Why is a Wireless Site Survey much Needed? from BROCENT ASIA's blog

A Wireless Site Survey is suggested when implementing a wireless network. For large wireless network placements, a site survey is a must-have element. For small wireless deployments, a site survey is better to have but sometimes the cost becomes an issue. When deploying a wireless system, we are looking for the best wireless coverage with minimal use of equipment. This saves much time, manpower, and also equipment cost. To get the best Wireless Site Survey and performance, we need to understand the Radio Frequency behaviour of our wireless network site.

 A wireless site survey will provide this data by revealing places of signal intrusions, places where signals are weak, and areas of no signals. A wireless survey also supports avoiding interference due to prevailing radio sources and interventions caused by physical structures. Anything can affect the radio signal outline of a site including furniture and individuals. It is significant to remember that a wireless site survey aims to control the feasibility of deploying a wireless system to meet your requirements and to determine how to deploy a network in the constraints of your site.

How will a Wireless Site Survey help you?

When deploying a wireless network, access points are placed at random. In small deployments, the approach is not a problem but with average, to large deployments, a wireless site survey is counseled and often needed. A wireless site survey helps to control where to place APs to avoid intrusion and avoid overlap coverage. In preparation, many network managers randomly place APs and install extra WiFi APs when coverage is needed or when they get grievances about bad access. In an ad-hoc network, the network manager has no idea what type of interference exists and how the site’s signal profile changes. Getting a wireless site survey, will help determine if there are interferences and how much external radio interferences are producing problems.
