What is a wireless LAN controller?
WLAN controller, a centralized Wi-Fi management device that manages all the wireless access points (APs) in an enterprise network. Particularly for some large campus networks, the wireless access controller (AC) is indispensable on account of the following prominent advantages: flexibility in deployment & expansion, simplicity in operation & management, high reliability & security for a seamless & safe wireless network, etc.
Nodexon NX-SG3750 wireless controller has the ability to manage up to 224 wireless access points, MAX. 7,168 clients, achieving integrated access for wired and wireless users. This centralized wireless LAN controller is especially fit for high-density environments. As a future-proofing solution, adopting Nodexon wireless LAN controller is also convenient for future network expansions or upgrades.
However, does more available APs indicate more complex management? Simplified web management that Nodexon NX-SG3750 wireless LAN controller solution offers will eliminate your concerns. Nodexon NX-SG3750 wireless controller web management interface is intuitive and user-friendly for wireless configuration and network operation. The easy-to-use dashboard makes it convenient to see your real-time network status; check network usage and traffic distribution; receive network condition logs, notifications, and abnormal event warnings. The IT admins can quickly see and troubleshoot connections at a glance with this web management. Furthermore, Nodexon NX-SG3750 also provides centralized management of remote access points via this simple interface, allowing administrators to manage Wi-Fi 6 APs and the associated users with great convenience.
Nodexon NX-SG3750 high-performance wireless LAN controller ensures high-reliable wireless network connectivity via various functions. From the perspective of hardware, the virtual AC technology allows virtualizing multiple AC into a single logical AC in a single high availability cluster. Therefore, there will be no business downtime in the event one of the AC fails. Possessing a fully automated failover mechanism with milliseconds' completion, the Wi-Fi services will resume immediately in backup AC. From the perspective of software, it supports real-time synchronization of online info and roaming records of all users among multiple wireless controllers. That is to say, the user and authentication data are shared in the cluster, enabling wireless users to roam freely in the whole network.
Furthermore, a series of sophisticated protocols are adopted by the Nodexon NX-SG3750 wireless LAN controller to protect your wireless network's security. On the one hand, it fully supports advanced encryption technologies such as Wired Equivalent Privacy (WEP), Temporal Key Integrity Protocol (TKIP), and Advanced Encryption Standard (AES) for end-to-end security of data transmission. On the other hand, a wide range of built-in security mechanisms effectively prevent and control virus spread and network traffic attacks, covering IP/MAC/WLAN binding, hardware ACL control, traffic-based bandwidth limitation, etc.
On a high-density wireless LAN, Nodexon NX-SG3750 wireless controller can intelligently distribute users among different APs according to the number of users and data traffic in real-time. This intelligent load balancing feature balances the load pressure on each AP and improves the average bandwidth and Quality of Service (QoS), offering higher network availability, and ultimately, optimizing users' experience.
In a WLAN networking scenario, there are typically two deployment ways. The first method is to connect wireless AC to wireless APs or to access switches. In this case, the wireless AC handles all the business, functioning as AC and aggregation switch at the same time. This networking structure is clear and simple to implement. Another option is to "add" a wireless LAN controller into the current network, namely, connecting it to the aggregation switch to realize centralized WLAN management. In this case, the wireless AC doesn't connect to the APs directly. Therefore, this kind of networking method is beneficial for network expansions, which has been widely applied in most networking scenarios.
Nodexon NX-SG3750 wireless LAN controller solution just adopts the second networking deployment method, and can be deployed at layer 2 or layer 3 without modifying the original network architecture. Forming an integrated switching framework with the APs, the controllers handle all the AP data exchange management with ease. The NX-SG3750 wireless controller can be applied for campus networks, enterprise office networks, wireless Metropolitan Area Networks (MANs), and hotspot coverage networks, etc.
