(Wireless Speaker and Audio)

ワイヤレス伝送規格のWiSA (https://www.wisaassociation.org/)は、
5GHz/UNII (Unlicensed National Information Infrastructure)バンドの
無線帯域を併用することで最大96kHz/24bit、8チャンネルまでのオーディオ信号を、
最大11台のスピーカーに非圧縮のまま高品位にワイヤレス伝送する技術です。

Wireless transmission standard WiSA(https://www.wisaassociation.org/) enables high-quality wireless transmission of
up to 96 kHz / 24-bit, 8-channel audio signals to up to 11 speakers without compression using a combination of 5GHz/UNII(Unlicensed National Information Infrastructure) band.

ロスレス非圧縮で遅延も僅か

送受信可能な距離は屋内で約10m、96kHz/24bitロスレス非圧縮伝送時の
レイテンシーは僅か2.6mS

Lossless, uncompressed with little delay

The transmission/reception distance is about 10m indoors, and the latency at 96kHz / 24bit lossless uncompressed transmission is only 2.6mS

音ズレのない
マルチチャンネル再生

補正回路搭載により複数スピーカー再生時のスピーカー間のディレイを
僅か約5μSに制御

Multi-channel playback without sound gap

The delay between speakers when playing multiple speakers is controlled to only about 5μS by the correction circuit.

音切れが非常に少ない
ワイヤレスオーディオ伝送

他の無線機器との干渉が発生した場合、5GHz/UNIIバンドも併用し
5GHz内の空いている帯域へ即座にシフトし音切れを回避

Wireless audio transmission with very few interruptions in sound

In case of interference with other wireless devices, 5GHz / UNII band is also used and shift to vacant band within 5GHz immediately to avoid sound interruption

※WiSAは、日本国内で使用可能な5.18GHz~5.24GHz帯の4チャンネル(36~48までのチャンネル)以外にも、「DFS(Dynamic Frequency Selection)」が義務づけられる「5GHz/UNIIバンド」を併用した技術です。

※「5GHz/UNIIバンド」は防衛・気象レーダーが優先的に使用する帯域の為、当該帯域を使用する際、防衛・気象レーダーが使っていないかを1分間ほどモニターしなければならないルールがあります。
WiSAでは当該帯域のチャンネルの空きを常時モニターするための送信機と通信用の送信機を設けるという独自技術により、5GHz/UNIIバンドをワイヤレスオーディオ用に活用できるようにしています。
また高精度なエラー訂正機能も実装されており、24bitのオーディオストリームデータに加え、8bitのエラー訂正信号を同時に送り出しながら、"FEC(Forward Error Correction)”というエラー訂正アルゴリズムによるオーディオデータの補正を受信機側で行っています。

* WiSA uses the 5GHz / UNII band, which requires "DFS (Dynamic Frequency Selection)", in addition to the 4.18GHz-5.24GHz band (36-48 channels) available in Japan.

* Because the 5GHz / UNII band is a band that is used by defence and weather radars preferentially, there is a rule that when using that band, you must monitor whether the defence and weather radar is not using for about 1 minute... WiSA has made it possible to utilize the 5GHz / UNII band for wireless audio by using a proprietary technology that includes a transmitter for constantly monitoring the available channels in the band and a transmitter for communication. Besides, a high-precision error correction function is also implemented. In addition to the 24-bit audio stream data, an 8-bit error correction signal is simultaneously sent out, and audio data is corrected using an error correction algorithm called "FEC (Forward Error Correction)". It is done on the machine side.
