Study Notes
Wireless Access Point Installation
Site Survey
- Conduct a site survey to identify:
- Interference sources (e.g. neighboring WLANs, microwaves)
- Physical obstacles (e.g. walls, ceilings)
- Number of users and devices
- Coverage areas and signal strength requirements
AP Placement
- Place APs in central locations to ensure:
- Maximum coverage area
- Minimum interference
- Optimal signal strength
- Consider AP placement on:
- Ceilings
- Walls
- Columns
AP Power and Connectivity
- Ensure APs are:
- Powered via:
- Power over Ethernet (PoE)
- AC power
- Connected to:
- Switches or routers via Ethernet cables
- Other APs for roaming and redundancy
- Powered via:
Channel Configuration
- Configure APs to operate on:
- Non-overlapping channels (e.g. 1, 6, 11)
- Channels with minimal interference
- Channels that do not overlap with neighboring WLANs
Security Considerations
- Implement:
- WPA2 encryption (or WPA3 for newer devices)
- Authentication mechanisms (e.g. 802.1X, MAC filtering)
- Firewall rules to restrict access and prevent unauthorized connections
Post-Installation Testing
- Verify:
- AP signal strength and coverage area
- Network connectivity and performance
- Security configurations are in place and functioning correctly
Wireless Access Point Installation
Site Survey
- Identify interference sources, including neighboring WLANs and microwaves, to determine potential signal disruptors
- Recognize physical obstacles, such as walls and ceilings, to ensure optimal AP placement
- Determine the number of users and devices to calculate required coverage areas and signal strength
- Measure signal strength requirements to ensure adequate network performance
AP Placement
- Place APs centrally to maximize coverage area and minimize interference
- Consider AP placement on ceilings, walls, and columns for optimal signal distribution
- Ensure APs are positioned to provide stable and reliable connections
AP Power and Connectivity
- Power APs using Power over Ethernet (PoE) or AC power for reliable operation
- Connect APs to switches or routers via Ethernet cables for stable networking
- Connect APs to other APs for roaming and redundancy to ensure continuous coverage
Channel Configuration
- Configure APs to operate on non-overlapping channels (e.g., 1, 6, 11) to minimize interference
- Select channels with minimal interference from other devices and networks
- Avoid channel overlap with neighboring WLANs to maintain network performance
Security Considerations
- Implement WPA2 encryption (or WPA3 for newer devices) to ensure secure data transmission
- Use authentication mechanisms, such as 802.1X and MAC filtering, to control access and prevent unauthorized connections
- Configure firewall rules to restrict access and prevent misuse of network resources
Post-Installation Testing
- Verify AP signal strength and coverage area to ensure adequate network performance
- Test network connectivity and performance to identify potential issues
- Confirm security configurations are in place and functioning correctly to maintain network security
