Since
netIQ
doesn't have a Qcheck/Chariot endpoint for WinCE, we can't use those tools
to check out wireless performance. Instead we've had to use the more
limited tool set that is available for WinCE/PocketPC devices.
因为netlQ没有一个可运行在WinCE上的Qcheck/Chariot软件，我们不能使用这些工具来检验无线网络的表现。我们不得不改为使用可在WinCE/袖珍PC上运行的更有限的工具。
Here's a diagram of the test setup:
如下为一个测试设置框图：
Equipment Details:
设备详细资料：
·
Ethernet Client:
·
以太网客户端
"Beige box" Celeron 300A, 128MB, Win98
or
"Compaq 5451, AMD K-6 500MHz, 92MB, Win98SE
·
Wireless Client:
·
无线客户端
Compaq 1650 (Pentium 266), 64MB, Win98SE
·
Access Point:
·
无线接入点
SMC2655W
(Chosen because it has no throughput degradation with WEP enabled and
strong signal vs. distance performance.)
选择SMC2655W是因为它在WEP启用时没有吞吐量降级，和长距离时信号较强的性能。
All tests are run at four different locations or test
sites:
所有测试在4个不同地点或测试站进行：
·
Condition #1: AP and wireless client in same room, approximately 10 feet
apart.
·
条件＃1：接入点和无线客户端在同一房间，大约分开10英尺。
·
Condition #2: Client in upper floor room directly above AP, approximately 15
feet apart. No metal ductwork between AP and client.
·
条件＃2：无线客户端在接入点楼上正上方，大约分开15英尺，在接入点和客户端之间没有金属管道系统。
·
Condition #3: Client on same floor as AP but in another room approximately 50
feet away. Walls, but no metal ductwork between the client and AP
antennas.
·
条件＃3：无线客户端和接入点在同一层楼但在大约50英尺以外的另一房间，隔墙但在接入点和客户端之间没有金属管道系统。
·
Condition #4: Client on upper floor at opposite end of residence,
approximately 55 feet away. Walls, floor, and probable metal ductwork
between AP and client.
·
条件＃4：无线客户端在接入点楼上住房相对尽头，在大约55英尺以外，隔墙、地板，在接入点和客户端之间可能有金属管道系统。
TCP Response
传输控制协议响应
We use the Ping utility that's part of
Cambridge
Computer Corporation's free vxUtil package. 10 pings are done
and the average and maximum ping times recorded.
我们使用剑桥计算机公司的免费vxUtil软件包中的Ping命令。执行10次Ping，记录平均和最大的Ping时间。
TCP Transfer Rate (Throughput)
传输控制协议传递速率（吞吐量）
We use
Cambridge Computer
Corporation's vxFTP FTP Client ($25 after free 30 day
evaluation). We download an approximately 1MB file from a PC on the
Ethernet LAN that's running
3Com's free
3CDaemon as an FTP server multiple times and record the time and
transfer rate reported by vxFTP for each download. The reported
Kbytes/second is converted to Mbits/second as follows:
我们使用剑桥计算机公司的vxFTP软件的FTP客户端（免费30天评估后25美金）。我们多次从运行3Com公司免费3Cdaemon软件做FTP服务器的以太网上一台PC机上下载一个大约1MB的文件，记录每次vxFTP报告的时间和传输率。报告中的千字节/秒按下述方法转换成兆比特/秒。
Transfer rate (Mbits/sec)=
(Transfer rate in Kbytes x 8) / 1024
传输率（兆比特/秒）＝
（以千字节为单位的传输率×8）/1024
This test is usually run both with and
without WEP enabled to check for WEP speed degradation.
此测试通常在WEP启用或不启用时各进行一次，以检测WEP速度降级。
NOTES
注意
· vxFTP rounds transfer times to the nearest second
·
vxFTP运行传输时间近似到秒
· We suspect that the Transfer Rate method may be under-reporting
the actual maximum Transfer Rate. Let
us know if you have other suggestions for performing this test.
·
我们怀疑传输率方法可能在报告的实际最大传输率之下。如果你有进行这项测试的其他建议，请告诉我们。
