Using Meraki MR57 IoT for Smart Door Locks (BLE Access Control Deployment)

Traditional door locks require separate hardware and infrastructure for monitoring and management. Electronic door locks, such as those from Meraki partners, simplify management, monitoring, and access control by centralizing the system on a dedicated server.

The Meraki MR57 is an Ultra-high-performance Wi-Fi 6E AP designed for the most demanding environments like offices, hospitals, and schools. Beyond its tri-band Wi-Fi connectivity (2.4 GHz, 5 GHz, and 6 GHz), the MR57 features a fifth integrated IoT radio. This integrated radio is key to next-generation applications, including the direct integration of IoT devices like smart door locks.

Part 1: Understanding the MR57’s IoT Capabilities

MR57 IoT Radio Capabilities

The Meraki MR57 provides a maximum aggregate frame rate of 7.78 Gbps. The integrated IoT radio delivers Bluetooth Low Energy (BLE) scanning and beaconing functionality, which is used for location-aware applications and visibility of Bluetooth devices. The MR57 also includes a USB port to support external devices for IoT applications.

The Role in Door Lock Integration

While the MR57 is capable of BLE scanning, its integration with electronic door locks from partners like Assa Abloy leverages the AP's IoT radio to function as a Zigbee Gateway. This approach allows customers to avoid running and maintaining parallel Zigbee and wireless infrastructures, thereby reducing operational overhead by unifying Zigbee and Wireless on one platform.

Crucial Note on Exclusivity: Enabling the Door Lock Integration on a Meraki network precludes other MR IoT functionality, most notably Zigbee. When the Door Lock Integration is active, Meraki APs will not transmit a BLE beacon or scan for nearby BLE devices.

Part 2: Real-World Deployment Examples

Office Building Access Control

For corporate offices or shared workspaces, electronic door locks enhance security with a pick-proof design and enable automated access management from a central control server. The MR57 acts as a gateway to streamline the management of numerous locks across multiple floors.

Campus or Multi-Building Deployment

In large deployments like campuses or hotels, the integration simplifies network architecture. Meraki AP models, including MR57, MR45, MR55, and outdoor models like MR76 and MR86, are supported as Zigbee gateways.

Small Lab or Shared Workspace Scenarios

Even smaller deployments benefit from the architecture, using the Visionline On-Premise Access Management System to configure, manage, and control the door locks, encode guest cards, and perform other guest-related functionality.

Part 3: Key Technical Considerations

Compatibility and Protocol

The primary documented integration is with electronic door locks from Assa Abloy. Supported models include VingCard Allure, VingCard Signature RFID, VingCard EssenceV2, and VingCard Classic RFID. The architecture utilizes Zigbee protocol messages between the door locks and the Meraki APs functioning as gateways.

Coverage and Interference Mitigation

To ensure stable performance, especially under high load:

• Scalability Limit: Recommended 4 door locks per gateway AP to account for CPU resources during high WiFi and MQTT load.
• RF Optimization: The MR57 includes a dedicated fourth radio for real-time WIDS/WIPS and automated RF optimization.

Network Configuration Requirements

APs must be selected to serve as the IoT Controller. Before enabling Doorlock Integration, the IoT Controller must be configured with a static IP address to generate a valid certificate enabling secure MQTT connection.

Part 4: Managing and Monitoring Smart Door Locks

Centralized IoT Management

The Meraki Dashboard provides visibility and control over the integration:

• IoT Controller Role: One AP (like MR57, CW9164, or CW9166) acts as middleware to configure, manage, and control registered MRs.
• Gateway Role: Other MRs function as Zigbee Gateways, connecting door locks to the VisionLine server via MQTT.
• Status and Visibility: The Dashboard provides insight into configured MR gateways and connected Assa Abloy locks.

Security and Updates

Meraki devices provide simplified management, including automatic firmware upgrades via the web to ensure network security.

Part 5: Choosing the Right APs and Procurement Tips

The MR57, classified as an Ultra-high-performance Wi-Fi 6E AP, is fully supported as an IoT Controller and Zigbee Gateway for the Assa Abloy integration.

• Wi-Fi 6E Indoor: MR57, CW9162, CW9164, CW9166.
• Wi-Fi 6 Indoor: MR45, MR55, MR36, MR44, MR46, MR56.
• Wi-Fi 6 Outdoor: MR76, MR86, MR78.

Part 6: Recommendations and Best Practices

Leveraging the MR57's integrated IoT radio for BLE access control deployment offers a unified, cloud-managed approach. IT teams can simplify security architecture by eliminating parallel wireless and Zigbee systems.

Deployment Best Practice: Proper AP placement, limiting 4 door locks per gateway AP, and confirming mutual exclusivity of BLE functionality ensure optimal performance.

FAQ (Meraki MR57 BLE, Smart Door Locks)

What is the core difference between MR57 BLE and its use in door locks?

The MR57 features an integrated radio for BLE scanning and beaconing. The partner integration uses the IoT radio as a Zigbee Gateway, which disables standard BLE functionality.

Which smart lock brands does MR57 IoT integration support?

Specifically documented for Assa Abloy models, including VingCard Allure and VingCard EssenceV2.

How far is the BLE signal range? Does it support multi-floor environments?

Four door locks per gateway AP is recommended. APs must be strategically placed as Zigbee gateways for multi-floor deployments.

How does the Meraki Dashboard manage a large number of BLE door locks?

An AP serves as IoT Controller; other APs act as Zigbee gateways registered to the Controller. Controller communicates with VisionLine server.

How are potential interference issues addressed during deployment?

MR57 includes a dedicated fourth radio for real-time WIDS/WIPS and automated RF optimization. Pairing limit reduces CPU strain and interference.

How can procurement ensure genuine products and timely delivery?

Router-switch provides global stocked inventory, rapid quotations, and ensures genuine product assurance.
