WiFi and Bluetooth are off-the-shelf wireless technology. They are working on 2.4GHz ISM band. ISM bands are license-free, free to use in any kind of devices, so they have serious interference. WiFi is design for home network, it is not an appropriate technology for audio streaming.
With our 20+ year wireless experience, we reform DECT protocol for HiFi audio application, adding audio mandatory elements, completely resolve wireless audio problem.
We have put key HiFi audio criteria into DECT audio protocol :
DECT brings perfect soundstage because of its highly accurate timing characteristic. Unlike Bluetooth, Wi-Fi or WiSA, DECT has a time resolution down to 0.1uS. ONEaudio can keep speaker synchronization as low as 0.5uS steadily even in worst condition, which is hundred time better than Wi-Fi and Bluetooth.
Unlike from Bluetooth and Wi-Fi, DECT has dedicated channels with no sharing of data bandwidth. This ensures sound stability and quality. DECT does not suffer from cloudy channel signals and data sharing congestion which often happen in Wi-Fi and Bluetooth devices.
DECT dedicated simultaneous multi-channel broadcasting protocol, each speaker can have its own dedicated channel to replicate a wired system. Delivering to each speaker the sound intended reducing lag and improving sound quality!
DECT protocol is design for instant voice communication. Short time delay between transmitter and receiver bring no visible lip sync in movie play. ONEaudio surround set can achieve same level as of wired AV system.
WiFi and WiSA never are battery operation, only DECT wireless speaker can be powered by battery. A full charge of ONEmini speaker has 100 hours play time !
By DECT technology, we have the World’s only TRUE wireless surround, without speaker cable and power cord. The true wireless 5.1 technology bring us award winning 2016 : CES Innovation Award and DECT Innovation Award.
DECT is low radiation device, only 1/10 of WiFi and 1/20 of WiSA, put your body in safe place.
DECT is not high data rate protocol, it can guarantee a constant data rate for lossless audio streaming. Even DECT is working at 1/10 power of WiFi, it can have longer range and better penetration.
Secondary re-transmission degraded the sound quality
Bluetooth stereo speakers run on master and slave configuration.
Master speaker is primary channel receive compressed L+R audio. Master speaker decompress L+R audio, retrieve R audio, compress R audio and re-transmit to slave speaker.
Slave speaker R audio has serious distortion and time error. You can only listen L channel and R channel sound on master speaker and slave speaker, but you never experience sound stage and sound imaging.
