I-6GHz Spectrum, Ikusasa le-5G

Ukwabiwa kwe-6GHz Spectrum Kuqediwe

I-WRC-23 (World Radiocommunication Conference 2023) isanda kuphothulwa e-Dubai, ehlelwe yi-International Telecommunication Union (ITU), ehlose ukuxhumanisa ukusetshenziswa kwe-spectrum emhlabeni jikelele.

Ubunikazi be-spectrum ye-6GHz kwakuyindawo okugxilwe kuyo ukunakwa komhlaba wonke.

Ingqungquthela inqume: Ukwaba ibhendi engu-6.425-7.125GHz (700MHz bandwidth) kumasevisi eselula, ikakhulukazi ukuxhumana kweselula kwe-5G.

Iyini i-6GHz?

I-6GHz ibhekisela ebangeni le-spectrum ukusuka ku-5.925GHz ukuya ku-7.125GHz, ne-bandwidth efika ku-1.2GHz. Ngaphambilini, i-spectra eyabelwe i-mid-to-low frequency yezokuxhumana kwamaselula kakade yayinokusetshenziswa okunikelwe, nokusetshenziswa kuphela kwe-spectrum ye-6GHz okusele kungacacile. Umkhawulo wokuqala ochaziwe ophezulu we-Sub-6GHz we-5G wawungu-6GHz, ngenhla okuyi-mmWave. Ngesandiso esilindelwe somjikelezo wokuphila we-5G kanye nethemba elibi lezentengiselwano le-mmWave, ukuhlanganisa ngokusemthethweni i-6GHz kubalulekile esigabeni esilandelayo sokuthuthuka se-5G.

I-3GPP isivele yalinganisa ingxenye engaphezulu ye-6GHz, ikakhulukazi i-6.425-7.125MHz noma i-700MHz, ku-Release 17, eyaziwa nangokuthi i-U6G negama lebhendi elithi n104.

I-Wi-Fi nayo ibilwela i-6GHz. Nge-Wi-Fi 6E, i-6GHz ifakiwe kokujwayelekile. Njengoba kuboniswe ngezansi, nge-6GHz, amabhendi e-Wi-Fi azonwebeka esuka ku-600MHz ku-2.4GHz kanye no-5GHz aye ku-1.8GHz, futhi i-6GHz izosekela kufikela ku-320MHz umkhawulokudonsa wenkampani yenethiwekhi eyodwa ku-Wi-Fi.

Ngokombiko we-Wi-Fi Alliance, i-Wi-Fi okwamanje inikeza amandla amaningi enethiwekhi, okwenza i-6GHz ikusasa le-Wi-Fi. Izimfuno ezivela kwezokuxhumana zeselula ze-6GHz azinangqondo njengoba i-spectrum eminingi ihlala ingasetshenziswa.

Eminyakeni yamuva nje, kube nemibono emithathu ngobunikazi be-6GHz: Okokuqala, yabele ngokugcwele i-Wi-Fi. Okwesibili, yabele ngokugcwele kwezokuxhumana ngeselula (5G). Okwesithathu, yihlukanise ngokulinganayo phakathi kokubili.

Njengoba kubonakala kuwebhusayithi ye-Wi-Fi Alliance, amazwe aseMelika anikeze kakhulu i-6GHz yonke ku-Wi-Fi, kuyilapho iYurophu incike ekwabeni ingxenye ephansi ku-Wi-Fi. Ngokwemvelo, ingxenye engaphezulu esele iya ku-5G.

Isinqumo se-WRC-23 singabhekwa njengesiqiniseko sokuvumelana okumisiwe, ukuzuza ukunqoba phakathi kwe-5G ne-Wi-Fi ngokuncintisana phakathi nokuyekethisa.

Yize lesi sinqumo singase singayithinti imakethe yase-US, asivimbeli i-6GHz ekubeni ibhendi yomhlaba wonke. Ngaphezu kwalokho, imvamisa ephansi uma kuqhathaniswa yaleli bhendi yenza ukuzuza ukumbozwa kwangaphandle kufane no-3.5GHz kungabi nzima kakhulu. I-5G izongenisa igagasi lesibili lokuphakama kokwakhiwa.

Ngokwesibikezelo se-GSMA, leli gagasi elilandelayo lokwakhiwa kwe-5G lizoqala ngo-2025, limaka ingxenye yesibili ye-5G: 5G-A. Sibheke ngabomvu izimanga ezizolethwa yi-5G-A.

I-Concept Microwave ingumkhiqizi ochwepheshe wezingxenye ze-5G/6G RF e-China, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/i-band stop filter, i-duplexer, isihlukanisi samandla kanye ne-coupler eqondisayo. Zonke zingenziwa ngezifiso ngokuya ngezidingo zakho.
