English term or phrase:WiFi “hot-spots"
The radio spectrum is defined as all the waves operating at frequencies between 3 KHz and 300 GHz.
It is divided into “bands”, i.e. ranges of frequencies. Different applications use different bands: terrestrial TV is between 400 and 800 MHz, mobile phones around 900, 1800 and 2000 MHz, cordless phones below 1900 MHz, WiFi “hot-spots” at 2.4 or 5 GHz and satellite communications often at even higher frequencies.
