After you have a firm set of requirements, focus on design. This determines how you're going to satisfy requirements with least cost. The design should fully describe what components and configurations are necessary to satisfy the requirements.

Through the design process, produce a design specification that highlights the chosen design elements and provides a diagram indicating the placement of access points within the facility. For smaller networks, you may only spend a day or so designing the solution. In larger implementations, it may take weeks or months to fully define enough technical detail before moving forward with the acquisition of hardware and installation services. These larger projects will likely benefit from simulation, prototyping, or pilot testing as part of the design to ensure you've made the right choices and the requirements are fully realizable.
