Which tool should you choose best for the survey? There are three basic types:
The first is Windows-based software, which can be used on a single laptop. These software help you record estimation calculations such as signal length when walking around the building. You only need to buy a single AP and rotate around the potential locations identified in step 3. This tool is suitable for places that require small installations, only from one to three APs.
They are also good in case you don't have a simple 'open office' plan, but there are different types of corridors and latent wave dead spots scattered around many floors. There are free tools for you to choose from such as NetStumbler and more features with AirMagnet Survey, Visiwave, Fluke Networks InterpretAir, Ekahau Site Survey, but costing a few thousand dollars.
There are also other tools that work in conjunction with switching wireless products. They can be from Cisco Systems, Aruba Networks and Trapeze Networks, monitoring your wave range, giving you location advice on where to place the best AP points.
The Aruba Mobility Controller has a free trial period and is an integral part of the manufacturer's switch set. Cisco's Wireless Control System costs $ 4,000 and Trapeze's RingMaster costs more than $ 549. If you have not decided on a wireless infrastructure vendor, rate their analysis tool.

Depending on the base plan and the number of obstacles such as thick walls and metal walls, you may need to purchase one of the "wall-around" tools discussed above.
Finally there are some similar tools with great elasticity. They are useful in assessing sizes for places of multi-storey construction, yard grounds, campuses. You can also use for similar deployment activities or for the requirements of many different models in the future. These tools include SpectraGuard Planner of AirTight Networks, Wireless Valley LANPlanner, AirDefense Survey of Motorola, Bluesocket's Wireless LAN Planner. Trapeze's RingMaster is also capable of building radio models and similar functions. These tools are useful in evaluating the total number of APs you will need and simulating the final environment to build for you relatively well. But they can't tell you which devices are obstructing or give you an overall overview of the wireless network environment you're about to build.
Remember, conducting a wireless network survey is never enough. They need to be done periodically. The wave environment may change when Bluetooth keyboards and radio listening devices come and go, as well as when microwave ovens turn on / off, or when a variety of other wireless devices contaminate the allocation sequence. 802.11 standard.
So first listen to users who will surely complain that their signals are too weak and look for new dead spots in your building. And make sure that surveys are a part of network activities in general.
