一种近距离通信服务装置

Near-distance communication service apparatus

Abstract

本发明提供一种近距离通信服务装置,至少包括可采用广播方式发送数据且广播距离有限的发送端子装置和可以在不需要事先与发送端子装置建立通信链路就可直接接收发送端子装置采用广播方式发送的数据并可根据内容选择接收数据的接收端子装置两个部分,发送端子装置数量受通信带宽限制但接收端子装置数量不受通信带宽限制;本装置可以无线方式或有线方式提供音频、视频、图片、文本或指令等数据服务,数据可以无线电波、光波、导电线缆的电信号或导光线缆的光信号形式传输,接收端子装置可具有以可视、可听、可闻、可温感或可触感方式展示所接收数据的部件或其组合。本发明提供的近距离通信服务装置方便的实现了近距离通信服务,减少流量压力和成本。
The invention discloses a near-distance communication service apparatus. The apparatus at least comprises two portions, i.e., sending terminal devices which can send data by use of a broadcast mode and have limited broadcast distances, and receiving terminal devices which directly receive the data sent by the sending terminal devices by use of the broadcast mode without establishing communication links with the sending terminal devices in advance and can selectively receive the data according to content. The quantity of the sending terminal devices is restricted to communication bandwidth yet the quantity of the receiving terminal devices is not restricted to the communication bandwidth. According to the invention, data service such as audio, videos, pictures, texts or instructions and the like can be provided by in a wireless mode or a wired mode, the data can be transmitted in the form of radio waves, light waves, electric signals of conductive cables or optical signals of light guide cables, and the receiving terminal devices can be provided with parts or combinations for displaying the received data through a visual, audio, audible, temperature-sensing or touch mode. The near-distance communication service apparatus provided by the invention conveniently realizes near-distance communication service and decreases flow pressure and the cost.
