Types of wifi access points

Enterprise WiFi access points, also called enterprise-grade access points, are wireless network infrastructure devices used to configure wireless communication in business environments. These access points allow Wi-Fi devices to connect to a wired network. Enterprise access points come in various types, which are as follows:

• Controller-based APs

Also known as thin access points, Controller-based APs require a wireless LAN controller to function. The controller manages the access point's configuration parameters and controls its RF management functions. The controller-based APs help ensure consistent performance across the wireless network and are often used in large deployments where centralized management is necessary. However, in the event of a controller failure, the access points may not be able to function properly, which is a downside to consider.

• Standalone APs

Standalone APs are also referred to as autonomous access points. They are typical Wi-Fi access points that operate independently without the need for a wireless LAN controller. Each stand-alone access point must be configured individually, as configuration changes are not automatically synchronized across multiple devices. This can make management more complex, especially in large deployments. However, stand-alone APs are often easier to set up and may be more suitable for smaller networks that do not require extensive centralized management.

• Fat APs

Fat APs, also known as intelligent access points, combine the functions of the controller-based and stand-alone APs. They have some of the centralized intelligence and management capabilities of a controller-based AP but can also operate autonomously if needed. Fat APs offer a hybrid approach, providing the flexibility of working with or without a central controller. This can be useful in environments where both centralized and distributed management are required. However, fat APs may cost more than other types as they offer the features of both.

• Thin APs

Thin APs, also known as lightweight access points, require a central controller to handle configuration and management tasks. The actual intelligence and control of the wireless network reside in the controller, with the thin APs serving primarily as a radio and antenna. This architecture allows for easier deployment and management of multiple access points. However, thin APs may be more expensive because they must be used with a specific wireless LAN controller, which can add to the overall cost of the network infrastructure.

• Scalability

The Cisco access point offers reliable and secure wireless connectivity for a small office, large enterprise, or multi-tenant environment. It allows up to 100,000 client devices to connect to a single mobility domain and up to 40,000 access points.

• High density

This access point prioritizes applications that demand high performance. When many devices connect to the network, it can manage the increased bandwidth and provide uninterrupted services.

• Unified access

With the help of Cisco identity services, this access point provides secure access to the network. It can differentiate between authorized and unauthorized users and block the latter.

• Flexible deployment

It is easy to extend the network to remote locations because this access point can work as a standalone device or a part of a wireless controller. It also works well indoors and outdoors.

• Simple management

It is easy to configure and manage using the Cisco Prime Infrastructure, Cisco DNA Center, or Cisco Mobility Express. Network administrators can optimize the network, detect problems, and troubleshoot them with the management tools.

• Optimized applications

Cisco access points enhance the performance of critical applications by prioritizing them over less important ones. It also provides end-to-end quality of service for voice and video applications.

• Location services

Some models of the Cisco Aironet access point come with built-in Bluetooth Low Energy (BLE) and radio frequency identification (RFID) capabilities. The access points can be used for asset tracking, inventory management, and other location-based services.

• Mesh networking

Cisco Aironet access points work well in harsh environments and extend wireless connectivity to areas where it is difficult to lay cables. It uses intelligent routing to connect to the wired LAN.

• Security

It offers secure and reliable access to network resources. It comes with built-in security features to protect the network from unauthorized access, malware, and other threats. Some access points use WPA3 for encryption and secure Wi-Fi. They also have a firewall, intrusion prevention system (IPS), and VPN support.

Some access points have advanced security features like behavioral analytics. They monitor the network for unusual behavior and block potential threats. The access points regularly update their security features to protect the network from the latest threats. Businesses can also use cloud-based security services to extend protection from the cloud to the access points. The access points use an app to connect to the cloud service and download the security policies. This can be less expensive than using an on-premises security solution.

Q&A

Q1. How far should Cisco Wi-Fi access points be placed from each other?

A1. For seamless Wi-Fi coverage, place the access points within range of each other. The range depends on the access point model. Users can refer to the Cisco wireless LAN design guide for specific distance recommendations.

Q2. Can a Cisco access point be used without a controller?

A2. Yes, a Cisco access point can be used without a controller. This is known as autonomous mode. In this mode, the access point functions as a stand-alone device. It needs to be configured independently. However, this is only feasible when managing a small number of access points. For larger deployments, using a controller is essential for efficient management and configuration consistency across all access points.

Q3. How to add a Cisco access point to a Cisco wireless controller?

A3. To add a Cisco access point to a Cisco wireless controller, start by connecting the access point to the network. Ensure the controller and access point are on the same subnet. Then, power on the access point. It can be adopted using the controller's interface. The controller will automatically detect the new access point. Finally, configure the access point settings on the controller as needed.

Q4. Do Cisco access points have default passwords?

A4. Yes. Cisco access points have default usernames and passwords. They are usually ‘cisco.’ However, users should always change the default password for security reasons. The default password is a common target for hackers.
