A wireless local-area network (LAN) employs radio waves to connect devices like laptops and mobile phones to the Internet, the business network, and its applicability. The first professional wireless network was formed under the brand ALOHAnet in 1969 at the University of Hawaii and matured to become operational in June 1971. The first commercial wireless network was the WaveLAN product family, developed by NCR in 1986.

Wireless Network Vs. Wired Network
A wireless network enables devices to stay connected to the network but roams untethered to any cables. Access points magnify Wi-Fi signals, so a tool can be considerably from a router but still be connected to the network. For example, when you attach to a Wi-Fi hotspot at a cafe, an airport lounge, a hotel, or a different public place, you’re linking to that business’s wireless network.
A wired network employs cables to connect devices, like laptop or desktop computers, to the Internet or a different network. A wired network has a few limitations when compared to a wireless network. The most significant drawback is that your device is fastened to a router. The most common wired networks utilize cables connected at one end to an Ethernet port on the network router and the other terminal to a computer or other device.
Earlier it was considered that wired networks were faster and more reliable than wireless networks. But persistent augmentations to wireless network technology like the Wi-Fi 6 networking standard have eroded pace and security differences between wired and wireless networks.
A mobile network or cellular network is a radio network distributed over land areas termed cells. Each is followed by at least one fixed-location transceiver, identified as a cell site or base station. Each cell characteristically uses a different set of radio frequencies from all their immediate neighbouring cells to avoid any interference in a cellular network.
When joined unitedly, these cells contribute radio coverage over a wide geographic area. In addition, it enables many portable transceivers (e.g., mobile phones, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations, even if some of the transceivers are moving through more than one cell during transmission.
Benefits of Wireless Network
Businesses can encounter many advantages from a Cisco wireless network, including:
- Easy setup: You don’t hold to string cables so that installation can be swift and cost-effective.
- Expandability: You can immediately expand wireless networks with current equipment, whereas a wired network might need additional wiring.
- Security: Progress in wireless networks provides robust security protections.
- Convenience: Access your network devices from any location within the wireless network’s coverage range or any Wi-Fi hotspot.
- Reduced cost: Because wireless networks exclude or reduce wiring expenses, they can get less to run than wired networks.
- Mobility: You’re not bound to your desk, as you are with a wired connection. For example, you and your co-workers can operate online to conference room meetings.
- Productivity: Wireless admittance to the Internet and your company’s critical applications and resources helps your staff get the job done and encourages collaboration.
Deploying a Wireless Network
You can choose between three deployment types to create your wireless network: centralized deployment converged deployment and cloud-based deployment. Want guidance deciding on which deployment is most suitable for your business? Here’s the difference.
1. Centralized Deployment: The most popular type of wireless network system, centralized deployments, are conventionally used in campuses where structures and networks are nearby. This deployment unites the wireless network, which offers upgrades more accessible and encourages advanced wireless functionality. Controllers are based on-premises and are established in a centralized spot.
2. Converged Deployment: For tiny campuses or branch offices, concentrated deployments offer consistency in wireless and wired connections. This deployment connects wired and wireless on one network device—an access switch—and delivers the dual role of both regulator and wireless controller.
3. Cloud-Based Deployment: This system uses the cloud to handle network devices deployed on-premises at various locations. The solution may need cloud-managed devices, which give complete visibility of the network within their dashboards.
