Kala-guurka korantada ee Thelsto waxay ku jiraan 2, 3 iyo 4 siyaabood
Muujinta
Kala-guurka korantada ee Telsto waxay ku jiraan 2, 3 iyo 4, u isticmaal strafile iyo daloolka farsamada gacanta, wata-qaadeyaasha aluminium guryaha, oo leh muuqaal aad u fiican, qiimeynta awooda sare, qiimeynta korantada, pim yar iyo khasaare aad u hooseeya. Farsamooyinka naqshadeynta heer sare ah waxay u oggolaadaan faashad ka soo baxa 698 illaa 2700 MHZ guryaha dhererka habboon. Daloolka goynta ayaa inta badan ka shaqeeya dhisida daboolka wireless-ka iyo nidaamyada qaybinta dibedda. Sababtoo ah iyagu waa kuwa aan la arki karin, khasaare hooseeya iyo pim hooseeya.
Vintry Vesswr,
Qiimaynta awooda sare,
Pim hooseeya,
Daboolida soo noqnoqda ee kooxeedyada badan,
Naqshadeynta qiimaha jaban, qaabeynta qiimaha,
Isku halaynta sare iyo dayactirka lacag la'aan,
Xaaladaha Shahaadada IP ee badan
Rohs waafaqsan,
N, Din 4.3-10 Xiriirka,
Naqshadaynta caadada ah ee la heli karo,
Isticmaal
Kala-goynta awoodda ayaa kuu oggolaanaysa inaad u isticmaasho nidaamka isugeynta guud ee dhammaan codsiyada isgaarsiinta guur-guura ee tirada guud ee soo noqnoqda.
Marka seenyaalaha loo qaybiyo qaybinta guriga, dhismayaasha xafiiska ama hoolalka isboortiga, kala-goynta awoodda ayaa u kala qaybin kara seenyaalaha soo gala laba, saddex, afar ama ka badan saamiyo isku mid ah.
U kala qaybi hal calaamad oo ku gal kanaallo badan oo ah kuwa, oo hubiya in nidaamka uu la wadaago ilaha astaanta guud iyo nidaamka BTS.
La kulan baahiyo kala duwan oo nidaamyada shabakadaha oo leh naqshadda kooxda ee ballaaran.

Qiyaasta cabirrada ayaa ah sida lagu muujiyey jaantuska (FIG2), fiiro-wadaag waa in la bixiyaa inta uu sii socdo:
1. Dusha kore ee dusha sare ee ka hortagga gudaha waa in la sheegaa.
2. Ka saar cilado la'aanta sida cabirka naxaasta iyo burr dusha sare ee fiilada.
Isu ururinta qaybta shaabadaysan: Ku xoq qaybta shaabadaysan ee ku taal dariiqa kore ee fiilada sida ay muujisay jaantuska (fignimada).

1. Kahor intaadan xoqin, smear lakabka oo saliidaha saliidaha dufanka o-giraan.
2. Hayso dhabarka lowska iyo fiilada dhaqdhaqaaqa, ku dabool jirka dufanka ugu weyn ee maqaarka dhabarka. Hoos u dhig jirka dufanka ugu weyn ee jirka oo dhabarka ah ee ku dheji jirka dushooda adoo adeegsanaya kabaha daanyeerka. Isku-ururiddu waa dhammaatay.
