MR42

Dual-band 802.11ac Wave 2 access point with separate radios

dedicated to security, RF management, and Bluetooth

High performance 802.11ac

Wave 2 wireless

The Cisco Meraki MR42 is a four

radio, cloud-managed 3x3 MU-MIMO

802.11ac Wave 2 access point. Designed

for next-generation deployments in

offices, schools, hospitals, shops, and

hotels, the MR42 offers performance,

security, and simple management.

The MR42 provides a maximum 1.9 Gbps

frame rate with concurrent 802.11ac Wave

2 and 802.11n 3x3:3 MIMO radios. A

dedicated third radio provides real-time

WIDS/WIPS with automated RF optimization.

In addition, an integrated fourth radio

delivers Bluetooth Low Energy (BLE)

scanning and Beaconing functionality.

With a combination of cloud management,

high perfomance hardware, multiple

radios, and advanced software features,

the MR42 makes an outstanding platform

for the most demanding of uses today and

tomorrow. These uses include high-density

deployments and support for applications

like voice and high-definition video.

MR42 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.

24/7 monitoring via the Meraki cloud

delivers real-time alerts if the network

encounters problems. Remote diagnostic

tools enable immediate troubleshooting

over the web, meaning multi-site, distributed

networks can be easily managed.

The MR42’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.

MR42 and Meraki cloud

management: a powerful

combination

Management of the MR42 is handled

through the Meraki cloud, enabling

rapid deployment across multiple sites

without the need for time-consuming

training or costly certifications. Since the

Features

Aggregate data rate of up to 1.9 Gbps

A 5 GHz 3x3:3 radio and a 2.4 GHz 3x3:3

radio offer a combined aggregate dual-

band frame rate of 1.9 Gbps. Supports up

to 1,300 Mbps in the 5 GHz band and 600

Mbps in the 2.4 GHz band. Technologies

like transmit beamforming and enhanced

receive sensitivity allow the MR42 to

support a higher client density than typical

enterprise-class access points, resulting

in fewer APs for a given deployment.

The MR42’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 RF analysis data

collected by the dedicated third radio

is continuously fed back to the Meraki

cloud. This then automatically tunes

the MR42’s channel selection, transmit

power, and client connection settings

for optimal performance under even

the most challenging RF conditions.

per user group, or per individual user.

Voice and video optmizations

Industry standard QoS features are easy

to configure and come built in. Wireless

Multi Media (WMM) access categories,

802.1p, and DSCP industry standards

all ensure important applications get

priorotized correctly, not only on the

MR42, but on other steps in the traffic

flow. Unscheduled Automatic Power

Save Delivery (U-APSD) ensures minimal

battery drain on wireless VoIP phones.

Multi User Multiple Input

Multiple Output (MU-MIMO)

With support for the 802.11ac Wave 2

standard, the MR42 offers MU-MIMO for

efficient transmission to multiple clients.

Especially suited for enviroments with

numerous mobile devices, MU-MIMO

enables multiple clients to receive

data simultanously. This increases

the total network perfomance and

improves the end user experience.

Integrated enterprise security and

guest access

The MR42 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

granular access control at the group or

device level. PCI compliance reports check

network settings against PCI requirements

to simplify secure retail deployments.

Low-profile, modern, user

friendly design

Despite its extensive capabilities, the

MR42 is packaged in a sleek, low-profile

enclosure that blends seamlessly into

any environment. This makes it ideal for

modern offices, high end retail locations,

and discrete deployments. Using human

interface design principles, even the

physical installation and mounting

experience has been developed to eliminate

error and simplify installation process.

Third radio delivers 24x7 wireless

security and RF analytics

The MR42’s sophisticated, dedicated

dual-band radio scans the environment

continuously, characterizing RF interference

and containing wireless threats like

rogue access points. No longer 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.

Self-configuring, self-maintaining,

always up-to-date

When plugged in, the MR42 automatically

connects to the Meraki cloud, downloads

its configuration, and joins the appropriate

network. If new firmware is required,

this is retrieved by the AP and updated

automatically. This ensures the network is

maintained with bug fixes, security updates,

and new features managed for you.

Enterprise Mobility Management

(EMM) & Mobile Device

Management (MDM) integration

Meraki Systems Manager natively integrates

with the MR42 to offer simple automatic

security that is context aware. Rapidly

deploy self-service MDM enrolment without

installing additional equipment or dynami-

cally tie firewall policies to client posture.

End-to-end security has never been so easy.

Bluetooth Low Energy Beacon

and scanning radio

An integrated fourth radio for Bluetooth

Low Energy (BLE) provides seamless

deployment of BLE Beacon functionality and

effortless visibility of BLE devices. The MR42

enables the next generation of location-

aware applications while futureproofing

your deployment, making it ready for any

new customer engagement strategies.

Advanced analytics

Drill down into exceptional detail with

highly granular traffic analytics. Understand

how your network is used with access to

numerous datasets. Extend your visibility

to the physical world with journey tracking

through location analytics. View vistor

numbers, dwell time, repeat visit rates, and

track trends. Fully customize your analysis

with raw data available via simple APIs.

Application-aware traffic shaping

The MR42 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. Importantly, controls can

be implemented per network, per SSID,
