The 2.4 GHz band provides more coverage but slower speeds. The difference between the two bands is their range, speed, and bandwidth. Most WiFi devices are dual-band, meaning that they can use both frequency bands. There are two GHz frequency bands that routers and wireless devices use to communicate with each other – 2.4 GHz and 5 GHz. 802.11ac Key FeaturesĨ02.11ac built on the features offered by 802.11n to improve throughput, bandwidth, and speed. While it’s true that WiFi 5 is 3x faster than WiFi 4, the speeds are much lower than the theoretical ones. In contrast, the maximum speed recorded for 802.11n was 240 Mbps (0.24 Gbps). Obstacles like building material, walls, doors, floors, and furniture can interfere with the signal strength, resulting in the speed slowing down.įorbes states that the fastest real-world 802.11ac speeds recorded are around 720 Mbps (0.72 Gbps). In the real-world, data rates are susceptible to change due to the environment. This meant WiFi 5 could be up to 3x faster than the earlier WiFi generation under best conditions. In contrast, 802.11n had a theoretical speed of 450 Mbps (0.45 Gbps). It was the first WiFi standard developed that could theoretically achieve gigabit speeds opposed to megabit speeds. 802.11ac has a theoretical maximum speed of 1,300 Mbps (1.3 Gbps) - 2,300 Mbps (2.3 Gbps), but this will depend on real world conditions. They are based on the best conditions - potential interference is not factored in. The difference between these product waves will be discussed later in this article. The first wave was introduced in 2013 and the second in 2015. Two waves of products were launched using the 802.11ac standard. The updated standard was published in December 2013. The improvements would result in a better WLAN experience - faster speeds, more bandwidth, and less latency. To improve the 802.11n standard, the Institute of Electrical and Electronic Engineering developed the IEEE 802.11ac standard from 2008 to 2013. This resulted in speed slowdowns and increased latency. The 4th WiFi generation (IEEE 802.11n) saw a big increase in the number of users and devices using wireless internet. New wireless standards are developed to fill gaps in the existing standards and to account for new technology. The purpose of WiFi standards ( IEEE 802.11) is to improve the wireless local area network (WLAN or Wireless LAN) user experience. WiFi 5 was designed to deliver improved speeds, WiFi performance, and better range to keep up with the growing number of users, devices, and data use.
Wifi bandwidth upgrade#
It’s an upgrade from IEEE 802.11n, or WiFi 4. The 802.11ac standard, also known as WiFi 5 and Gigabit WiFi, is the 5th generation of WiFi.
