The Cisco Aironet

™

4800 Wi-Fi access point is highly versatile and delivers the most functionality of

any access point in the industry.

Product overview

The Cisco Aironet 4800 Access Point is packed with an abundance of features that offer users a better experience, top-notch

security, and high-speed connectivity. The Aironet

4800 makes troubleshooting easier and enhances the context shown in

Cisco DNA Assurance.

The access point’s functionality is spread out over four internal radios, so these features run simultaneously over your network.

The Aironet 4800 expands the current rich capabilities of our current Aironet portfolio (with features such as built-in Flexible

Radio Assignment, Hyperlocation, and Bluetooth Low Energy [BLE]) and adds a fourth internal radio to provide rich

performance and location and security analytics. With more radios embedded in the access point, your wireless network

achieves higher security and data analysis without degrading performance—you’ll never again have to trade security for

network performance.

What does this mean?

For starters, having a fourth radio allows the BLE and security monitoring functions to run on their own individual radios, while

the other two radios tend to the business of providing exceptional Wi-Fi. This level of visibility provides IT more powerful

capabilities to help ensure the user experience for productivity and engagement.

based on Cisco technologies. Using new features in iOS 10, in combination with the latest software and

hardware from Cisco, businesses can now more effectively use their network infrastructure to deliver an

enhanced user experience across all business applications.

At the center of the collaboration is a unique handshake between the Cisco WLAN and Apple devices. This

handshake enables the Cisco WLAN to provide an optimal Wi-Fi roaming experience to Apple devices.

Additionally, the Cisco WLAN trusts Apple devices and gives priority treatment for business-critical applications

specified by the Apple device.

After First Customer Shipment (FCS).

The capabilities of the new Aironet 4800 include features that the competition can’t measure up to. From the built-in

Intelligent Capture that provides enhanced issue detection and root cause analysis to on-demand, real-time troubleshooting to

in-service access point monitoring with packet capture, the Aironet 4800 protects the network like no other. Want proof?

Intelligent Capture is two to three times faster than the competition in client location tracking and client onboarding and is

three to five times faster when it comes to client RF stats.

An integrated radio for Hyperlocation provides more granular data by enabling device monitoring and tracking to within 3

meters—the best in the industry. With such pinpoint accuracy, you can say goodbye to equipment that mysteriously disappears

from the office. How? Hyperlocation allows for historical monitoring of asset location. If a tagged device disappears, you can go

back and figure out when it left the area.

Hyperlocation can also help your employees and guests find their way through your building with the app-enabled indoor

wayfinding and navigation features. These features enable a mobile client to query its own location for indoor wayfinding. In

addition, an app can be created that will provide a Point Of Information (POI) and detect when the user is present.

Another great use for Hyperlocation is location analytics. You can get information on devices, dwell time, and path analytics,

among other data, for any device that connects to your network. By combing this data with Operation Insights, you can make

better business decisions while maintaining an always-on, always-available user experience. For instance, you can determine

that one part of the office is never being used at certain times, and take advantage of this knowledge by making sure the lights

are off, thus reducing energy use and saving money.

Before the Hyperlocation feature was embedded in the Aironet 4800, there was no way get this feature on a Cisco 802.11ac

Wave 2 access point.

With a radio dedicated solely to security, the Aironet 4800 is a sentry designed to stop any rogue agents attempting to gain

access to your network, 24 hours a day, 7 days a week. This dedicated radio constantly monitors the wireless network, looking

for anything that can cause a threat. And with the radio’s ability to pinpoint causes for concern less than 3 meters away, you

know you’re getting security that finds the little things before they can grow into big problems. The Aironet 4800 protects the

network while predicting and responding to issues and threats faster.

The Aironet 4800 also offers real-time troubleshooting. It does this by sniffing and decrypting live traffic using one of the

access point’s four radios. Similarly, due to the device’s live monitoring of critical radio statistics, such as MU-MIMO, data rates,

channel utilization, and others, it’s able to quickly detect many types of wireless security threats. These capabilities, together

with monitoring of critical assets such as Received Signal Strength Indication (RSSI), packet retry, and more, are examples of

how the Aironet 4800 access point focuses on the health of your network.

The Aironet 4800 does more than guard the network. It also detects issues and the causes of poor client performance. Solving

roaming issues and finding root causes for poorly performing clients such as “sticky clients” are handled by tracking pre- and

post-associated radio behavior via client scanning.

When the Aironet 4800 is paired with Cisco DNA Center with Assurance, a whole host of features open up for the network. For

example, once an issue is discovered, the network administrator is able to go back in time (up to 7 days) and investigate the

root cause of the problem. From there, suggested actions are offered to fix the issue.

802.11ac Wave 2 and beyond

The Aironet 4800 extends 802.11ac speed and features to a new generation of smartphones, tablets, and high-performance

laptops, providing a greater end-user experience. Whether your project involves wholesale changes to your current wireless

network or upgrading your legacy Wi-Fi deployments (802.11a/b/g/n/ac Wave 1 deployments), the Aironet 4800 can handle the

job.

The Aironet 4800 supports 802.11ac Wave 2, providing a theoretical connection rate of up to 5.2 Gbps—that’s roughly four

times the rate offered by today’s high-end 802.11ac access points. The boost helps you stay ahead of the performance and

bandwidth expectations of today’s mobile worker, who usually uses multiple Wi-Fi devices instead of just one. As such, users

are adding proportionally larger traffic loads to the wireless LAN, which has outpaced Ethernet as the default enterprise access

network.

Cisco DNA support

Pairing the Aironet 4800 access points with the Cisco Digital Network Architecture (Cisco DNA) allows for a total network

transformation. Cisco DNA allows you to truly understand your network with real-time analytics, quickly detect and contain

security threats, and easily provide networkwide consistency through automation and virtualization. By decoupling network

functions from the hardware, you can build and manage your entire wired and wireless network from a single user interface.

Working together, the Aironet 4800 and Cisco DNA offer such features as:

●

Flexible Radio Assignment

●

Cisco Connected Mobile Experiences

●

Cisco High Density Experience

●

Fast Lane

●

Cisco Identity Services Engine

●

And much more

The result? Your network stays relevant, becomes digital ready, and is the lifeblood of your organization.
