WiMAX and IEEE 802.16● WiMAX is a subset of IEEE 802.16
● Mobile WiMAX attributes:● High tolerance to multipath and self-interference● Scalable channel bandwidth● Support for MIMO and smart antenna systems● Superior Quality of Service (QoS)● Mobility management● Multicast and Broadcast Service

‘WiMAX’ is addressing a new segment in the telecommunication market
● End-to-end QoS● Hard real-time (voice)
Defined traffic classes● End-to-end service delivery
● Voice, SMS, Gaming, Infotainment● Precise accounting, charging
and billing
POTS, ISDN(B-ISDN, ATM)
GSM, UMTS(HSPA, LTE)
xDSL, Cable
● Best effort, DIFFSERV enabled● Interactive (http, mail)
Streaming, downloads● Access to the plain Internet
● Common web applications, email● Usage classes, flat-rate
“Digital Subscriber Line”
Wi-FiDECT Legacy FMC Internet Age FMC
FMC: new meaning by the Internet
● ‘legacy’ FMC:Access to the same telecommunication services over fixed and mobile networks● E.g. telephony, SMS, MMS
● Services in the Internet are by nature accessible over fixed as well as mobile networks
● Are we done with FMC?● Probably not. But FMC is getting a new meaning. FMC
is allowing telecommunication service providers to provide fixed and mobile Internet access by the same core network infrastructure.
WiMAX deployment evolution
● Today’s broadband providers are tied to their wires● serving consumers and enterprises inside their reach
● A WiMAX access network allows to extend the DSL business servingcustomers without appropriate wires, and additionally also...● addressing customers looking for a more easy-to-use solution,
● providing portable and mobile access
All together may generate a more attractive business case!
The WiMAX Architecture fits to the Internet,… and to DSL networks too.

Conclusion
● FMC in the Internet age addresses the interworking of fixed and mobile access networks.● The same core network for fixed as well as for mobile
access to the services in the Internet● Mobile WiMAX is the wireless access technology for
fixed, nomadic, portable and mobile access to Internet services.
● Mobile WiMAX is enabled to complement a wired broadband network infrastructure by a cellular wireless access technology.
