La-talinta Joogtada ah ee Wadnaha-Wadada 698-2700mhz n
Telsta balalka kooxda The The The The Thelco oo lammaaneyaasha kooxda 'Telsto' Waxay caadi ahaan ka kooban yihiin xariiq isku-darka ah isku-darka kolkay si kole ah u ah khadka ugu weyn. Hal dhamaadka qadka sadaqada ayaa si joogto ah loogu rakibay joojinta isdaba-joogga ah. Tilmaanta (farqiga u dhexeeya isugeynta hal jihayn ah oo loo barbardhigo kuwa kale) waa qiyaastii 20 DB oo loogu talagalay isku-darka, jihada jihada, kuwa isqaba ee loo adeegsado, jihada jihada ayaa la istcimaalaa marka loo eego in qayb ka mid ah seenyaalaha loo baahan yahay in la kala tago ama laba calaamadaha loo baahan yahay in la isku daro. Telesto waxay bixisaa koox ciriiri ah iyo koox aan toos ahayn oo jihooyin ah oo loogu tala galay is-weydaarsiga jihada leh ee isku-darka u dhexeeya 3 dB illaa 50 dB ama ka badan.

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).
Isku ururinta lowska dhabarka (fig3).

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.
