Portal is a QCA-based AC2350 / 2400 MU-MIMO enabled router with a dedicated radio module and cloud service that enables "zero wait" DFS channel switching. It was previewed at CES 2016 and its Kickstarter campaign launched this May.
Portal is no longer unique in its support of quick reuse of DFS channels in a consumer router. Linksys' recently announced WRT3200ACM also supports DFS channels and has a dedicated 5 GHz monitor radio to allow rapid reuse of channels when radar activity is detected.
Portal's price has increased from its $149 Kickstarter run, being listed for $199 on Amazon. The product is expected to start shipping in November.
