Nangona ukusabalala ngokubanzi kwezonxibelelwano eziphathekayo , i-landlines lineyilahlekelwa ukuthanda kwabo. Kungekudala, emakhaya nakwiiofisi, endaweni yezixhobo eziqhelekileyo, ii-radiotelephone zifakwe ngokubanzi. Ungayisebenzisi nje kuphela kummandla wefowuni, kodwa nayo yonke indawo. Kwabonakala kunye ne-radiotelephone ebizwa ngexesha elide.
Iyiphi i-radiotelephone ende?
Kuyaziwa ukuba ii-radiotelephones zithumela iimpawu zezwi ngokusebenzisa uqhagamshelwano lomsakazo. Xoxa ngabo nantoni na kwiofisi yakho okanye kwikhaya, mhlawumbi uhambahamba kwintsimi. Nangona kunjalo, i-radius yezenzo zaloo radiotelefoni ayidluli, njengommiselo, u-15-400 m. Ngako oko, akunakwenzeka ukuba ushiye indlu kwaye usebenzise unxibelelwano oluncinci olunxibelelwano, ngakumbi ukususela ekuhlambulukeni kwabo (30-50 MHz) akuvumeli oku.
Yingakho i-radiotelephone eneentlobo ezininzi zezenzo zenziwe. Njengomthetho, zisetyenziselwa kwiindawo ezinkulu zeefektri, ii-workshops, iifeksi, iziseko zorhwebo, amashishini ezolimo, izakhiwo zokwakha, njl njl. Ukusetyenziswa kwee-radiotelephone ezinokude kwinto enokwenzeka kwaye, ukuba kunyanzelekile, ukubonelela nge-dacha, igaraji okanye indlu. Oko kukuthi, xa kungekho mnqweno okanye unako ukuxhuma kwinethiwekhi yomnxeba wendawo.
Ukusebenza kwinqanaba le-frequency ukusuka kuma-250 ukuya ku-400 MHz, ezi fowuni zinika uxhulumaniso ngaphakathi kwimizila yeekhilomitha ezimashumi amabini ukuya kweebini kwimimandla yasezidolophini. Kwiindawo zasemaphandleni, esi sibonakaliso sifinyelela kuma-25-60 km, esekelwe kwimimiselo ethile.
Ungakhetha njani i-radiotelephone ende?
Ukukhethwa kwe-radiotelephone ene-radius enkulu yesenzo kunokuxhomekeka kwiiparitha eziliqela. Kwiofisi kungcono ukhethe umzekelo apho isiseko sidibanisa amaninzi amathubhu ngokunokwenzeka. Kuhle ukuba ifowuni isekela umsebenzi wesazisi onobulumko okanye kukho ifowuni kuyo. Ukunokwenzeka kwenkomfa kuya kunceda ukuxazulula ixesha lokusebenza ngokukhawuleza kunokwenzeka.
Namhlanje, xa uthengiswa ungayifumana imikhiqizo evela kubakhiqizi ababini abanokwethenjelwa kunye namashumi eminyaka. Iifoni ze-Senao EnGenius ezenziwe eTaiwan zinemizekelo emininzi yokusetyenziswa kwekhaya kunye neofisi. Ii-radiotelephone ezide ixesha i-Panasonic ikwahluke kumgangatho kunye nephakamileyo eliphezulu lokuthembeka. Bobabini abakhiqizi banikela ngemveliso yabo kwimiba ehlukeneyo yamanani.
