's Answer
Electrical tilt (which was introduced in Second-generation cellular antennas) where the beam is 'tilted' by altering the signal phasing. This solution offers an undistorted azimuth beam plus the distinct advantage of tilting all lobes (main, rear and side) to the same measure, thus controlling interference in all directions. It was somewhat limited, being available only in discrete steps. Hence in The development of the third-generation cellular antenna, which features "adjustable electrical tilt" which allows cellular operators to continuously tilt the antenna, enabling optimisation of coverage and interference reduction without compromise. This technology has proved particularly useful for suppressing detrimental side lobe radiation. The latest antenna development by Radio Frequency Systems is the introduction of remote electrical tilt. This new technology extends the convenience of variable electrical tilt by relocating the tilt adjustment facility from the antenna body to the tower base or the network management centre. In an age where fast and efficient network tuning is becoming critical, remote tilt technology will provide substantial site optimisation benefits.
