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.
