Indoor Access Point

Enterprise-Grade, High-Performance, Easy Installation

Product Overview

The AP3912 is a feature rich 802.11ac Wave 2 and 802.11abgn indoor access

point that delivers enterprise-grade performance and security for small

service areas such as residence halls, patient rooms, or conference rooms.

Although simple to install, the AP3912 oers a range of connectivity

options including three policy controllable wired LAN ports, 2.4/5G , and

a wired pass-through port. It is also future proofed, with an integrated

BTLE/802.15.4 (support for ZigBee, Thread and other higher level

protocols) radio for extended connectivity to Internet of Things (IoT)

sensors and devices.

The energy ecient AP3912 uses 802.3af Power over Ethernet (PoE) in

normal operating mode. For deployments that require powering a wired

device upstream such as an IPTV or VOIP phone, the AP3912 can optionally

provide 802.3af power to a wired device when powered via 802.3at PoE+

by a downstream switch.

The AP3912 is built using the latest in technology, including 802.11ac

Wave 2, dynamic radio management, spectrum analysis with interference

classiﬁcation, beamforming, multi-user MIMO, self-forming and self-healing

meshing, security, role-based authentication, authorization, and access

control to ensure consistent and secure connectivity to users and sensors.

The 2x2:2 platform is capable of delivering up to 1.2 Gbps over-the-air-

performance and up to 50,000 packets per second on the wired port with a

unique ﬂow-based architecture that provides consistent performance even

when enforcing extensive Layer 7 (application-based) service requirements.

Highlights

Business Alignment

• Extends secure connectivity to

Internet of Things (IoT) sensors for

Smart Buildings while reducing risks

from weak or insecure sensors

• Enforces role-based grouping of

users, devices, and applications to

deliver priority, QoS, and security in

accordance with business needs for

both wired and wireless devices

• Support for demanding voice/video/

data applications to enhance mobile

worker productivity and convenience

• Seamless roaming across an entire

multi-subnet campus without the

need for cumbersome client software

• Integrated management, security,

and QoS features reduce operating

cost and ensure a consistent user

experience regardless of location

Operational Eciency

• Reuses existing cabling and

Power over Ethernet (PoE)

infrastructure, reducing costs

while improving service

• Centralized visibility and control

accelerates problem resolution,

optimize network utilization, and

automate management

• Adaptive architecture reduces

complexity and optimizes

information ﬂow for each application

• Dynamic Radio Management when

used for planning and monitoring

ensures optimal spectrum coverage

resulting in the best end-user quality

of experience

• Flexible Client Access optimizes

throughput for 802.11ac/n clients in

today’s mixed ac, n, and a/b/g client

environments

Flexible Management Options

• On premise, with hardware or virtual

ExtremeWireless Appliance

• ExtremeCloud™ Cloud-Managed

Networking Platform (future)
