    The Pros and Cons of LTE vs. WiMAX vs. HSPA+
    October 2010
    Presented by: Jesus Valencia

2. 2
3. Introduction and Background
Motives behind 4G
Rapid growth of mobile subscribers
Exponential growth ofmobile broadband, web/data and video
More cost-efficient provisioning of new and old services
Delivery services with proper charging
Ubiquitous applications and utilities
Key design services

4. Technical Overview
ITU-R includes LTE, WiMAX and HSPA+ on an equal basis
HSPA+ is the natural evolution of WCDMA and HSDPA- 3GPP
LTE does not need to be backward compatible with HSPA - 3GPP
Mobile WiMax came from the data networking world - IEEE
5. Technical Overview
6. Technical Overview
OFDMA and SC-FDMAfor LTE physical layer
X2 interface for seamless HO
LTE Radio Access Network
7. Technical Overview
HSPA+ Radio Access Network
WiMax network IP-Based architecture
8. Technology recommendation
LTE FDD is the recommended technology
Higher Data rates with lower latency time
Interoperability with existing HSPA, WCDMA and GSM
Better efficient terminal battery life due to SC-FDMA
9. Technology recommendation
LTE business and technical impact
Select frequency band and bandwidth to operate
Plan and perform LTE trial selecting 3-5 RAT vendors
Perform LTE trial selecting 2-3 Evolved Packet Core vendors
Address the backhaul operation and maintenance focusing on high capacity transport rings and dependability
Strongly recommended multi-vendor interfaces
Select low power consuming handhelds and high performance non-handheld User equipments
Technical trial timeline
3-4 weeks trial per vendor
4 weeks post-processing, evaluation and selection of vendors
24 weeks installation and rollout
10. Summary and conclusions

  • LTE is an emerging technology with a new market to exploit

11. Equipment manufactures are open to perform free technical trial without buying the equipment 12. 3GPP momentum developing LTE advanced will open more business opportunities in the futureRisks

  • LTE might become outdated in a couple of years

13. LTE is not considered 4G by ITU-R, LTE advanced will be 4G 14. No interoperability with WiMax 15. Vendors with no experience manufacturing the equipment might create delays on the new technology rollout10
