The Yealink CPW90 is a wireless expansion microphone pod designed to seamlessly integrate with the Yealink CP960 conference phone, transforming it into a more flexible and comprehensive audio conferencing solution. This device operates on dedicated digital wireless technology, typically in the 1.9GHz DECT or similar license-free band, to provide a secure, stable, and high-quality audio link free from the interference commonly associated with Wi-Fi or Bluetooth connections. Its primary function is to extend the microphone pickup range of the base unit, allowing meeting participants to be clearly heard even when seated several meters away from the main console. This effectively addresses the common challenge of limited built-in microphone reach in conference phones, enabling more natural meeting dynamics where participants can speak from their seats around a table without needing to cluster around a single device.

The CPW90 unit is designed as a compact, discreet pod that can be placed centrally on a conference table. It houses an omnidirectional microphone array optimized for 360-degree voice capture, ensuring balanced audio pickup from all directions. The device features advanced acoustic algorithms for noise reduction and echo cancellation, working in concert with the processing in the CP960 base to suppress ambient room noise, keyboard clicks, and air conditioning hum, thereby enhancing speech clarity for remote call participants. The wireless connection is established through a simple pairing process, and the system supports the simultaneous use of multiple CPW90 expansion mics with a single CP960, allowing for larger room coverage or more granular audio capture in very spacious meeting areas.

Built for professional office environments, the CPW90 features a robust construction and a simple, user-friendly design. It includes intuitive status LEDs to indicate power, wireless link status, and mute activity. The unit is typically powered by an included AC adapter or via USB, ensuring continuous operation without battery management concerns. For organizations that have standardized on Yealink conference solutions, the CPW90 provides a critical and scalable enhancement, effectively upgrading a high-quality desk phone into a powerful, room-filling conferencing system that delivers clear, full-duplex audio capable of supporting productive and natural-sounding meetings in mid-sized conference rooms.
