The Cisco Aironet 1840 Series access points represent a significant milestone in enterprise-grade wireless networking, specifically engineered to address the growing demands of modern, high-density environments. As businesses increasingly rely on mobile devices and bandwidth-intensive applications, the need for reliable, high-speed connectivity has never been more critical. This series is designed to provide a robust foundation for organizations looking to transition toward 802.11ac Wave 2 standards without compromising on performance or budget. By integrating advanced radio technology with intelligent software features, these access points ensure that users experience seamless connectivity, whether they are in a crowded office, a classroom, or a public venue.

At its core, the 1840 Series is built to simplify the deployment and management of wireless networks while maintaining the high security and reliability standards that Cisco is known for. The architecture focuses on optimizing the user experience by intelligently managing traffic and ensuring that critical applications receive the necessary bandwidth. This approach not only enhances productivity but also reduces the operational burden on IT departments. By leveraging the power of the Cisco Unified Wireless Network, the 1840 Series allows for centralized control, making it an ideal choice for small to medium-sized enterprises that require enterprise-class features in a compact and efficient form factor.

Product overview

The Cisco Aironet 1840 Series consists of several models, primarily the AIR-AP1840I, which is designed for indoor environments where aesthetics and performance must coexist. This access point utilizes 4x4 MU-MIMO technology with three spatial streams, allowing it to handle multiple client connections simultaneously. This capability is essential for environments where many devices are active at the same time, as it prevents bottlenecks and ensures that each device receives a fair share of the network resources. The hardware is encased in a sleek, low-profile design that blends into various professional settings, ensuring that the technology remains unobtrusive while delivering powerful wireless coverage.

In addition to the standard indoor model, the series is designed to work seamlessly with Cisco’s broader ecosystem, including the Mobility Express solution. This is particularly beneficial for organizations that may not have a dedicated hardware wireless controller on-site. The Mobility Express feature allows the access point to act as a virtual controller, simplifying the setup process and reducing the total cost of ownership. Furthermore, the 1840 Series supports advanced radio resource management, which automatically adjusts power levels and channel assignments to mitigate interference and maximize coverage. This level of automation is a game-changer for IT teams who need to maintain high network availability with limited manual intervention.

The series also emphasizes security and scalability, providing robust protection against unauthorized access and potential threats. By incorporating Cisco’s CleanAir technology, the 1840 Series can detect and mitigate interference from non-Wi-Fi sources, such as microwave ovens or Bluetooth devices, which often plague wireless performance in dense areas. This proactive approach to network health ensures that the wireless environment remains stable and secure. Whether an organization is looking to upgrade its existing infrastructure or build a new network from the ground up, the 1840 Series offers a versatile and future-proof solution that adapts to the evolving needs of the digital workplace.

Cisco Aironet 1840 Series Access Point

Ideal for small and medium-sized networks, the Cisco Aironet 1840 Series delivers industry-leading performance for enterprise and service provider markets via enterprise-class 4x4 MU-MIMO, four-spatial-stream access points that support the Institute of Electrical and Electronic Engineers (IEEE) 802.11ac Wave 2 standard. Integrated BLE radio enables location-based use cases such as wayfinding and asset tracking. The 1840 Series t extends support to a new generation of Wi-Fi clients, such as smartphones, tablets, and high-performance laptops that have integrated 802.11ac Wave 1 or Wave 2 support.

With the 1840 Series, you can secure remote workers or the micro-office. Any Cisco Aironet or Catalyst access point can function as an OfficeExtend Access Point (OEAP). With an OEAP, an employee at home or in a temporary micro-office will have access to the corporate SSID and the corporate network without the need to set up a VPN or have any advanced technical know-how.

Cisco User Defined Network, a feature available in Cisco DNA Center, allows IT to give end users control of their very own wireless network partition on a shared network. End users can then remotely and securely deploy their devices on this network. Perfect for university dormitories or extended hospital stays, Cisco User Defined Network grants both device security and control, allowing each user to choose who can connect to their network. (Available second half of calendar year 2020)

The Wi-Fi 6 readiness dashboard is a new dashboard in the Assurance menu of Cisco DNA Center. It will look through the inventory of all devices on the network and verify device, software, and client compatibility with the new Wi-Fi 6 standard. After upgrading, advanced wireless analytics will indicate performance and capacity gains as a result of the Wi-Fi 6 deployment. This is an incredible tool that will help your team define where and how the wireless network should be upgraded. It will also give you insights into the access point distribution by protocol (802.11 ac/n/abg), wireless airtime efficiency by protocol, and granular performance metrics.

Licensing

In order to connect any access points to the controller, Cisco DNA software subscriptions are required. To be entitled to connect to Cisco Catalyst 9800 Series Wireless Controller, the access point requires a Cisco DNA subscription license.

Figure 3.

Determining license requirements for access points connecting to Cisco Catalyst 9800 Series Wireless Controllers

The access points connecting to a Cisco Catalyst 9800 Series controller have new and simplified software subscription packages.

They can support both tiers of Cisco DNA software: Cisco DNA Essentials and Cisco DNA Advantage.

Cisco DNA software subscriptions provide Cisco innovations on the access point. They also include perpetual Network Essentials and Network Advantage licensing options, which cover wireless fundamentals such as 802.1X authentication, Quality of Service (QoS), and Plug and Play (PnP); telemetry and visibility, and Single-Sign-On (SSO), as well as security controls.

Cisco DNA subscription software has to be purchased for a 3-, 5-, or 7-year subscription term. If not renewed by the end of the term, Cisco DNA features will expire, whereas Network Essentials and Network Advantage features will remain.

For the full feature list of Cisco DNA Software, including the perpetual Network Essentials and Network advantage, please see the feature matrix:

Two modes of licensing are available

● Smart Licensing (SL) simplifies and adds flexibility to licensing. It is:

● Simple: Procure, deploy, and manage licenses easily. Devices self-register, removing the need for Product Activation Keys (PAKs).

● Flexible: Pool license entitlements in a single account. Move licenses freely through the network, wherever you need them.

● Smart: Manage your license deployments with real-time visibility into ownership and consumption.

● Specific License Reservation (SLR) is a feature used in highly secure networks. It provides a method for customers to deploy a software license on a device (product instance) without communicating usage information to Cisco. There is no communication with Cisco or a satellite. The licenses are reserved for every controller. It is node-based licensing.

Four levels of license are supported on the Cisco Catalyst 9800 Series Wireless Controllers. The controllers can be configured to function at any one of the four levels

● Cisco DNA Essentials: At this level the Cisco DNA Essentials feature set will be supported.

● Cisco DNA Advantage: At this level the Cisco DNA Advantage feature set will be supported.

● NE: At this level the Network Essentials feature set will be supported.

● NA: At this level the Network Advantage feature set will be supported.

For customers who purchase Cisco DNA Essentials, Network Essentials will be supported and will continue to function even after term expiration. And for customers who purchase Cisco DNA Advantage, Network Advantage will be supported and will continue to function even after term expiration.

Initial bootup of the controller will be at the Cisco DNA Advantage level.
