HSPA neHSPA + Kuvandudza Indaneti Inhare paMasefoni 3G
3G mitambo haisisiri yakakurumidza kuwanika, asi ichiri kushandiswa nevanhu vakawanda uye vazhinji vanoita basa remagetsi. High-Speed Packet Kutsvaga ndeyomuenzaniso wekutengesa mitambo yenhare mumhuri ye 3G. Mhuri yeHSPA yemitambo yenethiwekhi inosanganisira HSDPA neHSUPA. Shanduro yakasimbiswa yeHSPA inonzi HSPA + yakachinjazve chiyero ichi.
HSDPA
HSPA inoshandisa High-Speed Downlink Packet Access protocol yekutsvaga traffic. HSDPA inotsigira zvakanyanyisa kudarika kwedhadha yepamusoro pakati pe 1.8 Mbps uye 14.4 Mbps (ichienzaniswa ne 384 Kbps yakawanda yepamusoro ye 3G yepakutanga). Paakaiswa, yakapa kuwedzera kwakakurumidza kukurumidza pane 3G yakare kare iyo HSDPA-based network yakatumidzwa se 3.5G kana Super-3G.
HSDPA yepamutemo yakagamuchirwa muna 2002. Inoshandisa teknolojia ye AM iyo inogadzirisa zvinyorwa maererano nehuwandu hwekutengesa mitambo.
HSUPA
High-Speed Uplink Packet Access inopa kukurumidza kuwedzerwa kwemafaira ekufambisa kwedhadhifoni pamaganho e 3G akafanana neHSDPA pakutsvaga. HSUPA inotsigira dhidha kusvika ku 5.7 Mbps. Nekugadzira, HSUPA haina kupa iyo yakaenzana nhamba ye data seHSPDA, nokuti vatapi vanogovera huwandu hweseri network network yea downlinks kuti ifanane nekushandiswa kwemaitiro evanoshandisa mafoni.
HSUPA yakatangwa muna 2004, mushure meHSDPA. Misangano iyo yakazopedzisira yakatsigira mbiri yakazozivikanwa seHSPA network.
HSPA naHSPA & # 43; 3G Networks
Shanduro yakasimbiswa yeHSPA inonzi HSPA + kana Evolved HSPA yakagadzirwa uye yakashandiswa nevatakuri vakawanda kuti vatsigire zviri nani kukura kukuru kwemasipiramu ehurumende yakawanda. HSPA + ndiyo inonyanya kukurumidza 3G protocol, inotsigira dhidha yepamusoro ye 42, 84 uye dzimwe nguva 168 Mbps zvekutsvaga uye kusvika 22 Mbps zvekutevera.
Apo iyo teknolojia yakatanga kuiswa, vashandisi veimwe mitambo yeGG vakaudza nyaya nehutano hwavo hwemagetsi kazhinji kushandura pakati peHSPA nemamwe ma 3G modes. HSPA neHSPA + kutendeseka kwekambani hakusi dambudziko zvakare. Kunze kwezvimwe zviitiko zvekugadzira magetsi, vashandisi ve 3G mitambo havadi kunyatsogadzirisa mafaira avo kuti vashandise HSPA kana HSPA + kana vatsigiri vavo vachikutsigira zvakanaka. Sezvimwe nemamwe mapurogiramu emagetsi, iyo chaiyo yemari inogona kuwanikwa nomunhu pane imwe foni yavo neHSPA kana HSPA + yakaderera kupfuura iyo inonzi maximums inotsanangurwa mumashamba ekutengeserana. Nzira dzeHSPA dzekudzivirira mahara mumitambo yehupenyu ndeye 10 Mbps kana yezasi neHSPA + uye yakaderera se 1 Mbps yeHSPA.
HSPA & # 43; Versus LTE
Izvo zvakakwirira dhamba yemari yeHSPA + yakakonzera vamwe mumhizha kuti vaione semichina ye 4G. Kunyange zvazvo HSPA + ichipa mamwe maitiro akafanana kubva kumunhu anoona, nyanzvi dzinobvumirana kuti teknolojia yakakura yeLTE yakajeka zvakajeka se 4G apo HSPA + haina. Chinokosha chinosiyanisa pamakwikwi akawanda ndeyekunonoka kwepachet latency iyo LTE inosangana neHSPA +.
