WAVE-Box ver2
The RENESAS CCU is equipped with a SH4 microcontroller-based (32-bit RISC)
embedded system, having 128 MB Flash memory and 128MB DDR2-SDRAM
memory built in. It is using Linux-OS. Two units of WLAN modules for IEEE802.11p
communication, each having diversity option and a transmit power up to +21 dBm
have been integrated. It has a built in GPS reception module for synchronization,
which requires an external antenna. The following interfaces are provided:
1x Ethernet 10/100 Mbit/s
2x2 SMA for SCH and CCH/providing diversity option
Power input is DC 12V/15W max.
The software implemented in the Renesas CCU complies with European ITS
architecture of network & transport layer and access technology layer 11p
integrating all aspects of PreDRIVE C2X. As option, such software could be applied
to U.S architecture (IEEE11p and IEEE1609).
In detail, Renesas Communication Unit includes the following software:
Geo-networking functionality integrated by Hitachi. Such software, compliant
with GeoNET specifications, deals with Geo-networking algorithms namely,
network beaconing, Geo-unicast, Geo-broadcast, Geo-anycast and Topobroadcast.
User-friendly web-based configuration tool. The web-based configuration tool
(WCT) enables users to intuitively set up the parameters of access layer and
network & transport layer, that are, network interfaces and geo-networking
