Modern hotel organizations invest significant funds to increase quality of service. It is necessary to provide as much comfort as possible to both hotel guests and employees, which includes access to various multimedia services (Internet, VoD, IPTV service, etc.). Unified communications in hotel environment offer a quality solution to the problem of communication across hotel and contribute to the improvement of hotel services, as well as creating a good image. Unified Communications is a collection of applications and devices of the latest generation that allow users to dimension, control and manage calls, messages, data, and software tools from any location, using any device or software interface. Thanks to the diversity in the domain of information exchange, Unified Communications are applicable in almost all types of business environments.

The realized technical solution contains the Unify system of the OpenScape Business series as one of the most modern forms of TDM/IP hybrid solutions. The system offers a simple installation, maintenance and upgrade with minimal energy consumption compared to other systems. The problem of transferring multimedia real time signals through the IP network is solved by QoS mechanisms. The project envisages Firewall protection of the internal network on the Juniper Router page, which has all the necessary facilities to connect the hotel to the Internet. The technical solution also envisages the installation of SIP GSM gateway type 2N at a central location, with the possibility of up to 4 SIM cards, for calls to employees on mobile networks, which is considered an optimal solution for the needs of hotels with up to 50 employees.

Hotel environment is specific for several reasons. The network structure is, in most cases, subdivided into sub-networks for guests and employees. The functionality of the devices differs, and in each service it is enough to provide only a certain set of functions in order to provide guests with a fast and efficient service. The subnet for the guests is made up of the terminal devices brought by the guests and the terminal equipment owned by hotel. The terminal devices communicate over the Wi-Fi access point in the 2.4 or 5GHz band according to the IEEE 802.11b/g/n and 802.11ac standard with a dual-mode operation. IPTV platform provides high-quality IPTV service, but also delivers various additional information that the hotel wants to offer to its guests. The displays enable integration with smartphones and with the rest of the Hotel Systems. The technical solution also includes the installation of Headend having required capacity for receiving a television signal, as well as the installation of wireless telephony servers via DECT technology.

Unified communications system in hotel environment has a low maintenance cost, and provides customization to individual customer needs, portable services on every device, and the inclusion of new services that generates additional revenue. The implemented Unified Communications System optimizes and accelerates the process of information exchange within the hotel organization.
