According to the architectural characteristics of international hotels, our company believes that the intelligent construction of international hotels should be considered in three aspects besides various facilities suitable for five-star high-end hotels. First of all, in commercial hotels, we should focus on multilingual translation, multimedia display and remote transmission of large conferences. Secondly, considering the geographical location of international hotels, the requirements for electromechanical equipment for environmental adjustment are higher. From the point of view of intelligence, the building automation system is required to have higher adjustment ability; In addition, a five-star hotel is not only a requirement of facilities, but also a five-star service, so our company has configured (optional) a series of software and hardware facilities for international hotels to assist hotel management.

Good hotel architectural design creates a beautiful and elegant hotel environment and provides a reasonable and comfortable hotel service space for hotel services, while a well-equipped electromechanical system provides an economical, efficient, safe and comfortable service platform for hotel services, making all service functions of the hotel possible. It can be seen that the rational configuration of the electromechanical system of hotel buildings is particularly important in hotel construction. The electromechanical system of hotel building is a systematic project, involving many subsystems in many fields, such as architecture, communication, computer and network, automatic control and management, fire protection, security and so on. At the same time, there are many intersections and connections between subsystems. A good hotel electromechanical system configuration should organically unify these related subsystems into a whole, give full play to the functions of each subsystem, and provide an intelligent building electromechanical system integration with perfect functions, advanced equipment, convenient operation, safety and reliability, and economic investment.

Wireless network system
Business guests usually like to work with laptops in hotel lobbies, cafes or teahouses, or have short conversations in these places. At this time, guests need to deal with emails or download company information online.
The answers are often: "You have to change to a location near a certain data point", "You can go to the business center", or "You have to use the telephone line in your room to surf the Internet" and so on. The wireless intelligent hotel system can avoid this embarrassment. The wireless broadband service is mainly provided by arranging VLAN in the hotel, which can realize the overall access of the hotel in the shortest time without affecting the normal business of the hotel, especially the layout of the hotel decoration. Because meeting rooms and halls cannot be wired under special circumstances, these places often become dead ends covered by wired networks. And even if you want to wire, it is difficult to realize the specific scheme design and network laying because of the mobility of participants, uncertain location and large number of users. Laying a line occasionally will also make our network administrators very tired, because the scale of each meeting and the number of participants vary greatly. Moreover, because the wired network is used to lay the network, each user must use twisted pair to connect to the information socket of the network, so that the indoor network wires will be criss-crossed, which may sometimes affect the progress of the meeting for various reasons and bring inconvenience to users. It also takes a lot of manpower, material resources and time to quit the network, which will increase the accounting cost of the hotel. It is effective to use wireless network.
These problems are avoided.

Indoor wireless intercom
The hotel is a building with reinforced concrete structure. Using hand-held walkie-talkie to communicate can not achieve ideal communication effect, which brings great inconvenience to safety, security and fire fighting. Therefore, it is necessary to square it.
So as to establish an internal wireless communication network. In order to establish the hotel's internal communication network, the local management committee should allocate frequencies according to the usage of each hotel.
Special frequency of wireless communication network in Kunshan Fubang Hotel. Communication coverage: inside the hotel and the periphery with a radius of no more than 3 kilometers. Communication mode: using the same frequency simplex system.
Call quality: communication service level 3. The wireless communication network structure is based on the requirements of the Radio Management Committee for the hotel intranet: there should be good communication effect inside the hotel (that is, the communication range inside the hotel should meet the requirements of safety fire control communication). The external communication range should be small, generally not more than 3 kilometers (referring to fixed stations), so that more use can be realized with limited frequencies. Design basis To design a wireless intercom, we must first understand the structure of the building. Only on this basis can the position and density of receiving and transmitting antennas be reasonably arranged to prevent blind spots or waste.
