The Mercusys MA30E is a PCIe wireless adapter designed to bring high-speed internet and wireless connectivity to your desktop computer. By utilizing the AC1200 standard, it provides dual-band support with speeds of up to 867 Mbps on the 5 GHz band and 300 Mbps on the 2.4 GHz band, allowing you to handle different online tasks across two frequencies. The inclusion of MU-MIMO and OFDMA technologies helps manage data traffic more efficiently, which is particularly useful when multiple devices are active on your network. This black adapter features two fixed high-gain omni-directional antennas to ensure a stable signal throughout your workspace. For added versatility, it includes Bluetooth 5.0, though you will need to connect the provided header cable to your motherboard's USB 2.0 port to enable this feature. Security is handled by the WPA3 protocol, keeping your connection protected against modern threats. Designed for users running Windows 10 or 11 (64-bit), the card measures 226.3 x 120.8 x 21.5 mm. Please note that it is not compatible with low-profile brackets, so it is best suited for standard-sized PC towers. It operates reliably within a temperature range of 0 °C to 40 °C, making it a dependable choice for a home or office setup.
