Who still does not know what MIT is should be aware and never forget. MIT (Massachusetts Institute of Technology) is a North American University responsible for many technological innovations in recent years.
This time they are focusing on a topic that has taken my sleep away for a long time: the battery life when we access the internet.
In fact, the research did not come from MIT, but from a company founded by MIT professors, it is called ETA Devices. The system under study could halve the power consumption of the base stations (talking about Mobile Cellular) and consequently, we also talk about smartphones.
What is the secret of this technology?
For the signals to be received there in the Unitel, Movicel… (insert another company here), it needs to be amplified. Our mobile phones have these energy amplifying devices, which are responsible for this. At the same time, these devices convert electricity into radio signals. This amplifier works in high power mode for sending data and also in low power for standby mode. But as the abrupt switching between energy levels can distort the signal, so standby is maintained so that it consumes much more energy than it needs.
If the amplifiers consume very little charge, then the battery life will be longer. This is accomplished by having the amplifier choose the proper voltage at a frequency that can reach more than 20 million times per second.
