What is 5G?

5G is “Fifth Generation” wireless technology.

5G technology provides high bandwidth, so faster and capable of handling a very large number of smart devices, including IOT (Internet of things). IOT is the network of physical devices embedded with electronics, software, sensors, actuators, and connectivity, which enables these things to connect and exchange data.

This 5G technology targets on (Voice over IP) VOIP-enabled devices that user will
experience a high level of call volume and data transmission.

Wireless Technologies and History

1. First Generation (1G):

• It uses analog radio signal.
• Frequency: 150 MHz
• Bandwidth: 2kbps
• Multiplexing: Frequency division multiple access (FDMA)
• Switching: Circuit
• Core Network: Public switched telephone network (PSTN)

2. Second Generation (2G):

• It uses digital signals for voice transmission.
• Bandwidth: 64 kbps
• Multiplexing: Time-division multiple access (TDMA)
• Switching: Circuit
• Core Network: Public switched telephone network (PSTN)

3. Third Generation (3G):

• It uses Wide Brand Wireless Network.
• Bandwidth: 2Mbps
• Multiplexing: Code-Division Multiple Access (CDMA)
• Switching: Packet
• Core Network: Packet network

4. Fourth Generation (4G):

• It uses “WiMAX technology” or “Long Term Evolution” (LTE).
• Bandwidth: 1Gbps
• Multiplexing: Code-Division Multiple Access (CDMA)
• Switching: All packet
• Core Network: Internet

5. Fifth Generation (5G):

• It uses IP based model.
• Bandwidth: More than 1Gbps
• Frequency: 600 MHz to 6 GHz
• Multiplexing: Code-Division Multiple Access (CDMA)
• Switching: All packet
• Core Network: Internet

Advantages of 5G Technology

• High bandwidth and high broadcasting capacity with low cost per bit
• Faster response time
• About 90% reduction in network energy usage
• Battery life will be much longer
• Incredible transmission speed
• It has high error tolerance, so can provide high-quality services
• High connectivity
• It offers global access and service portability
• Uploading and downloading speed is very high
• More clarity in audio and video
• 5G will allow utilization of any spectrum and any access technology for the best delivery of services

Security Concerns For 5G Technology

• Mobile malware attacks like virus, Trojan, worm because of the third-party untrusted software download.
• Malware can help attackers to exploit the stored personal data on the device.
• A mobile botnet can perform automated malware attacks and denial-of-service (DOS) attack.
• Smart device’s location tracking that can affect user’s privacy.

Conclusion

Bandwidth and data transfer rate for 5G technology is high. Now maximum people are using 4G but in future, there will be a big demand for 5G wireless technology. Countries are investing a huge amount of money on this project as it will be playing an important role for growth in technology as well as the economy.
