Switches, routers, and wireless access points are the essential networking basics. Through them, devices connected to your network can communicate with one another and with other networks, like the Internet. Switches, routers, and wireless access points perform very different functions in a network.
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.
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.
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.
1. Centralized deployment
The most common type of wireless network system, centralized deployments are traditionally used in campuses where buildings and networks are in close proximity. This deployment consolidates the wireless network, which makes upgrades easier and facilitates advanced wireless functionality. Controllers are based on-premises and are installed in a centralized location.
2. Converged deployment
For small campuses or branch offices, converged deployments offer consistency in wireless and wired connections. This deployment converges wired and wireless on one network device—an access switch—and performs the dual role of both switch and wireless controller.
3. Cloud-based deployment
This system uses the cloud to manage network devices deployed on-premises at different locations. The solution requires Cisco Meraki cloud-managed devices, which provide full visibility of the network through their dashboards.
