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:
