Interoperability Testing and Market Feel
While the 802.16e standard could be completed in late 2005, it does not necessarily suggest that the technology will then be ready for commercial deployment. Even for the 802.16d standard, multivendor interoperability tests, commonly referred to as ‘Plugfests’, are yet to occur, although they are expected to begin later this year.
Interoperability testing always takes longer than anticipated, in particular if an entirely new standard is being tested and if companies not normally accustomed to this type of activity are involved. Assuming that interoperability testing is successful and that commercially viable solutions (e.g. data cards) are available, potential operators could then take months conducting field trials before moving to a market trial and then potentially a wider-scale commercial roll-out.
It is interesting to note that current plans for WiMAX plugfests are to certify equipment against one of the many WiMAX targeted profiles. Since the Forum targets multiple profiles for different regions and applications, many interoperability activities will be required. Additionally, end-to-end plugfests cannot be a reality until WiMAX base stations and WiMAX CPEs are available. If history is a guide, the WiMAX base stations will be ready for interoperability testing well before the CPEs will be ready.
Uncertain Economics
Like with other wireless technologies, the economics of using WiMAX to offer fixed wireless services in regions of the world where wireline deployments have not taken place or where there is little competition are attractive. By eliminating the need to deploy copper or fibre, an operator can significantly reduce its upfront capital expenditures while at the same time reduce the risk of service disruption due to vandalism or theft of the buried cabling.
Once consumers self-install the CPE, the deployment cost advantages become even more compelling. It is not clear if the same can be said for other market opportunities, especially when the network operator is designing its network to support seamless mobility and voice - far more base stations are required, regardless of the air interface that is used. However, if the operator deploys its WiMAX network in selected, albeit geographically large, areas where portable/mobile broadband data
traffic is highest, and if the operator does not attempt to deliver ubiquitous coverage within that area, its cost structure will be reduced.
Put simply, deploying a mobile network is not an inexpensive proposition, and with an abundance of mobile operators in most countries, these regions may not be able to support another greenfield mobile operator. These regions could, however, support a service that differentiated itself by offering higher data rates, with the tradeoff coming in the form of reduced coverage and lower quality of service -seamless handoffs, high-speed vehicular support, etc.
WiMAX Effect
WiMAX Solutions
IEEE 802.16 is an emerging suite of air interface standards for combined fixed, portable and MBWA. Initially conceived as a radio standard to enable cost-effective last-mile broadband connectivity to those not served by wired broadband such as cable or DSL, the specifications are evolving to target a broader market opportunity for mobile, high-speed broadband applications. The realization of a low-cost, broadly interoperable wide-area data network that supports portable and mobile usage could have significant end-user benefits.
Imagine a radio access network that provides broadband access to users at home, in the office, in areas underserved by wireline services and even to users on the move equipped with portable devices like laptops, PDAs and smart phones. WiMAX can provide a flexible radio access solution that offers these features, based on an attractive full IP architecture delivering the capacity required to support wireless broadband services.
WiMAX is at the centre of the emergence of new market and technology opportunities. The widespread deployment of high-speed Internet at home has opened the door to the introduction of new services, such as video, audio, gaming and e-commerce. Today, the availability of portable devices like laptops, PDAs and smart phones is generating interest in providing similar services under nomadic conditions.
After the emergence and wide acceptance by users of Internet, broadband and mobile services, we can anticipate a future need for nomadic broadband wireless services. By addressing multiple market segments through the standardization and interoperability efforts of the WiMAX

Forum, volume production of WiMAX Certified equipment will become possible, driving down the total cost of ownership and opening up new opportunities for the delivery of broadband services to bridge the digital divide.
WiMAX access can be easily integrated within both fixed and mobile architectures, enabling operators to integrate it within a single converged core network, thereby providing new capabilities for a user-centric broadband world.
