From WiMAX to LTE 3 Steps Plan

Linkem - The 5th TD-LTE Technology and Spectrum Workshop 2015

Dual Mode WiMAX +Cat.4 LTE

WiMAX (2013) WiMAX+LTE A (Now) 2x20Mhz LTE A (2016)

Dual Mode WiMAX +Cat.4 LTE Dual Mode

WiMAX +Cat.4 LTE

WiMAX WiMAX

Cat.6 LTE (4Q15)

Eventually up to 30M/3M Unlimited Traffic

Target> 2bit/Hz

Nx20Mhz Channels, Frequency Reuse 1

Deterministic Capacity Planning in 3,5Ghz

• WiMAX (In service From 2008)

o 10Mhz Channel Bandwidth o Frame 32:15 o Reuse from 4 to 8 o # users load balancing o Result: 1,7 bit/Hz

• LTE B42 (in service from Dec.14)

o 20Mhz 10Mhz Channel Bandwidth

o Frame 2 Subframe 5 o Reuse 1 o Current result 1,2 bit/Hz o Planned result: 1,8 bit/H

• Subframe 7: +20% • 50% Cat6, 2x20 CA: +30%

o Target >2 bit/Hz • More Fiber (less latency) • DL CoMP • TM7/TM8
