WiSA Technology Featured In CEDIA Wireless Audio Whitepaper
By WiSA Staff Writers
Recently, the Wireless Speaker and Audio Association contributed to a CEDIA whitepaper called Wireless Audio Solutions: Technologies and Best Practices. Here is an excerpt:
Most computer networks avoid the DFS band because the process of monitoring channels and waiting the requisite 1 minute to acquire a clear channel can cause performance problems for those networks. This leaves a lot of free bandwidth in the DFS band in channels 52-65 and 100-140 as illustrated in Figure 2 below.
5 GHz Channels
A WiSA-compliant transmitter deals with DFS requirements quite naturally. Uncompressed audio is transmitted in packets at a constant rate and so, since not all of the bandwidth is used, radio monitoring can be hidden between packets and have no impact on performance. This means there is virtually no interference, which allows the clean transmission of 8 channels of 24-bit uncompressed audio, at up to 96 kHz. As a bonus, DFS monitoring on WiSA compliant devices means is extended to detect and avoid any type of interference, not just radar, is avoided by the technology providing to provide the best audio quality. There are plenty of DFS channels, so there is room for multiple systems. If convenient or necessary, the system may still use non-DFS frequencies; but DFS rules are still used to achieve interference-free operation.
