Tsab ntawv xov xwm no muab cov kev tshuaj xyuas zoo ntawm qhov kev hloov pauv ntawm lub hauv paus chaw nres tsheb kav hlau txais xov thev naus laus zis thoob plaws kev sib txuas lus mobile, los ntawm 1G txog 5G. Nws taug qab yuav ua li cas cov kav hlau txais xov tau hloov pauv los ntawm cov teeb liab yooj yim transceivers rau hauv cov txheej txheem sophisticated uas muaj peev xwm ntse xws li beamforming thiab Massive MIMO.
**Core Technological Evolution los ntawm tiam**
| Era | Ntsiab technologies & Breakthroughs | Tus nqi tseem ceeb & kev daws teeb meem |
| **1G** | Omnidirectional kav hlau txais xov, spatial ntau haiv neeg | Muab kev pab them nqi kawm ntawv; txhim kho uplink ntawm spatial ntau haiv neeg nrog tsawg cuam tshuam vim qhov chaw nres tsheb loj. |
| **2G** | Kav hlau txais xov Directional (sectorization), dual-polarized antennas | Ua kom muaj peev xwm thiab kev pab them nqi ntau dua; dual-polarization enabled ib tug kav hlau txais xov los hloov ob, txuag chaw thiab ua kom denser xa mus. |
| **3G** | Multi-band antennas, tej thaj chaw deb hluav taws xob qaij (RET), multi-beam antennas | Txhawb nqa tshiab zaus bands, txo tus nqi ntawm qhov chaw thiab kev saib xyuas; enabled tej thaj chaw deb optimization thiab multiplied peev nyob rau hauv hotspots. |
| **4G** | MIMO kav hlau txais xov (4T4R/8T8R), ntau qhov chaw nres nkoj kav hlau txais xov, integrated kav hlau txais xov-RRU tsim | Dramatically txhim kho spectral efficiency thiab system peev xwm; hais txog multi-band multi-mode coexistence nrog kev loj hlob kev koom ua ke. |
| **5G** | Loj MIMO AAU (Active Antenna Unit) | Tau daws cov teeb meem tseem ceeb ntawm kev pab them nqi tsis muaj zog thiab muaj peev xwm xav tau los ntawm cov kab loj loj thiab cov kab hluav taws xob meej. |
Txoj kev evolutionary no tau tsav los ntawm qhov yuav tsum tau sib npaug plaub qhov kev xav tau: kev pab cuam piv rau lub peev xwm, kev qhia tshiab spectrum piv rau hardware compatibility, lub cev qhov chaw txwv tiv thaiv kev ua tau zoo, thiab kev ua haujlwm tsis yooj yim piv rau network precision.
Saib ua ntej, 6G era yuav txuas ntxiv txoj hauv kev mus rau ultra-loj heev MIMO, nrog cov kav hlau txais xov hais txog ntau txhiab leej, ntxiv tsim cov kav hlau txais xov thev naus laus zis raws li lub hauv paus ntawm cov xov tooj ntawm tes tom ntej. Kev tsim kho tshiab hauv cov kav hlau txais xov thev naus laus zis vividly tsom rau kev nthuav dav ntawm kev lag luam kev sib txuas lus mobile.
