Network system and network device for coexistence of Wi-Fi HaLow network and low rate wireless personal area network (LR-WPAN)

摘要

A network system for coexistence of a Wi-Fi HaLow network and a low rate wireless personal area network (LR-WPAN) is a receiver for receiving a wireless signal in a frequency band shared with the LR-WPAN using the LR-WPAN protocol. A sensor for detecting an energy level of a wireless signal, a memory for storing a first program for performing an energy detection (ED) clear channel assignment (CCA) control process, and a first sensor in association with the sensor and the memory. A processor that executes a program to determine whether a packet is allowed to be transmitted based on the detected energy level of the wireless signal according to the ED CCA control process, and Wi if the ED CCA control process permits the transmission. -Fi HaLow A transmitter for transmitting the packet through the frequency band according to the protocol.
