Coupling and De-Coupling Sets - Two sets are capable of being connected as one network. When one set is within wireless range of another set, the Smart Redundant Carriage Coupling (SRCC) technology will verify the other set’s credentials and, if acceptable then the two will become connected together (one Virtual Ethernet network).
A virtual Ethernet network is established between cars and between sets using the IEEE 802.11 wireless technology.
The Smart Redundant Carriage Coupling (SRCC) technology only connects with other SRCC technology with the correct credentials. A Pre-Shared Key (PSK) provides a very high level of security for the system with a password (PSK) of 8 to 63 characters long being utilised.
Furthermore, the radio links are protected by Wi-Fi Protected Access 2 - Pre-Shared Key (WPA2-PSK). WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.
Wireless Network Configuration - The IEEE 802.11 Wireless Local Area Network operates in the 5 GHz unlicensed Low Interference Potential Devices (LIPD) band. The Smart Redundant Carriage Coupling (SRCC) is utilised for inter-set connectivity.
