The term "5 GHz" refers to a frequency band used in wireless communication, particularly in Wi-Fi networks. It operates at a higher frequency than the more common 2.4 GHz band, allowing for faster data transmission rates. This makes 5 GHz ideal for activities that require high bandwidth, such as streaming videos or online gaming. However, the 5 GHz band has a shorter range compared to 2.4 GHz. It is more susceptible to obstacles like walls and furniture, which can weaken the signal. As a result, while 5 GHz offers speed advantages, its coverage may be limited in larger spaces or areas with many obstructions.
