Wi-Fi 2.4GHz and 5GHz are two frequency bands used by Wi-Fi networks to transmit signal. The best secure wireless routers installed have these two bands for signal transmission. Such routers are called dual-band wireless routers. However, these two bands are difference from each other and have their own set of benefits and limitations. Let’s delve deeper into it.
Wi-Fi 2.4GHz and 5GHz – An Introduction
Wi-Fi signals operate on different bands of which2.4GHz and 5GHz are two most common frequencies. A 5GHz network carries more data than 2.4 GHz and is faster. It supports higher data rates in 802.11n, 802.11ac and 802.11ad. Streaming videos or playing online HD games is a better experience on 5GHz band.
Wi-Fi 2.4GHz has larger coverage range than 5GHz. The reason being 5GHz isn’t able to penetrate into solid objects the way 2.4GHz does.
2.4GHz is Everywhere
Electronic devices such as microwaves, cordless phones and even automatic garage door operators use 2.4 GHz frequency. The frequency is common in consumer products that’s why a home wifi network with 2.5GHz band will have more interference and congestion in comparison to 5GHz. As a result, wifi speed will be slow.
The Cost
5GHz is often seen as a newer and more expensive technology than 2.4GHz. The truth, however, is that both the technologies have been here for long. It’s just that the most secure router with 5GHz marked their entry in the market after 2.4GHz routers.
The routers that support only 2.4 GHz frequency are less costly than the ones supporting both 2.4GHz and 5GHz bands.
What’s Better – 2.4GHz or 5GHz?
Both the frequencies are different from each other and have their own set of limitations and benefits. You can get optimal performance from each frequency by providing them ideal environment. For instance, if there are no concrete walls and less consumer products, 5GHz will deliver an exceptional performance. The frequency can, however, disappoint you in the opposite scenario. It makes more sense to buy a wifi router that supports both the bands, so that you can change the frequency accordingly and work optimally.
