Ama-PAN nama-WPAN ahlangene nama-Personal, Amadivayisi aseduze
Inethiwekhi yendawo yomuntu siqu (i-PAN) inethiwekhi yekhompyutha ehlelwe eduze komuntu ngamunye, futhi isethelwe ukusetshenziswa komuntu siqu kuphela. Ngokuvamile kufaka ikhompyutha, ifoni, iphrinta, ithebhulethi kanye / noma enye idivayisi yomuntu siqu njenge-PDA.
Isizathu se-PAN sihlukaniswa ngaphandle kwezinye izinhlobo zenethiwekhi ezifana ne- LAN , i- WLAN , i- WANs ne-MANs ngoba umqondo uwukudlulisa ulwazi phakathi kwamadivayisi aseduze kunokuthumela idatha efanayo ku-LAN noma i-WAN ngaphambi kokuba ifinyelele into esivele ingaphakathi finyelela.
Ungasebenzisa lamanethiwekhi ukuze uthumele amafayela afaka i-imeyli, ukuqoqwa kwekhalenda, izithombe, nomculo. Uma ukudluliselwa kwenziwa ngenethiwekhi engenazintambo, kuthiwa yi-WPAN, okuyinto inethiwekhi yendawo yangasese engenantambo .
Ubuchwepheshe Bokusetshenziswa Ukwakha I-PAN
Amanethiwekhi womuntu siqu angaba nge-wireless noma akhiwe ngamakhodi. I-USB ne- FireWire bavame ukuhlanganisa i-PAN ene-wired, kuyilapho i-WPAN isebenzisa i- Bluetooth (futhi ibizwa ngokuthi i-piconets) noma uxhumano lwe- infrared ngezinye izikhathi.
Nasi isibonelo: Ikhibhodi ye-Bluetooth ixhumeka kuthebhulethi ukulawula isikhombimsebenzisi esakwazi ukufinyelela i-bulb ekhanyayo yokukhanya.
Futhi iphrinta ehhovisi elincane noma ekhaya elixhuma kwideskithophu eseduze, i-laptop noma ifoni kubhekwa ukuthi ikhona ngaphakathi kwe-PAN. Kuyafana nakwamakhibhodi nakwamanye amadivaysi asebenzisa i-IrDA (i-Infrared Data Association).
Ngokweqiniso, i-PAN ingase ibe nezinsimbi ezincane, ezigqoka noma ezifakiwe ezingakwazi ukuxhumana nokuxhumana okuseduze namanye amadivayisi angenantambo. I-chip efakwe ngaphansi kwesikhumba somunwe, isibonelo, engagcina idatha yakho yezokwelapha, ingaxhuma nedivaysi ukuze idlulisele ulwazi lwakho kudokotela.
I-Big Big I-PAN?
Amanethiwekhi omuntu angenazintambo ngokuvamile ahlanganisa ububanzi bamamitha ambalwa kuya ku-10 amamitha (33 amamitha). Lawa amanethiwekhi angabhekwa njengohlobo olukhethekile (noma i-subset) yamanethiwekhi wendawo axhasa umuntu oyedwa esikhundleni seqembu.
Ubuhlobo bwedivayisi yobugqila bungenzeka endaweni ye-PAN lapho inombolo yamadivayisi ixhuma kudivayisi "eyinhloko" ebizwa ngokuthi yinkosi. Izigqila zidlulisela idatha ngokusebenzisa idivayisi enkulu. Nge-Bluetooth, ukusetha okunjalo kungaba mkhulu ngamamitha ayi-100 (330 amamitha).
Nakuba ama-PAN, ngokuchaza, ngokwabo, angakwazi ukufinyelela ku-intanethi ngaphansi kwezimo ezithile. Isibonelo, idivayisi ngaphakathi kwe-PAN ingaxhunyaniswa ku-LAN enokufinyelela kwi-intanethi, okuyi-WAN. Ngokwenza kanjalo, uhlobo lwenethiwekhi ngayinye luncane kunalolu olulandelayo, kodwa bonke bangakwazi ukuxhuma ngokuqondile.
Izinzuzo zenethiwekhi yomuntu siqu
Ama-PAN ayesetshenziselwa ukuzisebenzisa, ngakho-ke izinzuzo zingase ziqondwe kalula kunokuba uma ukhuluma ngamanethiwekhi amaningi, isibonelo, ezichaza i-intanethi. Ngenethiwekhi yendawo yomuntu siqu, amadivayisi akho siqu angakwazi ukuxhumana phakathi kokuxhumana okulula.
Ngokwesibonelo, igumbi lokuhlinza esibhedlela lingase libe ne-PAN yalo ukuze udokotela ohlinzayo akwazi ukuxhumana namanye amalungu eqembu ekamelweni. Akudingekile ukuba konke ukuxhumana kwabo kudliwe ngokusebenzisa inethiwekhi enkulu ukuze bathole abantu izinyawo ezimbalwa away. I-PAN ikhathalela lokhu ngokusebenzisa ukuxhumana okukhawulelwe okufushane njenge-Bluetooth.
Esinye isibonelo esibalulwe ngenhla sinenkhibhodi engenantambo noma ngisho negundane. Akudingeki ukuthi basebenzise amakhompiyutha kwezinye izakhiwo noma amadolobha, ngakho-ke bakhiwe ukuze baxhumane nedivayisi eseduzane, ngokuvamile evamile yokubona njengekhompyutha noma ithebhulethi.
Njengoba amadivaysi amaningi asekela ukuxhumana okukhawulelwe okuncane angavimbela ukuxhuma okungakagunyaziwe ngaphambili, i-WPAN ibhekwa njengenethiwekhi ephephile. Kodwa-ke, njengama-WLAN nezinye izinhlobo zenethiwekhi, inethiwekhi yendawo yomuntu siqu iyatholakala kalula kulabaduni abaseduze.
