LTE Wish List
① Scalable system bandwidth from 1.4MHz to 20MHz
(paired or unpaired)
④ Increase cell-edge bitrate (e.g. 2-3x HSPA and EV-DO
revA)
② Significantly increased peak data rate (e.g. 100/50Mbps
for DL/UL)
⑤ Reduce the latency (eg.100ms from idle to active, 10ms
for eRAN RTT)
③ Significantly improved spectrum efficiency (capacity)
~1.6 bits per sec per Hz (e.g. 2-4x HSPA and EV-DO
revA)
⑥ Simplify system and terminal design

Key Takeaway
1. MBB usage explosion – up to 1000x by 2020
2. LTE and LTE-Adv are the technology to support the rise in traffic
3. Re-farmed and new spectrum are required to further address demand
4. Hetnet is a must to get capacity to the 500-1000X level, but greatly add to complexity
and cost of the network
5. More attention needs to be given to solutions that can simplifying network deployment
and reduce cost such as Huawei GigaSite
