What is a site survey, many types??

1. Active (dependent on site readiness) time consuming

2. Predictive (planning tool) very time consuming

3. Active (repeat on live network) less time consuming

Goals

Fulfil coverage/capacity applications requirement

exact AP location (wiring)

exact AP count

exact antenna.

Role of site survey, is as important as ever

Evaluate the existing application requirements, available spectrum and client types/mix

Focus on fixed infrastructure

– AP placement

– Density is important = capacity

– Protocols supported

– Rates supported

Sites-surveys, for “capacity” not just “coverage”

Rely on professional tools to monitor, troubleshoot

A device on the network is far less damaging than a device off the network!

Quick win features

– Disable lower data rates

– Use more bandwidth, >20 Mhz channel width

– BandSelect “direct client to 5 Ghz”

– WLC Configuration Analyzer

– Match outcome to expectations

– Bring visibility to upper management
