These mixtures enable the transmission of parallel noninterfering data channels. Higher frequencies allow larger bandwidth and more data to travel through a channel , if the architecture of the channel is such that the data is not garbled by interference.
Read moreWhy are higher frequencies better?
The main advantage of higher frequencies is that they require shorter antennas for decent reception quality , and that’s important for mobile devices. But high frequencies are more sensitive to reflection, so they will have a harder time passing through walls and obstacles in general.
Read moreWhat is the relationship between frequency and bandwidth?
The basic difference between the two is that frequency is defined as the rate of radio signal to send and receive communication signals, whereas bandwidth is defined as the difference between the highest and the lowest frequencies of a signal generated .
