Eco-wifi: 90% reduced pulse frequency

Even when the Eco-wifi router is in use, with devices connected, it emits less radiation than an ordinary wifi router. The Eco-wifi router has a 10x reduced beacon pulse frequency. This is explained below.

Any wifi router transmits two main types of packets:

  1. Beacon packets containing the name of the wifi network. The largest problem is, that in ordinary wifi routers, these are transmitted 10 times per second 24/7, both in standby and during usage. The Eco-wifi router reduces the pulsation frequency of this beacon signal to once per second.
  2. Data packets. Data packets are only transmitted during usage, for example when loading a web page, when an app is requesting information from the internet, or your device is downloading updates etc.

The beacon packets are transmitted continuously, 10x per second, and the data packets only when data is loaded from the Internet. The beacon pulses thus account for a large proportion of electrosmog.

The JRS Eco-wifi router emits 90% fewer beacon pulses per second than regular wifi routers. In this way the Eco-wifi reduces electromagnetic emission, both in standby and also when the wifi is actively used. The emission reduction percentage is 90% when idle (no data transmission) and goes down to 0% when the full wifi bandwidth is used, for example when downloading large files.

Measurements

This is measurable using an electrosmog meter. The reduced pulse frequency of the beacon signal in the Eco-wifi routers has been measured by EMF Consult Norway. The oscilloscope images below show the measured electromagnetic emission versus time, on a 200 milliseconds x-axis scale. The left image shows an ordinary wifi router, and the right image shows the Eco-wifi router:

A demonstration is given in the below video from ElectricSense.com, measured with an Acoustimeter. Turn on sound to hear the difference:

Reducing the strength of the pulses

While the average pulse strength of the Eco-wifi beacon signals is 10 times reduced, because of the reduced pulse frequency as explained above, the peak pulse strength in the default setting is similar as with ordinary routers. This is because transmission power is inextricably linked to the range of the router, a physical fact that, unfortunately, cannot changed.

You can reduce the transmit power by adjusting its setting. The Eco-wifi offers fine adjustment of the range with a 1 milliwatt step size. This is an improvement over the standard Asus firmware. The router is shipped with a standard setting of 30mW (42mW for 5 GHz) which can be lowered to 4mW.

To what extent does an Eco router reduce my exposure to wifi radiation?

Wifi is two-way traffic. Although the Eco router greatly reduces the radiation of your router during stand-by and partly during operation, it does not reduce the radiation of your wireless devices. For each piece of data sent from the wifi router, a confirmation is sent back by your device. Wifi radiation from the devices is very strong and you keep the device very close to your body. Especially in data-intensive applications such as video, the wifi radiation is very high. By working with a wired Internet connection, you can minimize your exposure to electromagnetic radiation.
