Most homes have a Wi-Fi router broadcasting continuously, 24 hours a day, whether anyone is online or not. Because that signal radiates outward in all directions, where you place the router has a surprisingly large effect on how much radiofrequency (RF) energy reaches the spots where you actually spend your time — your desk, your sofa, your bed. The good news is that thoughtful placement costs nothing, and pairing it with a shielding enclosure can lower ambient exposure even further.
This guide walks through the practical principles of router placement for a lower-EMF home, the rooms to prioritise, and where a router guard Faraday cage fits into the picture.
Why router placement matters
RF signal strength falls off rapidly with distance — roughly following the inverse-square law, meaning that doubling your distance from the router cuts the power density to about a quarter. In everyday terms, a router sitting 30 cm from your pillow exposes you to far more RF than the same router placed 4 metres away across the hall. Distance is the single cheapest and most effective lever you have.
It’s worth keeping this in perspective. The World Health Organization and its International Agency for Research on Cancer (IARC) classify RF electromagnetic fields as “possibly carcinogenic to humans” (Group 2B), a precautionary category that reflects limited evidence rather than established harm. Many people simply prefer to reduce avoidable exposure where it’s easy to do so — and router placement is one of the easiest.
The core placement principles
1. Maximise distance from where you sleep and sit
Identify the two or three places you occupy for the longest continuous periods — almost always the bedroom and your main work or relaxation seat. Position the router as far from those as your cabling allows. A router in a central hallway or utility area often serves the whole home well while keeping its strongest near-field away from your body.
2. Keep it out of the bedroom entirely
You spend roughly a third of your life asleep, in one fixed position, making the bedroom the highest-value room to protect. If at all possible, no router, mesh node, or smart hub should live in a bedroom. If your only phone socket is in a bedroom, consider relocating the line or using a longer cable to move the router into an adjacent space.
3. Mount it high and in the open — then shield it
Routers perform best with a clear line of sight, which is why people place them high on shelves. The trade-off is that an unobstructed router also radiates freely into the room. This is precisely the situation a router guard is designed for: a conductive mesh enclosure attenuates the RF radiating from the sides and top while still allowing enough signal through the apertures to keep your network usable.
4. Avoid reflective corners and metal surfaces nearby
Placing a router in a tight corner or directly on a metal filing cabinet can create uneven, concentrated reflections. A more open position on a wooden shelf produces a more even, predictable signal pattern.
Room-by-room priorities
If you can’t relocate the router far from everything, prioritise in this order:
- Bedrooms — highest priority. Long, stationary exposure during sleep.
- Home office / main desk — second priority, especially if the router sits within arm’s reach all day.
- Children’s rooms and nurseries — many parents treat these as equal to the main bedroom.
- Living room sofa — moderate priority depending on hours spent there.
Where a router guard fits in
Placement reduces exposure through distance; a router guard reduces it at the source. For a router you can’t move far enough away — say, an all-in-one ISP gateway tethered to a fixed socket in the room you use most — an enclosure is often the more practical fix. The Router Guard Faraday Cage Large is sized for bulky ISP gateways with external antennas, while the Router Guard Faraday Cage Small fits most standard domestic routers from providers like BT, Sky, Eero, and Linksys.

A simple weekend plan
- Walk your home and note where you spend the most stationary hours.
- Relocate the router as far from those spots as your cabling allows — ideally out of all bedrooms.
- Mount it in an open position rather than a tight metal corner.
- If it must stay close to where you sleep or work, fit a correctly sized router guard.
- Optionally, switch the router’s Wi-Fi off overnight using its built-in scheduler or a simple plug timer.
Frequently asked questions
Does moving my router really make a measurable difference?
Yes. Because RF power density drops with the square of distance, even moving a router a few metres further from your bed or desk produces a meaningful reduction in the exposure at that spot. An RF meter will show the difference clearly.
Will placing the router far away hurt my Wi-Fi coverage?
A central, elevated, open position usually improves whole-home coverage rather than harming it. If a single router can’t reach every room from a central spot, a wired access point in a distant room is preferable to keeping the main unit beside your bed.
Is a router guard better than just moving the router?
They solve the problem in complementary ways. Distance is free and always worth doing first; a router guard helps when distance alone isn’t enough or the router can’t be moved. Many people use both together.
