Izindaba - Iyini uhlelo lwe-antenna olusatshalaliswe (DAS)

1. Iyini uhlelo lwe-antenna olusatshalaliswe?

Uhlelo lwe-Antenna oluSabalalisiwe (i-DAS), olwaziwa nangokuthiisikhuthazi sesignali yeselulauhlelo noma uhlelo lokuthuthukisa isignali yeselula, lusetshenziselwa ukukhulisa isignali yocingo noma ezinye izignali ezingenantambo. I-DAS ithuthukisa izignali zeselula ngaphakathi ngokusebenzisa izingxenye ezintathu eziyinhloko: umthombo wesignali, i-repeater yesignali, kanye namayunithi okusabalalisa ngaphakathi. Iletha isignali yeselula kusuka esiteshini esiyisisekelo noma endaweni yangaphandle iye endaweni yangaphakathi.

2. Kungani sidinga uhlelo lwe-antenna olusatshalaliswe?

Izimpawu zeselula ezikhishwa yiziteshi eziyisisekelo zabahlinzeki bezokuxhumana beselula zivame ukuvinjelwa yizakhiwo, amahlathi, izintaba, nezinye izithiyo, okuholela ezindaweni ezibuthakathaka zezibonakaliso nezindawo ezifile. Ngaphezu kwalokho, ukuvela kobuchwepheshe bokuxhumana kusuka ku-2G kuya ku-5G kuye kwathuthukisa kakhulu impilo yabantu. Ngesizukulwane ngasinye sobuchwepheshe bokuxhumana, amazinga okudlulisa idatha akhuphuke kakhulu. Kodwa-ke, intuthuko ngayinye kubuchwepheshe bokuxhumana iletha izinga elithile lokuncipha kokusabalala kwezibonakaliso, okunqunywa yimithetho yemvelo.

Ngokwesibonelo:

Izici ze-Spectrum:
I-5G: Ngokuyinhloko isebenzisa ama-band anemvamisa ephezulu (amagagasi e-millimeter), ahlinzeka nge-bandwidth ephezulu kanye nesivinini kodwa anendawo encane yokumboza kanye nokungena okubuthakathaka.
I-4G: Isebenzisa amabhendi emvamisa aphansi kakhulu, inikeza ukumbozwa okukhulu kanye nokungena okunamandla.

Kwezinye izimo zebhendi evame kakhulu, inani leziteshi zesisekelo ze-5G lingaba ngokuphindwe kahlanu kuneziteshi zesisekelo ze-4G.

Ngakho-ke,izakhiwo ezinkulu zesimanje noma izindlu ezingaphansi ngokuvamile zidinga i-DAS ukuze zidlulisele izimpawu zeselula.

Ukumbozwa Okuthuthukisiwe: Kuthuthukisa amandla esignali ezindaweni ezibuthakathaka noma ezingenakho ukumbozwa.
Ukuphathwa Kwamandla: Isekela inani elikhulu labasebenzisi ngokusabalalisa umthwalo kuma-node amaningi e-antenna.
Ukuphazamiseka Okuncishisiwe: Ngokusebenzisa ama-antenna amaningi anamandla aphansi, i-DAS inciphisa ukuphazamiseka uma kuqhathaniswa ne-antenna eyodwa enamandla aphezulu.
Ukwanda: Kungalinganiswa ukuze kuhlanganiswe izakhiwo ezincane kuya kumakhampasi amakhulu.

4. Yiziphi Izinkinga Ezingaxazululwa Uhlelo lwe-DAS?

Isisekelo Selabhulali Esihlakaniphile kuhlelo lwe-DAS

I-DAS ivame ukusetshenziswa ezindaweni ezinkulu, ezakhiweni zezentengiselwano, ezibhedlela, ezindaweni zokuthutha, nasezindaweni zangaphandle lapho ukumbozwa kwesignali yeselula engenantambo okuhlala njalo nokuthembekile kubalulekile. Iphinde idlulise futhi ikhulise amabhendi esignali yeselula asetshenziswa yizinkampani ezahlukene ukuze kuhlangatshezwane namadivayisi amaningi.

Njengoba ubuchwepheshe bokuxhumana beselula besizukulwane sesihlanu (5G) bukhula, isidingo sokusetshenziswa kwe-DAS siyanda ngenxa yokungena okungekuhle kanye nokuthambekela okukhulu ekuphazamisekeni kwamagagasi e-5G millimeter (mmWave) ekudlulisweni kwendawo.

Ukufaka i-DAS ezakhiweni zamahhovisi, ezibhedlela, ezikoleni, ezindaweni zokuthenga, nasezinkundleni zemidlalo kungahlinzeka ngesembozo senethiwekhi ye-5G esheshayo, ebambezelekile futhi esekela inani elikhulu lamadivayisi eselula. Lokhu kwenza izinsizakalo ezihlobene ne-5G IoT kanye ne-telemedicine.

5. Iphrofayili ye-Lintratek kanye ne-DAS

I-Lintratekkubeumenzi ochwephesheyokuxhumana ngeselula ngemishini ehlanganisa i-R&D, ukukhiqizwa, kanye nokuthengisa iminyaka eyi-12. Imikhiqizo yokumbozwa kwesignali emkhakheni wokuxhumana ngeselula: izikhulisi zesignali zefoni ephathekayo, ama-antenna, ama-power splitter, ama-couplers, njll.

Uhlelo lwe-DAS lwe-Lintratek

I-Lintratek'sUhlelo lwe-Antenna Olusatshalaliswe (i-DAS)ikakhulukazi ithembele kuma-repeater e-fiber optic. Lolu hlelo luqinisekisaukudluliswa kwebanga elideyezimpawu zeselula ezingaphezu kwamakhilomitha angu-30 futhi isekela ukwenza ngokwezifiso amabhendi ahlukahlukene emvamisa yeselula. I-DAS ye-Lintratek ingenziwa ngokwezifiso ngezinhlelo zokusebenza ezahlukene ngokusekelwe ezidingweni zamakhasimende, kufaka phakathi izakhiwo zezentengiselwano, izindawo zokupaka ezingaphansi komhlaba, izindawo zomphakathi, amafektri, izindawo ezikude, nokuningi. Ngezansi kunezibonelo ezithile zokuqaliswa kwe-DAS ye-Lintratek noma uhlelo lokukhulisa isignali yeselula.
