Differences between V, U and WI-FI segments of conference microphones

We all know that the amount of information is determined by the frequency of electromagnetic waves. The narrower the frequency, the longer the transmission distance, the smaller the loaded data. The wider the frequency, the shorter the transmission distance, and the larger the loaded data volume.

Generally, the V band is narrow, the U band is wider, and the Wi-Fi band is the widest. Therefore, according to this sort, most of the V segment is applicable to long-distance services such as radio, walkie talkie, and space communication; most of the U segment is applicable to close-up services such as televisions and conference systems;

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, because of its advantages of access anytime, anywhere, in recent years, it has gradually been applied to close-up services such as conference systems.

Now with the development of technology, the processing of sound is becoming more and more professional. The three frequency segments used for 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 limit of the frequency band.

So what are the differences between the three bands?

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

The U segment is a high-frequency transmitting and receiving device. Therefore, the requirement for the electronic component is higher than that of the V segment, and the technical content is also much higher. In terms of practical application, the U section greatly reduces the chance of interference because it avoids most of the daily life bands;

Another real problem is that, in terms of the product itself, the hardware of the U segment is better than that of the V segment, and the production cost is lower than that of the V segment, therefore, in the field of conference systems, the replacement of segment V gradually becomes 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, encryption protection of conference content and other advantages, gradually become the darling of the conference system, and the application scope is constantly expanding.

But it is undeniable that the application of WI-FI technology in the conference system also has some problems, such as the number of users at the same time, when a large scale of participants, sufficient communication channels are required to meet the needs of potential users;

Another tricky problem is anti-interference. Although more and more mobile and fixed terminals have Wi-Fi functions, at the same time, more and more interference devices such as mobile phones, routes, and projections are also entering the conference system. Therefore, how to improve the stability of the Application of conference system equipment is also one of the problems that the conference system manufacturers urgently need to solve.

In general, V segment has become the trend of the past, the rise of WI-FI is a strong trend, but due to technical reasons, the U segment can not shake the Overlord position in the conference system.
