Definitions
- the present application relates to the field of Internet of Things communication technologies, and in particular, to a data transmission method and apparatus.
- Frequency hopping communication is a branch of spread spectrum communication, and its advantage is strong anti-interference performance.
- the frequency hopping communication is a communication method in which the communication transmitting and receiving parties change the frequency synchronously, and the carrier frequency at the time of communication is always hopping.
- both transceivers must use the same hopping sequence.

- An enhanced machine type communication on unlicensed spectrum is a machine type communication technology that operates on an unlicensed spectrum.

The main working frequency is 2.4 GHz, which can also be extended to other unlicensed spectrum.

When some channels are used for frequency hopping multiple times, there will be laws that do not comply with the laws of various countries. In the case of rules, for example, the average occupancy time of each channel must not exceed 400 ms. That is to say, when some channel hopping is used multiple times, the rule that the average occupation time exceeds 400 ms occurs.
