A 5 GHz 3x3:3 802.11ac Wave 2 radio and a 2.4 GHz 2x2:2 802.11ac radio offer a combined aggregate dual-band data rate of 1.9 Gbps. Supports up to 1300 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.
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.
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 location-aware applications and engagement right out of the box.
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 challenging RF conditions.
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.
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. PCI compliance reports check network settings against PCI requirements to simplify secure retail deployments.
Application-aware traffic shaping
The MR42E features 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.
Voice and video optimization
Industry standard QoS features are easy to configure like Wireless Multi Media (WMM) access categories, 802.1p, and DSCP.
Low-profile, environment-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 excellent 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.
