• 6 GHz: 4x4 MIMO
• 6 GHz Channel Width: Up to 160 MHz
• 5 GHz Channel Width: Up to 80+80 MHz
• 2.4 GHz Channel Width: Up to 20 MHz
• Maximum PHY Rate: Up to 7.78 Gbps
• Wireless Technologies: OFDMA, MU-MIMO, TWT, BSS Coloring and beamforming
• Security: WPA3 support

5G Multigigabit Ethernet

A built-in 100M/1000M/2.5G/5G Multigigabit Ethernet RJ-45 interface provides high-speed wired connectivity between the access point and the network infrastructure. The 5G Ethernet interface is designed to support the high throughput generated by Wi-Fi 6E clients.

The access point also provides an RJ-45 management console port and a USB 2.0 Type-A interface capable of up to 4.5W under supported power configurations.

Integrated Antennas and XOR Technology

The CW9166I-ROW features integrated internal omnidirectional antennas designed for indoor enterprise deployments. The Catalyst 9166I platform includes dedicated radio paths for 2.4 GHz, 5 GHz and 6 GHz operation together with an XOR radio that provides flexible 5 GHz and 6 GHz deployment options.

• 2.4 GHz Antenna Gain: 3 dBi
• 5 GHz Antenna Gain: 5 dBi
• 5 GHz XOR Antenna Gain: 5 dBi
• 6 GHz Antenna Gain: 4 dBi
• Antenna Type: Integrated internal omnidirectional
• Bluetooth: Bluetooth Low Energy

Cisco's XOR functionality allows the wireless radios to be configured for dual 5 GHz operation or for 5 GHz plus 6 GHz operation, depending on the deployment configuration and applicable regulatory requirements.

IoT and Environmental Capabilities

Beyond high-performance Wi-Fi, the Catalyst 9166I platform integrates additional capabilities for enterprise IoT and infrastructure monitoring. This helps organizations build wireless networks that can support connected devices, monitoring and location-aware enterprise applications.
