Difference Between 2G Wi-Fi and 5G Wi-Fi (With Table)

Radio frequencies transmit the internet to different devices. From 2G, we have 5G now. Depends on the coverage and bandwidth, 900 MHz and
5 GHz got differentiated. Radio spaces split among various devices which, might cause overcrowd. It is vital to choose the correct frequency which is suitable for you. It gives a better experience of the internet from internet providers.

2G Wi-Fi vs 5G Wi-Fi

The difference between 2G wi-fi and 5G wi-fi is their coverage and their bandwidth length. The 2G wi-fi covers a larger area but gives less data transfer. The 5G wi-fi covers a smaller space but supplies more data transfer. The 2G can penetrate solid objects easily. The 5G connects fewer devices with its frequency. The speed of the internet you get is the internet service you pay for the service provider.

The 2G radio frequency will cover more space and provide less data transfer. The 2Ghz has a maximum speed of 150 MBs. It has more interference and disturbance. The 2G will cover a larger area, and it is a better option for your home. The 2G is the second generation technology with very low-speed internet. Most of the developed countries shut down the 2G frequency. The speed of 2G can not match with the new evolving technologies.

The 5G radio frequency covers less space but gives more data transfer. It is the fifth generation technology With broadband cellular networks. Most of the internet providers are getting transferred to 5G culture. According to the census, 5G has more than 2 million subscribers at the end of 2025. In 5G, the service area is categorized into cells of hexagon shapes to provide uninterrupted internet to the subscribers.

What is 2G Wi-Fi?

The 2G has commercial launches in 1991 in Finland. The second and a half-generation is the name of the 2G implementation. The main aim of 2G frequency is to provide secure phone calls, short message services, and data services. The GSM and CDMA are the first protocols used in 2G technology. After 2G moved to TDMA(Time Division Multiple Acess) based on GSM. The radio signals in the 2G network are digital.

The 2G Wi-fi is a low-frequency band. It covers maximum space and penetrates heavy walls. It amplified around 410 feet. The data rate gets reduced when more devices connect to the Wi-fi. If the device is longer from the router, then 2G is the better option. The older equipment is better to mingle with 2GHz Wi-fi. A machine like a microwave, Bluetooth devices, baby monitors is joined with 2G to work efficiently.

The 2G has long waves that provide a high range of transmission. For browsing the internet in a high range distance from the router, then 2G is the correct option. The maximum speed of 2G is 600MBs. The antennas, routers of 2G are available at a low cost. The 2G spectrum produces noise around it due to its overcrowded devices. You can connect only the devices with base bandwidth usage to the 2G Wi-fi.

What is 5G Wi-Fi?

The 5G is the fastest network within a short range of area. It is less congested, results in more stability on the internet. The waves are lower in limit. So, they cannot penetrate heavy solid walls. The range extenders and mesh Wi-fi systems will expand the wave’s length, but they are expensive. It affects your money to bring more machines for Wi-fi. The geographical area divided into cells has 38 to 128 antennas. It may increase the performance to 5 times better.

The 5G frequency makes the speed of the internet up to 1300MBs. It has no noise in its frequency spectrum since it has no overcrowded. That gives the higher speeds. The new technology will larger the bandwidth and provide speed up to 10 gigabits per second. The 4G accessed mobile phones are not able to access the 5G frequency. The additional frequency will help to increase the speed of the internet. The 5G has three types of bands with a distinct range of waves.

The enhanced mobile communication and ultra-reliable low latency communication will progress the 4G LTE into 5G technology. The air latency of 5G marks as 8-12 milliseconds in 2019. To make the bit error low, 5G uses adaptive modulation and coding scheme technology. It makes the speed at zero error rate. The edge computing in 5G will reduce the data latency and traffic congestion.

Main Differences Between 2G Wi-Fi and 5G Wi-Fi

  1. The 2G Wi-fi covers more space, and the 5G Wi-fi covers less area.
  2. The 2G Wi-fi has Less speed rate, and the 5G Wi-fi has a High-speed rate.
  3. The 2G Wi-fi has More interference, and the 5G Wi-fi has Less interference.
  4. The 2G has more disturbance, and 5G has limited agitation.
  5. In 2G, Overcrowded happens often, and 5G is not much overcrowded.
  6. The 2G costs cheap compare to the 5G, and 5G is expensive.


Using the dual-band routers will make you experience both frequencies. Since 5G provides much speed on the internet. It won’t penetrate solid walls and reach mare space like 2G. You can separate the band to get high-speed internet in your home. You need for wide-area 2G is better. If you need high speed, then 5G seems better. Choosing the correct Wi-fi for your home depends on the area you have and the speed you need will make to reduce the cost and give better experience.
