52-8 Industrial Communication Systems
52.5.2 WiMAX-3GPP Integration
The third Generation Partnership Project (3GPP) unites telecommunications standards bodies as organizational
partners, originally established to produce technical specifications and technical reports for a
3G mobile system based on evolved GSM core networks and the radio access technologies that they support
(i.e., universal terrestrial radio access [UTRA], both frequency-division duplex [FDD] and timedivision
duplex [TDD] modes) [16]. The 3GPP-WiMAX integration presents interworking approaches
by which a 3GPP operator employing 3GPP technologies (GSM/GPRS, EDGE, UMTS, and/or HSDPA)
provides subscriber access to 3GPP PS and to the IEEE 802.16 packet service plane. Tightly and loosely
coupled interworking of WiMAX with 3GPP entails tightly coupled and loosely coupled interworking
approaches between the WiMAX AN and the 3GPP core network taken by 3GPP in standard TS 23.234.
While originally developed for WLAN, the ideas in TS 23.234 are now the basis for ongoing 3GPP
discussions on extending the scope to include other IP-based access technologies, including WiMAX.
52.6 Conclusion
While WiMAX may seem as technology competing with existing broadband alternatives such as DSL
and cable, it rather has a distinctive, complementary place in the modern broadband Internet access offerings.
The WiMAX already has established itself as a broadband alternative of choice in rural and remote
areas, with the possibility of backhaul and overlay for other technologies as well. Regardless of the predictions
made regarding this technology, it is already obvious that the times of WiMAX are yet to come.
