Linksys unveils new top-end 802.11ac Wi-Fi router
Linksys unveiled a new top-end Wi-Fi router--likely the company's most powerful to date. The WRT1900AC is a dual band Wi-Fi router that sports a dual-core 1.2GHz ARM processor under the hood, topped by 128MB of flash memory and 256MB of DDR3 RAM. Other top-end specifications include an eSATA/USB 2.0 port, a USB 3.0 port, a four-port gigabit Ethernet switch and a gigabit WAN port. As expected, the USB ports can be connected to a USB storage device or a USB printer.
Visually, what stands out the most about the WRT1900AC is that it comes with four separate antennas. Under 802.11n, these allow the wireless router to support a theoretical speed of 600mbps on the 2.4GHz band. An on adapter card has to be used, however, as there are no laptops out there that support 600Mbps 802.11n throughput.
When it comes to 802.11ac though, the WRT1900AC is only capable of three spatial streams, which translate to a physical link rate of 1.3Gbps on the 5GHz band. This is due to the chipset Linksys chose, which means the feature cannot be added via firmware. For 802.11ac devices, the Wi-Fi router will choose the three antennas that deliver the best performance, and shut off the fourth one. Linksys says the WRT1900AC will be priced at $300.
