PORTABLE ROUTER WITH VARIABLE WiFi TRANSMISSION POWER, AND METHOD OF REDUCING POWER CONSUMPTION THEREOF

摘要

There are provided a portable router with variable Wi-Fi transmission power and a method of reducing power consumption thereof. The portable router includes: a cellular modulation and demodulation unit converting cellular signals into cellular data packet signals; a gateway unit converting the cellular data packet signals into Wi-Fi data packet signals; a Wi-Fi modulation and demodulation unit converting the Wi-Fi data packet signals into Wi-Fi signals based on preset communication protocols; a power amplification unit amplifying transmission power of the Wi-Fi signals; and a transmission power control unit controlling a gain of the power amplification unit, depending on cellular throughput based on the cellular signals and Wi-Fi throughput based on the Wi-Fi signals.
