Can 3 base station sectors really achieve 360 degree coverage?

ThreeSectorsThe base station can achieve 360-degree coverage centered on the base station. Nowadays, the most common antennas for three-sector base stations are all 65-degree antennas. The 65-degree antenna in the communication industry refers to the antenna with a horizontal lobe angle of 65 degrees, and it is also called the horizontal half-power angle.

I prefer to call it a horizontal half-power angle, which is more intuitive.

The horizontal half-power angle reflects the concentrated intensity of the antenna energy, the antenna has the presence of the main lobe, and the energy in the central area is the strongest, and it slowly weakens to the sidesAnd when it reaches the position of half the power in the center, it is called half power, and the angle from the center to the half power is the half power angle.

The most common antenna is a 65-degree antenna, so an antenna coverage area is +-65 degrees, which adds up to 130 degrees. If the antenna is placed according to the default 0 degrees, 120 degrees, and 240 degrees for the three-sector base station, then there will be an overlapping coverage area of 5 degrees between every two sectors, and the three sectors can completely cover 360 degrees.

There are also many types of antennasThere are also 90-degree antennas, 30-degree antennas, and 360-degree omnidirectional antennas, and different antennas can be configured in various different areas.

Sometimes network optimization requires adjusting the key coverage areas of the base station, and it may also occur that the three sectors cannot cover 360 degrees.

The antenna can be adjusted, and how it is adjusted depends on what effect needs to be achieved. For example, in some hot spots, it may also be necessary to adjust the 2-3 antennas to align with a region coverage, at this time, due to the adjustment of the base station antenna, the base station may appear around the coverage hole, there will be base station signal coverage in other areas, this is also available, sometimes it is close to the base station, and it is also possible that it is covered by other base stations.

All in all, generally speaking, if there are no special requirements for network optimization adjustment, the three-sector base station will cover the surrounding 360 degrees by default.

Nowadays, the most common antennas for three-sector base stations are all 65-degree antennas.

Yes, you only need to adjust the adjustment angle to cover all aspects.

The three-sector base station can achieve 360-degree coverage centered on the base station.

Stacked coverage area, three sectors can completely cover 360 degrees.

No, the scope needs to be further expanded.

Almost, it's enough to have three sectors.

It's still difficult, and I feel like it's still less.

There is a certain degree of difficulty, after all, full coverage is difficult.
