What is Wireless Network
Definition: If, Computer network do not need any types of cable for making connection in between multiple network nodes like as laptop, PC, phone, and more. So, it is known as “Wireless Network”, because, they mostly makes use of Radio Frequency (RF) connections between nodes in the network.
Wireless networks are best option for different areas like as homes, businesses, and telecommunications networks. Wireless network allows to users get freedom to move about specific range while connecting wireless devices.
Diagram of Wireless Network
Wireless networking is more cheapest and affordable method to set up an Internet network system, because there are not use any cable, so all family members can free to use their devices any area in the house, as well as other devices can be connected over the network in few seconds.
Types of Wireless Network
There are different types of wireless network; below explain each one.
- Wireless WAN
- Wireless PAN
- Wireless LAN
- Wireless MAN
- Global Area Network
- Space Network
- Wireless Ad Hoc Network
Comparison of Wireless Network Types
Wireless WAN: WWAN stands for “Wireless Wide Area Network“, and 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.
Wireless PAN: 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.
Wireless LAN: 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.
Wireless MAN: 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.
Global Area Network: Global area network is used for getting to support mobile phone across a arbitrary number of wireless LANs, satellite coverage areas, and more.
Space Network: This network is used for making the communication in between the spacecraft, usually in the vicinity of the Earth. For example is NASA’s Space Network.
Wireless Ad Hoc Network: A wireless ad hoc network is also called the “Mobile Ad Hoc Network (MANET)”, and this wireless network built up with radio organized in a mesh topology.
Examples of Wireless Network
- Cordless Phones
- Radio Frequency Identification (RFID)
- Cell phone networks (Cellular Communication)
- Wireless sensor networks
- Satellite communication networks
- Terrestrial microwave networks
- Television and Radio Broadcasting
- Satellite Communication
- AM radio
- FM radio
- HD Radio,
- SiriusXM satellite radio
Types of Wireless Network Devices
There are different types of network devices which are used in the wireless network; below explain each one.
Wireless Adapters: Wireless adapters are embedded into computer’s motherboard which help to make wireless connectivity, because without using of wireless adapter, it can’t able to connect with router for getting to access the Internet.
Wireless Repeater: Wireless repeaters are used to scale the range of router. Repeater obtains the wireless signals and re-emits those signals along with strength. The repeater is placed in between the PC and router for connecting to router, and its result is too boosted up signal strength, so internet’s speed is getting to faster.
Wireless Router: Wireless router is a networking hardware device that allows grabbing incoming internet connection and broadcasting data in the form of RF signals to other networks wireless devices which are around the wireless router. Wireless routers help to make connection with wireless enable PCs as well as other devices to internet. Several routers consist the security features like as firewall that allows to protection against viruses and malicious data.
Wireless Phones: Cellular and cordless phones are getting to work with wireless signals. Mobile phones have wider range, but cordless phones have just few meters of range. Mobile phone companies provide the much larger coverage with using of their telecommunication towers.
