What are the measured levels of EMF emitted by the JRS Eco 100 router compared with those from an ordinary router?

How much less radiation does the JRS Eco 100 router emit compared to a standard router? In this test, we take two commonly used electrosmog meters — a Safe and Sound II RF meter and a Cornet ED98 QPro 5G — to demonstrate the differences.

Measured EMFs from an ordinary WiFi router

An ordinary WiFi router typically comes with the transmission power set to a default value of 100 milliwatts. At a distance of 8 feet, at the factory default settings, we measured a continuous EMF level of 31,300 microwatts per square meter, measured with the Safe and Sound Pro II RF meter. Results vary depending on the brand and type of router, but it’s usually in the range of tens of thousands of microwatts per square meter. In some cases, the transmit power can be adjusted, but often only in very rough increments—for example, no lower than 33%—and with some brands not at all. Furthermore, the number of pulses is of importance: an ordinary WiFi router emits 10 beacon pulses per second, 24 hours a day.

Figure 1. Measured EMFs from an ordinary WiFi router at the factory default settings are 31,300 µW/m², 10 pulses per second. Measured with a Safe and Sound Pro II RF meter at a distance of 8 feet (=2.5 meters). Click image to enlarge.

Range and measured EMFs versus the transmit power setting for the JRS Eco 100 Era router

The JRS Eco 100 Era router emits significantly lower levels of EMF. Its default level is much lower than that of ordinary routers, and it has a very fine-grained transmission power setting that can be adjusted in 1 dB increments. This allows you to set exactly the range you need and no more, with 20 steps from 1 milliwatt to 100 milliwatts. Additionally, the number of pulses per second is reduced by 87% to approximately one per second.

Figure 2. With the output power set to 1 milliwatt, the JRS Eco 100 Era router has the lowest EMF emissions available on the market: 280 µW/m², measured with a Safe and Sound Pro II RF meter at a distance of 8 feet (=2.5 meters). Click image to enlarge.

It’s important to understand that transmission power is inextricably linked to a router’s range — it’s a physical fact of life. We ship the JRS routers with an output power of 20 milliwatts by default (previously 63 milliwatts), which provides an adequate range for a medium-sized home. You can manually adjust the output power to suit your needs, giving you exactly the range you want. When set to 1 milliwatt, the JRS Eco 100 Era router has the lowest EMF emissions on the market. With the Safe and Sound meter, we measure it at only 280 microwatts per square meter (µW/m²) at a distance of 8 feet.

These levels are measured with WiFi active on the JRS Eco 100 router. When no WiFi devices are connected, the JRS router is 100% EMF-free.

The table below shows the exact level of emitted power measured. As different brands of EMF meters respond differently, we have included readings taken with both the Safe and Sound Pro II RF meter and the Cornet ED98 QPro 5G meter for easy comparison. The Safe and Sound meter is more sensitive to WiFi frequencies than the Cornet meter and thus produces higher readings.

JRS Eco 100 Era Power / Range setting * [milliwatt] for 2.4 GHz and 5 GHz (both active)	Range	Measured with WiFi active. (When the JRS router is in sleep mode, RF emission is zero.)
		Measured with Safe and Sound Pro II RF meter at 8 feet distance	Measured with Cornet ED98 QPro 5G meter at 2 feet distance		Measured with Rohde & Schwarz FSH6 spectrum analyzer at 2 feet distance
		Power density [µW/m²] (Lower is less EMF)		Channel power [dBm] (Higher is less EMF, logarithmic)
1 ← Lowest EMF of all	Minimum	280	290	-34	-33.4
10	Medium	1320	1076	-26	-26.7
100	Large	9220	7110	-18	-18.6

* How can I adjust the transmit power of the JRS Eco 100 Era?

In the US, a higher maximum WiFi power is permitted than in Europe, so an ‘extra large’ range is available for 2.4 GHz in the US (up to 800 milliwatts). However, we do not recommend using it because of the high levels of EMF.

Figure 3. EMF emissions of the JRS Eco 100 Era router, measured with a Cornet ED98 QPro 5G meter at a distance of 2 feet (=0.6 meters). To make it easier to compare, the measurement was taken at a shorter distance, as the Cornet is less sensitive to WiFi frequencies.

Figure 4. The measurements taken with the Rohde & Schwarz FSH6 spectrum analyzer confirm the factor between the measurements at different power and range settings. The spectrum analyzer is the most accurately calibrated measurement device. This picture shows a channel power measurement at a power setting of 63 milliwatts at 2 feet distance.
