Scalability: Adding access points to a network is a scalable way to accommodate an increasing number of wireless devices. As your network grows, you can simply deploy additional access points to maintain optimal connectivity.
Roaming Support: Access points can facilitate seamless device roaming within a network. When a device moves from one area covered by one access point to another, it can automatically switch to the access point with the strongest signal without losing connectivity.
Security: Access points can be configured with security features such as encryption (WPA2/WPA3), MAC address filtering, and guest network isolation. These features help protect the network from unauthorized access and data breaches.
Guest Networks: Many access points support the creation of guest networks. These isolated networks allow visitors to connect to the internet without gaining access to the main network, enhancing security for your internal devices.
Centralized Management: In larger deployments, multiple access points can be managed centrally through a controller or management software. This simplifies the administration of the entire wireless network, making it easier to monitor and configure access points.
Quality of Service (QoS): Access points can prioritize certain types of network traffic over others, ensuring that critical applications (e.g., video conferencing or VoIP calls) receive the necessary bandwidth and low latency for optimal performance.
Mesh Networking: Some modern access points support mesh networking, where access points work together to create a self-healing network. If one access point fails, the others can automatically reroute traffic to maintain network connectivity.
Fast and Easy Deployment: Setting up access points is generally straightforward. Many access points have user-friendly interfaces, and some can be powered through Power over Ethernet (PoE), simplifying installation.
Cost-Effective: Access points are a cost-effective way to provide wireless connectivity to a network, especially in situations where running Ethernet cables to every device is not practical or cost-prohibitive.
Common types of Access Points
Standalone Access Points: These are single devices that provide wireless connectivity to a wired network. Standalone access points are typically used in smaller environments or when you need to add wireless capabilities to an existing wired network. They are configured individually and do not require a central controller.
