12. WLAN Coverage Design / Assessments

13. 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

14. 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

15. 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

16. 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
