5G Signals and Wireless Communications

Dear colleagues,

Communication technologies and particularly Wireless systems have evolved increasingly over the past decades and continue to do so. It all started from the very first generations (1G and 2G), when users were only able to make voice calls, evolving to have the ability to send and receive text messages, and the third generation (3G) took it to the next level by introducing data transmission and internet browsing to the wireless world, and then the fourth generation (4G) made everything faster and more convenient. The current trend in wireless communications is known as the fifth generation (5G).

5G wireless communication systems provide faster data speeds and better connectivity, which supports massive growth in the Internet of Things (IoT) and enables new possibilities for smarter devices like smart healthcare and self-driving vehicles.

Existing networks in terms of functionality, network features, security, elasticity, management, and physical layer models and components face challenges to meet such a diverse demand.

In this issue, we look at emerging technologies related to enabling wireless communication systems for 5G technologies and beyond.
