Nei RF mafirita ari kuwedzera kukosha?
Kukura nekukurumidza kwenharembozha isina waya data uye 4G LTE network kwakonzera kudiwa kuri kukura kwemabhendi matsva uye kune anotakura aggregation kusanganisa mabhendi kuti agare isina waya traffic. Iyo 3G network inoshandisa chete mabhendi mashanu, uye LTE network ikozvino inoshandisa anopfuura 40 mabhendi, uye nekuuya kwe5G, nhamba yemabhandi ichawedzera kuwedzera.
Zvishandiso zvakabatana zvinotumira masaini mumabhendi akawanda: cellular, Wi-Fi, Bluetooth, uye GPS, uku uchidzivirira kukanganiswa. Isu tinogona kubva tafunga nezvemafoni efoni, shark zvimbi zvakaiswa pamusoro pemota, cellular base station, radar uye masisitimu ekutaurirana, uye maindasitiri, sainzi, kana zvekurapa zvikumbiro zvakabatana neInternet yezvinhu (IoT). Panguva ino, sefa inodiwa kuti ibude.
A smartphone isina sefa chidhinha
Kufanana nema antennas, mafirita ari kuwedzera kukosha chikamu che networking mixers. Chishandiso chinogashira ma frequency akasiyana, uye sefa inobvumira frequency yaidiwa kuti ipfuure uku ichidzvanya frequency isingadikanwi. Mune mamwe mazwi, sefa yakafanana neGandalf munaJohn Ronald Ryall Tolkien's "Ishe weRings": "Iwe haungapfuuri!" "Midziyo yemazuva ano inowanzoiswa mafirita makumi matatu kusvika makumi mana kuti isakanganiswa. Mamiriro ezvinhu aya achange akaoma zvikuru sezvo chizvarwa chinotevera chemafoni emhando yepamusoro chinoda mamwe mafirita.
Sefa magadzirirwo matambudziko
Mafirita chishandiso chakakosha cheRF dhizaini mainjiniya, asi ivo vanosanganawo nematambudziko mazhinji. Kutanga, kuita kwesefa kunosiyana nekupisa. Mafirita ari mumidziyo yakasiyana-siyana nhasi anogona kumira paavhareji tembiricha ye60 madhigirii celsius (140 madhigirii Fahrenheit) kana kupfuura, nepo mafirita emukati anogona kumira paavhareji tembiricha ye25 madhigirii Celsius (77 madhigirii Fahrenheit) uye kunyange tembiricha yakakwira yezvimbi zveshaki kana mafirita akaiswa mukati. denga. Iyo yakakwira tembiricha yefirita, zvakanyanya kuoma kusefa imwe frequency, uye zvakanyanya mukana wekuti chiratidzo "chichakukurwa" kune iri padyo bhendi.
Kubata tembiricha yekudonha kwakakosha nekuti mazhinji emabhendi achangopihwa ari padyo nemabhendi aripo. Panguva imwecheteyo, carrier aggregation (CA) iri kukura nekukurumidza, nevanopa masevhisi enhare vachibatanidza kusvika kumatanho mashanu ekutakura kuratidza mashandiro etiweki, uko kusefa chaiko kunodiwa.
Kugadzirisa nyaya dzetembiricha, indasitiri yeRF iri kuvandudza tekinoroji yakaderera uye yekudhiraivha-isina mafirita. Surface Sonic (SAW) uye Body Sound Wave (BAW) mafirita anochengetedza yakakwira dhigirii yekugadzikana kana tembiricha yachinja, ichisangana nezvinodiwa zvekushanda kwemidziyo iri kubuda.
Sezvambotaurwa pamusoro apa, chizvarwa chinotevera chemafoni epamusoro-soro anodawo kuve akashongedzerwa nemamwe mafirita. Kufanana nezvimwe zvese zvikamu zve rf, kune nzvimbo diki kwazvo yemafirita. Mainjiniya anofanirwa kukwanisa kubatanidza mafirita akawanda munzvimbo diki dzekuita kwepamusoro.
Duplexers, triplexers, cuadruplexers uye hexaplexers vakaungana vanonzi multiplexers. Multiplexers inobatanidza mafirita akawanda mumudziyo mumwe chete kubatsira vagadziri kuchengetedza nzvimbo, kurerutsa dhizaini, kusangana nekuita zvinodiwa, uye kudzivirira kukanganisa.
Munharaunda yanhasi yenharembozha, huwandu hwemabhendi anodiwa pamudziyo hunokatyamadza, uye nekuuya kweiyo 5G nguva, maitiro aya ari kuzotowedzera. Nepo kutsigira mabhendi ese kunogona kukonzera matambudziko ekukanganisa, dambudziko rinogona kugadziriswa nesefa. Pasina mafirita, network haishande.
