CoreNetworkZ Tech Solutions has been in the wireless configuration business since 2009. We configured corporate and SOHO networks with the latest wireless technologies.
I have expertise in configuring wireless devices supporting standards from IEEE 802.11a to IEEE 802.11ax.
Today, I am comparing two older WiFi standards, IEEE 802.11g and IEEE 802.11n. This article explains both WiFi standards and compares the features.
IEEE 802.11g Vs IEEE 802.11n
802.11g and 802.11n are two IEEE wireless standards. G standard operates in 2.4GHz frequency with a maximum 54 Mbit/s data transfer speed. The wireless N standard is an improvement over its predecessor with the help of additional antennas.
This additional antenna improves the data transfer rate up to 600 Mbit/s. Another advantage of the 802.11n standard over the 11g standard is its capability to work in two different frequencies. It supports both 2.4GHz and 5GHz frequencies.
Advantages of 802.11n over 802.11g
Let us check the practical advantages that the Wireless N standard offers over the Wireless G standard.
802.11n is based on the Multiple Input Multiple Output antennas and has relatively higher throughput than 802.11g. 11g works on 2.4 GHz frequency but 11n can work in 5 GHz band and 2.4 GHz.
This dual-band working of n helps to reduce interference. Most of the interference is due to devices like a cordless phone or microwave oven which work at a 2.4GHz frequency.
If you have these devices at home, you can change the frequency mode in the n router to 5GHz. So, we can avoid most of the interference chance. 11g has backward compatibility with 802.11b but N standard offers Backward compatibility with 802.11a, 11b, and 802.11g.
Another major advantage of the N standard over g is the data transfer rate. Wireless g standard offers a maximum of 54 Mbit/s but the maximum data transfer rate of wireless n standard is 600 Mbit/s.
It is possible due to the usage of Multiple Input Multiple Output(MIMO) antennas and it also helps to reduce the noise. Now let us consider the WiFi range. 11n standard offers a higher range than the 11g standard. Wireless n Access Point can cover almost 70 meters but Wireless G has just half its range.
Why should we choose Wireless N over Wireless G?
After reading this article, I am confident that you understand the advantages of Wireless N standard over Wireless G. I know that now the market has better wireless standards (802.11ax and 802.11ac), but they are costly.
Now I explain the reason for I chose wireless N over wireless G for SOHO networks. I listed a few reasons below, and it will help you choose between n and g standards.
The range of Wireless n Network is double that of the g networks.
IEEE802.11n works in 2.4GHz and 5 GHz frequencies whereas IEEE802.11 g works in 2.4 GHz.
The data transfer speed of 11n (max 600 Mbps) is higher than that of 11g (max 54 Mbps).
802.11n is compatible with 11a in addition to b, and g.
Wireless N technology has reduced noise compared to its predecessors.
Wireless N devices can connect to a wireless g network but the maximum data transfer speed of that connection is 54Mbps.
Hi,
ReplyDeleteThe Internet connection I am momentarily using of is DSL 6Mbps, which is way below than what a Wireless G 54Mbps router can handle.
So why should I get a Wireless N standard router? It won't make the DSL 6Mbps connection faster, now would it?
I can understand why I should get a Wireless N router if the internet connection had been ADSL 50Mbps or higher.
Hi Dr.X
ReplyDeleteA faster WiFi router can improve the speed of file transfer between computers connected to it. If you are using router to share Internet connection only, 802.11G network is fine but if you use LAN games or other network applications, faster network can improve the performance.
It was a great read Alex. I know wireless N is better that wireless G. But, I still miss my Linksys WRT54G router. That device was an excellent piece.
