In accordance with the transmission distance to divide the wireless technology, our common Internet of things technology can be divided into long-distance communication and close communication networking technology.
Internet business needs huge, with a very obvious vertical industry characteristics is one of the current market concept of the popular.
Internet of things based on business scenarios can be broken down into three cases.
* Fixed or slow wireless data access (local networking)
* Mobile wireless data access (mobile Internet)
* Pan-wireless data access (low-power wide-area networking)
If the transmission distance in accordance with the distance to divide wireless technology, our common Internet of things technology can be divided into long-distance communication and close communication networking technology, generally classified as follows:<br />

NFC (RFID)
it is learned that the Ministry of Industry will be issued based on 13.56MHz near-field communication technology standards. Other areas of NFC and RFID bands refer to the following table:
* 125 kHz to 134 kHz
* 6.7 MHz
* 13.56 MHz (NFC)
* 27 MHz
* 433 MHz
* 865 MHz to 868 MHz (Europe)
* 902 MHz to 928 MHz (North America)
* 5.8 GHz
* 2.45 GHz
* 24.125 GHz
Z-Wave
* operating frequency in China is 868.40 MHz, complying with ETSI / EN 300 220 standard.
ZigBee / Thread / 6LoWPAN (IEEE 802.15.4)/ ISA100.11a and other specifications
* Based on IEEE 802.15.4 to be extended, the general IEEE 802.15.4 device used by the frequency of 868/915 / 2400MHz. Specific frequency reference is as follows:
* 169.4 to 169.475 MHz
* 250 to 750 MHz
* 779 to 787 MHz
* 863 to 879 MHz
* 896 to 960 MHz
* 1427 to 1518 MHz
* 2360 to 2483.5 MHz
* 3244 to 4742 MHz
* 5944 to 10234 MHz
* ZigBee 3.0, Thread, 6LoWPAN
* 2360 to 2483.5 MHz
