"Delivering Carrier Ethernet: Extending Ethernet Beyond the LAN"


A technology based on a widely adapted standard allows for a large number of alternative
solutions, not locking a network operator to a one-vendor solution. It also means
interoperability among different vendor solutions, allowing providers to use products
from different vendors based on where they fit best. The wider acceptance of the technology
also has the benefit of the economics of scale, bringing the cost down.
The key nontechnical benefits of WiMAX are the well-developed standard developed
by a professional organization (IEEE), a large number of vendors offering WiMAX products,
and an industry alliance (WiMAX Forum) with large industry participation to
ensure compatibility and interoperability among these products.
Shortcomings
?–  Limitations of a wireless technology: As compared to other wired technologies,
WiMAX has limitations that come with being a wireless technology. For example,
limited bandwidth, limited range, need for spectrum license and susceptibility to
interference are all limitations of wireless technologies and WiMAX is no exception.
WiMAX stacks up better than may other wireless technologies in many of
these limitations.
