IEEE 802.11n/ac standard for transmission rates up to 1 Gbps. Choose between 5 GHz or 2.4 GHz band to minimize interference with other WiFi networks.


LAN-Network: Additional LAN port on base unit, to link mobile devices to a LAN network or internet whilst being connected to the Showmi receiver unit over WiFi.


Aurora - VLX-TC1-CF


The VLX Series utilizes Aurora’s IPBaseT technology, which synergizes various IP/AV standards to work together as one. It is reportedly the industry’s first 4K UHD transceiver with only 1.5 Frame (25ms) latency and visually lossless compression. Using a transmitter (encoder) and receiver (decoder), respectively, used to be the standard – until now. The VLX Series box or wall plates can be set up as either one to make installation, inventory, and troubleshooting easier. Another industry first is the option slot to add other IP capabilities, like Dante audio, for a more complete, distributed system. Audio, video, data, and control can be sent securely to one or many units using off-the-shelf 1G RJ-45 Ethernet switch. When the VLX is set up to be a transmitter, the 2 HDMI inputs (VLX-TC1-CF, VLX-TCW2H-C) or VGA/HDMI inputs (VLX-TCW2V-2) become a source switch and the HDMI output becomes a potential loop out. When set up as a receiver, a user can select the local HDMI inputs or an IP source. Fast-switching of the sources further enhances the presentation (Matching source resolutions and frame-rate required). Regardless of how the VLX is set up, the audio can be de-embedded at any location, and/or be sent to or received from a Dante enabled device. The USB is also flexible, working as a KVM and/or a high-speed data transfer (50Mbps) for memory sticks. Each VLX USB feature can also be set as a host or a device. To keep the system friendly, an OSD and integrated web server are available for easy navigation and setup of features. Digital signage, education, corporate, and residential are just a few markets which benefit from the flexibility and low cost of the VLX Series.

Key Features Include:

  • 4K visually lossless over 1Gbps network
  • Low 1.5 frame latency
  • 1080p to 4K, 4K to 1080p scaling
  • HDMI 2.0/HDCP 2.2
  • Secure Content Encryption
  • Unlimited scalability (based on network topology)
  • Videowall with image rotation
  • PoE (Power over Ethernet)
  • Stereo line I/O
  • RS-232 and IR Control Ports
  • Auto sense switching
  • USB 2.0 Host and Device Ports
  • Dante IP audio option

Viewsonic - ViewSync3


The ViewSonic ViewSync 3 wireless presentation gateway offers a convenient AutoProject function for USB wireless presentations. Whether in meeting rooms or classrooms, presenters can easily plug-n-project from their own laptops via a wireless auto-projection USB dongle, instead of using a VGA cable or traditional wireless presentation setups, decreasing setup time and cutting back on monotonous procedures.

With bundled presentation software, it helps the presentation host to enhance interaction capabilities in large-scale meeting/class environments. Moderator mode allows 50+ simultaneous connections from attendees’ PCs or NBs. The host can preview all connected screens before broadcasting, and can choose any linked screen to present. In seconds, the chosen presenter’s ideas can be shared with all.

The ViewSync 3 supports laptop wireless 2.4G / 5GHz projection, Screen Mirroring and DLNA Media Streaming from your tablet or smartphone. It can support any of the above connection protocols and devices without a manual switch. Users can quickly connect to the ViewSync 3.

2.4GHz is a very popular bandwidth for most wireless devices, which can easily cause transmission lag. The advantage of a 5GHz network is that it can have twice the link speed, which increases the quality for multi-media broadcasting. WiFi Dual Band support utilizes flexible usage, by providing either 2.4G or 5GHz network.

The bundled software allows real-time annotations on content displayed from Windows or Mac laptops. These changes can be saved and updated instantly, allowing the presenter and laptop-connected audience simple, yet effective interaction.

BenQ - InstaShow


BenQ’s InstaShow wireless presentation system removes challenges like restricted number of users, wrestling with cables and logging onto the network and speeds up learning by enabling users to wirelessly present by simply plugging in the InstaShow button to their devices and tapping it to share content to projectors and flat panels in the room. There is no software or app in order for it to run on a laptop, and no need to log onto the school’s network, and with its standard HDMI interface – will connect to any HDMI classroom source such as document cameras, media players, and digital microsopes. The system also sets a new benchmark in the number of participants or devices that can be shared, with up to 16 students (InstaShow WDC10 model) or even up to 32 students (InstaShow S WDS20 model) connected to the system. With InstaShow, not only does the whole class have the potential to join in, but up to four students at a time can share their screens simultaneously to the display instead of the typical two that are allowed with most systems.

The latest model, which released in Q4 2019, InstaShow S, supports mobile phone and tablets as well as allowing Windows laptop users working in classrooms with interactive displays to command their laptop right from the touch screen, opening files, controlling video playback, changing documents, and then saving them to their notebook. There’s no running back and forth from laptop to the front of the classroom. Now teachers and students can present and learn at the speed of the future.

InstaShow S can maintain stable wireless connections even in less-than-ideal Wi-Fi environments. Equipped with Wi-Fi 802.11 ac/n for transfer speeds of up to 700Mbps*, InstaShow S facilitates easy and smooth sharing of presentations, pictures, documents, and Full HD video.
