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
7
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
