Yue pond area vehicle-mounted sets wholesale hair piece, home delivery, large amount of merit, have intention to contact telephone WeChat bluetooth wireless communication specification as small category, larger advantage is that electronic products in the middle can according to the bluetooth wireless network connection, to eliminate the traditional cable connection.
Everybody everyday life more understand bluetooth headset, bluetooth stereo is the basic principle.
In recent years, interphone industry further combining with new technology new technology, bluetooth intercom there is a big improvement.
Intercom supplement bluetooth headset application, not only can release the voice of his hands, also can have our voice calls.
Cause the signal coverage to relay more close.
Although 5 g USES the Massive MIMO technology, but on the principle of it, if you need to reach speeds of more than 10 GBPS, every community to support the user is minimal, so the question comes, this part of the user who is it?
Only a few users, a village fee, that is to say, 5 g era is likely to be speed and flow rate of the double billing, extreme speed is relatively expensive.
So talkback voice calls, electronic fence light, movement, positioning, and other functions is negligible.
Explosion-proof design scheme of explosion-proof interphone might also include some spare parts explosion-proof circuit design scheme of rf connector.
Generally in petrochemical equipment, coal mine and coal power stations and other places use spare parts rf connector, rf connector should try to avoid spare parts show in risk in the air, in the case of without using dust cap can be adopted for covering and, of course, if can be based on circuit design scheme to improve parts explosion-proof type characteristics of rf connector will be more conducive to improve safety performance.
