What is Future Trend of 4G Antenna?

Distribution of 4G antennas: directional antennas are used outdoors. The direction of 4G antennas should be better pointed towards the transmitting base station as much as possible to achieve better reception. Omni directional antennas can be used indoors. The installation height is 2-3 meters (the number of antennas and location is related to the indoor area and indoor structure).  Only one antenna is required for an indoor unobstructed range of 300 square meters. Two antennas for a range of 300-500 square meters, and three antennas for a range of 500-800 square meters.

The signal amplifier is mainly selected according to the area of the area to be covered by the signal and the structure of the building. If the signal is too weak, the coverage will be incomplete, but if the signal is too strong, it will interfere with the outdoor signal.
The recommended installation distance of the signal amplifier is about 2 meters above the ground.  The distance between the indoor and outdoor antennas should be shorter, because the longer the line, the weaker the signal.
The use of wires: The feeder radio and television standard of the mobile phone signal booster is 750. but the mobile phone signal amplifier is the communication industry, 500 is the standard, and the impedance is not correct will make the system indicators worse. The thickness of the wire is determined according to the actual situation on site. The longer the wire, the thicker the wire should be used to reduce the signal attenuation. Before powering on the equipment, all indoor and outdoor antennas should be connected to avoid damage to the equipment. Indoor and outdoor antennas should be installed on different planes as much as possible.
In the future, the antenna will realize intelligent beamforming, beam pointing control, beam splitting and remote control, and flexibly meet the application requirements of various scenarios. Realize the interoperability between systems and the optimized utilization of resources through the intelligent antenna, and realize the intelligent operation and maintenance method.

Wireless networks have developed from signal coverage type to information capacity type, high-speed quality type. From low-speed and narrow-band to high-speed and broadband. The network structure is complicated, multiple generations and multiple networks coexist, multi-layer wireless network overlapping coverage, multiple antenna technology, and distributed development of urban wireless networks. With the rapid development of mobile communication technology, changes in network structure, continuous innovation of base station antenna technology, antennas are becoming active and intelligent, and multi-frequency and ultra-wideband applications are unstoppable.
