Road to 5G: Where we are Heading for MBB Evolution

  1. 1. < Road to 5G > where we are heading for MBB Evolution Faisal Mobarak Core Network Planning Grameenphone
  2. 2. The World Economic Forum's Networked Readiness Index (NRI) measures the propensity for countries to exploit the opportunities offered by information and communications technology (ICT)
  3. 3. 30 years of Evolution TD-LTE WCDMA HSDPA/ HSUPA HSPA 2G 3G 4G “Agreed” disruption Smooth evolution “Disruptive” disruption GSM GPRS EDGE E-GPRS2 Single carrier TD-SCDMA TD-SCDMA TDMA PDC CDMA 1X EV-DO rev B UMB WiMAX 16e WiMAX 16d EV-DV LTE-FDD FDD TDD EV-DO rev A EV-DO rev 0 LTE-adv Year in commercial service 2000 2005 20101995 20151990 2020 LTE-adv WiMAX 16m HSPA evol 5G5G 5G CIoT?
  4. 4. 2010 2015 2020 2025 20302005 LTE 5G (<6 GHz) 5G (>20 GHz) WLAN ?Legacy 2/3G Why 4G is not enough ?? • Key 5G use cases are not economically or technically achievable with the evolution of 4G - Low latency (1ms) challenges LTE framework and the hybrid retransmission approach - Connection density (200,000 devices / km²) pressures LTE connection-oriented control plane - More consistent Quality of Experience (QoE) pushes need for a more flexible optimization - Simultaneous support for wider range of use cases drives need for a more adaptable network - High density zones will eventually exceed LTE spectrum bands forces need for new radio access technologies for new spectrum bands above 20 GHz. - Need to evolve the security infrastructure to handle a number of attached devices • 4G LTE - Evolution continues well after 5G launch • 5G - Low band deployed from 2020 first on macro cell then on small cells - High band on small cell follows as 5G capacity needed
  5. 5. What’s driving 5G? BROADBAND Massive traffic capacity Reduce Cost Spectrum efficiency Access new spectrum EXTREME DENSITY Massive user density User content MISSION CRITICAL Very low latency High reliability High availability Security INNOVATIVE SERVICES Flexible bearer design 3rd party policy BATTERY LIFE Signaling reduction Energy optimization NON TRADITIONAL DEVICES Short packet Sporadic access More devices and more device types 5G 5G should focus on solving these issues
