Fastest Wi-Fi standard: 802.11acThe PCE-AC68 uses Broadcom''s new 5th generation Wi-Fi 802.11ac chipset to reach speeds of up to 1.3Gbit/s through the 5GHz band, which is three times faster than 802.11n Wi-Fi. At the same time, it maintains full backward compatibility with all previous Wi-Fi protocols, providing high performance two-way transmission while ensuring a smooth transition to 802.11ac and seamless interconnection with existing devices.Next-generation Wi-Fi on both bands!Broadcom TurboQAM™ hardware integrated on the PCE-AC68 brings the speed benefits of next-generation 802.11ac Wi-Fi to both 2.4GHz and 5GHz bands. At 600Mbit/s and 1.3Gbit/s respectively, they turn the PCE-AC68 into a formidable AC1900 wireless adapter, providing speeds that cannot be bettered by generic wireless adapters. Connect the PCE-AC68 to ASUS networks to attain the very highest possible Wi-Fi speeds.
