Initial Walkthrough
Access building type
• 
Anticipate difficult zones
• 
Confirm surveyed areas
• 
Check details of area not mentioned on the main coverage map
• 
Check unexpected roaming path
• 
Select Proper Survey Model
Data
• 
Voice
• 
Location
• 
Determine Proper Deployment Characteristics
Dense deployment
• 
Highly mobile (Many cells; high−reliability; fast−moving clients) versus nomadic (temporary
position)
• 
Predictive versus Actual
• 
Specify the tools to complete the survey
Obtain digital floor plans from customer
• 
Spectrum analysis tool like Cisco Spectrum Expert
• 
Professional survey tool such as Airmagnet Survey or Ekahau Site Survey
• 
Define Client Devices to be Deployed
Maximum Tx Power level
• 
Receiver Sensitivity
• 
Antenna
• 
Determine Physical requirements:
Power
• 
Understand cable considerations
• 
Mounting considerations
• 
Outdoor grounding and lightning protection
• 
Consider placement of additional APs for monitoring and sniffing
• 
Checklist of Base Items to ask the Site Survey Provider
Frequency bands to be used: 2.4 GHz, 5 GHz.
• 
Tools to be used in order to complete the survey, such as Airmagnet, Ekahau, and so on.

• 
Auto sampling.
• 
Type of adapter to be used to perform the survey.
• 
The coverage areas that are 'in−scope' or 'out−of−scope', such as stairwells, elevators, electric rooms,
air shafts, mechanical areas, and so on.
• 
Heat map that displays RF coverage for all 'in−scope' areas with coverage set at the target RSSI for
cell edge with a signal legend.
• 
Heat map that displays SNR for all 'in−scope' areas with the target SNR and an SNR legend.
