Abstract—The popularity of IEEE 802.11 networks comes
with its low cost, high data rate and seamless handoff. With
heavily utilized infrastructure based wireless networks, number
of users are increasing rapidly which makes available
unlicensed spectrum band more congested. Moreover, most of
the IEEE 802.11 standards (b/g/n) operate on 2.4 GHz which
has subject to interference with other services like Bluetooth,
sensor networks and cordless phones. Hence, the performance
of IEEE 802.11 MAC should be enhanced with respect to
interference and spectral scarcity. In general, IEEE 802.11
networks operate on either DCF (Distributed co-ordination
function) or PCF (Point co-ordination function) mode. This
research paper mainly focuses on PCF mode IEEE 802.11g
standard and explains the necessity of amendment in terms of
frequency, throughput, net bit rate, maximum indoor range
and maximum output range. OPNET Simulator is used to
calculate network load, throughput and medium access delay.
Moreover, calculated performance metrics are compared with
different user probability for IEEE 802.11g networks.
Index Terms—IEEE 802.11g, MAC, throughput, network
load.
