Thank you for your question.
The theoretical values for router emissions are well below the Health Canada guidelines. Typically, the value at 4 m is approximately 70,000 times lower than the exposure limits, and at 1 m, it is approximately 4,000 times lower. The routers are therefore perfectly safe.
Keep in mind that the power density of emissions diminishes rapidly with distance. At 100 m, the emission power is close to forty-three million times lower than the standard. At 500 m, it is virtually impossible to measure a router’s emission levels accurately, because they are more than a billion times lower than the standard in effect.
Last, readers are read automatically over a mesh network, which means that a meter sends a signal for a few milliseconds to the nearest meter and so on to the closest router.
