The physics of where to put a WI-FI ROUTER: Scientist proves that the centre of your home is best for signal strength
Jason Cole at Imperial College London simulated Wi-Fi router locations
Through complex equations he proved the centre of a home was the best place for optimum connection
He had been frustrated by blackspots in his flat when accessing the internet
Walls, doors and corners were found to greatly decrease signal strength
His simulation found there was no substitute for line-of-sight to the router
While he has not tried the simulation in the real world yet, he tells MailOnline some people have suggested ‘taping an antenna to a robot vacuum cleaner’
Deciding where to place a Wi-Fi router at home to minimise signal blackspots is a fine art.
But a physicist has attempted to tackle the problem by mathematically working out the optimum position for a router.
He studied how walls and reflections affected signal strength and concluded that, as common sense might suggest, there’s just no beating the centre of a house for router location.
Jason Cole at Imperial College London simulated Wi-Fi router locations (shown above in the diagram of Mr Cole’s flat). He found that the best location, as common sense might suggest, was in the centre of a home. He had grown frustrated after finding blackspots in his flat
The ‘complex’ research was carried out by Jason Cole, a PhD physics student at the John Adams Institute at Imperial College London.
ARE WI-FI SIGNALS DANGEROUS?
Wi-Fi signals use very low intensity radio waves. Whilst similar in wavelength to domestic microwave radiation, the intensity of Wi-Fi radiation is 100,000 times less than that of a domestic microwave oven.
The type of radiation emitted by radio waves (Wi-Fi), visible light, microwaves and mobile phones has been shown to raise the temperature of tissue at very high levels of exposure – but that’s much higher than what people are subjected to on a regular basis.
This is called a thermal interaction, but researchers are divided as to whether the radiation we receive daily can cause damage.
The UK Health Protection Agency (HPA) has been monitoring the safety of Wi-Fi. It says people using Wi-Fi, or those in the proximity, are exposed to the radio signals it emits – and some of the transmitted energy in the signals is absorbed in their bodies.
However, the signals are very low power. Sitting in a Wi-Fi hotspot for a year results in receiving the same dose of radio waves as making a 20 minute mobile phone call.
