  1. 5G Cellular Harshil Shah Rich Valkanet Abhinav Agarwal

  2. Introduction to Mobile Wireless Systems • Global mobile traffic will increase 1000x from 2010 to 2020. • Surge in mobile traffic is primarily driven by data‐hungry mobile devices. • Other important factor is the increasing demand for multi-media applications such as Ultra‐High Definition (UHD) and 3D video/augmented reality. • Future connected society, everyone and everything will be inter‐connected – Internet of Everything (IoE).

  3. Historical Trend of Wireless Communications • 1G - All the wireless communications were voice‐centric. An analogue system with FM radios was chosen named AMPS (Advanced Mobile Phone Service). • 2G - All the wireless communications were voice‐centric. European GSM was digital systems using TDMA multiplexing. Moving from 1G to 2G means migrating from the analogue system to the digital system. • 3G - The wireless communications platform has voice and data capability. 3G exploits WCDMA (Wideband CDMA) technology using 5 MHz bandwidth operating in frequency division duplex FDD and TDD modes. Migrating from 2G to 3G systems we have evolved from voice‐centric systems to data‐centric systems.

  4. Historical Trend of Wireless Communications • 4G - 4G is a high‐speed data rate plus voice system. WiMAX and LTE are 4G technologies with bandwidth of 20 MHz. Migrating from 3G to 4G means a shift from low data rates for Internet to high‐speed data rates for mobile video. • 5G - 5G will be a system of super high‐capacity and ultra‐high‐speed data. 5G envisioned to be a technology ecosystem of wireless networks working in synergy to provide a seamless communication. Moving from 4G to 5G means a shift in design paradigm from a single‐discipline system to a multi‐discipline system.

  5. 10 Pillars of 5G • Evolution of Existing RATs • Small-Cell Deployment • Self-Organising Network • Machine Type Communication • Developing mm Wave RATs • Redesigning Backhaul Links • Energy Efficiency • Allocation of New Spectrum • Spectrum Sharing • RAN Virtualisation

  6. Technique to Achieve 5G • Massive MIMO/Beamforming • Massive MIMO can have dozens of antennas on a single array. • 4G BS can support eight transmitters and four receivers whereas 5G BS can support hundreds. • More antennas, more interference so comes Beamforming. • Beamforming is a traffic-signaling system for cellular base stations that identifies the most efficient data-delivery route to a particular user, and it reduces interference.

  7. Technical aspects of 5G Network Slices QoS Latency

  8. Network Slices • What is slicing? • Divides the production network into logical slices • Each slice controls it’s own packet forwarding • Existing production servers run in their own slice • Action in one slice does not affect the other • Each slice can mirror a production network • Data plane is unmodified (no performance penalty)

  9. QoS - Quality of Service • What is QoS and why do you need it? • Traffic shaping and prioritizing traffic • Who’s first in line • Voice Services • Data Services • QoS in 5G ? • QoS will be monitors by controlled by SDN/NFV • Standards are becoming a sticking point since technology is moving quickly and evolving so fast and operators want this on the network yesterday.

  10. Latency • Everybody loves fast internet • Nobody like Latency • 5G claims • To support vehicles, planes traveling at 300 – 500 Km/h • 5ms end to end latency • 1ms over the air latency

  11. What Qualcomm calls 5G…so should we, perhaps..

  12. All of them working in tandem…

  13. Ok, let’s retreat and rewind..

  14. The verdict and the rationale..

  15. Windowed OFDM and its wonders

  16. Another 4 letter acronym..RSMA

  17. Getting into the nitty-gritties

  18. Yes, now what is ‘Scalable’, finally?

  19. Oh so that’s how it works..

  20. mmWave has been around for some time, then ?

  21. Why non-orthogonality, of all things?

  22. Oh..not just devices in the same spectrum, you mean?

  23. Mission-critical: Mission Possible

  24. You: No free lunch. 5G: Oh really?

  25. Not all that secure though.

  26. Conclusion 5G already available in some test locations around the United States. Although both Verizon and AT&T, the nation’s two biggest internet service providers, are already testing 5G, don’t expect to see it anytime soon. Most experts predict that 5G won’t be widely available until 2020.
