people are
 Reduced data capacity edge of
cell
 Sub-optimal delivery of high BW to
POPs
 High CapEx/OpEx: $400K
 Poor spectral efficiency
Dealing with non uniform coverage
Wi-Fi/Femto/Pico
 Delivers targeted coverage and
capacity
 Support high-capacity data
 Precision delivery of high BW to

ANDSF Solution Approach
 Off-load UMTS/LTE traffic to WiFi provided that user experience on WiFi will be equivalent to
microcellular
 Device client is critical in solving the problem
– Client enables managed WiFi offload where SP controls criteria and conditions for traffic offload
– Access type
– Access and network conditions
– Location
– APN
– Device
– Roaming status
– Time
– Data usage
– Application
– Subscriber status/service
– TFT (5 tuple filters)
 The client can also expose info required to collect analytics
 Network needs to provide necessary triggers to enable these policies
Cisco and/or its affiliates. All rights reserved.SP WiFi & Small Cell Cisco Public
ANDSF List of Usecases
1. Standard ANDSF and S14 interface
2. Initial policy download including filtering based on location
3. New SSID list based on location change
4. Connection fallback on poor access conditions
5. Control of WiFi access for roamers
6. WiFi access for over the quota prepaid users
7. Selective traffic routing
8. Analytics

Imagine a World…
 You Enter a Venue…
 …and get onto the Wi-Fi network as simply, seamlessly, and securely
as cellular
 no SSID, no username, no password, no Web Auth, etc.
 a new customer can immediately sign-up online at the venue
 You are Automatically Notified of Special Services
 pre-installed apps automatically launch upon notification (or can download new
apps as needed from a local server)
 You have Instant Access to cool venue specific services and
content
 Indoor Maps, Product Finder, Call for Help, Product Reviews, Loyalty info, etc.
 This is the Promise of Hotspot 2.0
Cisco and/or its affiliates. All rights reserved.SP WiFi & Small Cell Cisco Public
Sample Scenario
Hotspot 2.0
Client
Regular
Client
Manual Setup
1. Power-on or unlock the phone
2. Select Wi-Fi network
(vulnerable to rogue AP)
3. Go to WebAuth
4. Browse webpage and enter right
credential, usually ID/PWD
5. Choose roaming plan
6. Start Internet
Automatic Setup
1. Power-on or unlock the phone
2. Handset automatically validates
network and initiates connection
• Makes Wi-Fi easy-to-use and secure (like cellular)
• 802.11u enabled network is compatible with non-11u devices!

AT&T 3G MicroCell
• AT&T 3G MicroCell launched April 2010
http://www.wireless.att.com/learn/why/3gmicrocell/
• Largest 3G femtocell deployment worldwide
• True zero-touch provisioning
Over 90% of femto installations done without customer care intervention
Fully automated provisioning and management control
BEST COMMERCIAL FEMTO LAUNCH
AT&T’s 3G MicroCell National Deployment
“AT&T’s 3G MicroCell deployment with Cisco caught the judges’ eyes for two crucial reasons. First and foremost, it emphasized the
importance of the customer at the heart of the femtocell experience, positioning technology very much as an enabler, rather than an end
in itself. Secondly, the deployment is on a national scale, which given the US market’s size adds an additional layer of complexity”,
agreed the judges.

WiFi Network Observations
 Cisco worked with a Canadian Telecom Service Provider to install and operate a WiFi
network for the Montreal F1 event
– The network covered 2 bleachers, 2 VIP areas; roughly 50 K Square feet
– 50 APs (3600 and 1552 from Cisco)
– Fiber backhaul – 200Mbps
 Network statistics over 3 days:
– Just under 3,300 users at peak (race day)
– Peak Upstream Bandwidth = 52Mbps (race day)
– Peak Downstream Bandwidth = 28 Mbps (race day)
– Total traffic over three days 144Gb
– Average users at the same time = 2,200

First and foremost, it emphasized the importance of the customer at the heart of the femtocell experience, positioning technology very much as an enabler, rather than an end in itself. Secondly, the deployment is on a national scale, which given the US market’s size adds an additional layer of complexity”, agreed the judges. London, England - June 23, 2010
