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

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

Manual Setup
Automatic 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
1. Power-on or unlock the phone
2. Handset automatically validates
network and initiates connection
Yes! Here it is!

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
