Improved Reliability
Improved Reliability
Having multiple BSSs running on different channels in a wireless network adds robustness as it enables communication even if one BSS is unavailable due to interference or failure.
Reduced Congestion
Reduced Congestion
Distributing devices across different BSSs within a wireless network minimizes resource contention, as devices are competing for resources within their own BSS, not the whole network.
Better Security
Better Security
Each BSS can have its own security measures, granting controlled access and enhancing network protection.

Study Notes
Introduction to Basic Service Set (BSS)
- A Basic Service Set (BSS) is the fundamental building block of a wireless local area network (WLAN).
- It's a group of wireless stations (clients) that communicate with a single access point (AP).
- The AP acts as a central hub, coordinating communication between all stations within the BSS.
Key Characteristics of a BSS
- Single Access Point (AP): A BSS is defined by a single access point, which broadcasts a unique Service Set Identifier (SSID) to identify the BSS and attract clients.
- Direct Communication: Stations within a BSS can communicate directly with each other.
- Coexistence: Multiple BSSs can potentially coexist, however, overlapping channels can lead to interference.
- Limited Range: The range of a BSS is usually limited, depending on the power of the AP and the environment.
- Infrastructure Mode: A BSS operates in infrastructure mode, relying on the AP for connectivity and management.
Components of a BSS
- Access Point (AP): Serves as the central point for communication within the BSS, connecting wireless stations to the wired network.
- Wireless Stations (Clients): Devices with wireless network capability that join the BSS to communicate.
- Network Interface Cards (NICs): Hardware components on the clients that enable wireless communication.
BSS Operation
- Association: A device attempts to connect to a BSS identified by its SSID.
- Authentication: The AP verifies the device's credentials.
- Association Completion: After authentication, the device joins the BSS and becomes associated.
- Data Transmission: Data is transmitted between stations within the BSS through the AP facilitating communication.
Types of BSS Configurations
- Independent Basic Service Set (IBSS): An ad-hoc network where stations communicate directly without an AP; there's no central control.
- Infrastructure Basic Service Set (BSS): A network with an AP handling the coordination of communication among stations.
Differences between IBSS and BSS
| Feature | IBSS | BSS |
|---|---|---|
| Access Point | No | Yes |
| Centralized coordination | No | Yes |
| Structure | Ad-hoc | Infrastructure |
| Scalability | Limited | High |
| Reliability | Lower | Higher |
Significance of a BSS in a Larger Network
- Network Segmentation: Separating devices into manageable BSSs enhances network security and improves performance.
- Improved Reliability: Multiple BSSs, using different channels, can create redundancy to cope with interference and network outages.
- Reduced Congestion: Separating devices into different BSSs prevents resource contention that can compromise network performance.
- Better Security: Access to resources can be controlled and access point security measures can be implemented at a BSS level.
Considerations for BSS Design
- Channel Selection: Choosing the appropriate channel to avoid interference with other networks.
- Power Control: The AP adjusts its output power to optimize range and prevent interference from neighbouring networks.
- Security Measures: Implementing security measures, such as WPA2/3 encryption, to protect network traffic.
- SSID Broadcasting: Strategically utilizing SSID settings for better security against unauthorized connections.
