It is an industry alliance of component and equipment
vendors, service providers, and system integrators ensuring interoperability of WiMAX
equipment from different vendors. Like IEEE 802.16, it has various working groups,
each focusing of specific aspects of WiMAX, such as applications, certification, global
roaming, higher-layer networking specifications, and regulatory issues.
In addition to standards bodies and industry alliances dedicated to furthering the
development of WiMAX, there are also several working groups within other standards
bodies, such as Internet Engineering Task Force (IETF), working toward harmonization
of different standards and also influencing the further development of the WiMAX
standard to achieve such harmonization.
European TSI (ETSI) is also involved in ongoing efforts on Broadband Radio Access
Networks, called HiperMAN, which are based on the IEEE 802.16 standard.
Economic Assessment
In earlier sections, we discussed various applications where WiMAX can provide economically
competitive broadband access solutions. In this section, we do a rough economic
assessment of building a WiMAX network to deliver Carrier Ethernet services
to business customers in an urban commercial environment.
