And then we have the electrical field, the electrical tilt is achieved by changing the face of.
The signal that is going to each of the antenna elements, for example, in this and enough, we can
see that there are four antenna elements.
And these are the signals that are going to these antenna elements and we change the phases of these
signals in such a way that we get the built in the beam that is generated by this antenna.
Here we can see that we are not physically building the antenna.
And one advantage of this deal is that the backlog is not lifted.
So this especially useful in the dense urban sites where we have small cells and those cells are near
to one another.
So as the back lobes and side lobes of the antena are not lifted.
So that means that no additional interference is generated to the neighboring cells.
And one other advantage of this electrical field is that it can also be achieved remotely from a central
location like operation and Maintenance Center, which is also known as the YMCA.
And that is why it is also called as the remote electrical field because it can be managed from a central
location in the network.
In some cases, we may require a larger entity not don't build branch for some applications.
So in that case, we may buy antennas that come with a preset electrical field that is built in to the
antennas.
And then you have the beam, digital build and beam digital tilt is a type of electrical field, but
this field is only used for broadcast and control channels, and this bill does not affect the dynamic
beams that are used for the traffic channels.
And this bill can be adjusted to a green reality ar.d resolution of one degree.
