Izici ezithuthukisiwe zobumfihlo zokuphepha
I-DMR isekela ukubethela kwedijithali yesimanje nezindlela zokuqinisekisa. Ivimbela abanye abasebenzisi ekulaleleni ocingweni lwakho. Lesi sici senza ukuxhumana kuvikeleke futhi kuyimfihlo.
05
I-Frequency Range kanye nomkhawulokudonsa
I-DMR walkie{0}}talkies isebenza ngaphakathi kwamabhendi efrikhwensi afanayo namarediyo e-analog. Njenge-analog, basebenzisa i-Very High Frequency (VHF) ne-Ultra High Frequency (UHF). Amafrikhwensi e-VHF asukela ku-136 kuye ku-174 MHz, kuyilapho i-UHF iwela phakathi kuka-400 kuya ku-470 MHz.
Amasu Wokushintshashintsha
I-DMR digital walkie{0}}izingxoxo zisebenzisa indlela yokushintshashintsha ebizwa ngokuthi i-4-level Frequency Shift Keying (4FSK) ukuthumela imilayezo yezwi neyedatha. I-4FSK ibandakanya ukulungisa imvamisa yenkampani yenethiwekhi kwelinye lamazinga amane ahlukene wefrikhwensi.
Ukulungisa Iphutha Nokucubungula Isiginali Yedijithali
I-DMR walkie{0}}talkies inekhwalithi yomsindo ehamba phambili. Ngokungafani nemisakazo ye-analogi, i-DMR isebenzisa Ukulungiswa Kwephutha Lokudluliswa (i-FEC) nezindlela zokucubungula isignali yedijithali ukuthuthukisa ikhwalithi yomsindo.
I-Time Division Multiple Access (TDMA)
Imisakazo ye-DMR isebenzisa i-Time Division Multiple Access (TDMA). Okwenziwa yi-TDMA ukuhlukanisa isiteshi{1}}ezikhaleni ezimbili. Imbobo ngayinye ivamise ukuhlala ama-millisecond angu-30. Isikhathi sivumela amaqembu amabili ahlukene abasebenzisi ukuthi akhulume ngesikhathi esisodwa esiteshini esisodwa. I-TDMA isho ukuthi abantu abaningi bangakhuluma ngesikhathi esisodwa. Yehlisa ukusetshenziswa kwamandla futhi ingakhuphula impilo yebhethri yemisakazo ye-DMR.
Ukukhetha i-Dmr Walkie Elungile-i-Talkie
Ububanzi nokuphuma kwamandla
Imisakazo enomphumela ophezulu ikhava amabanga amade. Ngakho-ke, uma udinga ukuxhumana namabanga amade, hamba nemisakazo enelayisensi. Banamandla aphumayo aphezulu. Kodwa uzodinga ilayisense ukuze usebenzise eyodwa.
Ukuqina kanye Nokwakha Ikhwalithi
Ingabe uhlose ukusebenzisa irediyo yakho ezindaweni ezimbi njengezindawo zokwakha, izintaba, noma emahlathini? Bese, uzodinga i-walkie eqinile-enesakhiwo esimangelengele kanye nesilinganiso se-IP.
Impilo Yebhethri
Irediyo yezindlela ezimbili{0}ezinhle kufanele ihlale okungenani amahora angu-7-10. Kodwa, ububanzi bebhethri obungcono kakhulu buzoncika ekutheni ufuna ukuwusebenzisa kuphi umsakazo nokuthi isikhathi esingakanani. Uma kwenzeka ukhohlwa, khumbula ukuhlola izinketho zokushaja ezitholakalayo kuwe, njengamashaja emoto noma iphakethe lebhethri elengeziwe.
Izici Ezengeziwe Nezesekeli
Ungalokothi ulungele imodeli yokuqala oyibonayo, noma ngabe ibukeka iyinhle. Phinda{1}hlola izici kanye nentengo namanye amamodeli. Ezinye izici okufanele uziqaphele zihlanganisa ukubethela, ukuthumela imiyalezo, ukulandelela i-GPS, nomsebenzi we-Bluetooth.
Isigaba I-DMR: I-Tier I ifaka ilayisensi-yerediyo-yamahhala-yamahhala e-European Union nase-UK eneziteshi eziyi-16 phakathi kwamabhendi efrikhwensi angu-446 MHz no-446.2 MHz. I-Walkie-i-talkies engaphansi kwe-Tier I ingamarediyo aphansi-anamandla amakhulu okukhipha angu-500mW. Lezi zingxoxo{10}}zingasetshenziswa amabhizinisi amancane noma ukwenza imisebenzi yokuzijabulisa.
Isigaba II se-DMR: Kubhekiselwa kumarediyo anelayisensi,{0}aphezulu. Ngokuvamile basebenzisa amafrikhwensi aphakathi kuka-136 – 174 MHz ibhendi ye-VHF kanye nebhendi engu-403 – 527 MHz ye-UHF. Imisakazo ye-Tier II inezici ezithuthukisiwe ezifana noxhumo lwe-IP, umlayezo wombhalo, nokulandelela indawo ye-GPS. Le misakazo yenzelwe ikakhulukazi izilungiselelo nezimboni, futhi uzodinga ilayisense yokusebenzisa le misakazo.
Isigaba III se-DMR: I-Tier III ingeyamasistimu erediyo aqinile kuphela, okusho ukuthi imisakazo inikeze amaza ngokuzenzakalelayo esikhundleni sokuba namafrikhwensi angashintshi.
