Objections to WiMAX
A discussion of WiMAX is not complete without taking on objections to
the technology. Before any one can sell a high technology product, they
must first sell the customer on the technology.

Technology sales people invariably encounter objections to the technology they are sell-ing.
The primary objections to WiMAX are:
The answers to those objections are best understood via the Physical (known as the PHY, pronounced "fi") and Medium Access Control (MAC pronounced "mac") Layers. The WiMAX Working Group no doubt were aware of these objections based on experiences with earlier wireless technologies (Wi-Fi, LMDS, MMDS, CDMA, GSM) and have en-gineered WiMAX to fix failures of past wireless technologies.

Technology sales people invariably encounter objections to the technology they are sell-ing.
The primary objections to WiMAX are:
- Interference: Won't interference from other broadcasters degrade
the quality of the WiMAX service?
- Quality of Service (QoS): Wireless is inherently unstable so how
can it offer voice and video services?
- Security: Is WiMAX secure? Can anything wireless be secure?
- Reliability: Nothing can be as reliable as the telephone company's
service (rumored to offer "five 9s" of reliability or 5 minutes of
downtime per year).
The answers to those objections are best understood via the Physical (known as the PHY, pronounced "fi") and Medium Access Control (MAC pronounced "mac") Layers. The WiMAX Working Group no doubt were aware of these objections based on experiences with earlier wireless technologies (Wi-Fi, LMDS, MMDS, CDMA, GSM) and have en-gineered WiMAX to fix failures of past wireless technologies.
