Product Overview

Juniper built the first AI-driven wireless platform, designed specifically for the Smart Device Era. The Juniper AI-Driven Network makes Wi-Fi predictable, reliable, and measurable by providing unprecedented visibility into the user experience and replacing time-consuming manual IT tasks with proactive automation. In addition, Juniper is the first vendor to bring enterprise-grade Wi-Fi, Bluetooth LE, and IoT together to deliver personalized, location-based wireless services without requiring battery-powered beacons.



Juniper AI-Driven Network Network Components

Marvis Virtual Assistant

Patent-pending machine learning algorithms adapt in real-time to optimize the wireless user experience. In addition, Marvis uses AI to proactively automate IT operations, provide real-time alerts, and predict problems before they arise.


The Juniper Mist™ Cloud Architecture

All wireless deployment, setup, operations, and insight are handled by Juniper Mist cloud services, which were designed to provide unprecedented visibility and control at Web scale. A microservices architecture provides maximum agility when rolling out new features and services.


Juniper Access Point Family

The Juniper enterprise-grade access point family consists of:

  • AP21, AP41, and AP61 Series, which support 802.11ac Wave 2, Bluetooth LE, and IoT
  • AP12, AP32, AP33, AP43, and AP63 Series, which support 802.11ax (Wi-Fi 6), Bluetooth LE, and IoT
  • BT11, which supports Bluetooth LE

These access points are all built on a real-time microservices platform and are managed by the Juniper Mist cloud.

AP21 Features

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.


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.


High-Accuracy Indoor Location

The AP21 works with the Juniper Mist cloud to provide high-accuracy, enterprise-grade Bluetooth LE location services using virtual beacons

Unprecedented Insight and Action

 A dedicated dual-band radio collects data for Juniper’s patent- pending 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).


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.


Dynamic Packet Capture

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.


Automatic RF optimization

The AP21’s dual-band scanning mode continuously scans the airspace for threats and interference. This ensures optimal performance under what could otherwise be challenging RF conditions. The AP21’s dual-band radios scan the airspace for threats and interference.


The AP21 collects data for the Juniper Mist cloud to enforce service-level expectations (SLEs) and to offer Premium Services.
