Carrier Core Integration Cellular Integration Supported Types of Locations and Use Cases Manageability and Carrier Business Intelligence Scalability Security


AT&T

• Wi-Fi Domain Vendor – direct relationship• Certified into AT&T’s proprietary back office• Cellular Co-location – sole vendor• Next Generation Hot Spot (“ReadyZone”) – sole

vendor• Temp Events – sole vendor (except where there is

a network in place)• Large Venues – we are going in trials in

September• Cellular Underlay – in discussions with AT&T,

moving to pilot• Integration with DAS – in discussions with AT&T

Why do Carriers Need Wi-Fi?

• iPhones made the Internet Mobile• FaceTime only works on Wi-Fi• iCloud only works on Wi-Fi• Cellular Carriers Need Wi-Fi

End User Experience To ensure cellular network performs To lower the cost / bit To generate new revenue from new

apps To support iPhone apps which do

not work on cellular (iCloud, FaceTime, some AppStore downloads)

• Cable Operators Need Wi-Fi To deliver broadband to their

customerswhen they are not at home or work

The World of Wi-Fi

• Enterprise WLAN systems were designed…. Before the iPhone or iPad, or Android, with no notion of offload Before AT&T network was congested Prior to Groupon and clueless on advertizing Before Facebook and oblivious on social networking Before Netflix and Hulu … Even Before YouTube (and that was a while ago)

Before “The Cloud”

• The World has changed…. Carriers are moving into Wi-Fi• But the Enterprise Class WLAN has not changed….• BelAir Networks has designed a solution for cellular carriers based

on Current Cellular Carrier needs

Where is Wi-Fi Needed?

1. At Home Apple and Service Providers compete for the in-

home distribution

2. In Venues/Enterprises with few visitors VAR business. Service Providers will come later

3. In Venues/Enterprises/SMBs with large proportion of visitors

Huge Priority now

4. In Outdoor areas where there is poor mobile coverage or capacity

Huge Priority Now


Priority Areas for Service Providers Now

StadiumsSpecial Events

Downtown and High User Concentration

Areas

SMB’s

Restaurants

Commuting

EducationInstitutions

Hospitals andDoctor Offices

Shopping (Retail)

Hotels, Airports orConvention Centers

Areas of high VISITOR concentration – Indoor and Outdoor


Vision of the Converged Mobile Network

• Wi-Fi and Small Cells are two sides of the same solution: massive mobile capacity increase at lower cost / bit Both are here to stay and will coexist in the next gen mobile network Integration of Wi-Fi with picos and with DAS Harmonized solution Seamless network entry

• Consistent and Common Authentication Policy Management Use cases requiring capacity (i.e. hotels, stadiums, hot zones)

• Smart and secured at the Edge• Consistent Management tools• HotSpot 2.0• Two grades of Mobility

Short term no session mobility Long term session mobility an option coexisting with the no session

mobility method


WE HAVE DEFINED AND IMPLEMENTED THE WI-FI

SOLUTION FOR CARRIERS!

Carrier WI-FIArchitecture


BelAir Networks Architecture Key Attributes

1. Supports all Use Cases Covers all carrier use cases over a single architecture (i.e Colo, underlay, SMB,

Large Venues, Temp, Strand) Covers all RF environments (reach, interference, capacity)

2. Scalability Scales to a national network – AT&T Wi-Fi covers US Authentication scalability to over 500M users Management scalability to over 1 million Access Points

3. Mobility Wi-Fi to Wi-Fi, band steering, Wi-Fi to cellular

4. Security Edge security for the carrier visitor network. PEP in the Access Points Enterprise security for the large venues

5. Management Management and BI geographical, map based, visual with carrier Wi-Fi related BI

6. Integration with Cellular Cellular core: narrowband CDMA, UMTS, LTE

7. Supports Carrier Wi-Fi advanced services Real time LBS, Mobile Video, iCloud, etc.

8. Consistent with Hotspot 2.09. Flexible to allow several OEM core networks, more or less mobility
