Another key feature is Target Wake Time (TWT), which allows devices to schedule specific times to wake up and communicate with the router, thus minimizing power consumption and extending battery life for IoT devices and wearables that rely on low-power connectivity.
On the Bluetooth side, the MT7902BEN/A supports Bluetooth 5.2, which enhances the overall Bluetooth experience by providing faster data rates, longer range, and LE Audio support for wireless audio devices. The chip also features Bluetooth Low Energy (BLE), making it highly suitable for IoT applications, where energy-efficient, continuous communication is essential for devices like smart thermostats, fitness trackers, and smart lights.
Furthermore, the chip's advanced power management ensures that it maintains low energy consumption during idle periods, extending battery life for portable and remote devices. The integration of Wi-Fi 6 and Bluetooth 5.2 within a single chip provides a comprehensive and efficient wireless solution for modern applications, offering both high-speed data transmission and low-power operation in a compact, versatile design.
In summary, the MediaTek MT7902BEN/A is an exceptional choice for devices requiring high-speed wireless connectivity and long-lasting battery life, making it an ideal solution for smartphones, tablets, IoT devices, smart home applications, and wireless audio systems. Its combination of Wi-Fi 6 and Bluetooth 5.2 features ensures seamless and efficient performance in diverse and high-demand environments.
Specification
Wi-Fi Specifications:
Wi-Fi 6 (802.11ax): The MT7902BEN/A supports Wi-Fi 6 (802.11ax), the latest Wi-Fi standard, which offers significant improvements in network efficiency, speed, and latency. With 802.11ax, it can deliver higher throughput and better performance, particularly in environments with multiple connected devices. Wi-Fi 6 can provide speeds up to 2.4 Gbps (depending on the router and environment), with better performance in congested areas.
2x2 MIMO (Dual Spatial Streams): The 2x2 MIMO technology enables two spatial streams for both transmitting and receiving data, improving the overall speed and efficiency of wireless communication. This allows multiple devices to communicate simultaneously without degrading performance. The support for 2x2 MIMO ensures better throughput and reduced latency, which is ideal for high-bandwidth applications such as 4K video streaming, gaming, and large file transfers.
OFDMA (Orthogonal Frequency Division Multiple Access): The MT7902BEN/A leverages OFDMA, a key feature of Wi-Fi 6, to further improve network efficiency. OFDMA allows multiple devices to share the same channel by dividing the channel into smaller sub-channels, which reduces congestion and lowers latency. This is especially beneficial in dense environments like offices or crowded public spaces.
Target Wake Time (TWT): The Target Wake Time (TWT) feature enables devices to schedule specific times to wake up and transmit data. This reduces the power consumption of devices, making it highly beneficial for IoT devices and battery-powered devices such as smart home sensors or wearables. By synchronizing the wake-up times, it minimizes the need for constant channel access, thus optimizing energy efficiency.
Bluetooth Specifications:
Bluetooth 5.2: The MT7902BEN/A integrates Bluetooth 5.2, which introduces significant improvements over Bluetooth 5.0, including longer range (up to 4x compared to Bluetooth 4.2) and faster data transfer (up to 2 Mbps). This enhances Bluetooth connectivity in both smart home devices and wireless audio devices, providing higher-quality connections and more stable performance over longer distances.
Bluetooth Low Energy (BLE): The chip supports Bluetooth Low Energy (BLE), which is optimized for low-power, intermittent communication. BLE is essential for IoT applications, including smart lights, wearables, fitness trackers, and health-monitoring devices, as it allows devices to maintain constant connections while conserving battery life.
LE Audio & Audio Sharing: Bluetooth 5.2 supports LE Audio, which enables better sound quality and lower power consumption for audio devices such as wireless headphones and smart speakers. LE Audio also enables audio sharing, allowing a single source device to stream audio to multiple audio receivers at once, which can be a great feature for shared listening experiences or multi-room audio systems.
Power Efficiency:
Advanced Power Management Features: The MT7902BEN/A includes a range of power management technologies, which help optimize the chip’s energy consumption, making it suitable for battery-powered devices. These technologies include dynamic power adjustment, low-power sleep modes, and intelligent switching between Wi-Fi and Bluetooth based on workload, ensuring that the chip consumes minimal power during idle periods while maintaining high performance when necessary.
Power Saving with Wi-Fi 6: The chip takes full advantage of Wi-Fi 6’s Target Wake Time (TWT) feature, which helps devices schedule their communication times, allowing them to remain in low-power states for longer periods. This is especially beneficial for IoT sensors and smart home devices that do not need to be constantly transmitting data.
Energy-Efficient Bluetooth 5.2: The Bluetooth Low Energy (BLE) and Bluetooth 5.2 features of the MT7902BEN/A are designed to maintain a constant, low-power connection with devices like wearables, fitness trackers, and smart home devices. These features allow devices to stay connected without draining battery life, providing longer battery life for portable or remote devices.
Other Features:
Backward Compatibility: The MT7902BEN/A is backward compatible with earlier Wi-Fi and Bluetooth versions, ensuring it works with a wide range of legacy devices. It supports Wi-Fi 5 (802.11ac), Wi-Fi 4 (802.11n), and earlier Bluetooth standards, allowing the chip to be used in existing networks and ecosystems, making it a versatile solution for upgrading devices to Wi-Fi 6 and Bluetooth 5.2.
Enhanced Network Capacity: By supporting Wi-Fi 6, the MT7902BEN/A improves the network capacity significantly, making it ideal for environments with many connected devices, such as smart homes and office environments. Wi-Fi 6 can handle more devices simultaneously, reducing network congestion and ensuring stable connections for all devices, from smartphones to IoT appliances.
