MR42E

Dual-band, 802.11ac Wave 2 access point with

external antenna connectors for general-purpose

Wi-Fi and focused coverage

General purpose, cloud-managed 802.11ac wireless

The Cisco Meraki MR42E is a cloud-managed 3x3 MIMO 802.11ac

Wave 2 access point. Designed for general purpose deployments

in offices, schools, shops, and hotels, the MR42E provides

performance, security, and manageability. The MR42E provides

a maximum 1.9 Gbps frame rate with concurrent 802.11ac Wave 2

and 802.11n 3x3:3 MIMO radios, and security and spectrum visibility

via a third radio dedicated to 24x7 WIDS/WIPS and automated RF

optimization. An integrated Bluetooth low energy (BLE) radio delivers

Beacon functionality and BLE device scanning.

The MR42E supports a variety of smart, auto-detectable external

antenna that can deliver both focused, targeted coverage in

challenging RF scenarios as well as broader coverage in a variety of

environments, including those with very high ceilings. These antenna

include panel and panel downtilt omni-directionals, wide patch, and

narrow patch options.

The combination of cloud management, 802.11ac Wave 2, full-time

RF environment scanning, and an integrated Bluetooth technology

delivers the high throughput, reliability, and flexibility required by the

most demanding business applications like voice and high-definition

streaming video, both today and tomorrow.

MR42E and Meraki cloud management:

a powerful combination

Management of the MR42E is handled through the Meraki

dashboard, an intuitive browser-based interface that enables

rapid deployment across multiple sites without the need for time-

consuming training or costly certifications.

Since the MR42E is self-configuring and managed over the web,

it can be deployed at a remote location in a matter of minutes,

even without on-site IT staff. 24x7 monitoring via the Meraki cloud

delivers real-time alerts if the network encounters problems.

Remote diagnostic tools enable immediate troubleshooting so that

distributed networks can be managed with a minimum of hassle.

The MR42E’s firmware is automatically kept up to date via the

cloud. New features, bug fixes, and enhancements are delivered

seamlessly over the web. This means no manual software updates to

download or missing security patches to worry about.

Features

Aggregate data rate of up to 1.9 Gbps

A 5 GHz 3x3:3 802.11ac Wave 2 radio and a 2.4 GHz 3x3:3 802.11ac

radio offer a combined aggregate dual-band data rate of 1.9 Gbps.

Supports up to 1,300 Mbps in the 5 GHz band (with 3SS/VHT80

clients) and 600 Mbps in the 2.4 GHz band (with 3SS/VHT40 clients).

Technologies like transmit beamforming and enhanced receive

sensitivity allow the MR42E to support a higher client density than

typical enterprise-class access points, resulting in fewer required APs

for a given deployment.

Integrated enterprise security and guest access

The MR42E features integrated, easy-to-use security technologies to

provide secure connectivity for employees and guests alike.

Advanced security features such as AES hardware-based encryption

and WPA2-Enterprise authentication with 802.1X and Active Directory

integration provide wire-like security while still being easy to

configure. One-click guest isolation provides secure, Internet-only

access for visitors. Our policy firewall (Identity Policy Manager)

enables group or device-based, granular access policy control.

Meraki Teleworker VPN makes it easy to extend the corporate LAN

to remote sites, without requiring all clients and devices to have

client VPN software. PCI compliance reports check network settings

against PCI requirements to simplify secure retail deployments.

Dedicated third radio delivers 24x7 wireless security and

RF analytics

The MR42E’s sophisticated, dedicated dual-band third radio scans

the environment continuously, characterizing RF interference and

containing wireless threats like rogue access points. No more need

to choose between wireless security, advanced RF analysis, and

serving client data: a dedicated third radio means that all three occur

in real-time, without any impact to client traffic or AP throughput.

Application-aware traffic shaping

The MR42E includes an integrated Layer 7 packet inspection,

classification, and control engine, enabling you to set QoS policies

based on traffic type. Prioritize your mission critical applications,

while setting limits on recreational traffic, e.g., peer-to-peer and video

streaming.

Bluetooth low energy Beacon and scanning

An integrated Bluetooth low energy radio provides seamless

deployment of BLE Beacon functionality and effortless visibility of

BLE devices within range of the AP. The MR42E enables the next

generation of location-aware applications and engagement right out

of the box.

Voice and Video optimization

Industry standard QoS features are easy to configure like Wireless

Multi Media (WMM) Access Categories, 802.1p, and DSCP.

Automatic cloud-based RF optimization

The MR42E’s sophisticated, automated RF optimization means that

there is no need for the dedicated hardware and RF expertise

typically required to tune a wireless network. The real-time

fullspectrum RF analysis data collected by the dedicated third radio

is continuously fed back to the Meraki cloud. The Meraki cloud then

automatically tunes the MR42E’s channel selection, transmit power,

and client connection settings for optimal performance under the

most challenging RF conditions.

Low-profile, environmentally friendly design

Despite its robust feature set, the MR42E is packaged in a sleek,

low-profile enclosure that blends seamlessly into any environment.

Energy-saving components and intelligent power management

techniques deliver best-in-class energy efficient performance and

mean that pollution, material utilization, and your electric bill are kept

to a minimum.

Self-configuring, self-optimizing, self-healing

When plugged in, the MR42E automatically connects to the Meraki

cloud, downloads its configuration, and joins the appropriate

network. The MR42E then self-optimizes, determining the ideal

channel, transmit power, and client connection parameters. As

necessary, it will also self-heal, responding automatically to switch

failures and other errors.

Secure wireless environments using 24x7 Air Marshal

No longer choose between a wireless intrusion prevention system

(WIPS) and serving client data: thanks to the dedicated third radio,

Air Marshal, a highly optimized built-in WIPS, scans continuously

for threats and remediates them as commanded, all without

disrupting client service. Alarms and optional auto-containment of

rogue APs are configured via flexible remediation policies, ensuring

optimal security and performance in even the most challenging

wireless environments.

Advanced analytics

Drill down into the details of your network usage with highly granular

traffic analytics. Extend your visibility into the physical world with

journey tracking through location analytics. View visitor numbers,

dwell time, repeat visit rates, and track trends. View real-time,

per-radio spectrum analytics to troubleshoot nearby interference.

Analyze AP events, client utilization, and bandwidth usage on a

per-radio basis. Fully customize your analysis with raw data available

via simple APIs.
