The Xiaomi Mi 4A Dual Band Wireless Router allows you to reach 300Mbps over the2.4GHz band and 867Mbps over the crystal clear 5GHz band, the max wireless speedis up to 1167Mbps over both. The 2.4GHz band offers transmission over greaterdistances, with better coverage and better penetration through walls, while the5GHz band adopts 802.11ac technology giving you less interference and higherspeeds for a smoother experience watching HD videos and playing multiplayeronline games.The Mi Router 4A supports Smart Connect, offering 2.4GHz and 5GHz bands underone Wi-Fi name. This allows you to have no more confusion over which Wi-Finetwork to connect to 2.4GHz and offers better performance through walls, while5GHz provides higher speeds. The optimal frequency band is also automaticallyselected by a dual-band terminal.The router comes with 4 external antennas so that the signal can travel throughwalls better. 4 external omnidirectional antennas, which are precision tested,and with a carefully designed internal structure and configuration greatlyimproves transmission performance, even in complex environments. It alsofeatures dual cooling fin heat sinks for better system stability and cooling. Aspecially treated metal substrate is combined with nanomaterials boastingexceptional thermal radiation features. It offers both excellent heat absorptionand heat dissipation capabilities to effectively lower the chip temperature andprovide improved system stability.FEATURES: * 4 external antennas * Dual-band wireless network * 64 MB memory for stable operation * Control remotely via the app * Unauthorized access prevention * Parental controlSPECIFICATIONS: * Processor: MT7628DA * Internal memory: 64MB * 2.4G Wi-Fi: 2x2 (supports the IEEE 802.11n protocol, maximum possible speed of 300Mbp * 5G Wi-Fi: 2x2 (supports the IEEE 802.11ac protocol, maximum possible speed of 867Mbps) * Product antennas: 4 external omnidirectional antennas (two 2.4GHz antennas with a maximum gain of 5dBi; two 5GHz antennas with a maximum gain of 6dBi) * Product heat dissipation: Natural heat dissipation * Total interfaces: Two 10/100M self-adaptive LAN ports (Auto MDI/MDIX), One 10/100M self-adaptive WAN port (Auto MDI/MDIX) * LED indicator lights: 2 * System reset buttons: 1 * Power input interface: 1 * Protocol standards: IEEE 802.11a/b/g/n/ac, IEEE 802.3/3u * Certification standards: GB9254-2008, YD/T993-1998, GB4943.1-2011 * Dual band: 2.4GHz and 5GHz * Modulation: 11b: DSSS: DBPSK (1Mbps), DQPSK (2Mbps), CCK (5.5/11Mbps), 11a/g: OFDM: BPSK (6/9Mbps), QPSK (12/18Mbps), 16QAM (24/36Mbps), 64QAM (48/54Mbps), 11n: MIMO-OFDM: BPSK, * QPSK, 16QAM, 64QAM.
