4.3. Post Install Survey

Wireless networks are often changing to meet new application demands, business processes, or in
response to external influences (neighboring networks and other spectrum disturbing sources.) For this
reason, Alcatel-Lucent recommends regular radio coverage surveys in order to continuously revalidate
system operation. This is not a mandatory process, but a recommended one as proactive network
modification is often less costly and disruptive than reactionary engineering to sudden holes or
degradations in the RF coverage plan.
The regularity by which a customer should consider RF coverage re-evaluation depends greatly on
network size, radio spectrum competition, sensitivity to degraded voice quality, rate of user population
growth, and other factors. As a general rule, Alcatel-Lucent recommends re-evaluation whenever new
technology demand is generated or roughly every 18 months. Some customers may be able to happily
use VoWLAN technology in a static environment for many years without a renewed survey, others may
find that continuous evolution of network demands require a validation every six months. It is
recommended to set proper customer expectations before they decide to implement VoWLAN
technology.
