The MT7915 chipset is a Wi-Fi 6 (802.11ax) chip that offers 2x2 MIMO technology and can deliver up to 1.2Gbps of wireless data throughput on the 5GHz band. It supports 1024-QAM modulation and MU-MIMO, which allows multiple devices to connect to a single access point and stream data simultaneously. The MT7915 chipset also supports OFDMA, which improves wireless efficiency and reduces latency, making it ideal for real-time applications such as gaming and video streaming.

The MT7975 chipset, on the other hand, is designed for high-end routers and access points. It offers 4x4 MIMO technology and can deliver up to 3.5Gbps of wireless data throughput on the 5GHz band. The chipset also supports MU-MIMO and OFDMA, allowing it to handle multiple devices simultaneously and improve wireless efficiency. The MT7975 chipset is compatible with Wi-Fi 6E (802.11ax) and can operate on the newly available 6GHz band, providing additional spectrum for high-bandwidth applications.

Both chipsets support the 2.4GHz and 5GHz frequency bands and are backward compatible with earlier Wi-Fi standards such as 802.11ac/a/b/g/n. They also support a range of technologies, including Spatial Multiplexing, Cyclic-Delay Diversity (CDD), Low-Density Parity Check (LDPC) Codes, Maximal Ratio Combining (MRC), and Space Time Block Code (STBC), which enhance wireless performance and reliability.

The Media Tek MT7915 and MT7975 chipsets are designed to meet the high demands of modern wireless connectivity. They offer advanced features such as beamforming, which focuses wireless signals on specific devices, and Target Wake Time (TWT), which reduces power consumption by allowing devices to schedule their wireless transmissions.

These chipsets are also designed with security in mind, supporting WPA3, the latest wireless security protocol, which offers improved encryption and authentication.
