[technology development-24]: characteristics of existing IOT communication technology

Preface ：

The Internet of things （Internet of Things, abbreviation IoT） Means through various information sensor 、 RFID Technology 、 Global positioning system 、 Infrared sensors 、 Laser scanner and other devices and technologies , Real time acquisition any monitoring required 、 Connect 、 An interactive object or process , Gather the sound 、 light 、 heat 、 electric 、 Dynamics 、 chemical 、 biological 、 Location and other information needed , Through all kinds of possible network access , Realization and thing 、 The ubiquitous connection between things and people , Realize the control of items and processes Intelligent perception 、 Identify and manage .

The Internet of things is based on Internet 、 Traditional telecommunication network Information carrier , It allows all ordinary physical objects that can be independently addressed to form an interconnected network .

The Internet of things （ IoT ,Internet of things ） namely “ The Internet of things ”, It's an extension of the Internet , A huge network is formed by combining all kinds of information sensing devices with the network , Any time 、 Any place , people 、 machine 、 The interconnection of things .

The Internet of things is an important part of the new generation of information technology ,IT The industry is also called ： Pan interconnection , Signification Things are connected , All things are connected . thus ,“ The Internet of things is the Internet connected with things ”. This has two meanings ： First of all , Internet of things Core and foundation It's still the Internet , It's an extension and expansion of the Internet ; second , Its Client extensions and extensions here we are Anything and things Between , Information exchange and communication . therefore , The Internet of things is defined by RFID 、 Infrared sensors 、 Global positioning system 、 Laser scanner And other information sensing equipment , According to the agreement , Connect anything to the Internet , Information exchange and communication , In order to realize the intelligent identification of objects 、 location 、 track 、 A network of monitoring and management .

Key technologies include ： RFID Technology 、 Sensor network 、M2M System framework 、 Cloud computing
