A predictive wireless design is the first critical step in starting down the road of deploying a successful wireless network. Not only will the predictive design help you avoid problems with your project from the outset but will also ensure you get the most out your new network from day one and potentially avoid spending too much on it.
The challenge however is that not all predictive designs are created equal, and that’s exactly why I want to talk you through what you should expect to receive from a predictive wireless design.
A properly completed predictive design should include at the least the following items:
In order for a proper predictive wireless design to be completed it is necessary that you provide electronic floor plans of your campus, your building or your facilities to the designers. It is also important that the designers gather from you additional information that is critical to the designing process.
The designers will then take these floor plans and the information gathered they have gathered from you and they will import them into a wireless network planning software. The software will take into account the size of the facility, the building materials and how they affect RF, the types of access points and antennas and several other criteria to model a predicted wireless network for you.
Of course, one of the most important pieces of information you will receive from a predictive wireless design is the expected cost of the project. Remember that this is a predictive design, so the project cost should be used as a budgetary estimate. The predictive design should then be used to engage in an active onsite validation survey. The validation survey is another topic for another Blog post but it’s important to keep in mind that the success of a wireless network project is tied directly to the quality of the design. If you implement the predictive design before validating it you run the risk of over engineering or under engineering your project.
You wouldn’t believe how many times we’ve been called in to fix wireless designs that were either under-engineered or over-engineered which in both cases have ended up costing the customer a lot more money.
