1 WLAN Validation 1 Motorola Public Document Classification, October 2011 MODULE 18 WLAN VALIDATION

2 WLAN Validation 2 Motorola Public Document Classification, October 2011 At the end of this module, you will be able to: WLAN Validation 2 Objectives –Identify the four phases of WLAN validation –Distinguish between an active site survey and a passive site survey –Describe site walkabout guidelines –Identify the prerequisites for a performance test –Identify the questions answered during a performance test

3 WLAN Validation 3 Motorola Public Document Classification, October 2011 Phases of Validation

4 WLAN Validation 4 Motorola Public Document Classification, October 2011 Phases of Validation - Overview Site survey validation Performance testing Spectrum analysis (*) Security testing (*)

5 WLAN Validation 5 Motorola Public Document Classification, October 2011 Site Survey Validation

6 WLAN Validation 6 Motorola Public Document Classification, October 2011 Summary PurposeVerify RF Characteristics meet QoS requirements of network design PrerequisitesAPs are installed and operating Validation site survey phasesPassive LANPlanner / Site Scanner site survey (RF Monitoring) Active LANPlanner / Site Scanner site survey (AP performance) ConsiderationsA precise validation survey must combine active and passive site surveys

7 WLAN Validation 7 Motorola Public Document Classification, October 2011 Passive Site Survey Basics Survey instrument is a laptop or tablet –with LANPlanner/Site Scanner or an equivalent survey tool Survey instrument measures RF energy Survey instrument generates no WLAN traffic

8 WLAN Validation 8 Motorola Public Document Classification, October 2011 Passive Site Survey Basics 1.Load site floor plans 2.Mark your starting point 3.Enable RF sensor 4.Walk and mark walk halls, rooms, and open spaces 6.Insert reference points 7.Save survey data

9 WLAN Validation 9 Motorola Public Document Classification, October 2011 Walkabout Guidelines (1 of 3)

10 WLAN Validation 10 Motorola Public Document Classification, October 2011 Walkabout Guidelines (2 of 3)

11 WLAN Validation 11 Motorola Public Document Classification, October 2011 Walkabout Guidelines (3 of 3)

12 WLAN Validation 12 Motorola Public Document Classification, October 2011 Active Site Survey Measures both RF energy... and a continuous data stream... between an AP and the survey instrument

13 WLAN Validation 13 Motorola Public Document Classification, October 2011 Interpret Survey Results

14 WLAN Validation 14 Motorola Public Document Classification, October 2011 KEY GUIDELINE Ensure that the survey tool sampling interval is greater than the AP beacon interval

15 WLAN Validation 15 Motorola Public Document Classification, October 2011 Performance Testing

16 WLAN Validation 16 Motorola Public Document Classification, October 2011 Summary

17 WLAN Validation 17 Motorola Public Document Classification, October 2011 Basics Requires both the wired and wired segments of the WLAN Requires connectivity to application servers and network resources Requires an instance of each client device type and model supported by the network Requires an instance of each end-user application supported by the network

18 WLAN Validation 18 Motorola Public Document Classification, October 2011 Initial Checklist

19 WLAN Validation 19 Motorola Public Document Classification, October 2011 Application Performance Test Checklist

20 WLAN Validation 20 Motorola Public Document Classification, October 2011 Roaming Performance Test Guidelines During a roaming test, duplicate the maximum roaming speeds users are likely to attain Use a packet trace tool during roaming tests, particularly for latency-sensitive real-time applications

21 WLAN Validation 21 Motorola Public Document Classification, October 2011 Load Performance Testing Determine: Do applications meet QoS requirements when the WLAN is under a typical expected load? Recruit end users or an extended test team to simulate site usage scenarios Employ a centralized management system to monitor network and application performance Interview users to discover the perceived performance of individual applications

22 WLAN Validation 22 Motorola Public Document Classification, October 2011 WLAN Validation – Review Use appropriate tools (LANPlanner, SiteScanner, etc.) to validate RF performance Be sure to use Walkabout Guidelines to validate quality of RF performance Ensure site survey tool sampling interval is greater than the AP beaconing interval During roaming test, be sure to duplicate the maximum roaming speeds users are likely to use.
