2. 210/1/2016 WirelessMAN-OFDMA Favor Operator and Disfavor User Review on current deployment –TeliaSonera (FDD: 40MHz): Peak rate: 59.1 Mbps in downlink and 18.2Mbps in uplink Average rate: 33.4 Mbps in downlink and 12.7 Mbps in uplink –Chunghwa Telecom (FDD: 20MHz) Experimental peak rate with mobility: 45 Mbps in downlink and 20Mbps in uplink –UQ (TDD: 10MHz) Peak rate: 40Mbps downlink and 10Mbps in uplink Spectrum efficiency –TeliaSonera: 1.48 bits/sec/Hz in downlink and 0.445 bits/sec/Hz in uplink –Chunghwa Telecom: 2.25bits/sec/Hz in downlink and 1bit/sec/Hz in uplink –UQ: 4bits/sec/Hz in downlink and 1bit/sec/Hz in uplink From OPERATOR point of view, WirelessMAN-OFDMA is winner However,……

3. 310/1/2016 User Experience End users have no knowledge to differentiate WirelessMAN-OFDMA and LTE and they only want to have the same user experience under reasonable price. Datacomm works as long as their QoS is good From USER point of view, LTE is winner

4. 410/1/2016 Counter Strategy Wider bandwidth support –Pro: existing in WirelessMAN-OFDMA –Con: not in WiMAX profile and existing product IEEE 802.16m –Pro: ultimate solution –Con: Decrease user experience for WirelessMAN-OFDMA in early stage Market timing Product stability Multi-carrier –Pro: 10MHz WirelessMAN-OFDMA is verified in the field Quick to the market –Con: WirelessMAN-OFDMA does not specify this feature

5. 510/1/2016 Migration to IEEE 802.16m Significant gap between IEEE 802.16m and WirelessMAN- OFDMA Part of IEEE 802.16m features could be transplated to WirelessMAN-OFDMA Forward compatibility could be considered

6. 610/1/2016 Other Features Network deployment support –Frequency reuse 1 –Inter-cell interference control Power saving VoIP efficiency

7. 710/1/2016 Conclusions WirelessMAN-OFDMA is competitive but needs to improve user experience Enhanced WirelessMAN-OFDMA paves a way for migration to IEEE 802.16m Recommended to start a new study group for 16e enhancement features High Priority features 1.Multi-carrier 2.20MHz review and supplement 3.Power saving enhancement 4.ICIC enhancement Low Priority features 1.Co-existence (Implementation Issue) 2.VoIP enhancement 3.Higher layer MIMO and MU-MIMO
