Abstract :
Wireless communication systems today become a trend for the information
society. This is not apart from the communication needs with high mobility and
low cost. One of them is Wireless Local Area network with IEEE 802.11 standard.
WLAN is a communication technology that uses radio transmission utilizing free
space as a transmission line. Transmitted signal strongly influenced by distance,
frequency, power transmitter, receiver sensitivity, and antenna gain.
In the process of transmitting data from the sender to the receiver occurs
loss, in order to avoid loss it needs a good Quality of Service, and wide coverage
area. The purpose of this study is to analyze the QoS data, calculate coverage
area and receiver power and than compare the results of theoretical calculations
with the measurement results.
The analysis result shows the average throughput value for each data rate
is 6 Mbps, 15 Mbps and 35 Mbps of 383.8 kbps, 328.2 kbps and 329.8 kbps. The
result average delay is 5.28 ms, 4.81 ms and 4.66 m. The result average packet
loss 2.83%, 2.66% ms and 2.16%.The result average jitter 0.036 ms, 0.032 ms
and 0.014 ms. With a maximum measured coverage area of 123 meters, in line of
sight conditions. The difference between theoretical receive power and measured
receive power between 13.52 % to 28.82 % is found.
