Evolution of Wireless Technologies

- The predominant use case of 1G was voice calls.
- With the advancement of 2G, there was a shift from analog voice to digital voice paradigm.
- By using digital modulation, 2G would digitize our voice for a more efficient & clear transmission.
- Text messaging was also introduced with 2G communications.
- 3G enabled users to have internet access on their mobile devices.
- 4G provided peak data rates in excess of 1 Gbps, a massive leap from 3G.
Why Do We Need Something Beyond 4G?

5G NR: New Levels of Capability and Efficiency

- Mission critical applications can greatly benefit from such low latency performances.
- 5G will support various types of connected devices which will increase the network density.
5G NR Sevice Classes Overview

Enhanced Mobile Broadband (eMBB)

- Macrocells can cover up to an area of a few square miles in outdoor environments.
- Small cells provide coverage in smaller but dense venues.
- Focused coverage is provided by placing smaller base stations in higher quantities.
Massive Machine-Type Communications (mMTC)

Ultra Reliable Low Latency Communications (URLLC)
