WLAN Coverage Design /
Assessments
WLAN Assessments – Benefits All Over
 Benefits to Customer:
– Understand root causes of potential existing WLAN
problems
– Understand logical path to increasing coverage,
throughput, device support
 Benefits to Partner (services):
– Accelerate development of WLAN Practice expertise
– Immediate credibility via professional technical review of
existing environment
 Benefits to Partner (product sales):
– Drive meaningful discussions about WLAN expansion,
problem resolution, upgrade (11n, etc.)
AirMagnet Confidential
WLAN Assessments – Leading Questions
 Do you ever have WLAN connection or performance
problems?
 Do users need coverage in areas currently not
served? Expansion needed to new building / area?
 Are you considering VoWLAN?
 Are you aware of all the benefits of 802.11n?
 Do you perform regular security sweeps to detect
potential rogue devices or ad-hoc clients?
AirMagnet Confidential
Why Survey?
 Signal propagation is hard to predict
 Interference is impossible to predict
 Walls, doors, elevator shafts, people, and other
obstacles offer varying degrees of attenuation
 It’s absolutely necessary to perform a wireless site
survey…
– To determine how many APs
– To determine placement of those APs
– To determine the channel plan
– To determine to power settings
– To determine which antennas to use
AirMagnet Confidential
What is AirMagnet Survey?

Site survey software for professional RF
and Wi-Fi performance mapping
– Complete, Accurate Wi-Fi Visibility
 See coverage areas, dead spots, and interference
 Measure real-world client performance in terms of
connection speed, packet loss, and end-user
capacity

Key Applications
– Pre-installation site survey
– Post-installation: verify coverage and
performance
– Ongoing network optimization
 Design for additional users, new applications,
performance requirements
AirMagnet Confidential
