Starting with site surveys is key to a good wireless setup. These surveys look at the physical space to find the best places for access points. They check the building materials and any obstacles to the signal.
Today’s surveys use heat mapping software to show how signals spread. This tool helps spot areas with no signal or where more coverage is needed. A good survey ensures everyone stays connected.
When assessing a site, consider:
- What walls are made of and how signals pass through
- The electrical setup and power options
- Any sources of interference
- How many people will be using the network and how they move
Capacity Planning and Channel Management
Planning for network capacity is vital to avoid slowdowns. Experts say each access point should handle 10-25 devices. But, the real limit depends on the environment and how people use it.
When deciding how many devices can connect, think about what they’re doing online. Streaming videos, for example, needs more careful planning. How fast you need the network affects how many access points you need.
Managing channels well helps avoid interference. Access points usually use different frequencies to keep signals clear. This keeps the network running smoothly.
Today’s systems can pick the best channel for you. They watch the radio environment and change channels as needed. This keeps your network running at its best.
| Planning Factor | Consideration | Optimal Range | Impact on Performance |
|---|---|---|---|
| Client Density | Number of devices per AP | 10-25 devices | Higher density reduces individual throughput |
| Channel Selection | Frequency assignment | Non-overlapping channels | Prevents interference between adjacent APs |
| Signal Strength | Coverage area per AP | -67 dBm minimum | Affects connection stability and speed |
| Bandwidth Requirements | Application needs | Variable by use case | Determines overall network capacity needs |
It’s important to document all your decisions when setting up. This helps with future changes or problems. Keeping an eye on how the network is doing ensures it meets everyone’s needs.
