External and Internal Registration

It is not necessary for the WAP devices to handle the registration of clients on the network themselves. The WAP device can either use its built-in registrar, or act as a proxy for an external registrar. The external registrar may be accessed through the wired or wireless LAN. An external registrar may also configure the SSID, encryption mode, and public shared key of a WPS-enabled BSS. This capability is very useful for out-of-box deployments; that is, when an administrator simply attaches a new WAP device to a LAN for the first time.

If the WAP device is using a built-in registrar, it enrolls new clients using the configuration of the VAP associated with the WPS service, whether this configuration was configured directly on the WAP device or acquired by an external registrar through WPS.

Client Enrollment

Push-button Control

The WAP device enrolls 802.11 clients through WPS by one of two methods: the Push-Button Control (PBC) method, or the Personal Identification Number (PIN) method.

The PBC method is when the user of a prospective client pushes a button on the enrolling device, and the administrator of the WAP device with an enabled built-in registrar pushes a similar (hardware or software) button. This sequence begins the enrollment process, and the client device joins the network. Although the Cisco WAP devices do not support an actual hardware button, the administrator can initiate the enrollment for a particular VAP using a software button in the web- based configuration utility.

NOTE There is no defined order in which the buttons on the client device and WAP device must be pressed. Either device can initiate the enrollment. However, if the software button on the WAP device is pressed, and no client attempts to enroll after 120 seconds, the WAP device terminates the pending WPS enrollment transaction.

PIN Control

A client may also enroll with a registrar by using a PIN. For example, the WAP device administrator may start an enrollment transaction for a particular VAP by entering the PIN of a client. When the client detects the WPS-enabled device, the user can then supply its PIN to the WAP device to continue the enrollment process. After the WPS protocol has completed, the client securely joins the network. The client can also initiate this process.

WAP121, WAP321 specifications

Cisco Systems has long been recognized for its innovation in networking technologies, and the Cisco WAP321 and WAP121 access points are prime examples of its commitment to delivering reliable, high-performance wireless networking solutions for small and medium-sized businesses. These devices offer a robust set of features designed to meet the requirements of modern wireless networking while ensuring ease of use and deployment.

The Cisco WAP321 is a dual-band access point that operates in both the 2.4 GHz and 5 GHz frequency bands, providing flexibility and improved performance in crowded environments. With support for the 802.11n Wi-Fi standard, it boasts a combined data rate of up to 450 Mbps, enabling high-speed connections for multiple users simultaneously. The WAP321 also includes advanced features such as multiple SSIDs and VLAN support, allowing businesses to segment their networks for enhanced security and management control.

One of the standout characteristics of the WAP321 is its ability to act as a lightweight access point, meaning it can be managed through a Cisco Wireless LAN Controller (WLC) for larger deployments. This capability allows for centralized management of multiple access points, making it easier for IT administrators to deploy, configure, and monitor their network infrastructure.

On the other hand, the Cisco WAP121 is designed for those requiring a simpler, more cost-effective solution. This single-band access point also operates on the 2.4 GHz band but still provides robust performance with wireless speeds reaching up to 300 Mbps. It is ideal for small businesses looking to develop or expand their wireless networks without the complexities associated with more advanced systems.

Both models feature Power over Ethernet (PoE) capability, enabling them to receive power through the Ethernet cable, which simplifies installation and reduces the need for additional power outlets. Additionally, they support advanced security protocols, including WPA/WPA2 encryption, ensuring that sensitive data transmitted over the network remains protected from unauthorized access.

The ease of setup and user-friendly management interfaces of both the WAP321 and WAP121 make them appealing options for businesses lacking extensive IT resources. With features aimed at enhancing both performance and security, these access points represent powerful tools for achieving reliable wireless connectivity in a business environment. Whether organizations opt for the WAP321 for its extensive capabilities or the WAP121 for its simplicity, both access points reflect Cisco's dedication to meeting diverse networking needs.
