How to Deploy Miracast

Why do my users need Miracast?

Miracast is a powerful addition to Solstice and will allow your users to wirelessly share content to a display without having to download software, install an app, or plug in a dongle. Now guests and other occasional users who don’t have the Solstice app installed can quickly and easily share content in the meeting space.

How does it work?

The Miracast feature works in two stages. In the discovery stage, a Miracast-enabled device searches for active Miracast receivers nearby for the user to connect and stream to.  This requires the Solstice Pod’s wireless network interface card to be enabled and not acting as a wireless access point. In the second stage, the device streams content to the Miracast receiver using either an existing network (Miracast over Existing Network) or a peer-to-peer wireless connection (WiFi Direct).

How do I enable and configure Miracast?

Step 1: Enable Miracast using the Solstice Dashboard. Find your Pod’s network configuration in the table below and apply the corresponding configuration in your Solstice Dashboard.

Pod’s Network Configuration Pod Configuration for Miracast via Solstice Dashboard
Ethernet Only (recommended)
  1. On the Network tab, enable Wireless Settings.
  2. Select Attached to Existing Network radio button to enable wireless antenna for Miracast discovery and click Apply. Do not attach the network interface to an existing network. This interface will remain idle and will only be used for the Miracast discovery stage.
  3. On the Appearance and Usage tab, enable Miracast – Stream video over WiFi Direct and over Existing Network.

Wireless attached to existing network only

On the Appearance and Usage tab, enable Miracast – Stream video over Existing Network.

Ethernet + Wirelessly Attached to Existing Network On the Appearance and Usage tab, enable Miracast – Stream video over Existing Network.
Ethernet + Wireless Access Point Miracast Not Supported. When the Pod is acting as an access point, Miracast discovery cannot operate. Contact Mersive to discuss other options like attaching your Pod to an existing network.

Step 2: Select Miracast Operating Mode.  Mersive’s implementation of Miracast supports two different modes for how video is routed from the source device to the Solstice Pod. Once you have determined which mode(s) you would like to use, configure them on the Appearance and Usage tab of the Dashboard.

Mode Devices Supported Performance Expectations
Over Existing Network and WiFi Direct (recommended) Win8, Win10, Android Allows Pod to dynamically select best video streaming mode. Most robust device connection and setup configuration.
Over Existing Network Windows 10 only Leverages existing network to support larger number of simultaneous Miracast users. All Miracast traffic is subjected to network security and monitoring.
WiFi Direct Win8, Win10, Android Good for use cases where one Miracast device will be used at a time.

Network Routing

The following network ports/routes are required to support Miracast streaming to Solstice Pods.

  • TCP port 7236: WiFi Direct control port used to establish and manage sessions between the source device and the Pod.
  • TCP port 7250: Port on which the Pod listens for Miracast packets when Over Existing Network mode is enabled.
  • UDP port 5353: If Miracast Over Existing Network mode is enabled, this port is used for multicast DNS (mDNS). mDNS is broadcasted to the local subnet of each network interface the Pod is connected to. If the computer that is attempting to make an infrastructure connection is on a different subnet, this broadcast will fail. If this happens, a workaround is to create a DNS entry to the Pod’s hostname.
  • Confirm that port 32768:60999 (for Gen2i Pods) is also open.

Important Considerations

Miracast requires that the Pod be located in close proximity to the display.  Miracast discovery operates over a range of approximately 150-200 feet. Only Pods within this range will be displayed in the Miracast source list on the client device.

Screen Key.  Screen key support for Miracast connections is available via WiFi Direct only. Screen key mode cannot be enabled when Miracast operates over an existing network. If you require the use of screen key, please ensure that you have enabled the WiFi Direct mode only.
