A wireless presentation system lets people share a laptop, tablet or phone screen to the meeting room display without plugging in a cable. It has two parts: a receiver (base unit) connected to the display by HDMI, and a way to send from each device, either a USB button, a downloadable app, or the device's built-in casting (AirPlay, Miracast, Google Cast). "Collaboration" or "conferencing" systems add BYOD video calls, so the laptop can use the room's camera and speakers.
How it works
- The receiver connects to the TV or projector by HDMI and to your network (wired, Wi-Fi, or its own hotspot).
- A user picks a sending method:
- Button or dongle: plug into USB-C or USB-A, press to share. No software install on most systems.
- App: install the vendor's app, enter the room code shown on screen.
- Native casting: AirPlay from a Mac or iPhone, Miracast from Windows, Google Cast from Chrome or Android.
- The receiver decodes the stream and shows it, often with several sources side by side.

Presentation vs collaboration vs conferencing
| Type | What it does | Typical use |
|---|---|---|
| Presentation | One or more screens shared to the display | Slides in a meeting room |
| Collaboration | Multi-source, annotation, touch-back, moderator control | Classrooms, project rooms |
| Conferencing (BYOD) | Also links the laptop to the room's USB camera, mic and speakers | Laptop runs the Teams, Zoom or Meet call |
Systems advertising "up to 4 PCs" or "quad view" can show four sources on the display at once. Check the maximum simultaneous sources and how many devices can be connected (they're often different numbers).
Do you need one in a Teams or Zoom Room?
Often not. Microsoft Teams Rooms and Zoom Rooms already include wireless sharing from their own apps, and most appliances have an HDMI input. A dedicated system adds value when:
- Guests without your accounts present often.
- People want to share without starting a meeting.
- You need native AirPlay or Miracast for mixed devices.
- The room is a BYOD room where laptops run the call.

BYOD conferencing
In a BYOD room the user's laptop runs the meeting. A conferencing-capable wireless system (or a one-cable link) passes the room camera, mics and speakers to the laptop so remote participants see and hear the room. One-cable alternatives:
- Logitech Swytch for PC-based rooms
- Logitech Extend for Rally Bar rooms
Common brands
- Barco ClickShare: button-first, premium. See ClickShare alternatives.
- Yealink RoomCast E2: AirPlay, Miracast and YeaCast; Yealink's WPP30 button isn't sold in the US. See RoomCast setup.
- Mersive Solstice: multi-user collaboration with app and native casting.
- Crestron AirMedia, Kramer VIA, Airtame and others.

Where to download the app
Each vendor publishes its sending app on its own support site and, for mobile, in the App Store and Google Play. Many systems also show a download link or QR code on the room display. If your system supports AirPlay, Miracast or Google Cast, no app is needed for those devices.
Price ranges
Prices vary widely by brand and features. Roughly:
| Tier | What you get |
|---|---|
| Entry | Single-source casting receiver, native protocols only |
| Mid-range | Multi-source, buttons optional, central management |
| Premium | Buttons included, BYOD conferencing, enterprise security and management |
Budget extra for buttons (sold individually or in packs), multi-year support and licenses on some platforms. Check current pricing with each vendor.
Network and security considerations
- Decide whether guests join the corporate network, a guest VLAN, or the receiver's own hotspot.
- Native casting uses discovery protocols (Bonjour/mDNS for AirPlay) that may not cross VLANs without configuration.
- Look for encryption, firmware updates and central management if you have many rooms.
