     Kodi mukudziwa ma frequency omwe amagwiritsidwa ntchito kwambiri polankhula za mafoni?Lero kuti aliyense awonjezere chidziwitso.

Kuyambira pamene makampani olumikizirana ku China akukula, pang'onopang'ono pakhala mgwirizano wa 2G/3G/4G/5G, kutumiza kwa chizindikiro cha kulankhulana pafoni kumafalikira kudzera mu ma frequency enaake, ndipo ma frequency atatu akuluakulu ali ndi ma frequency osiyanasiyana ndipo miyezo ya netiweki imasiyana, zomwe zimapangitsa kuti mafoni atatu akuluakulu asakhale ofanana, ndiye kuti ma frequency atatu omwe amagwiritsidwa ntchito nthawi zambiri ndi chiyani? Kodi kuzindikiritsa ma frequency kumatanthauza chiyani?

Mafupipafupi a zizindikiro za mafoni a m'manja a ogwira ntchito atatu akuluakulu ku China nthawi zambiri amakhala motere (LintratekChobwerezabwereza cha 4G cha m'manjaikhoza kusinthidwa malinga ndi magulu afupipafupi a mayiko ndi madera ena):

1, China Mobile: 885-909 (uplink), 930-954Mhz (downlink);

2, China Unicom: 909-915 (uplink), 954-960Mhz (downlink);

3, China Telecom: 825-835 (uplink), 870-880Mhz (downlink).

Kufunika kwa chizindikiro cha foni yam'manja kutengera kuchuluka kwa ma frequency:

Chizindikiro Chozindikiritsa G:
Dzina lonse la G ndi GPRS, lomwe ndi la netiweki ya 2.5G ndipo ndi muyezo wa netiweki kwa ogwiritsa ntchito mafoni a m'manja a GSM. Kuyambira pachiyambi cha GRPS, mafoni amatha kugwiritsa ntchito intaneti mwalamulo;

Kuzindikiritsa chizindikiro E
Dzina lonse la E ndi EDGE, chidule cha ukadaulo wa GSM evolution, womwe ndi ukadaulo wosinthira kuchokera ku GSM kupita ku 3G. Liwiro lake ndi lachangu pang'ono kuposa GPRS, yomwe ndi ya netiweki ya 2.75G. E ndiye njira yotumizira ma netiweki opanda zingwe pafoni m'zaka zomwe mafoni anzeru adangotuluka kumene.

Kuzindikiritsa chizindikiro 3G

3G imasonyeza netiweki yodziwika bwino ya 3G, yomwe ili ndi kuchuluka kwa kutumiza deta kuposa E. Mu nthawi ya 3G, ndi bandwidth yayikulu komanso kutumiza kokhazikika, mapulogalamu a intaneti yam'manja adayamba kuyambira nthawi imeneyo;

Kuzindikiritsa chizindikiro H
H+ ndi mtundu wowonjezeredwa wa HSDPA HSPA+, ndi wa netiweki ya 3.75G, imatha kufika pa liwiro lalikulu la 42Mbps downlink, liwiro la netiweki lawongoleredwanso kwambiri;

Kuzindikira chizindikiro4G
4G ndi netiweki yomwe anthu ambiri akugwiritsa ntchito pakadali pano, ndipo ndi yochepa kwambiri poyerekeza ndi ukadaulo wolumikizirana pafoni wa m'badwo wachinayi. Pakutumiza mawu, makanema ndi zithunzi, liwiro lapita patsogolo kwambiri, ndipo liwiro lotumizira mauthenga likhoza kufika pa 100Mbps;

Kuzindikira chizindikiroHD

HD ndi chizindikiro cha mafoni apamwamba, kutanthauza VoLTE, yomwe imatchedwanso mawu apamwamba, omwe ndi netiweki ya 4G. Ntchito yayikulu ya VolTE ndikuti mafoni a mawu sagwiritsidwanso ntchito ndi ma netiweki a 2G /3G, ndipo ma netiweki a 4G amagwiritsidwa ntchito kutumiza deta ya mawu, kuthandizira ukadaulo wapamwamba wa ma code a chilankhulo, khalidwe la mafoni limakula kwambiri, komanso kuthandizira kugwiritsa ntchito intaneti mukamalankhula.

Ukadaulo wa Lintratek wa 4g wobwerezabwereza mafoni umaphimba mayiko ndi madera 155 padziko lonse lapansi, umatha kupatsa makasitomala ntchito zaukadaulo zomwe zimathandizira ogwiritsa ntchito kuthetsa zosowa za chizindikiro cholumikizirana,Lintratekyadzipereka kukhala mtsogoleri wa makampani ofooka a mlatho wa chizindikiro, kuti dziko lonse lisakhale ndi malo osawoneka bwino, kuti aliyense akhale wopanda zopinga zolumikizirana!
