WiBro vs WiMax
•
Physical Layer Differences.
•
MAC Layer Differences-handoffs.
•
Network architecture Differences.
Advantages
•
Low cost and High Data rate.
•
The technology will also offer Quality of Service.
•
•
•
The spectrum it uses is licensed and
correspondingly protected from un-licensed use.
WiBro can be considered as “Mobile WiMax”
which can be used while the receiver is in motion.
High network capacity
Disadvantages
•
The proprietary nature of WiBro and its use of
licensed spectrum that may not be available
across the globe may keep it from becoming an
international standard.
•
Interference.
Future Plans
•
•
WiBro Expected to be widely deployed all over
the world in a few years.
Some Telcos in many countries are trying to
commercialize WiBro.
