This version of Bluetooth also supports enhanced data transfer rates (up to 2 Mbps) and greater range (up to 4 times the range of Bluetooth 4.2). These improvements ensure faster and more reliable connections for wireless accessories, fitness trackers, and other Bluetooth-enabled devices.
Power management is another key feature of the MT7921LEN/B. The chipset is designed with energy efficiency in mind, using technologies like TWT (Target Wake Time) to schedule when devices wake up to transmit or receive data, reducing the amount of time spent in active transmission and extending battery life. This is particularly useful for portable devices such as laptops and smartphones, where maintaining long-lasting battery performance is critical.
The chipset’s PCIe 2.0 interface ensures fast communication with the host system, ensuring low-latency connections and high-speed data transfers, making it suitable for devices with demanding connectivity requirements. Whether installed in a laptop, tablet, or desktop, the MT7921LEN/B offers robust connectivity that enhances user experiences in multimedia, gaming, and other data-intensive applications.
For users concerned about network security, the MT7921LEN/B supports WPA3 encryption, offering improved security protocols over previous versions. This ensures that both personal and business networks are protected against unauthorized access, ensuring the safety of sensitive data.
Overall, the MediaTek MT7921LEN/B offers a compelling combination of Wi-Fi 6, Bluetooth 5.2, and energy-efficient design, making it an excellent choice for modern mobile devices, laptops, desktops, and other connected products. Its high-speed wireless capabilities, multi-device handling, and enhanced power efficiency make it a solid solution for users seeking reliable and fast connectivity in a wide range of environments.
Specification
Wi-Fi 6 (802.11ax):
Wi-Fi Standard: The MT7921LEN/B is a Wi-Fi 6 (802.11ax) solution that offers significant improvements over previous Wi-Fi generations, such as 802.11ac (Wi-Fi 5). Wi-Fi 6 provides higher data throughput, lower latency, and improved performance in environments with multiple connected devices, making it ideal for modern home networks, office setups, and public hotspots.
Dual-Band Operation: It supports dual-band operation on both the 2.4 GHz and 5 GHz bands, allowing devices to connect on either frequency for optimal performance depending on the environment. The 2.4 GHz band is better suited for longer-range connectivity, while the 5 GHz band offers higher speeds but a shorter range.
Data Throughput: Wi-Fi 6 supports up to 2.4 Gbps (using 160 MHz channel bandwidth), offering a significant boost in data throughput compared to Wi-Fi 5. This enables fast internet speeds, efficient video streaming, high-speed downloads, and better overall network performance even in crowded environments.
Bluetooth 5.2:
Bluetooth Version: The MT7921LEN/B integrates Bluetooth 5.2, which offers several enhancements over previous Bluetooth versions. Bluetooth 5.2 introduces LE Audio (Low Energy Audio), which improves audio quality and extends battery life for Bluetooth devices like headphones, earphones, and speakers.
Improved Data Transfer: Bluetooth 5.2 increases the maximum data transfer speed to 2 Mbps (compared to 1 Mbps in Bluetooth 5.0), allowing faster file transfers and smoother communication between Bluetooth-enabled devices.
Range and Power Efficiency: With Bluetooth 5.2, devices can achieve up to 4 times the range of Bluetooth 4.2, improving connection stability and usability in environments where the Bluetooth connection needs to cover a larger area. Additionally, Bluetooth 5.2’s improved power efficiency ensures that devices can maintain long-lasting connections without excessive battery consumption.
Power Management and Efficiency:
Advanced Power Save Mode: The MT7921LEN/B is equipped with advanced power-saving features, such as TWT (Target Wake Time), which allows devices to manage when they wake up to send or receive data, helping to conserve battery life.
Energy-Efficient Operation: Wi-Fi 6 and Bluetooth 5.2 are designed with power efficiency in mind. By improving wireless transmission efficiency, the MT7921LEN/B can reduce overall energy consumption, allowing devices to offer longer battery life, which is particularly important for portable devices such as laptops, smartphones, and tablets.
Low Power Consumption: In idle states or when connected to networks with minimal data traffic, the MT7921LEN/B consumes less power, ensuring that the device remains power-efficient even when not in active use.
Multi-Device Handling:
The MT7921LEN/B is built to handle multiple devices on the same network simultaneously, thanks to OFDMA (Orthogonal Frequency Division Multiple Access) and MU-MIMO (Multi-User, Multiple Input, Multiple Output) technology.
OFDMA allows the chipset to split the Wi-Fi channel into smaller sub-channels, enabling efficient communication with multiple devices at once, thereby improving overall throughput and reducing latency in crowded networks.
MU-MIMO allows the MT7921LEN/B to communicate with multiple devices simultaneously, improving the network experience for users with multiple devices connected at the same time.
Security Features:
The MT7921LEN/B supports WPA3 encryption, which is the latest Wi-Fi security standard, ensuring robust protection against cyber threats such as hacking and unauthorized access. WPA3 provides stronger encryption protocols compared to its predecessor WPA2, making it more secure for both personal and business use.
The chipset also supports WPA2, allowing it to be compatible with older Wi-Fi networks while providing the flexibility to connect to both legacy and modern networks securely.
Interface and Connectivity:
The MT7921LEN/B uses an PCIe 2.0 interface, which allows for fast communication between the wireless chipset and the host device (such as a laptop or smartphone). PCIe 2.0 offers sufficient bandwidth for both Wi-Fi and Bluetooth functions while maintaining low latency.
It integrates seamlessly into devices with PCIe or USB interfaces, making it suitable for a variety of form factors, from laptops and desktops to tablets and smartphones.
The chipset supports Windows, Linux, and Android platforms, ensuring wide compatibility with different operating systems.
Form Factor and Integration:
The MT7921LEN/B is typically available in an M.2 2230 form factor, which is a small, compact module that fits into modern laptops, tablets, and other portable devices with limited internal space. The small size of the M.2 form factor makes it suitable for ultrathin and lightweight devices that require high-performance wireless connectivity.
In addition to M.2 2230, MediaTek also offers versions of this chipset in other form factors such as mini-PCIe and USB dongle options, providing flexibility for integration into various device designs.
