Conference room wireless screen sharing works in one of three ways: native sharing built into your meeting room system (Teams Rooms, Zoom Rooms or Google Meet hardware), a wireless presentation receiver that accepts AirPlay, Miracast or Google Cast from laptops and phones, or a button-and-dongle system where guests plug in a USB transmitter and press to share. If the room already runs Teams or Zoom Rooms, start with native sharing. Add a receiver like the Yealink RoomCast E2 when guests need to share without the meeting app.
Your options
| Method | How guests share | Needs app or account? | Best for |
|---|---|---|---|
| Native Teams Rooms sharing | Join the meeting from a laptop and share, or cast to the room | Teams | Teams-standard companies |
| Native Zoom Rooms sharing | Share from Zoom app, or enter the room's sharing key | Zoom app | Zoom-standard companies |
| Google Meet hardware | Present from a laptop in the meeting, or cast from Chrome | Google Meet / Chrome | Google Workspace offices |
| AirPlay / Miracast / Google Cast receiver | Built-in OS casting from Mac, iPhone, iPad, Windows, Android, Chrome | No | Visitors, mixed devices, classrooms |
| Button and dongle | Plug USB button into laptop, press to share | No (may need a small app first time) | Mixed guests, simplest for non-technical users |
| Wired fallback | HDMI or USB-C cable at the table | No | Always keep one as backup |
Native sharing in Teams, Zoom and Meet
Teams Rooms. People share content by joining the same meeting from their laptop (audio muted) and clicking Share. Teams Rooms also supports proximity-based join and casting from the Teams app on supported devices. See Teams Rooms content sharing and proximity join.
Zoom Rooms. Zoom Rooms shows a sharing key on screen. Guests enter it in the Zoom app to share, with or without a meeting. Zoom Rooms can also accept direct sharing via ultrasonic proximity. See how to use Zoom Rooms.
Google Meet hardware. Present from your laptop by joining the room's meeting, or cast a Chrome tab. See Google Meet hardware.
Native sharing is free and secure, but it assumes guests have the app and are on the network.
AirPlay, Miracast and Google Cast receivers
A wireless presentation receiver connects to the room display by HDMI and accepts standard casting protocols:
- AirPlay from Mac, iPhone and iPad.
- Miracast from Windows and many Android devices.
- Google Cast from Chrome and Android (on receivers that support it).
The Yealink RoomCast E2 supports AirPlay and Miracast, outputs 4K60 and can show up to four sources at once. See RoomCast AirPlay and Miracast and the RoomCast E2 guide.
AirPlay generally needs the device and receiver on the same network, or a receiver hotspot. Miracast can connect device-to-device over Wi-Fi Direct. Plan the network with IT before deploying.
Button and dongle systems
A USB button plugs into the laptop and pairs with the room receiver. Press the button and the screen appears. It's the easiest option for visitors because there's nothing to configure. Barco ClickShare is the best-known brand. The RoomCast line supports Yealink's WPP20 presentation button; see RoomCast button pairing.

Wired BYOD: when a cable is better
Wireless sharing sends only the screen. If a guest wants to run their own Teams, Zoom or Webex call using the room's camera and mics, they need a wired BYOD connection:
- Logitech Swytch: one cable from laptop to a PC-based room's camera and display.
- Logitech Extend: single-cable USB-C BYOD for Rally Bar rooms.
- Yealink MVC-BYOD-Extender: adds laptop BYOD mode to Yealink Windows Teams Rooms.
How to choose
- What platform do you run? If everyone uses Teams or Zoom, native sharing covers most needs.
- Who presents? Visitors and mixed devices push you toward AirPlay/Miracast or a button.
- Do guests need the room camera? Then add wired BYOD.
- What does IT allow? Guest networks, Wi-Fi Direct and receiver hotspots all need sign-off.
- How many sources at once? Some receivers show split screens for side-by-side comparisons.

Wireless room setup checklist
- Mount the receiver near the display and connect HDMI and Ethernet.
- Put the receiver on a network guests can reach, or enable its hotspot.
- Change the default admin password.
- Pair any presentation buttons.
- Post simple "how to share" instructions on the table.
- Keep a wired HDMI or USB-C cable as a fallback.
