2. 26/10/2016 Market’s View FACTS: –The SUCCESS of IEEE 802.16m relies on the success of WirelessMAN-OFDMA –The SUCCESS of WirelessMAN-OFDMA relies on more competitive WirelessMAN-OFDMA product LTE in the market: –Chunghwa Telecom (Taiwan): FDD with10+10MHz Downlink: 60Mbps @ 0km/hr and 10-40Mbps @ 80km/hr Uplink: 20Mbps without mobility @10MHz –TeliaSonera (Stockholm): FDD with 20+20MHz Average: DL: 33.4 Mbps and UL: 12.7 Mbps –……..

3. 36/10/2016 Lesson from these FACTs WiMAX Situation –10MHz product only –HARQ can only support category 4 Maximum throughput can not exceed 20Mbps Multi-carrier can be considered for 16e as well User will have different view of WiMAX due to multi-carrier

4. 46/10/2016 Market Timing Mature product of IEEE 802.16m is hard to be delivered by 2013 –Our experience told us Corrigendum requires some time –Field trial need operator to invest money –However, operator do not consider IEEE 802.16m if they can not return their investment from 16e network –Therefore, industrial investment will be postponed Conclusion: –Three to five years gap between 16e and 16m –16e enhancement can be filled in the gap and enhance the user experience of WiMAX

5. 56/10/2016 Benefits to 16e and 16m Eco-system 16e Chip vendor –New product feature means higher profit chip –Higher profit invites more vendor join 16e supply chain –16e can have more players 16e Base station vendor –Another business opportunity for base station upgradation –New product for high end market such as US, Japan and Taiwan

6. 66/10/2016 Another Issues Power consumption MIMO ICIC

7. 76/10/2016 Possible Features 1.Multi-carrier 2.Green RAN 3.Co-existence
