The thesis describes the setting of wireless network, its operation and use in business purposes in the campsite Dolenjske Toplice. Several factors, necessary for the reliable operation and internet access safety are taken in consideration. Thesis describes the procedures that allow guest-friendly access to the network via access points distributed throughout the campsite. It also deals with logging into the guest network. Practical part of the thesis presents the configuration of devices, installation of infrastructure, monitoring and testing of the established network. It describes the settings of the Mikrotik router, firewall rules and an optimal distribution of internet services among users. Even though the network is not a professional commercial solution, most of the users confirmed its operation. The network also endured higher system loads and is therefore set for mass use. There are, however, a lot of opportunities for revision, upgrading and further development.
