Cohda Wireless|Cohda XBU-V Specification | 25/03/2019 | Commercial in Confidence
Functional Specification
The current XBU-V is based on the Cohda MK5 platform and shares the functionality. The unit runs an Ubuntu
16.04 LTS, providing a flexible environment for running multiple applications. They will be briefly outlined
here.
Processor
The MK5 Application Processor is an NXP i.MX6 Dual Lite processor, providing the processing power for the ITS
applications. There is also a wide selection of services available to applications.
Communication Services
The MK5 system provides a range of communication services for ITS applications. All communication services
are integrated within the Linux networking system. The following network protocols are provided by the MK5
platform:
- IPv6, IPv4 (Linux networking stack)
- IEEE1609.3 WSMP and WME management (Cohda WAVE networking services)
- ETSI TC-ITS G5, GN, GN6 & BTP (Cohda TC-ITS networking services)
These communication protocols are available to operate over the following communication interfaces
available on the MK5 board:
- DSRC
- 10/100Mbps Ethernet
- USB 2.0
Ethernet
MK5 provides a 100Mbps Ethernet interface (10BASE-T/100BASE-TX) which can be used as part of an
application or alternatively used for debugging purposes or remote status and control. The Ethernet interface
is supported by Linux Ethernet device drivers, providing full IPv4/IPv6 over-Ethernet networking functionality.
Peripheral Interface Services
General purpose interface services are provided to allow interconnection with external peripheral devices and
systems.
USB-OTG (optional)
A USB 2.0 on-the-go (OTG) port is optionally available as an upgrade and is supported by Linux USB host and
peripheral device driver APIs.
Serial Console (optional)
The MK5 RSU provides an optional serial port upgrade via the expansion connector through which the primary
operating system console is available. This port is used primarily for system development and debug
operations, but may also be used by applications if required.
Timing and Positioning services
The MK5 XBU-V manages both timing and positioning services within the Cohda Mining Solution via our V2X-
Locate Engine and PTP setup.
The XBU-V also employs a u-blox8 M8U GNSS receiver with concurrent support for GPS and Galileo or
GLONASS constellations. The GPS receiver provides best in class tracking and navigation performance in
difficult urban canyon environments. The MK5 provides position fixes at rates of up to 10 fixes/sec.
