Wireless Network
Introduction
Computer networks that are not connected by cables are called wireless networks.
Wireless Network
They generally use radio waves for communication between the network nodes. They allow devices to be connected to the network while roaming around within the network coverage.

(PAN) Connects large areas
comprising LANs, MANs and personal networks.
Connects two or more network devices using wireless distribution techniques.
Connect several network devices in small areas (about 30 feet)
Connects two or more
wireless LANs spreading
over a metropolitan area.
WLAN stands for “Wireless Local Area Network“, and it uses the radio waves. There is usually minimum one cable that is defined as access point for accessing internet, like as wired internet connection going into a router, which then broadcasts the wireless signal to other devices. WLAN allows to connect local hardware resources and to the internet. Range of WLAN can be defined about single room to entire campus, office, and home with the using of spread-spectrum or OFDM technologies.

it is used over wide area like as countries and cities through various satellite systems such as cellular service providers or antenna sites. This network allows to users to make phone calls to another connecting via wired or wireless WAN system. With using of wireless WAN, all users are able to make connection with internet to access all websites otherwise others server based applications as well.

WPAN stands for “Wireless Personal Area Network“, and these types of wireless network are used for small areas (about 30 feet) to connect several network devices (Laptop, Desktop, Mobile and more) with using of Bluetooth, Infra Red (IR), and Zigbee technology system.
Bluetooth allows to users to make hand-free call with connecting mobile to earpieces, and it helps to transmit all signals in between all smart devices. Zigbee allows to connect stations along with IoT network. Infrared technique is bound to line of sight like as to make connection in between TV remotes to televisions.

WMAN stands for “Wireless metropolitan area networks”, WMAN allows to connect various different types of WLAN in metropolitan area like as different buildings in a town.
A metropolitan-area network is a computer network that spans across a city, small geographical area, or business or college campus. One feature that differentiates a MAN from a LAN is its size. A LAN usually consists of a solitary building or area. A MAN can cover several square miles, depending on the needs of the organization.
Large companies, for example, may use a MAN if they have a spacious campus and need to manage key components, such as HVAC and electrical systems.

Network (MAN)
What we tend to think of as the end user devices are typically called ‘clients’. As the reach of Wi-Fi has expanded, a variety of devices may be using Wi-Fi to connect the network, including phones, tablets, laptops, desktops, and more. This gives users the ability to move about the area without sacrificing their bridge to the network. In some instances, mobility within an office, warehouse, or other work area is necessary.
Client
Access Point
An access point (AP) consists of a Wi-Fi that is advertising a network name (known as a Service Set Identifier, or SSID). Users who connect to this network will typically find their traffic bridged to a local-area network (LAN) wired network (like Ethernet) for communication to the larger network or even the internet.

How does Wireless Network Work
?
1. It provides clutter-free desks due to the absence of wires and cables.
2. It increases the mobility of network devices connected to the system since the devices need not be connected to each other.
3. Accessing network devices from any location within the network coverage or Wi-Fi hotspot becomes convenient since laying out cables is not needed.
4. Installation and setup of wireless networks are easier.
5. New devices can be easily connected to the existing setup since they needn’t be wired to the present equipment. Also, the number of equipment that can be added or removed to the system can vary considerably since they are not limited by the cable capacity. This makes wireless networks very scalable.
6. Wireless networks require very limited or no wires. Thus, it reduces the equipment and setup costs.
