Abstract: According to the present invention, disclosed is a method of adjusting a transmission cycle of a wireless terminal transceiving data with a monitoring server. According to the present invention, the transmission cycle adjustment method includes: a step wherein a wireless terminal creates transmission standby data; a step wherein the wireless terminal calculates a data variation rate by comparing the transmission standby data with previous data transmitted on a previous cycle; and a step wherein the wireless terminal adjusts a transmission cycle in accordance with the data variation rate. According to the present invention, as the transmission cycle of a terminal forming an LPWA network is variously changed in accordance with a data variation rate, a reception time pattern and the like, the probability of a data collision caused by simultaneous reception in a gateway or the like can be significantly reduced. Therethrough, since a data loss rate is considerably lowered, the performance and management efficiency of an LPWA network can be improved to improve an overall service quality, and make network management more convenient.
