DMR vs. Analogi Walkie{1}}Talkies
Kukweza kwamawu
Mawayilesi a DMR ali ndi mawu abwinoko kuposa analogi. Kukonza zomvera pa digito kumachepetsa phokoso lakumbuyo ndikukonzanso ma siginecha kuchokera kumayendedwe owonongeka. Chifukwa chake, ogwiritsa ntchito amatha kulumikizana ngakhale m'mphepete mwa kufalitsa.
01
Mtundu wowongoleredwa
Mawayilesi a DMR amatha kulowa mnyumba ndi zopinga zina. Ndipo izi zimawonjezera kufalikira kwawo.
02
Kuthekera kwakukulu
DMR imagwiritsa ntchito matekinoloje a Time Division Multiple Access (TDMA) omwe amalola ogwiritsa ntchito ambiri kuti azilankhulana nthawi imodzi, pafupipafupi.
03
Moyo wabwino wa batri
TDMA imachepetsa kugwiritsa ntchito mphamvu mu mawailesi a DMR. Kuyimba kumagwiritsa ntchito nthawi imodzi yokha{1}}pawiri, motero kumagwiritsa ntchito mphamvu zochepa. Chifukwa chake, izi zidzawonjezera moyo wa batri.
04
Zazinsinsi zapamwamba komanso chitetezo
DMR imathandizira kubisa kwa digito ndi njira zotsimikizira. Zimalepheretsa ogwiritsa ntchito ena kumvetsera pafoni yanu. Izi zimapangitsa kulumikizana kukhala kotetezeka komanso kwachinsinsi.
05
Frequency Range ndi Bandwidth
DMR walkie-talkies imagwira ntchito m'ma frequency ofanana ndi mawailesi a analogi. Monga analogi, amagwiritsa ntchito Very High Frequency (VHF) ndi Ultra High Frequency (UHF). Ma frequency a VHF amachokera ku 136 mpaka 174 MHz, pomwe UHF imatsika pakati pa 400 mpaka 470 MHz.
Njira Zosinthira
DMR digital walkie-talkies amagwiritsa ntchito njira yosinthira mawu yotchedwa 4-level Frequency Shift Keying (4FSK) kutumiza mauthenga amawu ndi data. 4FSK imaphatikizapo kusintha ma frequency onyamula kukhala amodzi mwa magawo anayi osiyanasiyana.
Kukonza Zolakwa ndi Kusintha kwa Ma Signal
DMR walkie-talkies ili ndi imodzi mwamawu abwino kwambiri. Mosiyana ndi mawailesi a analogi, DMR imagwiritsa ntchito Forward Error Correction (FEC) ndi njira zosinthira ma siginolo a digito kuti ziwongolere mawu.
Time Division Multiple Access (TDMA)
Mawayilesi a DMR amagwiritsa ntchito Time Division Multiple Access (TDMA). Zomwe TDMA imachita ndikugawa tchanelo-pawiri. Malo aliwonse nthawi zambiri amakhala 30 milliseconds. Nthawiyi imalola magulu awiri osiyana a ogwiritsa ntchito kulankhula nthawi imodzi panjira imodzi. TDMA imatanthauza kuti anthu ambiri amatha kulankhula nthawi imodzi. Imachepetsa kugwiritsa ntchito mphamvu ndipo imatha kuwonjezera moyo wa batri wa mawailesi a DMR.
