carrier wi-fi meets small cells with china mobile
DESCRIPTION
We would like to invite you to an exclusive webinar entitled 'Carrier Wi-Fi Meets Small Cells', presented by Maravedis-Rethink and featuring our guest speaker, Mr Tao Sun, Program Manager for Network Technology at China Mobile, the world's largest mobile operator, which has an ambitious program for TD-LTE, small cell and Wi-Fi deployment. Tao Sun has worked in the small cell area for four years and drafted the enterprise femtocell specification for China Mobile, as well as co-leading the small cell project in the NGMN. He is heavily involved with the carrier's Nanocell project, which is focused on integrating small cells with Carrier Wi-Fi. China Mobile already deployed about 4 million WLAN APs in the network, aiming at 6 million Aps in future. It also plans to deploy 200,000 LTE base station in 2013. Nanocell will play important roles in China Mobile network as a cost-effective broadband solution. The webinar will offer a unique opportunity to gain details and insights into this important project, which will break new ground in LTE deployments, integrated small cells and Carrier Wi-Fi. Other topics will include small cell standards, the use of unpaired spectrum, and the future evolution of the HetNet.TRANSCRIPT

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

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
