HSPA kunye ne-HSPA + Ukuphucula iNkonzo ye-Intanethi kwii-3G zefoni
Iinqununu ze-3G azikho ezona zikhawulezileyo, kodwa zisasetyenziswa ngabantu abaninzi kunye nabanikezeli benkonzo yeselula. UkuPhezuluka kwePakethe yokuPhezulu kufumaneka umgangatho wenxibelelwano lonxibelelwano lwentambo kwi-3G. Intsapho ye-HSPA yeenkqubo zokunxibelelanisa i- HSDPA kunye ne-HSUPA. Inguqu ephuculweyo ye-HSPA ebizwa ngokuthi i-HSPA + yaqhubeka iguqule le miselo.
HSDPA
I-HSPA isebenzisa i- High-speed Downlink Packet Access protocol yokukhuphela i-traffic traffic. I-HSDPA isekela amaxabiso e-data ephezulu phakathi kwe-1.8 Mbps kunye no-14.4 Mbps (xa kuthelekiswa ne-384 Kbps izinga eliphezulu le-3G yokuqala). Xa kuqalisiwe, kwanikezela ukuphuculwa okukhawulezayo kwezantya kwi-3G eziqhelekileyo eziqhelekileyo ukuba ii-HSDPA-based networks zithunyelwe njenge-3.5G okanye Super-3G.
Umgangatho we-HSDPA walungiswa ngo-2002. Usebenzisa i-AM ubuchwepheshe obulungiselela ngokusasazwa ngokuthumela umthwalo wonxibelelwano jikelele.
HSUPA
Ukufikelela kwi-High-Speed Uplink Packet inikezela ukunyuka kwekhawulezileyo zokulayishwa kwedatha yeselula kwiingcingo ze-3G ezifana ne-HSDPA yokulandwa. I-HSUPA isekela amaxabiso eedatha ukuya kuma-5.7 Mbps. Ngoyilo, i-HSUPA ayinikeli ixabiso leedata elifanayo njenge-HSPDA, kuba ababoneleli banikezela ubuninzi benethiwekhi yabo yesetelki yamanqanaba okuhlalisa ukulandelana nemilinganiselo yokusetyenziswa yabasebenzisi beefowuni.
I-HSUPA yaziswa ngo-2004, emva kwe-HSDPA. IiNethwekhi ekugqibeleni zisekela zombini zaziwa ngokuba yi-HSPA amanethiwekhi.
HSPA kunye ne-HSPA & # 43; kwi 3G Networks
Inguqu ephuculweyo ye-HSPA ebizwa ngokuthi i-HSPA + okanye i-Evolved HSPA yaphuhliswa kwaye isetyenziswe ngabathwali abaninzi ukuxhasa kangcono ukukhula okukhulu kweenkonzo zesebhanti ezihamba phambili . I-HSPA + yiyona ndlela yokukhawuleza ye-3G, ixhasa amaxabiso e-42, 84 ngamanye amaxesha kunye namaxesha angama-168 Mbps ukulandwa kunye ne-22 Mbps yokulayishwa.
Xa iteknoloji yaqaliswa kuqala, abasebenzisi kumanethiwekhi athile ka-3G babika imiba kunye nokuxhamla kwabo befowuni bahlala beshintsha phakathi kwe-HSPA kunye neendlela zokuqala ze-3G. Ukuthembeka kwenethiwekhi yeHSPA neHSPA + akuyiyo imbambano. Ngaphandle kweempawu zezobugcisa ezithile, abasebenzisi beenethwekhi ze-3G akudingeki ukuba baqwalasele ngokukodwa iifowuni zabo ukusebenzisa i-HSPA okanye i-HSPA + xa umnikezeli wabo uyayigcina ngokufanelekileyo. Njengamanye ama-protocol asemaselula, iirhafu zangempela zoluntu umntu unokuzifeza kwifowuni kunye ne-HSPA okanye i-HSPA + iphantsi kakhulu kunama-maximum echazwe kumacandelo e-industry. Uhlobo lwe-HSPA ukukhuphela amaxabiso kumanethiwekhi amaninzi ngama-10 Mbps okanye ngaphantsi nge-HSPA + kwaye iphantsi kwe-1 Mbps ye-HSPA.
HSPA & # 43; Verses LTE
Amazinga aphezulu afikelela kwi-HSPA + abangela abanye kwi-shishini ukuba bajonge njengeteknoloji ye-4G. Ngoxa i-HSPA + inikeza ezinye zeenzuzo ezifanayo kumbono womsebenzisi, iingcali ziyavuma ukuba iteknoloji ephezulu yeLTE igqibe ngokufanelekileyo njenge-4G ngelixa i-HSPA + ingenzi. Into ebalulekileyo yokuhlukanisa amanethiwekhi amaninzi i- latency yenethiwekhi ephantsi ngokucacileyo ukuba ukuxhunywa kwe- LTE kunikezela nge-HSPA +.
