Jo\u0161 jedan va\u017ean dio planiranja be\u017ei\u010dne mre\u017ee je pokrivenost. Pravilno postavljanje Access Pointa je od klju\u010dnog zna\u010daja za maksimiziranje podru\u010dja be\u017ei\u010dne mre\u017ee koju \u0107e pokrivati. \u010cesto, to je samo stvar uklju\u010divanja Access Pointa gdje god je to prikladno. Me\u0111utim, postoje iznimke. Naprimjer, ako imate veliku ku\u0107u, mo\u017eda ne\u0107ete mo\u0107i pokriti cijelu ku\u0107u s jednim Access Pointom. Ukoliko vam nije potrebna pokrivenost u cijelom domu, onda je potrebno prona\u0107i najbolje mjesto za Access Point koji \u0107e pru\u017eati pokrivenost u sobama u kojima je potrebno. U suprotnom, morat \u0107ete instalirati vi\u0161e od jednog Access Pointa, koji zahtijeva neke dodatne konfiguracije, kao \u0161to su dodjeljivanje razli\u010dite IP adrese za be\u017ei\u010dne ure\u0111aje koji se povezuju na svaki Access Point, kako bi se osiguralo da dva ure\u0111aja ne dobiju istu IP adresu.<\/div>
Tako\u0111er, odre\u0111eni gra\u0111evinski materijali mogu ometati va\u0161 be\u017ei\u010dni signal, smanjuju ja\u010dinu signala i ukupnu pokrivenost. Naprimjer, debljina betonskih zidova u podrumu ili stambenoj zgradi mo\u017ee smanjiti pokrivenost.<\/div>
Iako mo\u017eete koristiti profesionalni alat koji \u0107e vam pomo\u0107i odrediti optimalan prostor za va\u0161 Access Point, obi\u010dno se koristi najlak\u0161i (i najjeftiniji) na\u010din, a to je eksperimentirati s nekoliko razli\u010ditih mjesta u va\u0161em domu.<\/div>
Op\u0161ta uputstva za postavljanje Access Pointa na optimalne lokacije navedena su u nastavku:<\/div>
U blizini centra na podru\u010dju na kojem nalazi ve\u0107ina ra\u010dunara i opreme, na povi\u0161enom polo\u017eaju, naprimjer, na visokoj polici.<\/div>
Daleko od te\u0161kih metala ili te\u0161kih betonskih povr\u0161ina.<\/div>
Daleko od mogu\u0107ih izvora smetnji, kao \u0161to su kuhinjski aparati i be\u017ei\u010dni telefoni.<\/div>

Kako pro\u0161iriti wifi signal bez kupovine aktivne mre\u017ene opreme (Ruter, AP)?<\/strong><\/div>
Prvo treba analizirati sam objekat, recimo, u pitanju je ku\u0107a od tri sprata. Koliko zidova ima izme\u0111u sporne pozicije i wifi rutera. Najgori su betonski zidovi po dijagonali. \u0160ta raditi u ovakvim slu\u010dajevima?<\/div>
Probajte da promjenite poziciju wifi rutera, prebacite ga na srednji sprat ili ukoliko imate veliki stan od 100m2, postavite ga na sredinu stana, kako bi ravnomjerno pokrio cijelu ku\u0107u, odnosno kako bi i najslabiji klijenti mogli da dobace do njega.<\/div>

Primarni parametar koji utje\u0107e na komunikacijsku udaljenost be\u017ei\u010dnog modula je snaga prijenosa. Uz pretpostavku da snaga oda\u0161iljanja zadovoljava zahtjeve, razmatraju se odabir antene i usmjerenost antene.<\/p>
