Site Surveys
Site surveys are used to measure the wireless characteristics of the physical environment and
thereby determine cost-efficient placement of equipment in the network. They are important
because the physical attributes of a location may have a significant impact on realized coverage and
data rates. The site survey involves a detailed assessment of the radio signal environment of the site
based on experiments and testing. After the wireless network equipment is installed, radio signals
are sent between the AP and a mobile client (laptop) to effectively tune the placement of APs.
A professional site survey is highly recommended for large installations, but can be an expensive
and time-consuming process, especially for installations with a variety of buildings and building
materials, radio signal conditions, and restrictions on equipment placement. Thanks to the dramatic
improvements in capacity and coverage provided by Airgo APs, many small to mid-size companies
can forgo the traditional site survey process and rely instead on general guidelines.
Assessing Security Needs and Architecture
The latest security innovations and standards make it possible to provide complete and effective
security for wireless networks. The specifics of an optimal security solution will vary according to
the type and size of organization. For each environment, Airgo offers a selection of features to
satisfy all your security needs.
Three aspects of security require planning and decisions:
• Enrollment—Specifying the Airgo AP or NMS Pro server used to verify which access points
are authorized to be part of the wireless network.
