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

The 9120AX series device includes a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves (radio frequency electromagnetic fields) recommended by international guidelines. The guidelines were developed by an independent scientific organization (ICNIRP) and include a substantial safety margin designed to ensure the safety of all persons, regardless of age and health. This Cisco Catalyst 9120AXI Access Point supports Software-Defined Access, Cisco’s leading enterprise architecture. Working together, this and Cisco DNA offer such features as: Cisco offers the industry’s broadest selection of antennas, delivering optimal coverage for a variety of deployment scenarios

External antennas on the 9120AXE and 9120AXP AP models (C9120AXE-x, C9120AXE-EWC-x, C9120AXP-x and C9120AXP-EWC-x).Cet appareil est conforme aux directives internationales en matière d'exposition aux fréquences radioélectriques Always try to mount the AP as close to the users as possible for best performance. Be aware of the environment (for example, hospitals have metal doors, coverage can change when the doors close, old buildings can have metal grid work in the plaster or asbestos). Avoid mounting the AP or antennas near metal objects, as doing so can change the coverage area affecting clients.

The Cisco Catalyst 9115 Series with Wi-Fi 6is the next generation of enterprise access points. They are resilient, secure, and intelligent. Operation in the band 5150-5250 MHz is only for indoor use to reduce the potential for harmful interference to co-channel mobile satellite systems. Cisco’s technical and professional services provide the expertise, smart tools, and proven processes that reduce risk and downtime.

Secure infrastructure

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. Cisco Catalyst 9162I Access Point, Wi-Fi 6E, Internal Antennas, 2x2+2x2+2x2 MIMO, 2.5G mGig with Reg-X. Supporting four spatial streams, MU-MIMO enables access points to split spatial streams between client devices, to maximize throughput.

FCC Bulletin 56: Questions and Answers about Biological Effects and Potential Hazards of Radio Frequency Electromagnetic Fields The 9115 Wi-Fi 6 access points are available with a built-in controller. The Cisco Embedded Wireless Controller on Catalyst 9100 Access Points provides an easy-to-deploy and manage option that does not require a physical appliance. The control resides on the access point, so there is no added footprint or complexity. And because it uses Cisco Catalyst 9800 Series code, it’s easy to migrate your network as your needs grow. For more details refer to EWC The controller collects all join-related information for each access point that sends a CAPWAP discovery request to the controller. Collection begins with the first discovery message received from the access point and ends with the last configuration payload sent from the controller to the access point. For detailed information and guidelines for configuring and deploying your access point in a wireless network, see the following documentation:Macro/Macro – Dual independent 5-GHz cells, doubling the coverage of a single traditional dual-band AP. Macro/Macro is only supported on 9120e (as external antennas are used to accomplish this). The IEEE 802.11ax emerging 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 IoT. Wi-Fi 6 is designed to use both the 2.4-GHz and 5-GHz bands, unlike the 802.11ac standard. 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.) Cisco does not represent, warrant, or guarantee that it is complete, accurate, or up to date.

MU‑MIMO technology: Suppo https://www.cisco.com/en/US/prod/collateral/wireless/ps9391/ps9393/ps9394/prod_white_paper0900aecd807395a9_ns736_Networking_Solutions_White_Paper.html The Catalyst 9124AXD access point has four internal directional dual-band (2.4- and 5-GHz) antennas that reside under a sealed radome and cannot be accessed. Note: These are all dual-band, dual-resonant antennas. Do not use single-band antennas on this product unless you choose to separate the AP into dedicated antennas (for example, dual 5 GHz or 5 GHz on top and 2.4 GHz on the DART). Single-band antennas need to be of the same gain and type as the antennas listed above and may not exceed 6 dBi on the 9120e Series. The RF ASIC provides the AP with an advanced and comprehensive interference analysis, detection, and mitigation system. Essentially, the SAgE core handles a base level of spectrum analysis operations that are so processing intensive that they can be prohibitive to handle in real-time software or by the serving radios.
