Home Wi-Fi and Networking Planning

In most Indian homes, the Wi-Fi router lives wherever the internet installer left it — usually on a shelf near the main door, where the fibre cable entered the flat, sometimes inside a wooden cabinet, occasionally behind the television. Within weeks the complaints begin: the video call drops in the far bedroom, the smart TV buffers, the CCTV camera on the terrace goes offline, and someone buys a plug-in extender that makes things only slightly better. The family assumes the internet plan is too slow. Very often the plan is fine; the problem is that radio signals cannot pass easily through the reinforced concrete and brick that Indian homes are built from.

Home networking has quietly become a building service, like electricity and plumbing. Work-from-home, online classes, streaming, video door phones, security cameras, smart switches and appliances all depend on it. Yet it is rarely shown on the electrical drawings, and when it is, it is often a single "data point" beside the TV. The result is retrofitting after the interiors are finished — surface-run cables, holes in new false ceilings, extenders in every socket. This article explains how to plan a home network properly at the design stage, with dimensions, cable rules, coverage logic and indicative October 2026 costs, so that it is done once and done right.

Why Wi-Fi struggles in Indian homes

Wi-Fi is radio. A router transmits on two or three frequency bands — 2.4 GHz, 5 GHz and, on newer equipment, 6 GHz — and every wall, slab, door and appliance between the router and a device absorbs or reflects part of that signal. The lower 2.4 GHz band passes through walls better but is slower and crowded by neighbours' networks; the higher 5 GHz and 6 GHz bands carry much more data but lose strength faster through obstacles. In a typical apartment tower, dozens of neighbouring networks also compete on the same channels.

Indian construction is unusually hard on Wi-Fi. Most homes have RCC slabs and beams, solid or hollow brick or block walls of 115–230 mm with cement plaster, and often a fair amount of steel and glass. Toilets add tiles and water pipes; kitchens add refrigerators and metal cabinets; wardrobes full of clothes and mirrors on doors add more loss. The table below gives a qualitative ranking from field experience; exact losses vary with frequency, thickness, moisture and reinforcement, so it should be read as relative guidance rather than measured values.

The practical conclusion is simple: in an Indian 2BHK or 3BHK flat, a single router can cover two or three rooms well. Beyond that, the signal has to pass through too many walls, and speeds in the far rooms fall sharply even when the bars on the phone look acceptable. In a two- or three-storey bungalow, a single router on the ground floor will struggle to serve the top floor at all. The answer is not a more powerful router — power is limited by regulation, and the phone or laptop must also transmit back — but more access points, closer to where people use them, connected to each other by cable wherever possible.

A short history of home networking

Home networking in India has followed the arrival of faster internet. Dial-up and early broadband needed only one computer beside the phone line. The first Wi-Fi standards around the turn of the century made a single router enough for a few laptops. Smartphones, streaming and fibre-to-the-home connections changed the load completely: a family of four may now have thirty or more connected devices, and the bottleneck has moved from the internet line to the home's own network. The Wi-Fi Alliance's generation names — Wi-Fi 4, 5, 6, 6E and 7, introduced in 2018 — make it easier to compare equipment.

For India specifically, the 6 GHz band has been the open question for several years. Rules notified in 2025 by the Department of Telecommunications opened the lower part of the band for licence-exempt low-power indoor use, which means Wi-Fi 6E and Wi-Fi 7 equipment can use 6 GHz indoors where the device firmware enables it for India. Because regional firmware and device support vary, the safe planning assumption is that 5 GHz will carry most traffic for the next few years and that 6 GHz will be a bonus in the room where an access point sits. That reinforces the main lesson: more access points, closer to the user.

Three ways to build a home network

There are three common architectures for whole-home Wi-Fi, plus the plug-in extender as a stop-gap. They differ in performance, in how much wiring they need, and in cost. The key distinction is the backhaul — the link that carries traffic from each Wi-Fi unit back to the main router. A wireless backhaul uses radio for that link and so spends part of the available capacity on it; a wired backhaul uses an Ethernet cable and leaves all of the radio capacity for devices.

For a new home, Aaditya Interior's recommendation is to wire for the last two options even if the family starts with something simpler. A Cat6 cable to the right ceiling or wall positions costs very little while the electrician is laying conduit, and it allows a mesh system with wired backhaul today and dedicated access points later. A home that is wired can always use wireless; a home that is not wired can never easily become wired once the false ceiling, wall finishes and furniture are in place.

Placing access points in a flat

An access point radiates broadly in all directions, a little like a light bulb. The best position is high, central to the rooms it serves, and in open space — typically on the ceiling of a passage or a living room, not inside a cabinet, not on the floor and not behind the television. A practical working rule for Indian brick-and-RCC homes is one access point for every two or three rooms, or roughly one for every 70–110 square metres of carpet area in an open layout and less in a heavily walled one. The figure below shows a typical 3BHK of about 120 square metres carpet area planned with two ceiling access points.

Several points in the plan are worth noting. The network niche sits near the entrance, where the fibre enters the flat, but it is a proper built-in space — not a shelf in the shoe cabinet. One access point covers the living–dining space and the kitchen; the second sits on the passage ceiling, from where it reaches all three bedrooms through only one wall each. Separate Cat6 runs reach the TV wall and the study desk, so the two devices that use the most data — the television and the work computer — do not depend on Wi-Fi at all. The bathroom and dressing area, lined with tiles and mirrors, are deliberately not used as a route for signal.

When the false ceiling is gypsum, a ceiling access point can be mounted directly on it with a backing plate, with the cable dropping from a junction box above. When there is no false ceiling, a small surface box on the RCC slab, fed from a conduit cast in the slab or run in a neat surface raceway, does the same job. In both cases it is worth placing the access point at least 300–500 mm away from large metal objects such as AC indoor units, ducts and light fittings with metal housings.

Duplexes and bungalows: one access point per floor, at least

An RCC slab is the strongest barrier a Wi-Fi signal meets in an Indian home. A router on the ground floor of a G+1 or G+2 bungalow may show a signal upstairs, but the usable speed is usually poor, and the terrace — where many families now want CCTV, a sit-out or a home gym — often gets nothing at all. The reliable approach is at least one access point on every floor, all wired back to a single network cabinet, with a vertical cable riser planned through the house.

In a bungalow, the network cabinet usually belongs under the staircase, in a store or in a utility room — somewhere central, dry and ventilated, with a short route to the riser. A vertical riser of two 25 mm conduits, or a dedicated shaft shared with low-voltage services such as CCTV and intercom, lets cables reach every floor. Gates, gardens and terraces can be covered by an outdoor-rated access point mounted under a projection or by a camera system on its own cable; both should be wired from the same cabinet so that the whole system shares a single power backup.

Cabling: Cat6, conduits and outlet positions

Structured cabling for homes uses the same standards as offices, simplified. Category 6 (Cat6) unshielded twisted-pair cable is the sensible minimum for new homes in 2026; it supports gigabit speeds comfortably over the full 100 m channel and 10-gigabit speeds over shorter runs (roughly up to 55 m depending on conditions). Category 6A supports 10 gigabits over the full 100 m and is worth considering for long runs in large villas or home offices, though it is thicker and stiffer to install. Each outlet should have its own continuous cable back to the cabinet — never a joint hidden in a wall box.

The conduit matters as much as the cable. Data cables should run in their own PVC conduit, never in the same conduit as mains wiring; this is both standard electrical practice under IS 732 and essential to avoid interference and safety risks. Where data and power conduits run in parallel, a separation of 50 mm or more is a commonly used rule of thumb, and crossings should be at right angles. A 25 mm conduit comfortably carries two or three Cat6 cables; bends should be gentle, with a pull box every few bends or every 10–15 m of run, so that the cable is not stretched or kinked during pulling.

How many data points does each room need?

The schedule below is a practical starting point for a 3BHK flat or a mid-size bungalow. It errs on the generous side, because a cable that is pulled during construction costs a fraction of one added later, and because spare points are the cheapest form of future-proofing. Each point is priced in line with the electrical layout article on this blog, at about ₹800–2,000 per data point at indicative October 2026 rates.

Designing the network niche

The network niche — called a network cabinet, rack or hub in larger homes — is where the fibre ends and the home network begins. In a flat it can be a dedicated compartment in the foyer or utility storage; in a bungalow it is usually a small wall-mounted cabinet under the stair or in a store. Whatever its form, it needs four things: space, power, ventilation and access. Routers and switches produce heat, the internet provider's optical network terminal (ONT) must stay reachable for service visits, and every cable from the house must arrive there neatly. The figure below gives a working size for a built-in niche.

In practice, the niche should be planned on the electrical drawing with its own circuit and on the interior drawings with its own shutter detail. A louvred or perforated shutter allows air to circulate and can be finished to match the foyer joinery. The internet provider's fibre usually enters near the main door, so the niche is best located close to that point; if it must be elsewhere, a conduit from the entry point to the niche should be provided so that the provider can pull the fibre or its drop cable through without surface wiring.

Power backup deserves special emphasis in India. The router, the switch, the access points and the ONT should all be on the inverter or backup circuit; otherwise every power cut takes down the internet, the cameras and any smart-home system that depends on them. A small dedicated UPS inside the niche gives clean power and covers the few seconds of changeover when an inverter switches over. With PoE access points, powering the switch is enough to keep all the access points alive, which is one of the quiet advantages of that architecture.

What a well-planned home network costs

Costs depend on the size of the home, the equipment level and how much cabling is done during construction. The table below gives indicative October 2026 ranges for a 3BHK flat of about 1,200–1,400 sq ft carpet area and for a G+1 bungalow. Equipment prices move quickly and vary by brand; the cabling figures are consistent with the per-point rates used for electrical work on this blog. Treat all figures as budgeting guides to be confirmed with a local electrician or network installer.

The figures show where the value lies. In a typical flat, proper cabling adds perhaps ₹10,000–20,000 to the electrical budget — a small fraction of a full interior — and turns every future equipment purchase into a simple swap. The expensive mistake is the opposite: buying premium equipment and then placing it in the wrong spot, or trying to compensate for missing cables with ever more powerful wireless units.

Security and management basics

A home network now carries cameras, door locks and children's devices as well as work laptops, so basic security belongs in the plan. Change the default administrator password on the router and every access point, and use WPA3 encryption where all devices support it (WPA2 with a strong passphrase otherwise). Set up a separate guest network for visitors and, where the equipment supports it, a separate network for smart-home and camera devices, so that a weakly secured gadget cannot be used to reach the family's computers. Keep firmware updated — many modern systems do this automatically — and keep a written record in the niche of the provider's details, the network names and where each cable runs. A labelled patch panel and a simple drawing of cable routes will save hours during any future repair or upgrade.

Where home networks are heading

Three trends are reshaping home networking. First, Wi-Fi 7 and the 6 GHz band push very high speeds into the room where an access point sits, which rewards homes with one access point per main space. Second, fibre connections at one gigabit and above are now common in Indian cities, and multi-gigabit plans are appearing; to benefit, the wiring inside the home must keep up, which is why Cat6 or Cat6A is the right choice today. Third, smart-home standards such as Matter and low-power meshes such as Thread reduce the number of devices that need Wi-Fi at all, while increasing the importance of a stable, always-on core network with power backup. In each case, the homes that adapt easily will be the ones with conduits, spare capacity and a proper network cabinet planned from the start.

Rules for planning a home network

• Draw the network on the electrical layout: niche, access points, data outlets and conduit routes, before any wall is plastered.
• Plan one access point for every two or three rooms in brick-and-RCC homes, and at least one per floor in duplexes and bungalows.
• Mount access points high and central — on a ceiling or at 2100–2400 mm — never inside cabinets, behind TVs or near AC units.
• Wire the TV, the work desk and every access point with Cat6 home runs; use Wi-Fi for phones and laptops that move.
• Run data in its own 25 mm conduit, never with mains wiring; cross power at right angles and keep about 50 mm apart in parallel runs.
• Keep every cable run within 90 m and free of joints; label both ends and record the routes.
• Build a ventilated network niche on the backup supply with at least four sockets and room for a switch and UPS.
• Buy Wi-Fi 6 at minimum for new equipment; consider Wi-Fi 7 in premium homes, and lay spare conduit for upgrades.
• Separate guest and smart-device networks from the family network and change all default passwords.

Frequently asked questions

Where is the best place to put a Wi-Fi router in a flat?

High and central, in open space, with as few walls as possible between it and the rooms it serves — typically a passage ceiling or a high wall in the living area. Avoid floors, closed cabinets, behind the TV, near mirrors and inside the kitchen. If the fibre enters at the main door, run a cable from there to the central position rather than leaving the router at the door.

Is mesh Wi-Fi better than an extender?

Usually yes. A mesh system gives one network name, hands devices between nodes more smoothly and manages channels automatically. A plug-in extender is a cheap fix for one dead room but typically halves speed on the repeated link. The best of both is a mesh system or access points connected by Cat6 cable (wired backhaul).

Do I need Cat6 cabling if I have good Wi-Fi?

For a new home, yes. Cables give the TV and work desk stable, full-speed connections, let access points or mesh nodes run at full capacity, and carry power to cameras and access points through PoE. Laying them during construction costs a fraction of retrofitting later.

Why is my Wi-Fi weak upstairs in a bungalow?

Because RCC slabs block much of the signal, especially on 5 GHz. Add an access point on each floor connected by cable to the main router, ideally through a vertical conduit riser planned near the staircase or in a service shaft.

How many devices can a home router handle?

It depends on the router, but many consumer routers start to struggle somewhere around 25–40 active devices. Wi-Fi 6 and newer equipment handles many devices more efficiently, and spreading devices across several access points helps further.
