Yintoni umahluko phakathi kwerediyo ye-poc kunye nee-walkie-talkies eziqhelekileyo?
I-walkie-talkie sisixhobo sonxibelelwano esingenazingcingo esisetyenziswa kakhulu kumashishini ahlukeneyo nakwiindawo. Xa sixoxa ngee-walkie-talkies, sihlala siva amagama athi "poc" kunye "nenethiwekhi yabucala." Ngoko ke, yintoni umahluko phakathi kwezi zimbini? Ukuphendula lo mbuzo, mandikuse kwingqiqo enzulu ukukunceda uqonde ngcono xa ukhetha ukuba loluphi uhlobo lwenethiwekhi.
1. Injongo:
Irediyo yePoc isebenzisa uthungelwano lonxibelelwano lukawonke-wonke, olufana nothungelwano lweefowuni eziphathwayo okanye i-Intanethi, njengeziseko zonxibelelwano zabo. Oku kuthetha ukuba zinokusetyenziswa kwihlabathi jikelele, kodwa zihlala zilinganiselwe ngokufumaneka kwenethiwekhi kunye ne-bandwidth. Irediyo ye-poc ifanelekile kuluhlu olubanzi lwezicelo ezinjengonxibelelwano lobuqu, uhlangulo olungxamisekileyo kunye nokusetyenziswa kwe-amateur.
Ii-intercom zenethiwekhi zabucala: Ii-intercom zenethiwekhi zabucala zisebenzisa injongo eyakhelweyo, uthungelwano lwabucala lonxibelelwano oludla ngokulawulwa ngoorhulumente, amashishini, okanye imibutho ngokwayo. Injongo yolu hlobo lothungelwano kukubonelela ngonxibelelwano olukhuselekileyo noluthembekileyo kwaye lusetyenziswa ngokuqhelekileyo kukhuseleko loluntu, emkhosini, kwimizi-mveliso nakwizicelo zorhwebo.
2. Ukhuseleko:
Irediyo ye-Poc: Irediyo ye-poc ihlala inosasazo olubanzi kwaye inokusetyenziswa kwihlabathi liphela. Oku kubenza babe lukhetho olulungileyo lokunxibelelana kwiindawo ngejografi.
Oonomathotholo bothungelwano lwabucala: Oonomathotholo bothungelwano lwabucala ngokuqhelekileyo banosasazo olulinganiselweyo, bahlala begubungela kuphela umbutho okanye indawo ethile. Oku kuqinisekisa ukhuseleko lonxibelelwano olukhulu kunye nolawulo olungcono.
3. Ukusebenza kunye nokuthembeka:
Irediyo ye-Poc: Ukusebenza kunye nokuthembeka koonomathotholo be-poc kuchatshazelwa luthungelwano lonxibelelwano loluntu. Ngexesha lomthwalo ophezulu okanye iimeko zongxamiseko, banokuba sengozini yokuxinana kunye nokuphazamiseka konxibelelwano.
Irediyo zeNethiwekhi yabucala: Irediyo zenethiwekhi yabucala ngokubanzi zinentsebenzo ephezulu kunye nokuthembeka kuba zakhiwe kuthungelwano oluyilwe ngokukodwa. Oku kubenza bakwazi ukubonelela ngeenkonzo zonxibelelwano ezingcono ngexesha likaxakeka.
4. Ukhuseleko:
Irediyo ye-poc: Unxibelelwano nge-poc lunokusongelwa yimingcipheko yokhuseleko lwenethiwekhi. Oku kuyenza ingafaneleki ukuphatha ulwazi olubuthathaka.
Inethiwekhi yabucala ye-walkie-talkies: I-walkie-talkies yenethiwekhi yabucala ihlala inokhuseleko oluphezulu kwaye isebenzisa i-encryption kunye namanye amanyathelo okhuseleko ukukhusela umxholo wonxibelelwano ekuphazamisekeni okunonya.
5. Ulawulo:
Irediyo ye-Poc:, kukho ulawulo oluncinci kunye netrafikhi yonxibelelwano ngokuqhelekileyo ayinakwenziwa ngokwezifiso. Oku kudala imingeni ekulawuleni unxibelelwano kunye nokugcina ukuziphatha kakuhle.
Ii-Intercoms zeNethiwekhi yabucala: Ii-Intercoms zeNethiwekhi zabucala zilawulwa ngokupheleleyo ngumbutho kwaye zinokucwangciswa ngokwesiko kwaye zilawulwe njengoko zifuneka. Oku kuyenza ifaneleke ngakumbi kwiimfuno ezithile zesicelo.
Ngokubanzi, irediyo ye-poc ifanelekile kwiimfuno zonxibelelwano ngokubanzi, ngelixa i-walkie-talkies yenethiwekhi yabucala ifanelekile ngakumbi kwizicelo ezikhethekileyo ezifuna iqondo eliphezulu lokhuseleko kunye nokuthembeka, njengokhuseleko loluntu, umkhosi, kunye noshishino. U-AiShou ngumvelisi oqeqeshiweyo we-walkie-talkies. Iimveliso zayo zigubungela i-poc, inethiwekhi yabucala, kunye ne-DMR yedijithali-analog ehlanganisiweyo ye-walkie-talkies.
