In progressionem 4g LTE technology, 'Cattus (category) ' est frequenter terminum. Ex ingressum-gradu cat1 ad altus-perficientur Cat18, diversis genera abscondere precise iteration of communicationis technologiae. Hoc articulum incipiet a technica imo accumsan, analyze in definitione logicae, Core differentias et practica applications de LTE Categories, Auxilium 4G intellegere hoc key indicator quod afficit 4g fabrica perficientur.
I. De essentia LTE Categories Categories: A 'Classification Latin ' pro communicationis capabilities
LTE Categories non a specifica technology, sed perficientur classificationem ratio formari ab 3gpp (3 Generation societas Project) ad 4g terminales cogitationes. Core munus est ad define ad maximum facultatem terminales cum accessing lte networks per unifiendas technica Indicatores (ut rate, modulation modus, multi, antenna configuratione, etc.), quod cogitationes a diversis manufacturers potest operari simul in eodem network.
Tantum posuit, Categories sunt sicut 'communicationis facultatem testimoniales ' - quod altius cattus gradu, magis provectus technologies rate et firmamentum et fortior et ad rem deduci et firmitatem et fortior est ut rem deduceretur rate et stabilibus. Haec ratio fuit prima propositus in 3gpp release VIII (MMVIII) et continuously dilatatur cum technicis evolutione. Currently, quod est defined ad Cat20.
II. Tres core technical Indicatores determinandum cat Categories
Differentias inter alium cat Categories sunt per tres core technica parametri, quae una forma 'communicationis laquearia ' terminorum
I. Modulation Modus: Key ad Data 'Packaging Efficens '
Modulation technology determinat quantum notitia potest traducitur per unitatis tempore. In his modi modi sunt maxime in LTE :
QPSK : II bits data per symbolum (low-celeritate missionibus);
16QAM : IV bits of notitia per symbolum;
64QAM : VI bits data per symbolum (medium et summus celeritas missionibus);
256QAM : VIII bits data per symbolum (summus velocitate missionibus, sustinetur a cat6 et supra).
Exempli gratia, cat4 tantum sustinet 64QAM , dum Cat6 introducit 256QAM , quod crescit notitia tradenda efficientiam a XXXIII% sub eadem Sed.
II. Portitor aggregatio (CA) Bandwidth 'splicing ' Technology
Una carrier Bandwidth de LTE retiacula plerumque 1.4MHz-20MHz . Cartellatrix aggregatio technology potest 'Splice ' plures carriers in latior Sed, ita augendae in rate. Nam exemplum:
Cat4 sustinet ad II carrier aggregationes (totalis Sed 40mhz );
Cat6 sustinet II carrier aggregationes (totalis Sed 40mhz ), sed ex introductio 256QAM , quod rate excedit quod de Cat4;
CAT12 sustinet III carrier aggregationes (totalis Sed 60mhz ), Achieving altius perficientur in combination cum 256QAM.
III. Mimo configuratione: Spatium 'parallel Transmissus ' Capability
Mimo (multiple input plures output) realizes locorum multiplexing per transmittendi et accepto notitia per plures antennas eodem tempore. Et Mimo configuratione de LTE terminals repraesentatur per 'numerus transmittendi antennas × numerum accepto antennas ';
Cat1 / cat4 plerumque firmamentum II × II MIMO (II transmittendi antennas + II accepto antennas);
Cat6 et supra potest sustinere IV × IV Mimo , quam theoretically duplicat notitia rate.
III. Technical parametri et applicationem missionibus de amet LTE Categories Categories
Omnes feles genera effectum magnam scale commercialization. Currently, in sequentibus genera sunt maxime late solebat, se correspondentes diversis sem elit:
I. Cat1: et 'oeconomica et practica exemplar ' enim Internet de rebus
Core parametri : downlink rate 10Mbps , uplink rate 5Mbps ; Supports 16QAM / 64QAM modulation: II × II Mimo , et non support Papamer aggregatio.
Technical features : Minimum sumptus, humilis potentia consummatio (standby tempus potest pervenire aliquot annos), potest esse cum simplex hardware, idoneam ad humilis-rate et longa-nexum.
Typical Applications : Smart aqua metris / Gas metris (tantum Tens KB de notitia opus per mensis), participatur bicycles (positioning et status renuntiationes), wearable cogitationes (Cordis rate / positione data transmissione).
II. CAT4: Quod 'principalis vi ' de dolor-gradus cogitationes
Core parametri : downlink rate 150Mbps , uplink rate 50Mbps ; Sustinet 64QAM modulation: II × II Mimo , usque ad II carrier aggregationes ( 40mhz ).
Technical Features : Statera Rate et pretium, potest obviam necessitatibus maxime dolor-gradus missionibus, et est amet choice pro 4G iter itineris et ingressum-gradu mobile phones.
Typical Applications : Home 4g iter ( eg Lb-link CPE450ax ), medium-ut-low-finem Smartphones, car navigation (realis-vicis negotiationis et online music).
III. Cat6: Quod 'perficientur representative ' pro summus celeritate mobile missionibus
Core parametri : downlink rate 300mbps , uplink rate 50Mbps ; Introduces 256QAM Modulation (DownLink), II × II Mimo , II Papamer aggregationes ( 40mhz ).
Technical Features : adoptat 256QAM ad primum in downlink, incrementum data 'packaging efficientiam ' per XXXIII%, idoneam ad missiones sensitivo ad downlink rates.
Typical Applications : High- 4G Routers (Enterprise-Level), 4k Live Armis Equipment (velit Event Video Live Broadcast), in-vehiculum Ago video playback).
IV. Cat12: et 'summus celeritas benchmark ' pro industriae-gradu
Core parametri : downlink rate 600mbps , uplink rate 100Mbps ; Sustinet 256QAM modulation, IV × IV Mimo , III carrier aggregationes ( 60mhz ).
Technical Features : Multi-Carrier Aggregatio + High-Ordinis Mimo, Balancing Rate et Stabilitatem, testimonii Industrial-Grade summus Bandwidth requisita.
Typical Applications : Industrial Cras (Real-Time Backhaul of Multi-Channel 4k cameras), Telemedicine (High-Definitio Chirurgicam Video Transmission), Enterprise dedicated linea Tergum (repositoque aliquod optical fibra).
IV. De necessitudine inter Categories et user experientia: Key ultra rate
Ordinarius users potest cogitare quod 'in altiorem cat planum, in melius ', sed ipsa experientia necessitates ad combined cum missionibus:
Rate est non solum vexillum : exempli gratia, cat4 scriptor 150mbps potest iam occursum necessitates 4k videos (requiring 25Mbps ), Video Conferentias (requiring 4MBPS ), etc. caeci Persequi CAT6 / Cat12 et proventus Fabrica sumptus et virtute consummatio.
'Matching ' inter network et terminatio : terminatio est scriptor cat gradu necessitates ad par technologiae sustinentur per operator scriptor network. Exempli gratia, si operator non deployed carrier aggregatio, Cat6 terminals non consequi a rate of 300mbps.
Statera inter virtutem consummatio et missionibus , altior cattus gradu maiorem virtutem consummatio terminatio chip. Ideo noot cogitationes (ut dolor metris) sunt magis idoneam ad Cat1 (humilis potentia consummatio) quam cat4 / Cat6.
V. Evolution Logica Categories Categories: ex 'celeritas competition ' ad 'sem sem '
Definitio Categories per 3GPP reflects ad Evolutionem ideam de 4g technology:
Early scaena (2008-2012) focused in rate emendationem ex cat1 ad Cat4 , occurrens ad 'ex VULNUS ' mobile Broadband necessitatibus;
Medio scaena (2013-2016) : introduced carrier aggregatio et summus ordinis modulatum (ut 256QAM pro Cat6 ), per rate bottleneck;
Postea scaena (2017-2020) : segmentios missionibus, launching humilis-potentia cattus-M1 / NB-IOT (rate tantum decem kbps) pro Internet et de rebus et altus- performance .
Hoc 'lata-spectro coverage ' PRAEGRESSUS enables 4g LTE ad Support utrumque Micro-notitia Transmission of Smart Watches et summus celeritate necessitatibus 4k vivet broadcasts technologies in historia.
Conclusio: intellectus Categories eligere ius 4g fabrica
LTE Categories sunt 'Technical id cards ' de terminatio communicationis elit. Non solum filum numeri sed duce ad matching cogitationes cum missionibus. Nam Ordinarius users, cat4 potest iam dignum maxime necessitates ut domum suam et officium; Enterprises aut speciale missionibus, Cat6 et supra potest electus secundum rate, virtute consummatio, et sumptus.
Cum popularis ex 5g , lte categories erit adhuc ludere a diu terminus partes in Internet rerum, coverage in remotis locis et aliis agris. Intelligendo eius technica logica potest non solum auxilium nobis eligere magis idoneam cogitationes, sed etiam evidenter videre progressionem context de mobile communicationis technology 'ex generali ad segmented '.
