Abstract

Većina današnjih terminalnih uređaja (prijenosnih računala, mobilnih telefona i sličnih uređaja) za pretraživanje i usluge koje zahtijeva korisnik koristi bežične LAN mreže. Bežične LAN mreže su de facto postale standard za povezivanje istih. Privlače sve veći broj korisnika zbog jednostavne implementacije, istovremeno osiguravajući nominalnu brzinu prijenosa. Veće nominalne brzine prijenosa olakšavaju pristup informacijama i reduciranje samih troškova mreže. Bežične mreže imaju puno prednosti, no najveći nedostatak koji stvara mnoge probleme je sigurnost. Nositelj informacije u bežičnim mrežama su radiofrekvencijski valovi, a medij kojim se prenose je zrak. Informacija koja se prenosi ne ostaje unutar objekta na području koje pokriva bežična mreža te je češće meta napada. Kako bi se detektirale i spriječile takve vrste napada, razvijeni su i koriste se razni sigurnosni oblici. Ovaj rad opisuje opće karakteristike bežične mreže kroz primjer CISCO bežične LAN mreže. Opisane su vrste arhitektura koje se mogu primijeniti u izradi bežične mreže, sigurnosni protokoli, kao i osnovna načela prijenosa signala i oprema potrebna za uspostavljanje mreže takvog tipa.

Abstract (english)

Most of today's terminal devices (laptops, mobile phones and similar devices) use wireless LAN networks for searching and services required by the user. Wireless LAN networks have become de facto the standard for connecting that type of device. They are attracting an increasing number of users due to their simple implementation, while providing a nominal transmission speed. Higher nominal transmission speeds facilitate access to information and reduce network costs. Wireless networks have many advantages, but the biggest disadvantage that creates many problems is security. The carrier of information in wireless networks are radio frequency waves and the medium through which they are transmitted is air. The information that is transmitted does not stay inside the object in the area covered by the wireless network and it is more often the target of attacks. In order to detect and prevent such types of attacks, various forms of security have been developed and are used. This paper describes the general characteristics of a wireless network through the example of a CISCO wireless LAN network. The types of architectures that can be applied in the creation of a wireless network, security protocols, as well as the basic principles of signal transmission and the equipment required to establish a network of this type are described.
