Industry-leading Wi-Fi 6E for large, mission-critical deployments on-premises or in the cloud

  •  Five radios: 2.4 GHz (4x4), 5 GHz (4x4), 6 GHz (4x4), IoT radio, and band steering radio
  • Cisco CleanAir Pro for interference-free Wi-Fi  
  • XOR Radio, which allows dual 5 GHz usage

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

The Cisco Catalyst 9166 series Wi-Fi 6E access points enable operation in the 6GHz band to produce a network that is more reliable and secure, with higher throughput, more capacity, and less device interference. These access points provide three 4x4 radios and a host of cutting-edge features, including integrated environmental sensors and IoT radios. The Catalyst 9166 Series even offers an internal directional antenna model - the Catalyst 9166D1 - designed for use cases and areas with high ceilings such as auditoriums, warehouses, and other large open space areas. The Catalyst 9166D1 should be leveraged where typically external antennas would be required. And because the Catalyst 9166D1 uses a built-in directional antenna, it eliminates the need for additional hardware to achieve ideal wireless coverage.  
Operational management is flexible because customers can 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, saving you money as you network your way.  
With the industry’s leading on-premises network platform (Catalyst) joining the industry’s leading cloud IT platform (Meraki), these access points provide an unparalleled network experience. For organizations that need a wireless solution to deliver a reliable, flexible, and superior experience for your users, the Cisco Catalyst 9166 Series Access Points are the best choice.  
Table 1.           Catalyst 9166 Series features and benefits

Feature

Benefits

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 6GHz frequency band.

XOR radio

The dual-band XOR radio in the Catalyst 9166 Series enables shifting capacity between 6GHz and a secondary 5GHz 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.

(Available Fall 2023)

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 applies Cisco’s industry leading RF Interference detection and classification to the 2.4GHz, 5GHz, and 6GHz bands.

Client steering

Enhanced to help clients that are 6GHz capable to leave the 5GHz radio and connect to the 6GHz radio. Wi-Fi 6E clients are automatically directed to connect to the 6GHz radio to take advantage of the benefits it offers and free up the 2.4GHz and 5GHz 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) allow 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 management mode

The Catalyst 9166 Series can be managed either on-premises with Catalyst 9800 Series Wireless Controllers or cloud-managed through the Meraki Dashboard. It gives you the flexibility to deploy the access points in one management mode and shift to a different management mode in the future.
