Wireless Communication Protocol Support
IEEE 802.11 Standards Compliance: It fully complies with IEEE 802.11b/g/n standards, which means it can operate in the 2.4GHz frequency band and provide wireless data transmission with different modulation and coding schemes corresponding to each standard. For example, in 802.11b mode, it uses DSSS (Direct Sequence Spread Spectrum) modulation with CCK (Complementary Code Keying), DQPSK (Differential Quadrature Phase Shift Keying), and DBPSK (Differential Binary Phase Shift Keying) modulation methods; in 802.11g/n mode, it uses OFDM (Orthogonal Frequency Division Multiplexing) modulation with BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying), 16QAM (16 Quadrature Amplitude Modulation), and 64QAM (64 Quadrature Amplitude Modulation) modulation methods.
High-Speed Wireless Transmission: It supports a maximum wireless transmission rate of up to 150Mbps in 802.11n mode, enabling fast data transfer between devices, which is suitable for applications requiring high-speed wireless data transmission such as video streaming, online gaming, and large file downloads.
Network Connection and Management
Infrastructure and Ad-Hoc Modes: It can work in both infrastructure mode and ad-hoc mode. In infrastructure mode, the device can connect to an existing wireless access point to access the local area network or the Internet; in ad-hoc mode, the device can directly communicate with other wireless devices without the need for an access point, forming a peer-to-peer wireless network.
Security Protocol Support: It provides support for multiple wireless security protocols, including 64/128-bit WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access)/WPA2, and WPA-PSK (Pre-Shared Key)/WPA2-PSK (TKIP/AES). These security mechanisms can effectively protect the security of wireless network connections and data transmission, preventing unauthorized access and data leakage.
Power Management
Low Power Consumption: It is designed with a low-power architecture, which can significantly reduce power consumption during device operation, thereby prolonging the battery life of portable devices or reducing the power consumption of the entire system. For example, in sleep mode, the power consumption is extremely low, and it can quickly switch to the active state when needed to receive and transmit data.
System Compatibility and Integration
Wide Voltage Range: It can operate with a supply voltage range of 2V to 6V, which makes it suitable for various power supply systems, whether it is a battery-powered portable device or a device with a stable power supply, it can work normally.
Interface Compatibility: It has a standard interface, which can be easily connected and integrated with other chips or devices, such as microcontrollers, and is convenient for system designers to develop various wireless application solutions.
