Abstract

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