The Juniper AP21 is a high-performance access point that supports 802.11ac Wave 2 Wi-Fi and patented virtual Bluetooth LE. The AP21 works in conjunction with the Juniper Mist cloud architecture driven by Mist AI to collect and analyze metadata in near real-time from all wireless clients. This enables rapid problem detection and root cause identification with proactive correction e.g. for applications such as self-driving networks.

In addition, the AP21 has a dynamic vBLE 16-element antenna array for the industry’s most accurate and scalable location services, including User Engagement, Asset Visibility, and Contact Tracing applications. This is achieved without the need for battery-powered BLE beacons and manual calibration.

Juniper AI-Driven Network

Juniper brings true innovation to the wireless space with the world’s first AI-driven wireless LAN (WLAN).

The Juniper AI-Driven Enterprise makes Wi-Fi predictable, reliable, and measurable with unprecedented visibility into the user experience through customizable service level expectation (SLE) metrics. Time-consuming manual IT tasks are replaced with AI-driven proactive automation and self-healing, lowering Wi-Fi operational costs and saving substantial time and money.

All operations are managed via our open and programmable microservices architecture, which delivers maximum scalability and performance while also bringing DevOps agility to wireless networking and location services.

The Juniper Mist Cloud Architecture

Juniper’s Mist AI leverages a cloud-native microservices architecture that delivers unparalleled agility, scale, and resiliency to your network. An AI engine lowers OpEx and delivers insights by using data science to analyze large amounts of rich metadata collected from Juniper Access Points.

Juniper Mist Edge

Juniper Mist Edge is an on-premises appliance that runs a tunnel termination service. Juniper APs offer a flexible data plane. Traffic can be broken out locally, or tunneled to Juniper Mist Edge. There are many use cases the Juniper Mist Edge solves, including seamless mobility in large campus environments, tunneling of guest traffic to a DMZ, IoT segmentation, and teleworker.


High Performance Wi-Fi

The AP21 delivers high-performance wireless access with two 802.11ac Wave 2 radios that deliver up to 867 Mbps in the 5GHz band and up to 400 Mbps in the 2.4GHz band.

Unprecedented Insight and Action

A dedicated dual-band radio collects data for Juniper’s patentpending Proactive Analytics and Correlation Engine (PACE), which leverages machine learning to analyze user experiences, correlate problems, and automatically detect the root cause of problems. These metrics are used to monitor service-level expectations (SLEs) and provide proactive recommendations to ensure problems don’t occur (or are fixed as quickly as possible when they do).

Automatic RF optimization

Constantly monitor services running on the AP21 and send alerts whenever a service behaves abnormally. Dynamic debugging relieves IT of having to worry about an AP going offline or any services running on it becoming unavailable.

Dynamic Packet Capture

The Juniper Mist platform automatically captures packets and streams them to the cloud when major issues are detected. This saves IT time and effort and eliminates the need for truck rolls with sniffers.

Marvis Virtual Conversational Assistant

Marvis is a natural language processing (NLP)-based assistant with a Conversational Interface to understand user intent and goals, simplifying troubleshooting and the collection of network insights. It uses AI and data science to proactively identify issues, determine the root causes and scope of impact, and gain insights into your network and user experiences. It eliminates the need to manually hunt through endless dashboards and CLI commands.

Effortless, Cloud-Based Setup and Updates

The AP21 automatically connects to the Mist cloud, downloads its configuration, and joins the appropriate network. Firmware updates are retrieved and installed automatically, ensuring that the network is always up to date with new features, bug fixes, and security updates.

Premium Analytics

Juniper Mist’s Wireless Assurance, User Engagement, and Asset Visibility service includes a base analytics capability for analyzing up to 30 days of data, from which you can extract network insights across your enterprise. For enterprises that need to extend the data timeline past 30 days or access third-party* solutions for customized reporting, the Juniper Mist Premium Analytics service is available as an additional subscription.

Dynamic Debugging

Constantly monitor services running on the AP21 and send alerts whenever a service behaves abnormally. Dynamic debugging relieves IT of having to worry about an AP going offline or any services running on it becoming unavailable.

High-Accuracy Indoor Location

The AP21 has a 16-element Virtual Bluetooth LE (vBLE) antenna array controlled from the Juniper Mist cloud. Passive antennas enhance the power of a single transmitter and produce directional beams to accurately detect distance and location with 1 to 3 meter accuracy. With Juniper’s patented vBLE technology, you can deploy an unlimited number of virtual beacons in your physical environment without requiring battery-powered BLE beacons.

Patented VBLE Technology

In addition to the industry-leading Wi-Fi technology at the heart of the AP43 access point, our second-generation, patented, and dynamic, 16-element virtual Bluetooth LE (vBLE) antenna array combines with machine learning to eliminate the need for battery-powered beacons. This maximizes scalability and optimizes your deployment investment in location-based services. vBLE enables businesses to provide rich location-based experiences that are engaging, accurate, real-time, and scalable.
