Two-Way Radio Matut mahkai Ladat ni hpe hpaji masa hku sawk sagawn nna jai lang ai lam

Two-way radio (walkie{1}}talkie communication ngu nna mung shamying ai) gaw, mung shawa shimlam, htawt sit lam, hpaga lam galaw ai lam ni, shinggan de pru hkawm ai lam ni hta grai lang ai, shara -to-point (sh) point-to-multipoint instant wireless matut mahkai hpaji masa rai nga ai. Shi a madung akyu gaw, cellular network npawt nhpang hpe n kam sham ai sha, aten dep-nsen hte matut mahkai lu ai lam rai nga ai. Shi gaw asan sha, n-gun ja ai shingjawng ai lam hpe ninghkap lu ai, manu n-htuk ai hku nna laklai nga ai.

Lahkawng-lam radio matut mahkai ladat ni gaw madung hku nna, daw mi-duplex (sh) hkum tsup-duplex ladat ni hpe madung tawn ai. Half-duplex mode hta, lang ai wa gaw "Push-to-Talk" ngu ai hpe dip nna, signal langai hpe shalai dat ai. Dai hpe shapraw dat ai shaloi, signal gaw receive mode de galai mat nna, langai lang hta channel langai kaw sha, party langai sha shapoi ya lu ai hpe kam mai ai. Full-duplex mode gaw, lahkawng maga na nsen shiga ni hpe kalang ta shagun ya lu ai, hkap la lu ai, mobile phone shaga ai hte bung ai, raitim, laksan hku nna gaw, grau dam lada ai spectrum resource ra ai rai nna, professional digital trunking system ni hta law law lang mu lu ai.

Hpaji masa hku yu yang, -lam lahkawng lang na radio ni gaw VHF (Grai tsaw ai nsen, 30-300 MHz) hte UHF (Grai tsaw ai nsen, 300-3000 MHz) nsen band ni hpe kam hpa nga ai. VHF gaw n-gun ja ai shang wa ai lam hpe jaw ya nna, hpaw da ai shara ni hta htuk manu ai, UHF gaw grau kaja ai diffraction resistance hpe jaw ya nna, mare kaba ni hta n-gun ja ai shara ni hta htuk manu ai. Digital matut mahkai hpaji ni (DMR hte P25 zawn re ai ni) gaw spectrum hpe grau kaja hkra galaw ya ai, encrypted transmission hte data services ni hpe madi shadaw ya ai, matut mahkai lam a shimlam hte bungli galaw ai lam hpe grau kaja hkra galaw ya ai.

Tatut jai lang ai lam hta, lahkawng-way radio ni hpe jai lang na matu, channel masing jahkrat ai lam, n-gun hpe hkang ai lam, antenna lata ai lam ni hpe myit yu ra ai. Ga shadawn, high-power jak ni gaw tsan ai shara de matut mahkai na matu htuk manu ai, n-gun kaji ai -power jak ni gaw tsan ai shara hte n-gun kaba ai -density scenarios ni a matu grau htuk manu ai. Dai hta n-ga, repeater ni gaw signal ni hpe hkap la nna, matut mahkai ai lam hku nna, coverage hpe jat ya lu ai majaw, cross-regional matut mahkai lam hpe galaw lu ai.

Tsun ga nga yang, two-way radio ni gaw kam hpa mai ai hte galai shai mai ai majaw, lawan ladan karum shingtau ai lam hte hpung jawm galaw ai lam hta galai shai n lu ai hku naw rai nga ai. Digital hpaji masa ni hpe hpawng de ai hte, shanhte a matut mahkai lam a hkamja lam hte bungli galaw ai lam ni hpe grau nna gram lajang nna, dai ni na aten na matut mahkai lam amyu myu a ra kadawn ai lam ni hpe hkap la lu na re.
