The Cisco Meraki MR42 is a high-performance, cloud-managed wireless access point built for demanding enterprise environments such as offices, healthcare, retail, and education. With a powerful quad-radio architecture, including 3×3 MU-MIMO on 802.11ac Wave 2 and 802.11n, it delivers up to 1.9 Gbps in aggregate dual-band throughput ensuring seamless connectivity and high user density support.
The MR42 includes a dedicated dual-band third radio for 24/7 WIDS/WIPS, spectrum analysis, and location analytics. A fourth integrated Bluetooth Low Energy (BLE) radio provides support for beaconing and scanning, enabling advanced location-based services and asset tracking.
Automatic RF optimization through the Meraki cloud continuously adjusts channel selection, transmit power, and performance settings. The MR42 supports application-aware traffic shaping and is optimized for voice, video, and latency-sensitive applications. Integrated enterprise security features, including Layer 7 firewall policies and rogue AP containment via Air Marshal, ensure reliable protection across your network.
