Cisco IR500 Series WPAN Gateway and Range Extender Installation and Configuration Guide
Chapter 5 Operation and Configuration
Information about WPAN Gateway and WPAN Range Extender Operation
CGRs provide wide-area connectivity for CGEs. In addition to providing wide-area connectivity,
because CGRs typically have more resources than CGEs, CGRs support critical functions for secure
network access control, routing, and management of CGEs. In a typical deployment, a single CGR may
provide wide-area connectivity for hundreds or thousands of CGEs.
CG-NMS provides the necessary back-end infrastructure
for supporting the CGEs
and CGRs in the
Cisco CG FAN. CG-NMS is responsible for managing secure network access, configurations, and
firmware updates for all CGR and CGEs in a CG FAN deployment. Each device registers with the
CG-NMS and periodically reports information that assists a network operator in assessing the health of
the network and diagnosing any issues that may occur.
The Cisco Industrial Routers (IR) 500 Series W
PAN
Gateway and WPAN Range Extender provide
unlicensed 902-to-928 MHz ISM-band wireless personal area networ
k (WPAN) communications to
diverse Internet of things (IoT) applications. Among the IoT applications supported are smart grid,
distribution automation (DA), and supervisory control and data acquisition (SCADA).
The devices supply radio frequency (RF) mesh connecti
vity to
one IPv4/Ethernet and serial IoT device,
including recloser control, cap bank control, voltage regulator controls, and other remote terminal units
(RTUs).
The devices provide an open standards RF mesh solution based on the following standards:
• IEEE 802.15.4 g/e
• IETF 6LoWPAN
• IETF Routing Protocol for Low Power and Lossy Networks (RPL)
• IETF Mapping of Address and Port—Translation (MAP-T)
• IETF Constrained Application Protocol (CoAP)

Role of the WPAN Gateway
The WPAN Gateway provides IPv4/IPv6 connectivity to DA Devices. The gateway connects to DA
Devices using serial ports (RS232/RS485) and, or an Ethernet port using IPv4. The gateway provides
remote connectivity to:
• serial DA devices over CG-Mesh by transporting serial data in TCP/IP
• IPv4 DA devices over the IPv6-based CG-Mesh by using Mapping of Address and Port using
Translation (MAP-T), as specified in draft-ietf-software-map-t
WPAN Gateway and Serial-based DA Devices
The CGR800-WPAN connects serial-based DA devices and exports them over the IPv6-based Field Area
Network by the following means:
• RS232/RS485 Port—the gateway RS232/RS485 serial port is used to connect RS232/RS485-based
DA devices and transport serial data traffic over TCP. The gateway configuration and management
of the serial port is done via CSMP and the CG-NMS.
