Mau Oyambirira Kufunsira Kwazowonjezera & zochitika Mapangidwe Apadera / Chitsimikizo 2W GSM900MHz Air Coupling Frequency Shifting Repeater idapangidwa kuti ithe kuthana ndi zovuta zamafoni osafooka, omwe ndiotsika mtengo kwambiri kuposa kuwonjezera Base Station yatsopano (BTS). Malinga ndi njira yolandirira chizindikiro cha BTS ndi Donor Unit, mitundu iwiri ya FSR ikupezeka: 1.

Mpweya wa 2W GSM900MHz Kuphatikizana pafupipafupi Kusuntha Bwerezani lakonzedwa kuti athetse mavuto a mafoni ofooka, omwe ndiotsika mtengo kwambiri kuposa kuwonjezera Base Station yatsopano (BTS).
Malinga ndi njira yolandirira chizindikiro cha BTS ndi Donor Unit, mitundu iwiri ya FSR ikupezeka:
1. Cable-Access FSR: Kuti mulandire chizindikiro cha BTS kudzera pa coupler yolunjika yotsekedwa ku BTS (Yalangizidwa);
2. Wireless-Access FSR: Chizindikiro cha BTS cholandila kudzera pa Donor Antenna (chimagwira ngati palibe mzere wowonera pakati pa Donor Unit ndi Remote Unit pomwe Donor Unit imayikidwa pa nsanja ya BTS).
 

Ndipo mitundu yonse ya FSR itha kusanjidwa m'magulu awiri malinga ndi kupezeka kwa mayendedwe pafupipafupi:
1. In-band FSR: Ma frequency olumikizana ali mkati mwa gulu logwira ntchito la BTS;
2. Out-of-Band FSR: Ma frequency amalumikizana ali kunja kwa gulu logwira ntchito la BTS.

Kutsegulira

  Zofunika Kwambiri                              
1.Mkulu kudzipatula zonse duplex kamangidwe, zovuta kukhazikitsa.
2. Phokoso lochepa, kulandila kwambiri.
3. Ndi ALC ndi MLC ntchito kuonetsetsa khola linanena bungwe mphamvu.
4. Kugwiritsa ntchito mphamvu zochepa, kuteteza zachilengedwe komanso kupulumutsa mphamvu.
5.Kapangidwe kakang'ono kosavuta, kosavuta kukweza dongosolo.
6. Fyuluta yam'mimbamo ya Q Q ndi SAW pamwamba paphokoso lamayimbidwe osefera, kukanidwa kwambiri ndi gulu.
7.Landirani mzere wapamwamba kwambiri wapadziko lonse lapansi, kutsika kwapakatikati kwa LDMOS amplifier mphamvu.
8.Landirani zapamwamba za digito PLL, TCXO, ukadaulo wa OCXO, kukhazikika kwanthawi yayitali komanso kulondola kwambiri.
9. Ntchito yabwino kwambiri yowunikira ma network.
10. Ntchito yopanga madzi yopanda nyengo yonse yakunja ndi panja.

Kugwiritsa ntchito & zochitika

Mapulogalamu
    Kukulitsa kufotokozera kwamalo akudzaza malo akhungu pomwe chizindikiro ndi chofooka  
kapena sakupezeka.
   Kunja: Ndege, Madera Oyendera, Maphunziro a Gofu, Ngalande, Mafakitole, Madera Akumigodi, midzi
   M'nyumba: Hotelo, Malo Owonetsera, Malo Apansi, Kugula
Zogulitsa, Maofesi, Kuyika Ma Loti ndi zina zambiri.
Zimagwira ntchito ngati izi:
    Wobwereza atha kupeza malo oyikiramo omwe angalandire mbendera yoyera ya BTS pamlingo wokwanira popeza Rx Level patsamba lobwereza iyenera kukhala yoposa ‐70dBm;

    Ndipo akhoza kukwaniritsa zofunikira za kudzipatula kwa mlongoti kuti mupewe kudzikweza.
