5G est quintum generationem communicationis technology, maxime propria a millimetae, ultra wideband, ultra-summus celeritas, et ultra-humilis latency. 1G habet effectum Analog vocem communicationis et fratrem maximum habet screen et non solum phone vocat; 2G habet effectum digitization vocis communicationis, et ad munus machina habet parva screen quod potest mittere text nuntiis; 3G habet effectum multimedia communicationis ultra vocem et imagines, faciens screen maior pro imaginibus; 4G habet effectum loci summus celeritate Internet obvius, et magna screen Smartphones potest vigilate brevi videos, sed signum est bonum in urbana areas et pauper in ruralium. 1G ~ 4g focuses in magis convenient et agentibus communicationis inter homines, cum 5G erit enable internectionem omnium rerum, usquam, permittit homines audeat per synchroni participationem omnibus in terris per vivam streaming sine tempore.
In adventu 5G era et introductio ingens Mimo technology habere directe ducitur ad tria trends in progressionem 5G basi station antennas:
I) progressionem passivum antennas ad activae antennas;
II) fibra opticus replacement PASTOR;
III) et rrh (radio frequency remotis capitis) et antenna sunt partialiter integrated.
In continua evolutione communicationis retiacula ad 5g, ostentationem antennas (multi antennae spatium division multiplexing) multi trabem antennas (network de basi statione antenna progressionem in futurum.
In adventu 5g networks, postulationes major operators ad mobile networks sunt semper mutantur. Ut consequi plenam network coverage, magis et magis genera basi statione tuning antennas late in agro mobile communicationis. For the four frequency antenna, in order to achieve control of its electronic downward tilt angle, there are currently three main types of electrical adjustment control devices, including a combination of two built-in dual motor electrical adjustment controllers, a dual motor electrical adjustment controller with a transmission switching mechanism, and four built-in motor electrical adjustment controllers. Potest videri, quod nulla materia quae fabrica adhibetur, non potest separari a application of antennae motoribus.
Pelagus structuram de basi statione electrica tuning antennae motricium est motricium reducer integrated apparatus composito ex transmissione motricium et reductionem Gearbox, quod habet decalionem disparet munus; Motor providet output celeritate et humilis Torque celeritate et gearbox connectitur ad transmissionem motricium ad redigendum output celeritate transmissione motricium dum augendae ad torque, achieving effectus; Et basi statione Electric Tuning Antenas motor Gearbox solent adoptat customized motricium Gearbox technica parametri, virtus, et perficientur ad melius occursum environmental factores ut elit, in melius occursum environmental factors ut elit, caeli effectus et ministerium vitae requisita.
