  • Industry vertical
  • Customer questionnaire
B.  Identify regulatory issues:
  • Country codes (-e, -i, -a, -n)
C.  Identify safety and aesthetic considerations:
  • NEC Ratings
  • Fire Codes
  • OSHA
  • MSHA
  • Site specific hazard awareness
D.  Assess existing network infrastructure
E.  Understand logistical considerations (resources, time, access, deployment requirements, etc.)
F.  Comprehend 802.11n impact.
II. Plan for the Site Survey
A.  Select proper survey model:
  • Data
  • Voice
  • Video
  • Location Bridging (Point-to-point; point-to-multipoint)
B.  Determine proper deployment characteristics:
  • Dense deployment
  • Highly mobile (Many cells; high-reliability; fast-moving clients) vs. nomadic (temporary position)
  • Internal meshing
  • Predictive vs. actual
C.  Specify the tools to complete the survey:
  • Obtain digital floor plans from customer
D.  Demonstrate understanding of material attenuation
E.  Define survey documentation deliverables
III. Conduct the Site Survey

  • Use proper radio, power, and data rate
  • User proper client
IV. Design the RF Network
A.  Determine infrastructure requirements:
  • Power
  • Understand cableplant considerations
  • PoE
  • Mounting considerations (NEMA)
  • Outdoor grounding and lightning protection
  • Rack capacity
  • Switch port capacity
  • Consider placement of additional APs for monitorying and sniffing
B.  Determine the AP count and subsequent controller and licenses requirements
C.  Generate the survey documentation
V.  Post Deployment Assessment
A.  Verify RF coverage:
  • Use tools (i.e. AirMagnet) for audit
  • RRM, controller, network appliance tweaks
B.  Verify networks applications and performance:
  • Apply WCS tools (voice readiness, location readiness, site calibration, etc.)
C.  Reconcile actual deployment based on plan
D.  Present installation report to customer
