The Cisco 5520 Wireless Controller provides centralized control, management, and troubleshooting for high-scale deployments in service provider and large campus deployments. It offers flexibility to support multiple deployment modes in the same controller: for example, centralized mode for campus, Cisco FlexConnect™ mode for lean branches managed over the WAN, and mesh (bridge) mode for deployments where full Ethernet cabling is unavailable. As a component of the Cisco Unified Wireless Network, this controller provides real-time communications between Cisco Aironet® access points, the Cisco Prime™ Infrastructure, and the Cisco Mobility Services Engine, and is interoperable with other Cisco controllers. | |

About Cisco
Cisco's approach to quality can be condensed down to one phrase: "ensuring our customer success". The information contained in this section will help you to gain a better understanding of Cisco's Business Management System, which allows us to accomplish that success. Cisco's Business Management System is made up of two parts; the Quality Management System and the Environmental Management System.
Cisco Fun Facts
Cisco Systems, Inc. is an American multinational technology conglomerate headquartered in San Jose, California, in the center of Silicon Valley, that develops, manufactures and sells networking hardware, telecommunications equipment and other high-technology services and products. Through its numerous acquired subsidiaries, such as OpenDNS, WebEx, Jabber and Jasper, Cisco specializes into specific tech markets, such as Internet of Things (IoT), domain security and energy management.
Cisco is the largest networking company in the world. The stock was added to the Dow Jones Industrial Average on June 8, 2009, and is also included in the S&P 500 Index, the Russell 1000 Index, NASDAQ-100 Index and the Russell 1000 Growth Stock Index.
Cisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists, who pioneered the concept of a local area network (LAN) being used to connect geographically disparate computers over a multiprotocol router system. By the time the company went public in 1990, when it was listed on the NASDAQ, Cisco had a market capitalization of $224 million. Cisco was the most valuable company in the world by 2000, with a more than $500 billion market capitalization

Learn more about Wireless Access Points
Switches, routers, and wireless access points
Switches, routers, and wireless access points perform very different functions in a network.
A computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections (data links) between nodes These data links are established over cable media such as wires or optic cables, or wireless media such as WiFi.Switches
Switches are the foundation of most business networks. A switch acts as a controller, connecting computers, printers, and servers to a network in a building or a campus.
Switches allow devices on your network to communicate with each other, as well as with other networks, creating a network of shared resources. Through information sharing and resource allocation, switches save money and increase productivity.
There are two basic types of switches to choose from as part of your networking basics: managed and unmanaged.
- An unmanaged switch works out of the box but can't be configured. Home-networking equipment typically offers unmanaged switches.
- A managed switch can be configured. You can monitor and adjust a managed switch locally or remotely, giving you greater control over network traffic and access.
Routers
Routers connect multiple networks together. They also connect computers on those networks to the Internet. Routers enable all networked computers to share a single Internet connection, which saves money.
A router acts a dispatcher. It analyzes data being sent across a network, chooses the best route for data to travel, and sends it on its way.
Routers connect your business to the world, protect information from security threats, and can even decide which computers receive priority over others.
Beyond those basic networking functions, routers come with additional features to make networking easier or more secure. Depending on your needs, for example, you can choose a router with a firewall, a virtual private network (VPN), or an Internet Protocol (IP) communications system.
Access points
An access point* allows devices to connect to the wireless network without cables. A wireless network makes it easy to bring new devices online and provides flexible support to mobile workers.
An access point acts like an amplifier for your network. While a router provides the bandwidth, an access point extends that bandwidth so that the network can support many devices, and those devices can access the network from farther away.
But an access point does more than simply extend Wi-Fi. It can also give useful data about the devices on the network, provide proactive security, and serve many other practical purposes.
*Access points support different IEEE standards. Each standard is an amendment that was ratified over time. The standards operate on varying frequencies, deliver different bandwidth, and support different numbers of channels.
Wireless networking
Wireless networking is a method by which homes, telecommunications networks and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.CompSource will educate and help make this process enjoyable and easy.
