The Cisco Catalyst Wireless 9164I Wi-Fi 6E Access Point is an enterprise-class tri-band (2.4 GHz, 5 GHz, 6 GHz) access point. The AP supports full interoperability with leading 802.11ax and 802.11ac clients and a hybrid deployment with other APs and controllers.

The AP hardware is supported on the following platforms:

• Cisco Catalyst Center (earlier known as Cisco DNA Center) on-premises

• Cisco Catalyst stack

• Meraki cloud-based stack

The CW9164I AP is a tri-band Wi-Fi 6E enterprise indoor access point designed to work with the Cisco Catalyst 9800 Series Wireless Controller. The AP includes the following hardware and supporting features:

• Five radios:

  • A 4x4:4 6-GHz radio

  • A 4x4:4 5-GHz radio

  • A 2x2:2 2.4-GHz radio

  • A tri-band scanning radio for Cisco CleanAir Pro

  • A 2.4-GHz IoT (BLE) radio

• Integrated internal antennas that are omnidirectional in azimuth for the 2.4-GHz, 5-GHz, and 6-GHz bands.

• Scanning radio uses two 2.4-GHz, 5-GHz, and 6-GHz antennas.

• Multiuser Multiple-Input Multiple-Output (MU-MIMO) technology for uplink and downlink.

• Orthogonal Frequency Division Multiple Access-based (OFDMA-based) scheduling for both uplink and downlink.

• The following hardware external interfaces:

  • 1x100/1000/2500 Multigigabit Ethernet (RJ-45)

  • RS-232 Console Interface through RJ-45

  • Recovery push button (enables partial or full system configuration recovery)

  • USB 2.0 port, type-A connector

  • DC 54V power jack

  • One multicolor LED

• Integrated Bluetooth Low Energy (BLE) radio to enable IoT use cases such as location tracking and wayfinding.

• Intelligent Capture probes the network and provides Cisco Spaces with deep analysis.

• Spatial Reuse (also known as Basic Service Set [BSS] coloring) that allows APs and their clients to differentiate between multiple BSS, thus permitting more simultaneous transmissions.

• Power savings mode called Target Wake Time (TWT), which allows clients to stay asleep and wake up only at prescheduled (target) times to exchange data with the AP. This provides significant energy savings for battery-operated devices.

• Cisco Catalyst Center (earlier known as Cisco DNA Center) support to enable Cisco Spaces, Apple FastLane, and Cisco Identity Services Engine.

• Optimized AP Roaming to ensure that client devices associate with the AP in the coverage range that offers the fastest data rate available.

• Cisco CleanAir Pro technology supports 2.4-GHz, 5-GHz, and 6-GHz bands. CleanAir Pro delivers proactive, high-speed spectrum intelligence across 20, 40, and 80, and 160-MHz-wide channels to combat performance problems arising from wireless interference.

• Cisco Software-Defined Access (SD-Access) deployment is supported.

The AP supports lightweight deployments (using Catalyst 9800 Controllers). The AP also supports the following operating modes:

• Local mode: This is the default mode for the AP. In this mode, the AP serves clients. The AP creates two CAPWAP tunnels to the controller, one for management and the other for data traffic. This is known as central switching because the data traffic is switched (bridged) from the AP to the controller where it is then routed.

• FlexConnect mode: In FlexConnect mode, the data traffic is switched locally and is not sent to the controller. In this mode, the AP behaves like an autonomous AP, but is managed by the controller. Here, the AP can continue to function even if connection to the controller is lost.

• Monitor mode: In this mode, specified Cisco APs can exclude themselves from handling data traffic between clients and the infrastructure. These APs act as dedicated sensors for location-based services (LBS), rogue AP detection, and intrusion detection system (IDS).When APs are in monitor mode, they actively monitor the airwaves and typically, do not serve clients.

• Sniffer mode: In this mode, the AP starts sniffing the air on a given channel. It captures and forwards all the packets from the clients on that channel to a remote machine that runs AiroPeek NX or Wireshark (packet analyzers for IEEE 802.11 wireless LANs). This includes information on timestamp, signal strength, packet size, and so on.

  Note	In the sniffer mode, the server to which the data is sent should be on the same VLAN as the wireless controller management VLAN. Otherwise, an error message is displayed.

• Site Survey mode: The AP GUI is enabled and is used for configuring the RF parameters for site survey investigation. For information, see the Access Points Survey Mode section in the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide.

Verify whether the AP model you have is approved for use in your country. To verify approval and to identify the regulatory domain that corresponds to a particular country, see https://www.cisco.com/c/dam/assets/prod/wireless/wireless-compliance-tool/index.html. Not all regulatory domains have been approved. As and when they are approved, this compliance list is updated.

Note	The x in the model numbers represents the regulatory domain.
