Advantages of Using Wireless N over Wireless G Standard

802.11g and 802.11n are two important IEEE wireless standards. G standard operates in 2.4GHz frequency with maximum 54 Mbit/s data transfer speed. 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 11g standard is its capability to work in two different frequencies. It supports both 2.4GHz and 5GHz frequencies. This article explains both WiFi standards and compares the features.

Advantages of 802.11n over 802.11g

802.11n is based on Multiple Input Multiple Output antennas and have relatively higher throughput than 802.11g. 11g is working on 2.4 GHz frequency but 11n can work in 5 GHz band and2.4 GHz. This dual-band working of n helps to reduce interference. It is because most of the interference is due to devices like a cordless phone or microwave oven which work at a 2.4GHz frequency. If you are using these devices at your home, you can simply change the frequency mode in 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 N standard over g is about the data transfer rate. Wireless g standard offers maximum 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 11g standard. Wireless n Access Point can cover almost 70 meters but wireless g has just the half of its range.

Why should we choose Wireless n over Wireless g

11n has many advantages of 11g. Some of them are listed below to help you choose between n and g standards.

  1. The range of Wireless n Network is double the range of  g networks

  2. IEEE802.11n works in 2.4GHz and 5 GHz frequencies where IEEE802.11 g works in 2.4 GHz

  3. The data transfer speed of 11n (max 600 Mbps) is higher than that of 11g (max 54 Mbps)

  4. 11n is compatible with 11a in addition to b, and g

  5. N technology has reduced amount of noise compared to its predecessors

  6. N devices can be connected to g network but the maximum data transfer speed will be 54Mbps.
