The NETGEAR Orbi RBK863SB is a premium 3-pack WiFi 6 mesh system specifically engineered to tackle the connectivity challenges of large Indian residences. With a massive coverage area of up to 8,000 sq. ft., this AX6000 tri-band system is the ultimate solution for 4BHK apartments, independent bungalows, and multi-floor duplexes where thick RCC (concrete) walls typically kill signal strength. It delivers blazing speeds of up to 6 Gbps, making it the perfect companion for high-tier fiber plans from Jio Fiber, Airtel Xstream, and ACT Fibernet. The system features a 10Gbps Internet port, future-proofing your home for the next generation of ultra-fast internet. Unlike standard routers, the Orbi 860 series uses a patented dedicated wireless backhaul, ensuring that even when you are multiple walls away from the main router, your speeds remain consistent for 4K streaming on Hotstar or lag-free gaming in BGMI. Designed to handle up to 100 devices simultaneously, it incorporates OFDMA and MU-MIMO technologies to manage the modern Indian smart home—from smart TVs and laptops to WiFi-enabled ACs and security cameras. The sleek black aesthetic blends perfectly with modern Indian interiors, and the comprehensive Orbi app makes setup and parental controls simple for every user.
