Enterprises prefer Wi-Fi WLAN in order to enhance work efficiency via mobile office in conventional wireless network solution. Basically, they use wireless AP on the access layer switch and achieve security with WEP encryption or MAC address filtering, user can access wired network via simple authentication. In this structure, user’s data would be forwarded through wireless AP and gateway thus with rather good forward efficiency. However, as business develops, scale of enterprise WLAN grows, networking difficulty, RF interference, security hidden trouble, and equipment and user management become complicated as well.

Conventional WLAN, which is made up of wireless AP (fat AP) + switch, has the following problems: separate configuration on each AP is required; potential network attack and interference can not be checked in the whole system, this reduces the load balance capability; AP can not distinguish the application demands between real time wireless voice and data transmission; security will be in danger if any AP is attacked.

Wireless access controller is a kind of centralized management structure consists of core and simple AP (thin AP), it provides strengthened security, more intelligent wireless broadband management and more efficient wireless security strategy via centralized management, simplified AP and P2P communication, thus helps to break problems in WLAN. In this structure, thin AP takes the place of previous enterprise AP; security, mobility, QoS and other features within the enterprise network can be managed together.

 

 

 

 

 

 

ZDC ZA-5000-WS Series Wireless Access Controller is a series of wireless access controller (AC, Access Controller) researched and developed by Nanjing Z-Com Wireless Co., Ltd. Designed for unified wireless network structure; it has overcome the technical difficulties in networking, RF interference, network security and management. Features high stability, kinds of products, various services and abundant data processes, it integrates RF and user management, security mechanism, seamless roaming, and failure switch together, providing powerful WLAN access control functions.

This series contains integrated type and multi-module rack type, covering from small size network with at least 256 sets of AP to carrier-class large metropolitan area network based on product specification and configuration.

ZA-5000-WS series wireless access controller can be co-used with ZA/ZG-5000-TAP (fat/thin AP) on any existing layer 2 or layer 3 network without configuration on current wired network again. Thanks to this series of products, the administrator can realize management based on wired and wireless fundamental facilities and user application surveillance as well.

ZA-5000-WS	※Enterprise-class integrated structure ※ Carrier-class high reliability ※ N+1 backup ※ Support 512 sets of thin AP at most ※ Designed for middle and large industry park and campus

 

It supports centralized and local forward. Among which, local forward allows user’s data to be forwarded in the local Ethernet port of wireless AP instead of going back to wireless access controller. User can be integrated into wired network as soon as connects to the wireless network, it is a further improvement of the integration of wired and wireless solution. It not only keeps the advantage of centralized control and management, but also allows user’s data to be forwarded based on application classification either via local AP or through wireless access controller.

 

At the beginning of network establishment, fat AP is an ideal choice as the hotspots spread around with fewer users or the equipments are not so many. However, as the development of WLAN, hotspot and user grows, equipment maintenance and network optimization work increases, thin AP is recommended for convenient management and maintenance. ZDC products support switch between fat and thin AP, allowing you to select a best networking according to the scale thus protect your investment. Under fat AP operation, by adding AC, simple switch settings upon AP could be realized via AC or network management system, and centralized control and management upon the whole network can be made.

 

The wireless access controller is able to detect newly accessed AP and make configuration, which relieves users from configuration at site. It realizes plug and play network deployment.

 

ZA-5000-WS Series wireless access controller offers auto FW upgrade, auto configuration distribution and central management upon its thin AP based on advanced centralized intelligent management and control concept. This reduces the investment and difficulty of equipment deployment and maintenance, and it offers plug and play network deployment to users. What’s more, ZA-5000-WS Series wireless access controller supports WEB and SNMP management, allowing administrator to complete equipment configuration and maintenance in the shortest time.

 

It supports complicated balance based on the quantity and flow of accessed users. The wireless access controller will calculate whether there is any AP with fewer loads available around the newly accessed user if it detects the load value on current AP exceeds its threshold. When it finds that AP, it will refuse the connection demand of user and the user will access to that AP then. However, if the wireless client is out of AP overlap coverage, conventional load balance will cause connection failure and wrong balance thereof. ZDC supports auto load balance which ensures only users in AP overlap coverage may have AP load balance; it effectively avoids wrong balance and enhances wireless network capacity to its utmost.

 

RF management enhances the flexibility of wireless network deployment and the ability of network maintenance. ZA-5000-WS Series support auto power adjustment and channel switch which are indispensable in network deployment and debug, simplifying network deployment. Besides, the constant update of RSSI/SNR allows system to know the RF situation every wireless client is in, thus corresponding strategy can be adopted to enhance the network availability.

 

It offers a more secure solution for large network deployment. For example, there are n sets of AC operating individually, and one more as backup AC. If any AC in those “n” group breaks down, that backup one will take its place immediately, and later AP will switch to the primary AC as soon as that primary one gets normal, it ensures that the AP takes primary AC as first choice.

 

1)      Illegal AP Scan

It helps to monitor illegal equipment (e.g. Rouge AP, Ad hoc wireless client), and report to wireless access controller in time for convenient deployment adjustment of thin AP.

 

2)      White List

It ensures only wireless clients in this white list can perform data transmission, others will be taken as illegal users, and their messages will be dropped on AP, thus the attack to wireless network by illegal messages can be avoided.

 

3)      Black List

It ensures that all messages from the devices in this black list will be dropped on AP, thus the attack to wireless network by illegal messages can be avoided.

 

4)      Wireless Broadcast Separation

It prevents malicious attack by wireless client to other clients, and reduces expansion on the wireless network of broadcast messages from this wireless client, thus network performance could be ensured.

 

ZA-5000-WS Series Wireless Access Controller can provide seamless L2/L3 roaming services among different wireless access controllers and network segments, while the IP, security and authentication features in wireless clients won’t change along with the location of wireless clients, and the roaming switch time can fully satisfy the demand of delay-sensitive applications like wireless voice communication and mobile video surveillance.

 

Support kinds of authentication including 802.1x, WPA, WPA2, MAC address filtering, Portal authentication, PPPoE authentication, WAPI, and etc.
