Most Bluetooth headsets and 2.4G headphones are employed 2.4G frequency band for transmission, so from your wide feeling, each may be known as two.4G frequency transmission, but mainly because the transport protocol, dividing into Bluetooth and 2.4 G.
Due to the fact Bluetooth utilizes the ISM that open up to all wireless band, so it couldn't stay away from the signal interference from wireless, so the Bluetooth has created rapidly determine and reply to fast-hopping to strategy to wireless interference, like the ZONOKI Bluetooth Headset, which has divided the frequency band into quite a few hopping channel, inside a solitary connection, the radio transceiver based on a specific code sequence constantly from 1 channel " leap "to a further channel, only the sender and receiver to converse is according to this legislation, as well as other interference can't be interference because of the identical legislation; the instantaneous bandwidth of hopping is extremely slim, but by means of spread spectrum technologies to create the slim bandwidth hundredfold enlargement into broadband, to ensure that interference results could grow to be quite smaller.
Furthermore, due to the fact the pace of standard Bluetooth transfer is gradual, only 1Mbps, when the CD-level sound transmission requirements to attain 1.4Mbps, as a result standard Bluetooth can only eradicate high-frequency and very low frequency of audio, generating the sound broken. In watch from the conventional Bluetooth transfer pace restrictions, enhanced Bluetooth 2.1 + EDR technologies arrived into becoming, Bluetooth 2.1 + EDR technologies permits the pace of transmission as much as about 3 instances on the regular Bluetooth, upgrade to 2.1Mbps, totally meet the degree of the CD needs. this technologies is mirrored in N- B99.
For your 2.4G technologies, instead of Bluetooth technologies eliminates the troubles with the code, but in addition need to have a receiver. In the transmission talent , 2.4G and Bluetooth are comparable. Furthermore, immediately after enhancing 2.4G wireless technologies, with sixteen channels additionally automated frequency-hopping technologies, can resolve the interference situation. For instance, A headset using the receiver employing a channel, the outcomes of automated detection in the channel interference, it's going to instantly leap to yet another channel, to prevent the exist interference. Meanwhile, headsets and also the receiver use two-way communication technologies, which headphones mail packets towards the receiver, the receiver also suggestions packets towards the headphone, in comparison with one another, screening whether or not there's packet reduction there.
A lot more than several technologies that will make certain accuracy and timeliness of highest 2.4G wireless transmission, coupled using the transmission fee of 2.4G attain to 2.0Mbps, is far higher compared to quantity of CD 1.4Mbps transmission requirements, so that they could obtain lossless information transmission.
