Ib qho txiaj ntsig tseem ceeb ntawm PoC yog tias nws tsis tsuas yog muab cov kev pabcuam PTT ceev nkaus xwb tab sis kuj muaj ib qho - rau -ntau pab pawg hu ua tus yam ntxwv ntawm PMR systems- ib qho tshwj xeeb feem ntau tsis tuaj ntawm cov qauv xov tooj ntawm tes. Tsis zoo li PMR tes hauj lwm, uas yog txwv tsis pub muaj peev xwm channel, PoC platforms txhawb kev tsim cov xov tooj tsis txwv ntawm cov xov tooj virtual thiab hu rau pab pawg, suav nrog cov pab pawg hu xov tooj. Tsis tas li ntawd, lub platform txhawb nqa cov kev pabcuam xa tawm-xws li qhov tiag- sijhawm GPS qhov chaw, taug qab, thiab saib xyuas- nrog rau lwm yam kev ua haujlwm ntawm PMR, xws li kev nkag mus rau hauv pab pawg hu lig thiab cov chaw taws teeb zoo nkauj lossis tua cov khoom siv.
Lub platform tseem muab lwm yam kev pabcuam PMR, xws li kev saib xyuas tus neeg ua haujlwm ib leeg thiab kev ceeb toom thaum muaj xwm txheej ceev, thaum muab kev hu xovtooj kaw, kaw lus, thiab muaj peev xwm ua si. Kev siv lub platform no, PoC cov cuab yeej tseem tuaj yeem suav nrog kev ua haujlwm ntawm PDA ib txwm muaj, xws li kev tswj hwm kev ua haujlwm, daim pib ua haujlwm, kev tshuaj xyuas cov khoom, thiab pov thawj - ntawm - cov kev pabcuam xa tuaj. Tsis tas li ntawd, qee qhov PoC platforms pab txhawb kev koom ua ke ntawm PoC cov kev pabcuam nrog PMR uas twb muaj lawm los ntawm cov rooj vag, yog li tsim kom muaj kev sib koom ua ke PMR / cellular network ib puag ncig. Qhov no ua rau muaj txiaj ntsig zoo rau thaj tsam ntawm PMR network, ua rau cov neeg ua haujlwm nyob sab nraud PMR network ntau yam - lossis cov tsis muaj PMR terminals - sib txuas lus seamlessly nrog cov neeg siv siv PTT -cov khoom siv ntawm tes.
