How Many Access Points Does Your Home Actually Need?

The most common question we get before a WiFi install is "how many nodes do I need?" — and the honest answer is that square footage alone does not tell you. Two homes of the same size can need very different setups depending on their layout. What actually determines coverage: the number of floors, how many walls (and what they are made of — concrete cuts signal far more than drywall) sit between rooms, and where your smart devices physically live. A 2BHK apartment on one floor might need just a router and one satellite node. A multi-floor villa with a detached garage or outdoor security cameras usually needs a node per floor plus outdoor-rated coverage for anything outside. As a rough starting point: one router node comfortably covers up to roughly 2,000 sq ft in open layouts, and each additional satellite node extends that by a similar radius, with some overlap needed at the edges so devices can roam without a gap. Concrete walls, mirrors and large appliances all shrink that radius, which is exactly why a plan based purely on square footage tends to under-provision. This is why every GharIT WiFi install starts with a free on-site survey rather than a generic package: we walk the home, check signal strength room by room, and place nodes based on where your devices — and you — actually are.
