Shift to capacity and impact of China will bring TDD to center stage

The importance of TDD

October 2013



• Harnessing underused TDD spectrum addresses capacity challenge• Some carriers will use TD-LTE for separate small cell layer• TDD especially prominent in new architectures• Better convergence with FD-LTE increases total spectrum pool for operators• Dual-mode carriers include China Mobile HK, 3 Group• First dual-mode devices certified 2013

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.

Ways to improve wireless network capacity

Capacity growth: X*Y*Z

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

Which one can be enlarged easier? X? Y? Z?

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. Common platform integrate carrier-grade

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

5. Complete and trusted security solution
