There are two primary types of access points (APs) used in networking:
- Wired Access Points: These APs are connected to the network via Ethernet cables and provide wireless connectivity to devices within their coverage area. They typically integrate with existing wired networks to extend network access wirelessly.
- Wireless Access Points: These APs operate wirelessly and serve as the central hub for connecting wireless devices to a wired network. They transmit and receive wireless signals, allowing devices like laptops, smartphones, and tablets to access network resources without requiring physical connections.
Access points (APs) are devices in computer networking that enable wireless devices to connect to a wired network. They come in different types based on their deployment and functionality:
- Stand-alone Access Points: These are individual AP devices that operate independently and are typically used in smaller deployments or where only basic wireless connectivity is required.
- Controller-based Access Points: These APs are managed and controlled by a central wireless LAN controller (WLC). The controller coordinates and optimizes the operation of multiple APs within a network, providing centralized management and configuration.
Access lists (ACLs) in networking typically refer to two main types:
- Standard Access Lists: These ACLs filter traffic based solely on source IP addresses. They are less flexible but simpler to configure, making them suitable for basic network access control needs.
- Extended Access Lists: These ACLs filter traffic based on source and destination IP addresses, protocols, port numbers, and other parameters. They offer more granular control over network traffic but require more configuration effort.
The two primary functions of an access point (AP) in a wireless network are:
- Wireless Connectivity: APs provide wireless connectivity to devices within their coverage area, enabling them to access network resources such as the internet, file servers, and other devices on the network.
- Security and Authentication: APs enforce security measures such as encryption (e.g., WPA2) and authentication (e.g., WPA-Enterprise) to protect wireless communications and ensure that only authorized devices can connect to the network.
Different types of access points can be named based on their specific features or intended use cases:
- Outdoor Access Points: Designed for outdoor environments, these APs are ruggedized and weatherproof to withstand outdoor conditions while providing wireless coverage.
- Indoor Access Points: These APs are optimized for indoor use, providing reliable wireless connectivity within buildings and facilities.
- Mesh Access Points: Mesh APs form a mesh network by wirelessly connecting to each other, extending network coverage without the need for wired connections to each AP.
- Enterprise Access Points: These APs are designed for deployment in large-scale enterprise networks, offering advanced features like high performance, scalability, and centralized management.
- Consumer Access Points: APs targeted for home or small office environments, typically providing basic wireless connectivity features in an easy-to-use package.
