Netgear on Monday announced the Orbi WiFi System, designed to eliminate dead spots in smart homes. Orbi's system "is similar to using a network extender, but Netgear has improved on this approach with a dedicated band for communication with the satellite devices," explained Bill Ablondi, a research director at Strategy Analytics. An Orbi WiFi system consisting of one router and one satellite can cover a home of up to 4,000 square feet in area. The initial Orbi system will be available in September for $400.
