Cisco Catalyst 9120AXI-E Wireless Access Point, Wi-Fi 6, 4x4 Dual 5GHz Radio, CleanAir with Cisco RF ASIC, MU-MIMO, PoE, Internal antenna (C9120AXI-E)

Product Information

To use Smart Licensing, you must first set up a Smart Account on Cisco Software Central ( software.cisco.com). Cisco Embedded Wireless Controller on Catalyst Access Points: Indoor environments, with internal antennas. A power savings mode called Target Wake Time (TWT) allows the client to stay asleep and to wake up only at pre-scheduled (target) times to exchange data with the AP. This offers significant energy savings for battery-operated devices, up to 3x to 4x compared to 802.11n (WiFi 4) and 802.11ac (WiFi 5).

Optimize the performance of your networks to get the most from your technology investments. Accelerate your business outcomes with expert guidance from Cisco technical and professional services. I wanted to upgrade my WiFi at home from two 2802i running on Mobility Express to 802.1AX AP's running on eWLC. As availabiltity for 9120's is quite poor here in Germany I bought two 9115AXI-E and converted them to eWLC. The Cisco Catalyst 9800 Series Wireless Controllers are feature rich and enterprise ready to power your business-critical operations and transform end-customer experiences: Cisco Catalyst 9162I Access Point, Wi-Fi 6E, Internal Antennas, 2x2+2x2+2x2 MIMO, 2.5G mGig with Meraki. FRA and Dynamic Channel Assignment (DCA) will enforce many configuration requirements when operating as dual 5-GHz Macro/Micro:

Secure infrastructure

Spatial Reuse (also known as Basic Service Set (BSS) coloring) which allows APs and their clients to differentiate between BSSs, thus permitting more simultaneous transmissions. To overcome the visibility limitations inherent to standard Wi-Fi chipsets, Cisco has created an integrated solution with patented chips and software that has been specifically designed to analyze and classify all RF activity. (More than 25 patents have been issued for this technology to date.)

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. Supporting four spatial streams, Multiuser Multiple Input, Multiple Output (MU-MIMO) enables access points to split spatial streams between client devices, to maximize throughput.Cisco Aironet patch antenna, wall/pole mount, Peak Gain 6 dBi at 2.4 GHz and 6 dBi at 5 GHz, 4-port DART connector Detailed Channels and Maximum Power Settings for Cisco Catalyst 9120AXE Indoor Access Points, Release 17.6.1 03-Aug-2021 (XLSX - 26 MB) To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to https://www.cisco.com/go/DirTAC. WiFi 6, with better coordination of transit time to and from devices, will also bring about a reduction in latency and a greater reliability allowing for hundreds of devices per access point. This allows for IoT devices to be reliably deployed at scale. And an overall improved user experience will be seen as well, as 802.11ax (WiFi 6) will improve device battery life of devices such as smartphones, tablets and IoT when compared to prior standards. Secure infrastructure

Like Scott said -E is the regulatory domain and that applies to all European countries - you won't see the -E change to anything else. Provides uplink speeds of 2.5 Gbps, in addition to 100 Mbps and 1 Gbps. All speeds are supported on Category 5e cabling for an industry first, as well as 10GBASE-T (IEEE 802.3bz) cabling. When using the 2.4-GHz frequency, the same 1-, 6-, and 11-channel scheme is used as is the 5-GHz channel scheme. Avoid putting all of the APs on the same channel, and reuse channels as you can.The custom solution starts with the Cisco SAgE hardware core, which has been integrated directly into the Cisco RF ASIC custom silicon. The SAgE core handles very compute-intensive operations, such as high-resolution Fast Fourier Transform (FFT) and pulse detection operations. (A pulse is a burst of RF energy in frequency and time.) The SAgE core has a highly granular spectral resolution of 78.125 kHz (4x better than the nearest competitive solution and 64x better than most chipsets).

Cisco Secure Boot technology anchors the boot sequence chain of trust to immutable hardware, mitigating threats against a system’s foundational state and the software that is to be loaded, regardless of a user’s privilege level. It provides layered protection against the persistence of illicitly modified firmware. Application Hosting on Catalyst 9100 Access: Application Hosting on Catalyst 9100 Access Points helps future-proof and simplify IoT deployments by eliminating the need to install and manage overlay networks. Utilizing 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.

Apple features

When installing any Wi-Fi equipment inside the elevator cars or shafts, local regulations need to be followed, as many times such installations are prohibited either for safety reasons or because the building owner or local fire department may prohibit them. Also, it is dangerous, and only elevator repair persons or contractors experienced with this kind of work should be in those areas. When the need for external antennas is a requirement, again position/use the Catalyst 9120e model.
