Key Features

• Wi-Fi 6 and Wi-Fi 6E (802.11ax): The IEEE 802.11ax standard, also known as High-Efficiency Wireless (HEW) or Wi-Fi 6, builds on 802.11ac. It delivers a better experience in typical environments with more predictable performance for advanced applications such as 4K or 8K video; high-density, high-definition collaboration apps; all-wireless offices; and the Internet of Things (IoT). Wi-Fi 6E is Wi-Fi 6 “extended” into the 6-GHz frequency band
• XOR radio: The dual-band XOR radio in the Catalyst 9166 Series enables shifting capacity between 6 GHz and a secondary 5-GHz radio.
• Environmental sensors: These built-in sensors measure air quality (total volatile organic compounds [TVOC]), temperature, and humidity, and help ensure a safe working environment, avoiding the need to install an overlay of difficult-to-manage independent sensors.
• Zero Wait DFS: Allows for continuous monitoring of DFS channels for radar events thus enabling faster channel changes when needed. This enables RRM to minimize client distribution and maximize operational readiness.
• AP power optimizations (AP Power Save Mode): AP Power optimizations (AP Power save mode) allows the access point to reduce its power consumption by e.g. shutting off radios during off-hours and weekends – whilst still being smart enough to re-engage all features should they be needed. This both saves power and reduces the carbon footprint of running a wireless network.
• CleanAir^™ Pro: CleanAir^™ Pro extends Cisco’s industry leading RF Interference detection and classification into the 6 GHz band. 
• Band steering: Enhanced to help clients that are 6-GHz capable to leave the 5-GHz radio and connect to the 6-GHz one. Wi-Fi 6E clients are automatically directed to connect to the 6-GHz radio to take advantage of the benefits it offers and free up the 2.4- and 5-GHz radios for legacy clients.
• Uplink/downlink OFDMA: Orthogonal Frequency-Division Multiple Access (OFDMA)-based scheduling splits the bandwidth into smaller frequency allocations called Resource Units (RUs), which can be assigned to individual clients in both the downlink and uplink directions to reduce overhead and latency.
• Uplink/downlink MU‑MIMO technology: Supporting the highest number with 12 spatial streams, multiuser multiple input, multiple output (MU-MIMO) enables the access points to split spatial streams between client devices to maximize throughput.
• BSS coloring: Spatial reuse (also known as Basic Service Set [BSS] coloring) allows the access points and their clients to differentiate between BSSs, thus permitting more simultaneous transmissions.
• Target Wake Time: Target Wake Time (TWT) allows the client to stay asleep and to wake up only at prescheduled (target) times to exchange data with the access point. This offers significant energy savings for battery-operated devices, up to three to four times the savings achieved by 802.11n and 802.11ac.
• Intelligent Capture: Intelligent Capture probes the network and provides Cisco DNA Center with deep analysis. The software can track more than 240 anomalies and instantaneously review all packets on demand, emulating the onsite network administrator. Intelligent Capture allows for more informed decisions on your wireless networks.
• Application hosting: Application hosting helps simplify IoT deployments and ready them for the future by eliminating the need to install and manage overlay networks. Using the USB interface, containerized applications and hardware modules can be deployed to reduce cost and complexity. Adding Cisco DNA Center provides workflows and deployment-wide application lifecycle management.
• Bluetooth 5.1: The integrated Bluetooth Low Energy (BLE) 5.1 radio enables location-based use cases such as asset tracking, wayfinding, and analytics.
• Container support for applications: Container support enables edge computing capabilities for IoT applications on the host access point.
• Choice of persona: Cisco Catalyst 9166 Series Access Points can be managed either on-premises with Catalyst 9800 Wireless Lan Controllers (WLC) or cloud-managed through the Meraki dashboard. Customers have the flexibility to deploy these access points in one persona and shift to a different persona in the future.

About This Product
The Cisco^® Catalyst^® 9166 Series Access Points (AP) allows you to choose between on-premises and cloud management. They are the next-generation APs perfect for mission-critical deployments and support the new 6-GHz band for Wi-Fi. It is resilient, secure, and intelligent.

With the flexibility to choose between cloud- and on-premises management, the Catalyst 9166 Series Access Point ensures network investment protection and unlocks the power of hybrid work. The Wi-Fi 6E-compliant access point takes advantage of the 6-GHz band expansion to produce a network that is more reliable and secure, with higher throughput, more capacity, and less device interference. The access points come with three 4x4 radios and provide a host of cutting-edge features.

With the industry’s leading on-premises network platform (Catalyst) joining the industry’s leading cloud IT platform (Meraki), this access point provides an unparalleled network experience. For organizations that need solutions to power hybrid work, and that allow their people to work anywhere at any given time with elevated, secure, and connected experiences, the Cisco Catalyst 9166 Series Access Points are the best choice.

Operational management is not static, as customers are able to change their network management whenever they want. If a network with Cisco Catalyst 9166 Series Access Points was originally an on-premises deployment, it can be changed to cloud-based management without the need to purchase and redistribute additional hardware.
