Enterprise Wi-Fi 6E Connectivity

The Cisco CW9166I-B is part of the Cisco Catalyst 9166I Series and supports the latest IEEE 802.11ax / Wi-Fi 6E technology. Its tri-band architecture operates across 2.4 GHz, 5 GHz and 6 GHz, providing additional wireless capacity and reducing congestion in demanding enterprise environments.

The access point provides 4x4 MIMO with four spatial streams across the primary 2.4 GHz, 5 GHz and 6 GHz radios and can deliver up to 7.78 Gbps PHY data rate under specified channel and radio configurations.

Key Features

Advanced Radio Architecture

The CW9166I-B uses Cisco's advanced radio architecture with integrated internal omnidirectional antennas and an XOR radio. The XOR radio provides additional flexibility by allowing capacity to shift between 6 GHz and a secondary 5 GHz radio according to network requirements.

Cisco also integrates an IoT radio and environmental sensors into the Catalyst 9166I platform. The environmental sensors can monitor parameters including temperature, humidity and total volatile organic compounds (TVOC).

5G Multigigabit Ethernet

A built-in 100M/1000M/2.5G/5G Multigigabit RJ-45 Ethernet port provides high-speed wired connectivity between the access point and the network infrastructure. The 5G Ethernet interface helps support high-density wireless deployments without creating a conventional 1Gbps wired bottleneck.

Power and Installation

The Cisco CW9166I-B supports multiple power options, including 802.3bt Cisco UPOE, 802.3at PoE+ and 54V DC power. Cisco also specifies support for compatible Cisco power injectors.
