The difference between V segment, U segment and WI-FI segment of conference microphone

Author:admin   AddTime:2021-06-03

As you all know, the amount of information is determined by the frequency of electromagnetic waves. The narrower the frequency, the longer the transmission distance, and the smaller the loaded data; the wider the frequency, the shorter the transmission distance, and the larger the amount of loaded data.
Generally speaking, the V band is narrow, the U band is wider, and the WIFI band is the widest. Therefore, according to this order, the V segment is mostly suitable for long-distance services such as radios, walkie-talkies, and aerospace communications; the U segment is mostly suitable for short-distance services such as TV sets and conference systems; and the WI-FI network developed by the WI-FI Alliance , Is mainly used in the interconnection of personal computers, PDAs, mobile phones and other terminals. Due to its advantages of access anytime and anywhere, it has gradually been applied to short-distance services such as conference systems on a large scale in recent years.
However, with the development of technology, the processing of sound becomes more and more professional. The three frequency bands used in conference microphones have their own advantages and disadvantages. This is determined by the user of the frequency band, the physical characteristics of the frequency band, and the adjustment limits of the frequency band.
So what is the difference between these three bands?

It should be said that in actual production, the sound of the V-segment can be better than the U-segment and the WI-FI segment in any way, but due to the narrow band (180MHZ-280MHZ), generally more than 6 microphones will interfere with each other, and The stability is poor, far less stable than the U-segment and Wi-Fi segment.



The U-segment is high-frequency transmission and reception, so its requirements for electronic vitality parts are higher than that of the V-segment, and the technical content is also much higher. In practical applications, the U-segment avoids most of the daily life Band, so the chance of interference is greatly reduced; another real problem is that from the product itself, U-segment hardware is better than V-segment in all respects, and the production cost is lower than that of V-segment. In the field of conference systems, the U-segment gradually replaced the V-segment and finally became an unstoppable trend.
 In recent years, with the development of WI-FI technology and the improvement of market awareness, its stable and reliable WI-FI network, convenient and fast access anytime, anywhere, and encryption protection of meeting content have gradually made it a The darling of the conference system, the scope of application continues to expand.
 However, it is undeniable that the application of WI-FI technology in the conference system also has certain problems, such as the number of users accommodated at the same time. When encountering large-scale participants, it is necessary to prepare enough communication channels to meet the continuous demand of potential users. Enter; another tricky issue is anti-interference. Although more and more mobile and fixed terminals have Wi-Fi capabilities, at the same time, more and more interfering devices such as mobile phones, routers, and projections are also available. Enter the conference system. Therefore, how to improve the stability of the conference system equipment in the re-application is also one of the problems that the conference system manufacturer urgently needs to solve.
In general, the V-segment has become a trend of the past, and WI-FI is rising strongly, but due to technical reasons, the U-segment's dominance in the conference system cannot be shaken at present.
