At some point, routers have stopped becoming a pure commodity device. Some manufacturers are differentiating themselves based on CPU performance or available RAM, while others compete on software features. In this case, TP-LINK is introducing two routers: one with four antennas, and the other with six. They are both designed around connection quality for multiple devices that are communicating simultaneously.
TP-LINK Archer C2600
The Archer C2600 is the four-antenna product that uses Qualcomm MU-MIMO EFX, which can connect to three devices at once. TP-LINK states that the platform can establish four connections, but they are reserving the fourth to assist the other three by somehow reducing interference. They do not provide details about their specific process (whether it's constructive interference, choose the best signal, etc.) and I do not have a deep understanding of practical implementations in this area.
TP-LINK Archer C3200
The Archer C3200 is the six-antenna SKU that can operate on three bands simultaneously. Rather than sharing a single chunk of the 5.0 GHz spectrum, or dropping some devices down to 2.4 GHz, it can manage two segments of 5.0 GHz simultaneously (and a third at 2.4 GHz). As the number of connected devices increase, the router will automatically assign them to the best block.
Both routers also include Gigabit Ethernet for wired networks, and USB 3.0 ports (they do not state how many) to attach storage to. The C3200 advertises “Substantial RAM” without providing any hard numbers.
No pricing information is currently provided, but they are expected to be available in Q3 2015.
