AP21 Access Point Overview

The Juniper® AP21 High Performance Access Point is a Wi-Fi 5 indoor access point (AP) that supports 802.11ac Wave 2, Bluetooth Low Energy (BLE), and Internet of Things (IoT). The AP21 leverages the Mist AI to collect and analyze real-time data from wireless clients. Mist uses this data to identify a network problem and its root cause and also provide proactive recommendations for resolution.

The AP21 has two IEEE 802.11ac Wave 2 radios, which deliver up to 2x2 multiple input, multiple output (MIMO) with two spatial streams in each of the 2.4-GHz and 5-GHz radio bands. The AP21 is backward compatible with the 802.11a, 802.11b, 802.11g, and 802.11n wireless standards.

The AP21 has a dynamic virtual Bluetooth Low Energy (vBLE) antenna array that the Juniper Mist cloud controls. The AP21 leverages the Mist AI to provide highly accurate Bluetooth LE location services using virtual beacons. Virtual beacons eliminate the need for physical beacons, resulting in time and cost savings.

The AP21 provides maximum data rates of 867 Mbps in the 5-GHz band and 400 Mbps in the 2.4-GHz band.

AP21 Access Point Models

The AP21 is available in two models:

  • AP21-US (United States only)

  • AP21-WW (Outside of United States)


Juniper products are manufactured in accordance with electrical and environmental regulations specific to certain regions and countries. Customers are responsible for ensuring that any regional or country-specific SKUs are used only in the specified authorized area. Failure to do so may void the warranty of Juniper products.

Benefits of AP21 Access Points

  • Simple and quick deployment—You can deploy the AP with minimal manual intervention. The AP automatically connects to the Juniper Mist cloud after powering on, downloads its configuration, and connects to the appropriate network. Automatic firmware upgrades ensure that the AP runs the latest firmware version.

  • Proactive troubleshooting—The AI-driven Marvis® Virtual Network Assistant leverages the Mist AI to identify issues proactively and provide recommendations to fix issues. Marvis can identify issues such as offline APs and APs with insufficient capacities and coverage issues.

  • Location precision and accuracy—The directional vBLE antenna array provides precise locations and accurate location services.
