Title:
Performance
Analysis of WiMax
Abstract: WiMax, a broadband
wireless access
technology, is based on World Interoperability for Microwave access. It
provides the last-mile solutions for different applications up to the
maximum
distance as compared to the other wireless technologies with better
coverage
and data rates. Basically, it is an IEEE 802.16 standard termed as a
wireless
MAN and the subset of this standard is 802.16a called as WiMax. It is
developed
by ETSI (European telecommunication standard institute) offering data
rate
up-to 100Mbps and its transmission range is up-to 51km. WiMax, wireless
MAN
(Metropolitan Area Network), uses directional antennas to maximize the
transmission range and coverage in LOS (Line of Sight) and NLOS (Non
line of
Sight). It uses both licensed and unlicensed frequency bands having
spectrum
range from 2GHz-66GHz. This
innovative technology is used to provide broadband access with high
data-rate for residential as well as enterprise use with low cost
infrastructure. Both continuous and busty traffic can be accommodated
through
this wireless technology. The project aims to discuss its performance
analysis
on the basis of different parameters like QoS, modulation, data rate as
compared to other wireless technologies like 3G, GPRS etc. The work
focuses on
extensive background study of WiMax, its standards, technical issues,
network
consideration, Physical layer & MAC layer, its architecture and
future
enhancements in case of full mobility, coverage, high transfer rate in
WiMax.
Further investigation in my work will be used to explore different
modulation
schemes such as OFDM, OFDMA. Scalable Orthogonal Frequency Division
Multiple
Access (SOFDMA) is used in mobile WiMax will be used as full mobility.
In a
nutshell, this cost effective broadband wireless having throughput of
70Mbps
technology is an alternative to DSL, fibre optics and cable modems. In future, WiMax will be a big
intimidation to cellular technologies due to more capacity of voice,
data, QoS,
coverage, and cost etc.
