Using wireless networks (Wi-Fi)

Wireless routers and PCs emit electromagnetic radiation

Wi-Fi wireless routers and a PC wireless network cards emit electromagnetic radiation all the time, even when there is no data being transferred on the wireless network. When the amount of data transferred on the network will increase, the radiation levels both from the router and the wireless PC will increase.  When the amount of data transferred will be big, the high to medium levels of electromagnetic radiation will be measured next to the wireless router and PC.  The exposure levels will be determined by the time of exposure and the levels of electromagnetic radiation.  When the levels of radiation will be higher (a lot of data, and close proximity to the source) and the time spend next to the source will be higher, so will the level of exposure (higher). In most wireless PC and laptops, when the wired network cable will be connected the wireless transmission will stop, but not in all cases. If there is software that is defined to use the wireless network card at all times, the PC wireless network card will continue to transmit and to radiate even when the wired cable will be connected. In wireless routers the wireless transmission will not be turned off automatically if a wired cable is connected. In some wireless routers it is possible to turn off the wireless option using a special button on the back or using the router GUI (HTML interface).


Using the wireless network (Wi-Fi) wisely!


In many houses there is a Wi-Fi router which is part of the home computer network. Wi-Fi routers emit high frequency electromagnetic radiation when the Wi-Fi option in them is turned on. In some houses the Wi-Fi wireless network is the only computer network in the house. In some houses there is also a wired network, which is much safer, faster and reliable. 

Most of the laptops that are sold and used today have a Wireless connectivity via Wi-Fi or Bluetooth; some of them even have a 3G cellular network modem, built in or added. 

In order to limit your exposure to electromagnetic radiation it is better to keep the Wi-Fi option on your router and all the wireless connectivity devices on your laptop turned off when not in use. 

When possible it is better to use a wired network connection. 

In all laptops and most Wi-Fi routers there is a button or an easy to turn the wireless devices off, but most people don't know how to do it, and leave if on all the time and by that exposing themselves to electromagnetic radiation when there is no real need. All you need is a quick look at the user manual and you can do the easy steps. In some routers you can also set the strength level of the Wi-Fi signal. 

** Connecting a desktop to the wireless network is not recommanded at all times.

*** We recommand to use wireless network only when there is no other option, if possible not using it at all.
