The Cisco Catalyst 9136 series wireless access point is a tri-band (2.4 GHz, 5 GHz, 6 GHz), enterprise 802.11ax (Wi-Fi 6) AP. The AP has one model with integrated antennas and is designed to use the 2.4-GHz, 5-GHz, and 6-GHz bands. This AP supports a greater overall Cisco High Density Experience (HDX), which provides a more predictable performance for advanced applications such as 4K or 8K videos, high-density and high-definition collaboration applications, all-wireless offices, and Internet of Things (IoT). The AP supports full interoperability with leading 802.11ax and 802.11ac clients, along with mixed deployment with other APs and controllers. These APs provide integrated security, resiliency, and operational flexibility as well as increased network intelligence.

The C9136I AP is an enterprise-grade wireless access point designed to work with a Cisco wireless controller. The AP includes the following hardware and supporting features:

• Five radios:

  • A 4x4:4 6-GHz radio

  • A 8x8:8 5-GHz radio

  • A 4x4:4 2.4-GHz radio

  • A tri-band scanning radio

  • A 2.4-GHz IoT (802.15.4) radio

Note	The Bluetooth Low Energy (BLE) uses the Omni IoT radio.

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

• Scanning radio utilizes 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.

• Multigigabit Ethernet (mGig)

• The following hardware external interfaces:

  • 2x100/1000/2500/5000 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

  • One multicolor LED

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

• Link Aggregation Group (LAG) is supported.

  Note	LAG and dual ports are not supported when the AP is in SDA/fabric (local) mode. LAG mode is not supported in dual homed connection. When C9136 AP is deployed in Non-LAG, dual homed deployment, the VLANs of the switchover have to be same in both the switches.

• Intelligent Capture probes the network, and provides Cisco Catalyst Center (earlier known as Cisco DNA Center) 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 simultaneous transmissions.

• Power savings mode called Target Wake Time (TWT), which allows a client 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 supports to enable Cisco Spaces (earlier known as Cisco DNA 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 technology enhanced with 160-MHz channel support. CleanAir delivers proactive, high-speed spectrum intelligence across 20, 40, 80, and 160-MHz-wide channels to combat performance problems arising from wireless interference.

The AP supports lightweight deployments (using Cisco Wireless 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.

• Site Survey or Monitor mode: In this mode, specified Cisco APs 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 time stamp, 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 is displayed.

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.
