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.)

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
