About This Chapter

The HUAWEI VPM220W wireless microphone array (VPM220W) is a wireless audio pickup device that can seamlessly integrate with HUAWEI TEX0 series videoconferencing endpoints and HUAWEI DP300 videoconferencing endpoint.

The VPM220W uses three microphones spaced 120 degrees apart, offering 360-degree audio pickup at a radius of up to 6 meters. The VPM220W offers premium audio input to videoconferencing endpoints, significantly contributing to a more pleasant conference experience.

1 Overview

1.1 Features

Flexible Access



The VPM220W connects to a videoconferencing endpoint over Wi-Fi. When you use the VPM220W for the first time, you will need to manually search for an available Wi-Fi network. The next time you use the VPM220W, it automatically connects to the same endpoint.



The VPM220W can be easily moved based on the number of meeting participants and the layout of the venue. This avoids the inconvenience associated with wired microphones.



The VPM220W network is simple and because its microphones directly communicate with the videoconferencing endpoint over Wi-Fi, it ensures stable signals and strong anti-interference capabilities. However, the VPM220W does not support cascading.

Reliable and Easy to Use



The VPM220W has a mute button on top of the device. Tapping the mute button will mute or unmute all the VPM220Ws of the same site.



You can use the VPM220W directly after it starts up without performing any additional configurations.



The VPM220W is equipped with a rechargeable battery and comes with a charger base that can recharge one or more VPM220Ws simultaneously. A fully charged VPM220W provides up to 8 hours of active time and 24 hours of standby time.

The VPM220W supports 360-degree audio pickup at a radius of up to 6 meters.



The VPM220W delivers high-quality audio using frequency compensation technologies.



The VPM220W supports both mono and stereo applications.

Low Power Consumption



The VPM220W utilizes an energy-efficiency design. It consumes less than 2 W of power in active mode and less than 0.7 W in standby mode.



Videoconferencing endpoints, rather than the VPM220W, perform audio processing, which reduces the VPM220W's power consumption.
