Pripravujeme vystavbu novej, fyzicky kompletne oddelenej trasy, ktora ma posilnit a zalohovat nasu sucasnu trasu. Trasa sa sklada z troch skokov, pricom najdlhsi ma 17km. Zamyslame nasadit silnejsie anteny ako tie, ktore su bezne dostupne. Min. zisk by mal byt 30dB. Zvazujem 30dB anteny, ktore kedysi dodaval Eastnet k Proxim Tsunami (robi to akasi ceska firma), no tie stoja 5700-5900/kus. Obzeram sa po nejakej lacnejsej alternative, ktora by dosahovala tiez aspon 30dB. Silnejsie anteny zamyslam nasadit aj na stavajucu trasu, kde je najdlhsi skok takmer 13km. Takze cely spas by ma vysiel na 24tis, cize sa snazim aspon cosi usetrit.

Chlapi, nerobte mi tu kazne o vysielacom vykone. 17km nie je zdaleka najdlhsia trasa, aka sa tu prejdnavala. Ked dam silne anteny, mozem tu vzdialenost preklenut s nizsim EIRP. Chapito?

ak chces kvalitne anteny tak PW-32 plne paraboly s radomom, ale 1 ks ta vyjde na cca 10 000 Sk.
Ak chces zisk a nizku cenu tak porozmyslaj o NN ozarovaci z i4 + 120 cm klasicku offsetovu parabolu, zisk bude okolo 34 dbi a cena do 3000 Sk za kus.

dalsie mozne riesenie je vymena radia (neviem co tam mas) za 400 mW SR5 karty s cipom od atherosu. tam by som vsak volil menej ziskove anteny, kedze s tymi kartami nieje problem preklenut vzdialenost 60km.

to alwarez> ale lepsie je pouzit silnejsie anteny, kedze maju uzsi vyzarovaci uhol, ako pouzit slabsiu a vyssi vykon na karte.

optimalna kombinacia na do20km trasy je SR5 (alebo CM11) + 24 PRO anteny.

anteny skladom mame, SR5 alebo CM11 sa daju doviezt (delivery time neviem).

40 km, 8 sieti, max 24 mbit/s, bolo by viac ale boli male anteny Smile

doplnim: ping do 2 ms, stratovost pri 1024 kb pakete pod 0.05%, vyzarovany vykon cca 200W, cena spoja do 20 000Skk.

Nie ze by sa taky spoj nedal spravit (400mW + 30dBi antena da EIRP cez 200W), ale prevadzkovat nieco take a este sa tym chvalit, je uz poriadne silne cafe.

Ten ozarovac z i4 mam na jednej trase cca 5km. Na obidvoch stranach su ofsetky 120cm a mikrotik s cm10 katami. Uroven signalu pri defaultnom vykone kariet je -42dbi.

ofsetka 120 + ten ozarovac je asi 35db a vyzarovaci uhol 3.4stupna.
