AC1200 class dual-band Wi-Fi MESH system designed to organize a seamless Wi-Fi 5 (802.11ac) wireless network in large residential areas, multi-room apartments, one- or two-story houses. The total serviced area can reach an impressive 260 m2 and the system can be easily scaled up by adding new units if necessary. Unlike wireless networks created on the basis of conventional routers or repeaters, the TP-LINK Deco M4 (2-pack) MESH system provides intrasystem roaming of devices completely invisible to the user and does not require complex configuration (the user can perform all operations for configuring it independently , using the application for Deco, which works on all current models of smartphones running Android or iOS).

The package includes two blocks, each of which is equipped with two Gigabit LAN / WAN ports with automatic detection. The right choice of a place for installing the blocks allows you to solve the problem of "dead" zones, increase the stability of connections and refuse to lay a network cable. The system is capable of providing high peak wireless data rates (up to 300 Mbps at 2.4 GHz and up to 867 Mbps at 5 GHz).
