WiSA Technology Overview

The WiSA Compliance Test Specification (CTS) defines a set of attributes for Wireless Speaker and Audio technology that combine to deliver unmatched performance and ease of use for the home theater consumer. WiSA technology transmits 24-bit audio at sample rates up to 96k/second, with robust error recovery for uninterrupted listening enjoyment. With extremely low latency and negligible speaker-to-speaker delay, it offers flawless wired-quality performance and reliability.

WiSA technology operates in the relatively unused 5.2 to 5.8 GHz UNII radio frequency spectrum, reliably transmitting uncompressed HD audio from 2-channel stereo to 7.1 surround, along with system configuration and calibration data. Older wireless technologies, by contrast, operate in the same crowded frequency band used by cordless phones, baby monitors, security monitors, wireless Internet hubs, and microwaves—resulting in interference and poor quality audio.

The WiSA Association was created to provide an interoperability compliance program for speaker brands and manufacturers of CE devices. Consumers purchasing products bearing the WiSA logo can be confident that these products will work together flawlessly in the home theater environment. This level of compliance is especially critical for new and emerging technologies such as wireless audio.
