I-Spectrum ye-6GHz, Ikusasa le-5G

Ukwabiwa kwe-Spectrum ye-6GHz Kuqediwe

I-WRC-23 (Ingqungquthela Yokuxhumana Ngomsakazo Yomhlaba Ka-2023) isanda kuphothulwa eDubai, ihlelwe yi-International Telecommunication Union (ITU), ihlose ukuhlanganisa ukusetshenziswa kwe-spectrum yomhlaba wonke.

Ubunikazi be-spectrum ye-6GHz kwakuyiyona nto eyayigxile ekunakweni komhlaba wonke.

Ingqungquthela inqume ukuthi: Ukwabela ibhendi engu-6.425-7.125GHz (umkhawulokudonsa ongu-700MHz) yezinsizakalo zeselula, ikakhulukazi ezokuxhumana zeselula ze-5G.

Kuyini i-6GHz?

I-6GHz ibhekisela kububanzi be-spectrum kusukela ku-5.925GHz kuya ku-7.125GHz, kanye ne-bandwidth efika ku-1.2GHz. Ngaphambilini, ama-spectra e-frequency aphakathi kuya kwephansi abelwe ukuxhumana kweselula kakade ayenokusetshenziswa okuzinikele, kanti ukusetshenziswa kwe-spectrum ye-6GHz kuphela okwakungakacaci. Umkhawulo wokuqala ophezulu ochaziwe we-Sub-6GHz we-5G wawuyi-6GHz, ngaphezulu kwawo yi-mmWave. Njengoba kulindeleke ukwanda komjikelezo wokuphila we-5G kanye namathuba amabi okuhweba e-mmWave, ukufaka ngokusemthethweni i-6GHz kubalulekile esigabeni esilandelayo sentuthuko ye-5G.

I-3GPP isivele ilinganise ingxenye ephezulu ye-6GHz, ikakhulukazi i-6.425-7.125MHz noma i-700MHz, ku-Release 17, eyaziwa nangokuthi i-U6G enegama lebhendi yemvamisa n104.

I-Wi-Fi ibilokhu incintisana nge-6GHz. Nge-Wi-Fi 6E, i-6GHz ifakiwe ku-standard. Njengoba kuboniswe ngezansi, nge-6GHz, ama-Wi-Fi band azokhula kusuka ku-600MHz ku-2.4GHz kanye ne-5GHz kuya ku-1.8GHz, kanti i-6GHz izosekela i-bandwidth efika ku-320MHz yenkampani eyodwa ku-Wi-Fi.

Ngokusho kombiko we-Wi-Fi Alliance, i-Wi-Fi okwamanje inikeza iningi lamandla enethiwekhi, okwenza i-6GHz ibe yikusasa le-Wi-Fi. Izidingo zokuxhumana kweselula ze-6GHz azinangqondo njengoba i-spectrum eningi isasetshenziswa.

Eminyakeni yamuva nje, kube nemibono emithathu ngobunikazi be-6GHz: Okokuqala, ukwabela ngokugcwele i-Wi-Fi. Okwesibili, ukwabela ngokugcwele ukuxhumana kweselula (5G). Okwesithathu, ukwabela ngokulinganayo phakathi kwalokhu okubili.

Njengoba kungabonakala kuwebhusayithi ye-Wi-Fi Alliance, amazwe aseMelika anikeze kakhulu i-6GHz yonke kwi-Wi-Fi, kuyilapho iYurophu ithambekele ekwabeleni ingxenye engezansi kwi-Wi-Fi. Ngokwemvelo, ingxenye ephezulu esele iya ku-5G.

Isinqumo se-WRC-23 singabhekwa njengesiqiniseko sesivumelwano esikhona, esizuzisa bonke ngokuncintisana kanye nokuvumelana.

Nakuba lesi sinqumo singase singayithinti imakethe yase-US, asivimbeli i-6GHz ekubeni yibhendi yomhlaba wonke. Ngaphezu kwalokho, imvamisa ephansi yale bhendi yenza ukufeza ukumbozwa kwangaphandle kufane ne-3.5GHz kungabi nzima kakhulu. I-5G izoletha igagasi lesibili lesikhathi sokwakhiwa.

Ngokusho kwesibikezelo se-GSMA, leli gagasi elilandelayo lokwakhiwa kwe-5G lizoqala ngo-2025, okuzophawula ingxenye yesibili ye-5G: 5G-A. Silangazelela izimanga ezizolethwa yi-5G-A.

I-Concept Microwave ingumkhiqizi ochwepheshe wezingxenye ze-5G/6G RF eShayina, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/band stop, i-duplexer, i-Power divider kanye ne-directional coupler. Zonke zingenziwa ngokwezifiso ngokwezidingo zakho.
