Protocols

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:

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)

  • 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
