New Features

New Features in Cisco IOS XE 17.14.x
The features in the following table are new in this release for the supported

1-Support for Class B End Devices in the LoRaWAN Network
Supported Devices: IR1101 and IR1800
The Cisco Catalyst IR1101 and IR1800 Routers now support Class B mode in LoRaWAN networks. This feature improves network efficiency and extends the battery life of end devices. It works by allowing the devices to open receive windows, known as ping slots, using time-synchronized beacons from the Cisco Wireless Gateway. These windows make it easier for the network server to send data to the end devices.

2-LTE450MHz PIM support on IR1800
Supported Devices: IR1800
The Cisco Catalyst IR1800 Rugged Series Router now supports the 450MHz Long-Term Evolution (LTE) Pluggable Interface Module (PIM), known as P-LTE-450. This module is specifically designed for LTE use cases in utility, public safety, and critical infrastructure sectors in Europe and other regions.

3-Support for CAPWAP and WGB Modes on the Cisco Wi-Fi Interface Module
Supported Devices: IR1800
The Cisco Catalyst IR1800 Rugged Series Routers now support CAPWAP and WGB Modes on the Cisco Wi-Fi Interface Module (WIM). From this release, you can:

1. Switch the operation mode between Control and Provisioning of Wireless Access Points (CAPWAP), and Workgroup Bridge (WGB).
2. Perform a factory reset and erase configuration.
3. Configure the radios for WGB uplink and concurrent Root AP mode operations.

4-Ethernet over MPLS Pseudowire
Supported Devices: IR8340
The Cisco Catalyst IR8340 Rugged Series Router supports Ethernet over MPLS (EoMPLS) pseudowire to transport Ethernet frames across a Multiprotocol Label Switching (MPLS) network. This feature integrates Ethernet-based services into the MPLS infrastructure to deliver Layer 2 connectivity.
