Different antenna configuration schemes for point-to-multipoint wireless digital bridges

Point-to-multipoint wireless digital bridges can connect multiple discrete remote networks into a single structure, which is more complex than point-to-point wireless bridges. Point-to-multipoint wireless digital bridges often use a network as a central point to send wireless signals, and other receiving points perform signal reception. The central antenna uses different central antenna configurations in different projects:

Omnidirectional antenna: The omnidirectional antenna distributes the signal evenly around the center point in a 360-degree range, which is suitable for situations where the link points are close together, the distribution angle range is large, and the number is large;

Sector Antenna: The sector antenna has an energy-oriented aggregation function, which can effectively cover 180, 120, 90, and 60 degrees horizontally. Therefore, if the remote link point is concentrated in a certain range of angles, the sector can be used as a fan. antenna;

Directional antenna: The directional antenna has the strongest energy aggregating ability and its signal directivity is excellent. Therefore, the use of directional antennas is the most effective solution when the number of remote link points is small or the angular orientation is quite concentrated;

Combined antennas: Each of the above three types of antennas has certain characteristics. Therefore, in actual projects, it is often the case that combinations are used, such as the use of multiple sector antennas, or combination of sector antennas and directional antennas.
