Lahkawng-Lam Radio Range hte Dai hpe hkra machyi shangun ai lam ni

Walkie-talkies ngu nna mung shamying ai, lahkawng lang na radio ni gaw, cellular network hpe n kam sham ai sha, kalang ta matut mahkai lu ai arung arai ni rai nga ai. Shanhte hpe mung shawa shimlam, hpaga lam, shinggan magam bungli ni hta grai lang ma ai. Shanhte a range hpe lam amyu myu a majaw hkra machyi shangun nna, dai lam ni hpe chye na ai gaw, shanhte hpe hkrak hkra lata nna jai lang lu na matu karum ya lu ai.

Two-way radio ni a theoretical range gaw, laksan hku nna, kilometer loi mi kaw nna kilometer shi daram du hkra rai nga ai, raitim, tatut hta gaw, grau kadun ai aten law law nga ai. Kaja dik ai masa ni hta, hpaw da ai, pat shingdang ai lam n nga ai ginra ni (sh) tsaw ai shara ni hta, n-gun kaba ai-shapoi ai jak ni hte kaja ai antenna ni hte hpawng de da ai hpaji ninghkring ni a jak ni gaw, deng shi daram tsan ai shara de du lu ai. Raitim, n-gun ja ai shara ni, bum ga ni, shing nrai nam maling ni zawn re ai yak hkak ai makau grup yin ni hta, signal hpe pat shingdang ai lam hte lam law law hpe pat shingdang ai lam ni gaw, akyu rawng ai shara hpe metre latsa daram (sh) dai hta n-ga, shayawm kau ya lu ai.

Transmitter power gaw n-gun hpe dawdan ai hta ahkyak ai lam langai rai nga ai. Madung hku tsun ga nga yang, power grau tsaw ai ngu ai gaw signal shapoi ai tsan ai shara grau tsan ai hpe tsun mayu ai. Mung shawa walkie-talkie ni gaw 0.5 kaw nna 2 watts du hkra n-gun lang ai rai nna, hpaji ninghkring ni a jak ni gaw 5 watts (sh) dai hta jan nna n-gun lang ai. Antenna amyu hte tsaw de mung ahkyak ai. High-gain directional antenna ni gaw galu kaba ai hku matut mahkai lu ai atsam hpe grai shatsaw ya lu ai, antenna hpe grau tsaw ai hku tawn da ai gaw signal coverage hpe grau jat shangun ai.

Two-way radio ni a range hpe hkra machyi shangun ai hta grup yin masa ni hpe n mai malap kau ai. Hka lum ai, marang, hka lim ai gaw radio wave nkau mi hpe hkap la lu nna, wan n-gun n-gun (ga shadawn, high-voltage wan n-gun line ni hte electronic jak ni kaw na) gaw signal hpe shayawm kau ya lu ai. Dai hta n-ga, frequency hpe lata ai lam mung ahkyak ai. VHF (grai tsaw ai frequency, 30-300MHz) gaw wavelength grau galu nna, n-gun n rawng ai raitim, diffraction grau n-gun ja ai majaw, hpaw da ai shara ni hta grau htuk manu ai. UHF (ultra-high frequency, 300-3000MHz) gaw n-gun kadun ai hte n-gun ja ai hku shang wa ai raitim, pat shingdang ai lam ni a majaw loi loi hte pat shingdang lu ai majaw mare kaba ni hta grau htuk manu ai.

Tsun ga nga yang, lahkawng-way radio a matut mahkai ai lam gaw, masat da ai manu n re; dai hpe device parameters, grup yin masa, frequency lata ai lam ni hpe kahkyin gumdin ai hku nna dawdan ai. User ni gaw shanhte a device configuration hpe shanhte ra kadawn ai lam hte maren gram lajang ra ai, dai hku nna kaja dik ai hku matut mahkai lu na matu re.
