FAQs
Ku dhowaad 14 Watts isticmaalka.
1W ayaa ku filan masaafo dhan 1km. Laakiin waxaanu kuu samayn doonaa 2W si aad u hubiso waxqabadka soo dhawaynta ugu fiican.
Waxay sidoo kale ku xiran tahay deegaankaaga deegaanka, ha ahaato LOS ama NLOS, fadlan hubi fiidyowgayada tijaabada ah, waxaa jira dabaqyo iyo dhismayaal badan.
Si aad u bedesho amplifiers awood kala duwan oo ku saabsan 500 MW, 1 Watt, 2 Watt, ama 10 watts. Ma aha oo kaliya hagaajinta goobta software-ka, Waxaad sidoo kale u baahan tahay inaad bedesho qalabka cod-weyneeye ee ku dhex jira gudbiyaha. Ma shaqayn karto oo isma beddeli karto isticmaaleha caadiga ah, iyo qiimaha iyo gudbiyaha birta sanduuqa size kala duwan yihiin.
Dejinta inta jeer ee caadiga ah waa 503 Mhz, 509 Mhz, 521 Mhz, iyo 521 Mhz in la doorto, hal badhan oo golaha wasiirada ah ayaa isbedeli kara. Haddii aad runtii u baahan tahay 1.3Ghz band oo kaliya, waa inaad doorataa nooc kale (1.2G ama 1.4G). Fadlan noo sheeg faahfaahinta dalabkaaga.
