• Commercial process of TD-LTE
– TD-LTE already came into commercial stage worldwide

• Wireless Network development & challenges to operators
• Nanocell introduce, concept and evolution

• Progress of TD-LTE Nanocell
• Industrial expectations
• WBA Congress in Beijing

TD-LTE already came into commercial stage worldwide

• 18 TD-LTE commercial services launched globally by the first half year of
2013, including Mobily、STC、Softbank、SKY TV、On、Hi3G Sweden、
Hi3G Demark、UK Broadband、Bharti Airtel、Australia NBN、Aero2
Poland、Omantel、MTS Russia、Megafon、CMCC HK、Dialog Axiata、
Telkom Mobile / 8ta
• 50,000 TD-LTE base stations deployed globally by the end of 2012
• 200 models of TD-LTE terminal launched globally by the first half year of
2013， most of them are data cards and LTE CPE/Mobile Hotspot, 29
smart phones
• 3.6 million TD-LTE customers developed by the first half year of 2013

First half of 2013, GTI has
developed
56 operator members
54 vendor partners

Outline

– Why introduce Nanocell?
– What is Nanocell?
– How will Nanocell develop?


Small cell and WLAN are considered as effective, low cost
and broadband wireless coverage solutions
Cellular network architecture will transform
from macro cell to small cell

WLAN is a low-cost wireless broadband
access technology

Ways to improve wireless network capacity

New spectrum Spectrum efficiency Smaller cells
X times
Y times
Z times

Development of WLAN is also speed up
802.11ac
300 Mbps

802.11n

Capacity growth: X*Y*Z
Which one can be enlarged easier? X? Y? Z?
Rely only on macro cell to meet future network
capacity demand is impossible.

Mobile network architecture will transform
from macro cell to high-capacity, low-cost and
green small cells.

100 Mbps

802.11g
20 Mbps

higher access rate

China Mobile is making big effort on WLAN network
construction.

•Already deployed 4 million APs by April 2013
•Will achieve 6 million APs in the next 2 years

It is natural to integrated small cells with WLAN to further increase
network capacity and reduce network CPAEX/OPEX

Nanocell concept and Features
•

Nanocell：a type of base station integrated with small cell (including 2G / 3G /
LTE, single or multiple modes) and WLAN AP.

1.

WLAN and cellular network
2.

Support co-coverage and interference
collaboration between cellular system and
WLAN：reduced co-exist interference and
guaranteed coverage & capacity of the two
systems

3.

Support flexible and low cost backhaul
link transmission：Nanocell can support
wired and wireless backhaul network

4.

Low CAPEX & OPEX： SoC based
architecture, low cost, low power
consumption, small size
