Best Practices for Deploying ScreenBeam Miracast Over LAN

This article is applicable to ScreenBeam 1xxx-Series and 960 products.

Executive Summary

Wireless display is foundational for collaboration across enterprises and schools. While classic Miracast uses Wi-Fi Direct (peer-to-peer), Miracast over LAN routes discovery-initiated sessions over your existing wired/wireless network. When paired with ScreenBeam receivers, this approach scales better, is simpler to manage, and fits enterprise security models.
Scope note: Miracast over Infrastructure is only available on Windows 10/11 devices. 

How Miracast Over LAN Works (and Why It Helps)

Windows discovers ScreenBeam receivers using Wi-Fi Direct radio beacons. After discovery and hand-off, the media and control traffic traverse the LAN/WLAN (MOI).
Placement tip: Because discovery is RF-based, place receivers in proximity to user devices (same room is recommended).

Key benefits

  • Scalability: Concurrent sessions without consuming scarce Wi-Fi Direct spectrum.

  • Centralized management: ScreenBeam CMS + existing network tooling.

  • Security: Enterprise VLANs, authentication, and access controls.

ScreenBeam fit
ScreenBeam receivers support wired/wireless LAN operation and provide centralized configuration, monitoring, and updates.

Deployment Best Practices

1) Network Readiness & Capacity

  • Confirm LAN/WLAN bandwidth for the expected concurrency.

  • Use Gigabit Ethernet uplinks to minimize latency/jitter.

  • Validate switching/routing handles multicast reliably (used for discovery workflows and supporting services).

2) ScreenBeam Configuration

  • Update firmware to the latest release before pilot/rollout.

  • Enable Miracast over LAN in the receiver settings.

  • Assign DHCP reservations or static IPs for receivers; standardize naming (site-room-display).

3) WLAN Optimization (for wireless clients)

  • Prefer 5 GHz access for clients; survey spectrum and avoid congested channels.

  • Ensure WMM/QoS is enabled so real-time traffic isn’t deprioritized.

  • Do not disable Wi-Fi on Windows clients—Wi-Fi Direct is required for discovery even when streaming over LAN.

4) Multicast & Discovery

  • Enable IGMP Snooping on access/aggregation switches.

  • If senders/receivers span VLANs, configure multicast routing on L3 devices.

  • Validate discovery and session setup under realistic load.

5) Security Controls

  • Segment with VLANs; restrict admin interfaces to trusted networks.

  • Enforce WPA2/WPA3 on WLANs.

  • Gate access with ACLs, NAC, or MAC allowlists per policy.

6) Physical & Environmental

  • Prefer wired Ethernet to receivers where feasible.

  • Place receivers in-room, within typical Wi-Fi Direct range, minimizing obstacles.

  • Use cable management to prevent accidental disconnects.

     

    Pre-Deployment Checklist

    • Capacity validated; Gigabit uplinks confirmed

    • Wi-Fi Direct discovery tested in-room; receivers placed near users

    • IGMP Snooping enabled; multicast routing (if multi-VLAN) verified

    • DHCP reservations/static IPs; clear device naming

    • 5 GHz plan + WMM/QoS confirmed; spectrum surveyed

    • VLAN/ACL/NAC rules verified; admin access restricted

    • CMS monitoring configured; update/change cadence defined
