Technical Specs

• Dynamic network discovery and self-healing network capabilities that based on IPv6, IEEE 802.15.4 e/g, IETF 6LoWPAN, and
IETF RPL.
• Robust security functionality including Advanced Encryption Standard (AES) 128-bit encryption, IEEE 802.1X, and IEEE
802.11i based-mesh security.
• WPAN module firmware upgrade functionality.
• WPAN module interface statistics and status.
The IEEE 802.15.4e/g WPAN module hardware contains the following:
• Microcontroller, an RF transceiver operating in the 902-to-928 MHz ISM band.
• Frequency synthesizer.
• RF Micro Devices RF6559 front-end module.
Cisco Resilient Mesh has no physical user interfaces such as buttons or display, and therefore all configuration and management
occur through Constrained Application Protocol (CoAP) Simple Management Protocol (CSMP) from Cisco IoT Field Network
Director (IoT FND). The application module can implement its own user interface and display information obtained using CSMP.
Cisco Resilient Mesh uses the communication module hardware in a way that is compliant with the IEEE 802.15.4e/g MAC/PHY
specification. Cisco Resilient Mesh uses the following PHY parameters:
• Operating Band: 902 to 928 MHz
• Channel Spacing: 400 kHz
• Modulation Method: Binary FSK
• 150k baud data rate, 75-bit rate due to FEC
• Maximum output Power: 28 dBm. See Configuring Transmit Power, on page 28.
Up to two WPAN modules can be installed in any of the slots of the CGR 1120 and CGR 1240.
