•
•
•
•
•
•
•
•

>
Access from any device and location
Single bill and authentification
Not only throughput but QoS
New multimedia services
Mobile Triple play (VoD, PVNS, iPTV, …)
Mobile Office / business, Push Mail
Presence, Communities
SME VPN
Push to talk
Mobile network Gaming
Specific Vertical markets
(Airports, transports, …)
Operators look for solutions enabling
•
•
•
•
•
•
•
•
•
“Unlimited” voice
High Throughput on the move
Mobile TV
Low latency
End-2-End QoS
Simplified / flat Architecture (IP Based )
Affordable (like DSL)
Efficient Backhauling
Maximize Site Reuse
… At the lowest price
Expectations accelerated by demand
for Multi-Media Content Delivery and IMS

What is WiMAX
(Worldwide Interoperability for Microwave Access) ?
>
It’s Broadband : typically 25 Mbps/cell
>
It’s IP native
>
It’s Point-to-Multipoint Microwave : up to 15km
>
It’s Non Line of Sight
>
It’s like Cellular coverage design
>
It’s Standard-based : IEEE 802.16
>
It’s cost-effective : CPE below $300
>
It’s supported by more than 370 industry players
to make it interoperable

Why 16e ?
> Higher
•
performances than 16d
The right technology for BWA
–
–
Flexibility & Allocation
Radio Performances
> Mobility
> Smart
•
16e permits innovative offers based on nomadicity and Wireless DSL
Common network for large & innovant end user offer
> 16e
•
Features making Indoor CPE & PCMCIA deployment feasible developed only in 16e
Smart Antennas, Sub-channelisation
> Only
•
Devices (PCMCIA etc..) : only 16e
Mass Market only compatible with 16e
> Radio
•
mechanisms only with 16e
& 16d air interfaces are NON COMPATIBLE
2 layers network (1 carrier 16d, 1 carrier 16e) required for adressing CPE 16d and CPE 16e
> Interoperability
•
is driven by Nomadism & Roaming requirements, therefore 16e
16d will likely remain proprietary or with reduced interoperability
