System and method for realizing communication based on existing WiFi network

Abstract

The invention discloses a system for realizing communication based on an existing WiFi network. The system is composed of a WiFi intercom terminal, a WiFi wireless network and a WiFi intercom management platform, wherein the WiFi intercom terminal uses the wide area network WiFi access technology, and is connected to the WiFi intercom management platform through any global AP hotspot so as to realize the WiFi voice intercom function. As long as there is the WiFi network, WiFi intercom terminals can achieve local and cross-region wireless intercom, and the frequency point cost and call cost arenot needed to be paid, full duplex communication can be realized easily, and the voice is very clear. Further, a video data upload function can be realized by using a terminal with a screen. The system of the invention has simple system architecture, fast arrangement, powerful function and low cost, and can be widely used in star hotels, large-scale hospitals, medical examination centers, large malls and supermarkets, large warehouses, sports centers, airport ground services, catering enterprises, production enterprises, security duty, substation routing inspection and other scenes.

Description

technical field [0001] The invention relates to the field of wireless walkie-talkies, in particular to a system and method for realizing communication based on an existing WiFi network. Background technique [0002] With the rapid construction of global digital cities, the coverage of WiFi wireless hotspots is becoming more and more mature. In our daily life and work, we can access WiFi signals anytime and anywhere, and conduct data transmission, data sharing and data access worldwide through the Internet. For example: hotels, offices, corporate parks, industry WIFI private networks, etc. It has become a reality to use these WIFI signals to realize voice intercom technology on a global scale. Such WIFI intercom terminals can realize voice services of traditional analog / digital walkie-talkies on a global scale without building a professional signal coverage network. In addition to realizing wide-area voice intercom functions, it can support image and video transmission funct...

Problems solved by technology

[0003] Conventional analog / digital intercom systems have single functions and high networking costs, which are difficult to meet the needs of the security industry, hotel industry, property management, prisons, hospitals and other industries

At present, the existing WiFi intercom on the market needs to set up a special WiFi hotspot channel, instead of using the existing WiFi network hotspot to directly interconnect and intercommunicate the intercom terminals, and only supports the LAN with the same SSID
