Sila is a three stream tri-band 802.11ac router (AC3000 class) with Gigabit Ethernet WAN (1) and LAN (4) ports and one each USB 2. 0 and 3.0 ports. The spec link rates look like it sports two-stream 2.4 GHz and 5 GHz radios and a second four-stream 5 GHz radios with maximum link rates of 400 Mbps, 866 Mbps and 1734 Mbps, respectively.
Sila has the gaming application optimized QoS you'd expect on a gaming router and the extra 5 GHz DFS channels should help buyers find a quieter space beyond their neighbors' network reach. It also supports MU-MIMO, "intelligent active (band) steering" and can form mesh networks if you pony up for more than one Sila.
Razer partnered with Ignition Design Labs, maker of the Portal router [reviewed] that IDL introduced at CES 2017. IDL had hoped its Multi-Channel Zero-Wait DFS technology would set the Wi-Fi world on fire with its ability to eliminate the 30 minute waiting period required after vacating a DFS channel when radar was detected.
You can still buy Portal, but Sila is the only other consumer router I've seen powered by IDL technology (which in turn runs on a Qualcomm platform).
Speaking of buying, you can do that for Sila too, by visiting Razer and forking over $249.99.
