2. What is Femtocell
Femtocells are small cellular base stations that plug into a residential DSL or cable modem
Use license spectrum
Attach to cell phones in the same manner as cell phones attach to macro base stations
Customers can use existing cell phones with the Femtocells
Mobile voice and data services are carried back to the wireless operator’s core network via the residential broadband connection
Guaranteed coverage within the home
Higher quality than typically experience on the macro cell at home
Reduce churn
Frees up cell tower capacity
Carriers get more from their existing spectrum

5. Mobile consumers are inundated with choices and decisions daily
What’s Behind the Femtocell Move? Mobile Subscribers, Mobile Lifestyles, and Mobility-enabling Providers
Consider the Impact of the Apple iPhone
The iPhone represents only 2% of the smartphone market.
But it already drives 70% of mobile Internet usage with its full-feature, easy-to-use iPhone browser.
It’s all about understanding a population that embraces mobile and digital lifestyles.
Mobile consumers are inundated with choices and decisions daily

6. What Mobile Subscribers Want in Services, Security, and Choices
Today and Tomorrow’s Users
What mobile subscribers want:
Seamless quality of service
Exceptional quality of experience
Knowledge that their mobile sessions are secure
Access from anywhere to anywhere on any device 6

7. The Mobile Lifestyle -> Unprecedented Data Growth
Extracted from Heavy Reading: Comments made in public forums provide evidence of unprecedented data traffic growth:
T-Mobile said 3G data volume in Q increased 57% from Q
Telefonica-O2 said it saw doubling of data volume every quarter in 2007.
Ericsson says that in 3G networks monitored by Ericsson, total data traffic now exceeds voice traffic. By August 2007, more than 60% of WCDMA traffic was data.
Nokia Siemens Networks sees greater volumes of data than voice in several European HSPDA networks. In some networks, data accounts for 80% of the traffic volume.
AT&T Mobility said in February 2008 that wireless data traffic was four times greater in 2007 than 2006

9. Operator Considerations for the Femto Integration
Throughput bottleneck will shift from the Access Network to the core – first point - Femto Gateway
The Operator’s Core must evolve to keep up
Need for flatter network architecture - Network element consolidation/elimination – eg. Platforms – ATCA, Direct tunneling
More devices, more sophisticated applications -Security and QoS requirements at the edge will be key factors
Access-agnostic core - Mobility between networks (Mobile IP, GTP)
Huge bandwidth and scale requirements for the Femtocell gateway
Direct tunneling - Bypassing the serving gprs node in the data path
Growing demands on the Femto Gateway standard to evolve!

12. NextPoint’s Integrated Border Gateway for Femtocell Deployments: A Unified Quality of Experience
In conclusion, NextPoints solutions help the operators provide a unified quality of experience.
by enabling seamless subscriber mobility as the packet core evolves
by providing consistent and scalable secure access,
By ensuring a positive voice, data and multimedia experience through a policy driven QoS scheme as the mobile data explodes
and finally protecting the carriers infrastructure from existing and new attacks In summary, operators need a migration plan as their network evolves…deploying NextPoint’s IBG solutions helps the operator future proofs their investments.
