Description

An electronic device performing NAN communication through the frequency band of a DFS channel and the frequency band of a NON-DFS channel, and a method of operation of the electronic device The present disclosure relates to an electronic device and a method of operating the electronic device, and more specifically to an electronic device that performs NAN communication through a frequency band of a DFS channel and a frequency band of a non-DFS channel. With the proliferation of various electronic devices, speed improvements for wireless communication usable by these devices have been realized. In addition, various types of proximity services utilizing low-power discovery technology are being developed recently. For example, proximity services (or proximity communication services) are being developed that allow electronic devices in close proximity to rapidly exchange data through a proximity network. Proximity services may include low-power proximity services using BLE (Bluetooth low energy) beacons, or low-power proximity services based on low-power short-range communication technology based on wireless LAN (WLAN) (e.g., NAN (neighbor awareness networking), Wi-Fi aware) (hereinafter referred to as 'NAN'). According to one embodiment, a NAN-based low-power proximity service (hereinafter referred to as the "proximity service") represents a service that utilizes a proximity network that changes dynamically according to the movement of electronic devices, and a set of electronic devices that form the proximity network may be referred to as a cluster. In the case of the proximity service, electronic devices included within the cluster may transmit and receive a discovery signal (e.g., a beacon) and a service discovery frame (SDF) (hereinafter referred to as the "SDF") within a time duration (or communication period) that is synchronized with each other. For example, at least one electronic device within the cluster may transmit a signal to announce the existence of the cluster, and a new electronic device intending to join the cluster may receive the signal. Each electronic device within a cluster can set a different active duration for transmitting and receiving signals to reduce current (or power) consumption. In NAN communication, the active duration for transmitting and receiving signals can be referred to as the discovery window (DW). Additionally, electronic devices included in the cluster can reduce current consumption by maintaining a low-power state (e.g., sleep state) during periods other than the discovery window. Recently, electronic devices supporting short-range wireless communication can support the performance of short-range wireless communication using channels with relatively low congestion (or channel occupancy). According to one example, the electronic device can perform short-range wireless communication using a dynamic frequency selection (DFS) channel. Dynamic Frequency Selection (DFS) refers to a technology that enables short-range wireless communication through DFS channels, which are used for various purposes (e.g., military or weather observation). DFS channels may have relatively lower congestion (or channel utilization) compared to other channels, and the performance of short-range wireless communication via DFS channels can be higher than that via other channels. There is a growing trend to apply short-range wireless communication using DFS channels to various applications. FIG. 1 is a block diagram of an electronic device according to one embodiment.
