5G is the fifth-generation communication technology. Its main features are wavelengths in the millimeter range, ultra-wide band, ultra-high speed, and ultra-low latency.1G realized analog voice communication, and the prototype mobile phone only made calls without a screen; 2G realized digitization of voice communication, that the function mobile phone had a small screen to send text messages;3G realizes multimedia communication with pictures and voice, available to gone through the picture with larger screen.4G realizes  high-speed local Internet access, large-screen smart phone can watch short videos. However, the signal much better in city rather than in rural.

1G ~ 4G are all focused on more convenient and faster communication between people, and 5G will realize the interconnection of everything at anytime, anywhere, and make humans expect to participate in the timeless synchronization of all things on earth through live broadcast.

The 5G communications era has dawned, Massive MIMO technology was introduced, which directly makes the 5G base station with 3 trends as below:

1. From passive antennas to active antennas;
2. Fiber replacement of feeder;
3. Integrated RRH and antennas; 

With the continuous evolution of communication networks to 5G, display antennas (multiantenna space division multiplexing), multi-beam antennas (network densification) and multi-band antennas (spectrum spreading) will become the main types of base station antenna development in the future.

With the advent of 5G networks, the needs of major operators for mobile networks are constantly changing. In order to achieve full network coverage, more and more types of base station ESC antennas are widely used in the field of mobile communications.

For four-frequency antennas, in order to control the electronic downtilt angle, there are three types of ESC control devices, including a combination of two built-in dual-motor ESC controllers, a dual-motor ESC controller with a transmission switching mechanism, and four ESC controller with built-in motor. Therefore, no matter which device, the antenna motor plays an vital role during its applications.

mission motor and a reduction gear box, which has a deceleration adjustment function; The transmission motor provides output speed and low torque speed. The gear box is connected to the transmission motor to reduce the output speed of the transmission motor, and at the same time increase the torque to achieve the ideal transmission effect. Base station ESC antenna motor gearbox usually adopts customized motor gearbox technical parameters, power, performance details to better match with the environment, climate, temperature difference, etc., in order to achieve the ideal transmission effect and service life requirements.
