Installations Using a Common or Distributed Antenna System (DAS)

Due to the dual-band nature of the antenna system on the AP 2600 and AP 3600, along with key features such as ClientLink 2.0 beamforming, it is not recommended for deployments on Distributed Antenna Systems commonly referred to as DAS.

Customers wishing to integrate a Wi-Fi over DAS solution should understand that Cisco does not certify, endorse or provide RF support for Wi-Fi deployments over ANY Distributed Antenna System.

The DAS vendor and/or systems integrator is solely responsible for the support of the DAS products and for providing adequate RF coverage and supporting any RF-related issues. This support includes, but is not exclusive to location accuracy, RF coverage, roaming issues related to RF, multipath issues, and scalability.

Additionally, the DAS vendor and/or systems integrator is responsible for understanding that the deployed DAS system meets the requirements of all of the customer's Wi-Fi devices and applications over the DAS system; this statement includes, but is not exclusive to, all Voice over WLAN (VoWLAN) and medical devices.

While Cisco Technical Assistance Center (TAC) and Cisco field teams do not provide support for RF issues that arise in a Cisco WLAN used over a DAS, they will provide support for non-RF related issues in Cisco products per the customer's support agreement with Cisco Systems.

Installations Inside and Around Elevators

Elevator coverage can sometimes be accomplished by placing APs in the near field of the elevator, typically on each floor near the elevator door. Since elevators often have metal doors and the shafts are often concrete or contain other materials that degrade Wi-Fi coverage, it is important to check the coverage inside the elevator. While such coverage can be challenging it is often do-able, especially if the elevator is only a few floors.

High rise elevators are more challenging since roaming issues are problematic as the client is cycling through a large number of APs rather quickly. Some companies that do in-elevator advertising have put a patch antenna on the floor inside the shaft and a patch antenna on the bottom of the elevator car, while other companies have used leaky coaxial cable running on the side of the shaft.

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 same. Also, it is dangerous and only elevator repair persons or contractors experienced with this kind of work should be in those areas.

AIRRM3000ACAK9 specifications

Cisco Systems has long been a leader in networking solutions, and one of its standout offerings in the wireless access point market is the AIR-RM3000-AK9 model. This device is designed to provide high-performance and reliable wireless connectivity for a wide range of applications, making it an ideal choice for organizations that demand robust networking capabilities.

One of the main features of the AIR-RM3000-AK9 is its dual-band operation, which allows it to operate on both the 2.4 GHz and 5 GHz frequency bands. This dual-band capability enables the access point to support a greater number of devices and deliver higher data throughput, thereby enhancing the overall user experience. The access point can automatically select the best band, ensuring optimal performance based on network conditions and user requirements.

The device also supports the latest Wi-Fi 5 (802.11ac) standard, delivering impressive wireless speeds and improved capacity compared to previous generations. With Multi-User Multiple Input Multiple Output (MU-MIMO) technology, the AIR-RM3000-AK9 can communicate with multiple devices simultaneously. This feature is particularly advantageous in crowded environments, as it helps to reduce latency and increase overall network efficiency.

Security is another critical aspect of the AIR-RM3000-AK9. It offers advanced security protocols such as WPA2 and WPA3, ensuring that data remains protected as it traverses the wireless medium. Additionally, with Cisco's identity and access services, organizations can manage user access and maintain compliance with security policies.

The access point is also designed for easy deployment and management. With support for Cisco DNA Center, network administrators can leverage a centralized platform for monitoring, troubleshooting, and optimizing network performance. This capability is essential for reducing operational costs and improving overall network reliability.

Moreover, the AIR-RM3000-AK9 features advanced Quality of Service (QoS) capabilities to prioritize traffic, ensuring that critical applications receive the bandwidth they need for seamless operation. This feature is particularly beneficial for organizations that rely on real-time applications such as video conferencing and VoIP.

In summary, Cisco Systems AIR-RM3000-AK9 access point stands out due to its dual-band operation, support for Wi-Fi 5, MU-MIMO technology, robust security features, and ease of management. These characteristics make it an excellent choice for businesses seeking to enhance their wireless networking capabilities while ensuring high performance and security.
