Macro

Femto SP WiFi

• Macro Networks Mobile Internet Economics – significant incremental cost of production

Ranges from ~$2/GB (3 carrier config) to ~$6/GB (1 carrier config)

• Indoor offload solutions deliver very low incremental cost of production, similar to fixed Internet economics

• As consumption rises, becomes more cost effective to offload traffic:

Compared with a 1-carrier macro cell, femto delivers improved economics for users with >750 MB/mo consumption

Compared with a 3-carrier macro cell, SP WiFi delivers improved economics for users with >500 MB/mo consumption


• Dedicated low power and low capacity licensed radio access point (3G/LTE) that connects with existing mobile core network via an existing broadband connection

• Small cell benefits Standard Architecture Improved indoor coverage for higher voice quality and data rates Ubiquitous service and mobility with macro network Cost reduction with macro network and backhaul offload New services (homezone, enterprise integration)

• Multiple target segments with all having specific requirements

Solution rolled out nationally by June 2010 ~800k units sold >600k active Units are installed by consumers 92% are completed without AT&T’s involvement thanks to our ZTPS [Zero-Touch Provisioning System] 1.8M calls / 7M minutes handled daily 2.2 TB of mobile data offloaded Inserting ASR5K to replace existing Access Controller

Project Facts • Challenging project from the start: specs being defined ‘on the go’ in a nascent segment of the industry

• True ‘Whole Offer’ for Cisco

• A lot of new development was required, working with multiple partners (including ip.access)

• Fantastic dedication by the Engineering team!

• ‘Best Commercial Rollout’ award at Femto World Summit in London (June 2010)

• Led to ASR5K insertion and future expansion opportunities



• Small Cells are becoming mainstream for the service providers

• Cisco has extensive residential small cells experience including dense network deployment

• Cisco Small Cells solution is evolving to address new markets and use cases Open access public venue Hybrid access enterprise

• Key technology focus include New multi-mode AP Self Organising/Optimizing Networks


Focus shifting from wireless technology to connectivity Most devices will have Wi-Fi.

Increased emphasis on dynamically selecting the best network(s)

We get asked: If I have LTE, do I need Wi-Fi ? Answer: YES

We get asked: if I have Wi-Fi, do I need LTE ? Answer: YES

Wi-Fi and Cellular are complementary SPs are thinking: Cellular for voice and premium service; Wi-Fi for data


Okay: I need both. But tell me why I should integrate them ?

Integration Benefits in Outdoor/Metro Leverage Site Acquisition, Power, B/Haul

Minimize public concerns related to aesthetics

Integration Benefits in Indoor/Enterprise Minimize installation costs (wiring, etc)

Reduced costs

Other benefits Dynamic load balancing between Wi-Fi and Cellular

Leveraging mobile attachment to one radio to enhance connectivity in another radio


SP Wi-Fi Model • SP owns/operates Wi-Fi • Hotspots, venues (malls,

stadiums, etc)

Enterprise Wi-Fi Model • Enterprise

Wi-Fi Cellular

Transmitter Receiver

1. Wi-Fi Noise: Out of Band Emissions from Wi-Fi Transmitter in Cellular Band. Wi-Fi transmitter generates too much noise in the Cellular Band

Wi-Fi Cellular


2. Wi-Fi Blocking: Wi-Fi In-Band can cause Cellular Receiver to “block” if Wi-Fi signal is too strong.

Cellular Wi-Fi


3. Cellular Noise: Out of Band Emissions from Cellular Transmitter in Wi-Fi Band. Cellular transmitter generates too much noise in the Wi-Fi Band

Cellular Wi-FI


4. Cellular Blocking: Cellular In-Band can cause Wi-Fi Receiver to “block” if Cellular signal is too strong.

Ongoing study to measure all four cases. Most likely this will limit the maximum transmit power of Cellular.


• 3G radio and Wi-Fi Radio have separate IP addresses.

• AP 3600 will “bridge” 3G traffic.

• Cellular and 3G radios will mark packets individually

• VLAN tags • 802.1p markings • DSCP markings

• Cellular and 3G radios may rate limit individual streams. e.g.,

• AP rate limits on per SSID basis

• Wi-Fi traffic brought to GGSN via EWAG/IWAG

• Separate security model for Wi-Fi and Cellular Traffic

DTLS (Wi-Fi ) and IPSec (Cellular)

• Similar network integration for 4G

• PMIPv6 connectivity from WLC is another alternative for Core network integration
