Wi-Fi Standards - Wi-Fi 4 vs Wi-Fi 5 vs Wi-Fi 6
Wi-Fi 5, Wi-Fi 6 are the certain names we have come across while choosing Routers for ourselves. have we ever thought of, what actually all these stands for. It is important to have information regarding this to choose the best one for us.
What do Wi-Fi standards mean?
WI-FI standards are a set of services and protocols that dictate how your wi-fi network(and other data transmission networks) acts. The most common set of Wi-Fi standards you will encounter is the IEEE 802.11 wireless LAN(WLAN) and Mesh.
Multiple factors affect the speed and quality of internet connections. Transfer technology, your location, the number of people you share connections with, and the device you use are some determinants.
Evolution of Wi-Fi standards.
Wi-Fi was first released to consumers in 1997, the standards are continually evolving-typically resulting in faster speeds and further coverage. With every new capability comes a name change to set standards apart. The capabilities are added to the original IEEE 802.11, they become known by their amendment. In 2018 Wi-Fi alliance took steps to make the names of the standard easier to identify and understand like Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6, etc. It is now easier to understand the 802.11ax standard as Wi-Fi 6. The alliance re-named the previous standards (802.11n and 802.11ac) to Wi-Fi 4 and 5
Why the evolution of Wi-Fi standards was needed?
802.11b used the same 2.4 GHz frequency and had a theoretical rate of 11 Mbps. The components were inexpensive, but it had the lowest maximum speed 0f all 802.11 standards. Later 802.11n came for a replacement.
What are the different standards of Wi-Fi? Which mode is fastest?
Frequency represents the speed at which data is transmitted and received among devices in a wireless network whereas a Channel width is simply the frequency range for the channel.
Wi-Fi standards are of different types with varying Wi-Fi protocols and data rates.
- 802.11ax : 2.4 or 5 GHz frequency and channel width 20,40,80,160MHz , 143 Mbps
- 802.11ac wave 2: 5GHz and channel width 20,40,80MHz, 200 Mbps
- 802.11ac wave 1: 5 GHz and channel width 20,40,80MHz, 200Mbps
- 802.11n: 2.4 OR 5 GHz and channel width 20,40MHz, 72.2 Mbps
- 802.11g: 2.4 GHz and channel width 20MHz, 54 Mbps
- 802.11a: 5 GHz and channel width 20MHz, 54Mbps
- 802.11b: 2.4 GHz and channel width 20MHz, 11 Mbps
- Legacy 802.11: 2.4 GHz and channel width 20MHz, 1or 2 Mbps
The current wireless networking standard we all use today is referred to as IEEE 802.11ac. The upcoming standard is called IEEE 802.11ax. We can also call it Wi-Fi 6.
802.11g attempts to combine the best of both 802.11a and 802.11b. 802.11g supports bandwidth up to 54mbps and it uses the 2.4 GHz frequency for a greater range. 802. 11g is backward compatible with 802.11b, which means 802. 11g access points will work with 802.11b wireless network adapters and vice versa.
Comparison between the Wi-Fi 4, Wi-Fi 5, Wi-Fi 6 technology on various features and services offered.
The router enabling Wi-Fi 4 can only communicate with a certain number of devices at once, so the more bandwidth-hungry devices you have, the slower your network will work. This Wi-Fi introduced MIMO technology, which allows multiple simultaneous transmissions., but only one device at a time.
The standard IEEE 802.11ac is referred to as WiFi 5. It supports higher throughput due to the addition of higher bandwidth (uptp160 MHz ), multiuser MIMO, higher number of spatial streams (up to 8) and higher number of modulation schemes (256 QAM).
Wi-Fi 6 is capable of the maximum throughput of 9.6 Gbps across multiple channels, compared to 3.5 Gbps on Wi-Fi 5. In, theory the Wi-Fi 6 router could hit speeds over 250% faster than current Wi-Fi 5 devices. These routers are 100% backward compatible with Wi-Fi 5 and older devices. It has a better range and can run both on 5GHz and 2.5 GHz bands. This helps the network feel more navigable and the range feels larger as a consequence of the stability.
Benefits of Wi-Fi 6
- Supports Internet of Things and mobile devices.
- It has a greater channel width with more efficient bandwidth sharing.
- The efficiency is improved with backward compatibility.
The Bottom line
SIF provides excellent bandwidth management with its powerline technology. It is a great choice for homes that are struggling with latency and network blocks. This is made special for those facing network dead areas in their homes. The strong network is the core of super connectivity and flawless speed while transmission of information and even receiving the signals. With SIF, one can make the best choice when it comes to connectivity and smart choice.
