Wireless Internet access can be simply understood as wireless Internet access. Almost all smartphones, tablets and laptops support Wi-Fi access, which is the most widely used wireless network transmission technology today.

The harm of microwave to human body mainly refers to the influence of low-intensity chronic radiation, and high-intensity acute effect can also cause harm to human body, but it rarely happens. Its performance is as follows:
1, the effect on nervous system
The nervous system is highly sensitive to microwaves. Repeated exposure to low-intensity electromagnetic radiation will change the function of the central nervous system, resulting in neurasthenia and other symptoms, mainly manifested as dizziness, lethargy, fatigue, decreased memory and increased slow waves in EEG. Besides neurasthenia, the biggest feature of electromagnetic radiation is that it makes the autonomic nerve function disorder.
2. Effects on cardiovascular system
Under the action of microwave, hemodynamic disorder, vascular permeability change and ECG change often occur. The blood pressure of people exposed to microwave for a long time decreased, but some of them increased. Electrocardiogram analysis shows that besides bradycardia, there are tachycardia, sinus arrhythmia, atrial or ventricular premature beats, and changes of heart and skin ischemia under ST segment depression and T wave depression. While others may develop autonomic neurovascular dysfunction.
3. Effects on eyes
The human eye's crystal is vulnerable to electromagnetic radiation, and its internal blood flow is small, so the temperature is extremely high under electromagnetic radiation. Experimental research shows that microwave radiation can cause cataract, and its threshold is about1100mw/cm2 for single irradiation and 80mW/cm2 or lower for repeated irradiation. High-intensity electromagnetic radiation can also damage cornea, iris and anterior chamber, resulting in vision loss or complete loss. When the intensity is lower than the above threshold, although it will not cause cataract, the electromagnetic radiation of 10~80mW/cm2 can still make the lens turbid, and may shorten the colored visual field and prolong the dark adaptation time, resulting in some visual obstacles.
4. Effects on reproductive system
According to the hygienic investigation, after long-term microwave operation, men may have impotence and sexual dysfunction, and women may have menstrual disorders. High-intensity microwave radiation may also cause miscarriage in pregnant women. In addition, microwave radiation may also lead to glucose metabolism disorder and female secretion function decline. In a word, microwave radiation has many effects on human health. Studying its influence on human health can provide scientific basis for preventing and controlling microwave hazards and create necessary safety environment for the wide application of high-power microwave technology.
