AP41 Access Point Overview
IN THIS SECTION
AP41 Access Point Models | 3
Benets of AP41 Access Points | 4
The Juniper® AP41 High Performance Access Point is a Wi-Fi 5 indoor access point (AP) that leverages
the Mist AI to collect and analyze real-me data from wireless clients. Mist uses this data to idenfy a
network problem and its root cause and also provide proacve recommendaons for resoluon.
The AP41 has three IEEE 802.11ac radios, which deliver up to 4x4 mulple input, mulple output
(MIMO) with four spaal streams. Out of the three radios, one is dedicated for scanning. The AP uses
this radio for radio resource management (RRM) and wireless security. The AP41 can operate in either
mul-user or single-user mode. The AP41 is backward compable with the 802.11a, 802.11b, 802.11g,
and 802.11n wireless standards.
The AP41 has integrated IoT sensors and an interface port to control analog or digital devices. This
capability is useful in advanced locaon-based use cases, such as door locking and camera control.
The AP41 also has a 16-element virtual Bluetooth Low Energy (vBLE) antenna array to support asset
visibility use cases. The AP41 provides real-me network insights and asset locaon services without
the need for baery-powered BLE beacons and manual calibraon.
The AP41 provides maximum data rates of 1730 Mbps in the 5-GHz band and 800 Mbps in the 2.4-GHz
band.

NOTE: Juniper products are manufactured in accordance with electrical and environmental
regulaons specic to certain regions and countries. Customers are responsible for ensuring that
3

any regional or country-specic SKUs are used only in the specied authorized area. Failure to do
so may void the warranty of Juniper products.
Benets of AP41 Access Points
• Simple and quick deployment—You can deploy the AP with minimal manual intervenon. The AP
automacally connects to the Mist cloud aer it powers on, downloads its conguraon, and
connects to the appropriate network. Automac rmware upgrades ensure that the AP runs the
latest rmware version.
•Proacve troubleshoong—The AI-driven Marvis® Virtual Network Assistant leverages the Mist AI
to idenfy issues proacvely and provide recommendaons to x the issues. Marvis can idenfy
issues such as oine APs and APs with insucient capacies and coverage.
• High locaon accuracy—The internal vBLE antenna provides precise locaon accuracy within a range
of 1 to 3 meters.

Power Requirements for AP41
The AP41 requires 802.3at (PoE+) power, and it requests a maximum of 25.5W. Ensure to connect an
AP41 or AP41E to an 802.3at or PoE+ switch. The AP41 requests 19.5 W to provide wireless
funconality, without PoE out and USB port support. You can use any of the following opons to power
on an AP41:
• Power over Ethernet Plus (PoE+) from an Ethernet switch
We recommend that you use an Ethernet cable with a maximum length of 100 m to connect the
access point (AP) to the switch port.
If you use an Ethernet cable that is longer than 100 m by placing an Ethernet PoE+ extender in the
path, the AP might power up, but the Ethernet link does not transmit data across such a long cable.
You might see the status LED blink yellow twice. This LED behavior indicates that the AP is unable to
receive data from the switch.
• PoE injector
• 12 VDC power supply

Claim an AP Using a Web Browser | 12
Claim an AP Using the Mist AI Mobile App | 13
You need to claim an access point (AP) to be able to manage the AP from the Juniper Mist cloud. You'll
need a claim code or an acvaon code to claim an AP. You can claim an AP by using one of the
following methods:
• Mist AI Mobile App
• A Web browser
Obtain the Claim Code or Acvaon Code for an AP
You can claim either a single AP using a claim code or mulple APs using an acvaon code. You can use
any of these methods to claim an AP:
• To claim a single AP, use the claim/QR code located on the rear of the AP.
11

• To claim mulple APs, you'll need to use an acvaon code. When you purchase mulple APs, we
provide you with an acvaon code along with your PO informaon.
Claim an AP Using a Web Browser
You can onboard a single AP or mulple APs using a Web browser. If you're onboarding a single AP, use
the claim code or QR code located on the rear of the AP. If you're onboarding mulple APs, use the
acvaon code that is listed in your purchase order.
NOTE: You can simultaneously claim mulple APs and acvate the subscripons listed in the PO
using the acvaon code. See Acvate a Subscripon.
To claim an AP using a Web browser:
1. Log in to your account at hps://manage.mist.com/.
If you don't have an account, see Create a Mist Account and Organizaon for details about creang
one.
2. Go to Organizaon > Inventory > Access Points and click Claim APs.
3. Enter the acvaon code or claim code.
12

4. (Oponal) Select the site to which you want to assign the AP.
You can choose to assign the AP to a primary site (default) or any other site. If you want to assign the
AP to a site later, clear the Assigned claimed APs to site check box.
5. (Oponal) Select the Generate names for APs, with format: check box and enter a name format for
the AP.
You can use this opon only if you are assigning the AP to a site.
You can also choose to rename and assign an AP to a site aer you claim the AP.
6. Click Claim.
Review the informaon and close the window.
Claim an AP Using the Mist AI Mobile App
To onboard a single AP using the Mist AI mobile app from your mobile phone:
1. Download and install the Mist AI app from the Google Play Store or Apple App Store.
2. Open the Mist AI app and log in using your account credenals.
If you do not have an account, see Create a Mist Account and Organizaon for details about creang
one.
3. Select your organizaon.
4. Tap the site to which you want to assign the AP.
5. Ensure that the Access Points tab is selected and tap +.
6. Locate the QR code on the AP. The QR code is located on the rear panel of the AP.
7. Focus the camera on the QR code.
13

The app automacally claims the AP and adds it to your site. You'll see the new AP listed under the
Access Points tab.
8. Tap the AP to view its details.
You can perform various tasks from the AP details screen such as renaming the AP, seng it on a
oor plan, releasing an AP, or even adding a photo. Simply tap the opon and you can update the
details. To rename an AP, tap the AP name and enter a new name.
To place an AP on a oor plan, tap Place on map. You need to have a oor plan already set up in
Locaon > Live View in the Mist to use this opon. See Adding and Scaling a Floorplan.
Aer you place the AP on the oor plan, you'll see more details such as the posion of the AP and
the height at which the AP is mounted (default value that you can modify).
