I-HSPA ne-HSPA + Thuthukisa Isevisi ye-Intanethi kuma-3G Amakhalekhukhwini
Amanethiwekhi we-3G awasekho esheshayo atholakalayo, kodwa asetshenziswa abantu abaningi kanye nabahlinzeki bensizakalo abaningi. Ukufinyelela kwe-High-Speed Packet kuyinto evamile yokuxhumana kwenethiwekhi okungenantambo kumndeni we-3G. Umndeni we-HSPA wezivumelwano zenethiwekhi uhlanganisa i-HSDPA ne-HSUPA. Inguqulo ethuthukisiwe ye-HSPA ebizwa ngokuthi i-HSPA + yaqhubeka nokuguqula lesi simiso.
HSDPA
I-HSPA isebenzisa i- High-Speed Downlink Phakethe yokufinyelela yePakethe yokuthola ithrekhi yokulandwa. I-HSDPA isekela amazinga e-data aphakeme kakhulu phakathi kuka-1.8 Mbps no-14.4 Mbps (uma kuqhathaniswa ne-384 Kbps isilinganiso esiphezulu se-3G yangempela). Uma kuqalisiwe, inikeze ukuthuthukiswa okusheshayo okusheshayo phezu kuka-3G omdala ojwayelekile ukuthi amanethiwekhi ase-HSDPA asekelwe ku-3.5G noma Super-3G.
Isimiso se-HSDPA sagunyazwa ngo-2002. Sisebenzisa ubuchwepheshe be-AM obushintsha ngokuguquguqukayo ukuthunyelwa ngokusho kwenethiwekhi jikelele.
HSUPA
Ukufinyelela kwe-High-Speed Uplink Packet inikeza ukwanda okusheshayo kokulayishwa kwedatha yeselula kumanethiwekhi e-3G afana ne-HSDPA yokulandwa. I-HSUPA isekela amazinga wedatha kuze kufike ku 5.7 Mbps. Ngokuklama, i-HSUPA ayinikezi amazinga afanayo yedatha njenge-HSPDA, ngoba abahlinzeki banikezela iningi lamandla abo wenethiwekhi yeselula ye-downlink ukufanisa amaphethini wokusetshenziswa kwabasebenzisi befoni.
I-HSUPA yathulwa ngo-2004, ngemuva kwe-HSDPA. Amasevisi ekugcineni asekela bobabili babaziwa ngokuthi amanethiwekhi we-HSPA.
I-HSPA ne-HSPA & # 43; kuma-3G Amanethiwekhi
Inguqulo ephakanyisiwe ye-HSPA ebizwa nge-HSPA + noma i-Evolved HSPA yasungulwa futhi isetshenziselwa abathwali abaningi ukusekela kangcono ukukhula okukhulu kwezinsizakalo ezisezingeni eliphezulu ze- broadband . I-HSPA + yiyona protocol ye-3G esheshayo, isekela amanani wedatha angu-42, 84 futhi ngezinye izikhathi ama-168 Mbps okulandwayo kuze kufike ku-22 Mbps ukuze ulayishwe.
Lapho ubuchwepheshe buqaliswa kuqala, abasebenzisi kumanethiwekhi athile ka-3G babika izinkinga ngokuxhumana kwabo kweselula kuvame ukushintsha phakathi kwe-HSPA nezindlela ezidala ze-3G. Ukuthembeka kwenethiwekhi ye-HSPA no-HSPA + akusona inkinga. Ngaphandle kwama-glitches wezobuchwepheshe, abasebenzisi bezinethiwekhi ze-3G akudingeki ukuba bahlele ngokukhethekile amadivayisi wabo ukusebenzisa i-HSPA noma i-HSPA + lapho umhlinzeki wabo esekela ngokufanele. Njengamanye ama-protocol asemaselula, inani lamanani langempela umuntu angakwazi ukulifinyelela efonini labo nge-HSPA noma i-HSPA + liphansi kakhulu kunama-maximum alinganisiwe ahlongozwe kumacomps embonini. Amazinga wokulanda ama-HSPA kumanethiwekhi amanethiwekhi ayi-10 Mbps noma aphansi nge-HSPA + futhi aphansi njenge-1 Mbps ye-HSPA.
I-HSPA & # 43; I-Versus LTE
Amazinga aphezulu kakhulu wedatha we-HSPA + abangela abanye embonini ukuba bayibheke njengobuchwepheshe be-4G. Ngenkathi i-HSPA + inikeza ezinye izinzuzo ezifanayo ngombono womsebenzisi, ochwepheshe bayavuma ukuthi ubuchwepheshe obuphezulu kakhulu be- LTE bufaneleka ngokucacile njenge-4G kanti i-HSPA + ayikho. Isici esiqakathekile sokuhlukanisa amanethiwekhi amaningi yi- latency yenethiwekhi ephansi ngokuphawulekayo okuxhunyanwa yi-LTE phezu kwe-HSPA +.
