Wireless Tests

802.11g wireless performance test results are presented in the table below:

Test Conditions: - WEP encryption: DISABLED - Tx Rate: Automatic - Power Save: Disabled - Test Partner(s): Fujitsu Lifebook P-2000F w / Internal Broadcom wireless network card			Firmware/Driver Versions : AP f/w: V 3.60(HI.1) Wireless client driver: WinXP 3.10.39.7
Test Description	Connection Rate	TCP-IP Transfer Rate (Mbps)	Response Time (msec)	UDP stream
				UDP Throughput (kbps)	Lost data (%)
Condition 1	54 Mbps	15.7	1 (avg) 1 (max)	500	0 %
Condition 2	36 Mbps	15.8	1 (avg) 1 (max)	500	0%
Condition 3	1-5 Mbps	7.5	2 (avg) 2 (max)	485	0%

Figure 16 is a Chariot screen snap after the completion of Test 1, which represents an ideal environment, with the G-2000 and client in the same room. Except for two brief drops, throughput is fairly constant at 15.7Mbps. This performance is typical of competitive products.

Test 2 is a typical environment where the client is 40 feet and a few walls away. Figure 17 shows a general slowdown in speed and more frequent sudden speed drops. The client showed that the connected rate had dropped to 36Mbps, but the actual throughput - 15.8Mbps - is no worse than Test 1.

Test 3 represents a worst-case scenario with the client separated by some formidable barriers, such as brick work and earth that drastically diminish the signal. The connection rate bounced between 1 and 5Mbps and it took several tries just to find a location that didn't drop the connection altogether. Figure 18 shows that Test 3 completed with an average transfer speed 7.5Mbps, which was higher than the connection rates shown by the client. You can also see that throughput variation was much higher than for Test 1 and 2.
