The data is clear. My phone’s battery charge life looks better with 5G turned off.
To determine blood oxygen (arterial blood oxygen saturation (SpO2)) and pulse rate, many biosensors use the reflectance of red and infrared (and sometimes green) light. Based on photoplethysmography (PPG), an optical technique that measures blood volume variations, dual-wavelength PPG pulse oximeters noninvasively measure/calculate the arterial oxygen saturation (SpO2). An oximeter transmits radiation at a known […]
Have you ever had to transition someone from a flip phone to a smartphone? Things you instinctively know how to do become obstacles. Fortunately, you can talk to a smartphone rather than just talking through it. With 3G heading into sunset, some cellphone users will need to upgrade to LTE or 5G before their phones…
