Technical OverviewITU-R includes LTE, WiMAX and HSPA+ on an equal basis

a. HSPA+ is the natural evolution of WCDMA and HSDPA - 3GPP

b. LTE does not need to be backward compatible with HSPA - 3GPP

c. Mobile WiMax came from the data networking world - IEEE

Technology recommendationLTE FDD is the recommended technology

a. Higher Data rates with lower latency time

b. Interoperability with existing HSPA, WCDMA and GSM

c. Better efficient terminal battery life due to SC-FDMA

Page 9: 4G recommendation

LTE business and technical impact

a. Select frequency band and bandwidth to operate

b. Plan and perform LTE trial selecting 3-5 RAT vendors

c. Perform LTE trial selecting 2-3 Evolved Packet Core vendors

d. Address the backhaul operation and maintenance focusing on high

capacity transport rings and dependability

e. Strongly recommended multi-vendor interfaces

f. Select low power consuming handhelds and high performance non-

handheld User equipments

g. Technical trial timeline

a. 3-4 weeks trial per vendor

b. 4 weeks post-processing, evaluation and selection of vendors

c. 24 weeks installation and rollout9

Technology recommendation

Page 10: 4G recommendation

a. Opportunities

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

• Equipment manufactures are open to perform free technical

trial without buying the equipment

• 3GPP momentum developing LTE advanced will open more

business opportunities in the future

b. Risks

• LTE might become outdated in a couple of years

• LTE is not considered 4G by ITU-R, LTE advanced will be 4G

• No interoperability with WiMax

• Vendors with no experience manufacturing the equipment

might create delays on the new technology rollout
