He aha mea he 3G kelepona, a pehea aole ia pōmaikaʻi ai mākou

Mākou noho a hele i loko o ke ao nei o ka 'ike kahe, e ōlaʻi i o ka kelepona mau kāhea, mea i mau ma ka oihana a ma ka hale, ma kekahi aoao ai kekahi wāʻalo me ka 3G paʻamau (inoa pōkole no ka' ōlelo Pelekānia. "Ekolu hanauna"). E mai ninau aku ia makou iho: "He aha mea he 3G kelepona?"

Europe alakaʻi i na mea "olelo" i hoakaka ia hae - UMTS, ia ho i kaʻae like hoʻokuʻu ma kahai ma waena o ka maikaʻi ka pono CDMA hae, a me ka nui kapa komo iā ia nui o GSM nā mea kūʻai mai. 3G latike hana i loko o ka UHF huahelu o ma kahi o 2 GHz me kaʻikepili uku o 3.1 Mbit / mau. I ka walaʻauʻana lawelawe no 3G-latike kona külana me ka leo a me nā ikepili palapala. Noho pilikia no ka laulā o nā lawelawe ma ka haʻahaʻa pilikino, ka hoʻomanaʻoʻana i ka mua hae, mai i maopopo i ka 3G kelepona i keia la. I kēia lāʻikepili EYI hoʻolako palapala like me ka hana laulā ma kiʻekiʻe māmā (e-mail, wikiō conferencing, kākou komo i ka 'ikepili i, hooponopono ana o ka kae helu), a me ka pono (lealea, ka nohona latike, ka pāpaho nenoai, online, kūʻai lilo mai kekahi). EYI pākēneka loli aʻe inversely me ka mämä holo o ke kiʻi. Ma ka hihia o ka loaa ana i wahi - 2048 kbit / ka, oiai i ka mämä holo o 3km / h - 348 kbit / s, 120 km / h - 144 kbit / mau. Popular me nā mea hoʻohana malu kona palena Internet lawe lima, i kaumaha ia i ka manawa kūpono no ka paʻa malama uku kona palena komo i ka global i ulanaʻia. He nui i hoihoi i loko o ka nīnau: "Pehea e pono e koho ka Aʻole?" Ka pane a hiki i keia mea puni. Mua, ike ai i ko oe e maona i konaʻaoʻao pale wahi. A laila, Loiloi i pūnaewele holo 'awelika.

E hana i kēia, e hiki no hoi e pono keia mau mea 3G Wi-fi mīkini ala hele. Eʻoluʻolu, e hoailona oukou ia ia no ka ekolu alapine paa 3G Internet: 450, 800, 2100 MHz - wae AYEIE mōkema me ka kukuna.
