Have you ever purchased a new WiFi router and you noticed that the router has both 2.4 GHz and 5 GHz frequency bands or maybe your existing router has both of them? Have you ever wondered why some routers have these dual bands? So that\u2019s what we\u2019re going to talk about in this video.<\/p>\n<p>Now a frequency band is how wireless data is transmitted between devices. These bands are radio waves that carry the data and these bands are either 2.4 GHz or 5 GHz. Now a lot of WiFi routers will only transmit one of these bands, which would be the 2.4 band and that\u2019s because it\u2019s the most common frequency and these are called single-band routers. But a lot of newer WiFi routers will transmit both the 2.4 and 5 GHz bands and these are called dual-band WiFi <a href=\"https:\/\/www.fastmetrics.com\/blog\/tech\/managed-routers\/\">routers<\/a>.<\/p>\n<figure id=\"attachment_1570\" aria-describedby=\"caption-attachment-1570\" style=\"width: 500px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1570\" src=\"https:\/\/www.fastmetrics.com\/wp-content\/uploads\/sites\/5\/2019\/10\/netgear-nighthawk-dual-band-router-5ghz-2-4ghz-1024x757.jpg\" alt=\"black netgear nighthawk multi antenna dual-band wifi router 2.4 vs 5ghz frequency options\" width=\"500\" height=\"370\" srcset=\"https:\/\/www.fastmetrics.com\/blog\/wp-content\/uploads\/sites\/5\/2019\/10\/netgear-nighthawk-dual-band-router-5ghz-2-4ghz-1024x757.jpg 1024w, https:\/\/www.fastmetrics.com\/blog\/wp-content\/uploads\/sites\/5\/2019\/10\/netgear-nighthawk-dual-band-router-5ghz-2-4ghz-300x222.jpg 300w, https:\/\/www.fastmetrics.com\/blog\/wp-content\/uploads\/sites\/5\/2019\/10\/netgear-nighthawk-dual-band-router-5ghz-2-4ghz-768x568.jpg 768w, https:\/\/www.fastmetrics.com\/blog\/wp-content\/uploads\/sites\/5\/2019\/10\/netgear-nighthawk-dual-band-router-5ghz-2-4ghz-624x461.jpg 624w, https:\/\/www.fastmetrics.com\/blog\/wp-content\/uploads\/sites\/5\/2019\/10\/netgear-nighthawk-dual-band-router-5ghz-2-4ghz.jpg 1280w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><figcaption id=\"caption-attachment-1570\" class=\"wp-caption-text\">NETGEAR Nighthawk Dual Band WiFi Router<\/figcaption><\/figure>\n<p>Now the 2.4 band works pretty well. It\u2019s the standard band. But the problem is that it\u2019s not just a standard band that\u2019s used in WiFi routers. It\u2019s also the standard band that\u2019s used in a lot of other devices. Things like microwave ovens, <a href=\"https:\/\/www.fastmetrics.com\/dect-phones\">cordless phones<\/a>, <a href=\"https:\/\/www.fastmetrics.com\/support\/bluetooth-headset-compatible-phones\/\">Bluetooth<\/a> devices and wireless cameras all use the 2.4 GHz band and this became a problem.<\/p>\n<h4 style=\"text-align: center;\">What Is The Purpose Of The 5GHz Frequency Band?<\/h4>\n<p>Because of the fact that so many other devices use the 2.4 band, the signal became overcrowded and was causing a lot of interference with WiFi signals and when this happens, it slows down the <a href=\"https:\/\/www.fastmetrics.com\/managed-business-wifi-service.php\">WiFi network speed<\/a> and sometimes could cause you to lose connection to the WiFi router.<\/p>\n<p>That is why the 5 GHz band was added. The 5 GHz band is a newer band and so it\u2019s not as commonly used as the 2.4. It\u2019s used by fewer devices and because it\u2019s used by fewer devices, the 5 GHz is not as crowded. So there is no interference or minimal interference. Using the 5 GHz would relieve the problem related to slow network speeds and connection drops that will be caused by interference from other devices. Another reason why the 2.4 is more vulnerable to interference is because of the difference in wireless channels. Now if you\u2019re not familiar with what a wireless channel is, a wireless channel is just a way to fine-tune and alter a frequency. Sometimes you might need to <a href=\"https:\/\/www.fastmetrics.com\/blog\/wifi\/factors-affecting-wifi-performance\/\">change to a different channel if you are experiencing interference<\/a> from different wireless devices and changing to a different channel will give you that ability.<\/p>\n<p>The 2.4 GHz band has 11 channels to choose from. But of these 11 channels, only 3 are non-overlapping. So basically you have 3 solid channels to choose from. But the 5 GHz has more channels. It has 25 non-overlapping channels. Some other differences between the 2.4 and 5 GHz band is the speed and the range that they cover. The 2.4 GHz band transmits data at a slower speed than the 5 GHz. But it does have a longer range than the 5 GHz. The 5 GHz band <a href=\"https:\/\/www.fastmetrics.com\/blog\/internet-services\/speedtest-results\/\">transmits data at a faster speed<\/a> than a 2.4. But it has a shorter range. The 5 GHz has a shorter range because it has a higher frequency and higher frequencies have a harder time penetrating solid objects such as floors and walls in a building.<\/p>\n<p>As you can see on this illustration, this dual band WiFi router is broadcasting a 2.4 GHz band which is the green color and it\u2019s also broadcasting a 5 GHz band, which is the red color. So as you can see, the 2.4 band has a longer range and the signal can cover most of this building and it can also penetrate the second floor and the walls. But the 5 GHz band has a shorter range. The signal doesn\u2019t penetrate the second floor or the walls, which limits its range inside a building.<\/p>\n<h4 style=\"text-align: center;\">So The Question Is &#8211; Which Band Do You Want To Actually Use?<\/h4>\n<p>And that really depends on your situation. They both have their advantages and disadvantages. The advantage of a 2.4 GHz is that it has a farther range and it can penetrate solid objects better. However the disadvantage that it has, is that it\u2019s more vulnerable to interference. That&#8217;s because so many other devices use the same band and it\u2019s also slower than the 5 GHz.<\/p>\n<h4 style=\"text-align: center;\">What Are The Advantages \/ Disadvantages Of Using 5Ghz?<\/h4>\n<p>The advantage of 5 GHz is that it has a higher transfer speed and it\u2019s less vulnerable to interference. But at the same time, it does have a shorter range. And it has a harder time penetrating through solid objects. If you\u2019re interested in getting a dual band WiFi router, I will put a link in the description of this video below. This is of a dual band WiFi router that I personally recommend. Thank you for watching.<\/p>\n<p>Update: There&#8217;s a new kid on the block and it offers better coverage for multiple devices on a single WiFi network and much faster speeds.
