Benefits of Wireless Site Assessments
RF signals are very unpredictable. If an access point is placed in an open environment without obstacles, the signals usually maintain an omni-directional pattern. However, when obstacles and walls are introduced, the RF signals are disrupted and access point coverage varies based on location.Site surveys determine signal coverage, throughput requirements, interfering sources, dead spots, potential roaming behavior, etc. and helps determine:
Without site surveys it is difficult to determine the capital investment needed to deploy the wireless network in a timely and cost efficient manner.
It is important not to generalize every wireless deployment in terms of requirements. For example, in an office environment where file and print services and Internet access are the primary needs, a few dead spots may be tolerable. But in a healthcare environment where medical personnel require unrestricted wireless access to patient information this is unacceptable. Without site surveys it would be virtually impossible to determine if the technical requirements of the business can be supported.
