Examples Of Personal Area Network
Types Of Wireless Networks
A Wireless Network combines two or more computer without using any wires bymeans of communication. Wireless Networks uses spread-spectrum or depends onOFDM technology.> It enables a user to move within a wide coverage area but still connected to> the network.Wireless networks are classified into different type such as wireless LAN,WAN, MAN, PAN, Hybrid, Ad-Hoc networks.
WLAN (Wireless Local Area Network)
WLAN is delivering highest data-transfer rate with 802.11 terminologies.Wireless Area Network uses radio signal instead of traditional network cablingand built by a device called AP. WLAN has well-built status in a differentkind of markets and set up to provide wireless connectivity within a limitedexposure area such as a hospital, airport, a university, gas plant, or healthcare providers.WLAN is delivering highest data-transfer rate with 802.11 terminologies.The technology used in WLAN is Frequency-hopping spread-spectrum whichmaintains a single logical channel. The Direct-Sequence Spread Spectrum giveschip pattern to make it more efficient and infrared technology.The benefits of local area networks are high range and coverage, integrity,Interoperability with wired and wireless infrastructure, Interference,Simplicity, Ease, Security, Cost, Scalability and safety which makes a greatplatform for the wireless network.
WWAN (Wireless Wide Area Network)
Wide Area Network is a communication network that extends over a largedistance or place. They connect different smaller networks, such as local areanetwork and metropolitan area network.> In an enterprise, WAN can be used for a company’s headquarters, cloud> services, branch office, and other facilities.WANs do not link individual computer but it is used to link LANs.
WPAN (Wireless Personal Area Network)
Wireless Personal Area Networks are short-range networks that are used tointerconnect the devices based on Bluetooth technology in a central locationlike a desk. The range of personal area network is about 30 feet.> The IEEE standard of WPAN is 802.15 and it is suitable for individual> workspace.This provides data transmission for devices such as computers, Smartphone,tablets and PDA’s.
Personal Area Network Types:
Some type of personal area networks is wired like printer connected with apersonal computer while others are wireless like Bluetooth. Wireless personalarea network is also known as WPANA Wireless Personal Area Network (WPAN) is a personal area network in whichthe connections are wireless. It is a low-power PAN that uses wirelessnetworking technology such as Wifi, Bluetooth or ZigBee. The scope of the WPANvaries from a few centimeters to a few meters.personal area network diagram
Few Examples of Wireless Personal Area Network (WPAN):
An example of a WPAN is using a Bluetooth mouse you’ve connected to a PC tocontrol the computer operations. WPAN is also used in the following tasks. * Wireless keyboards * Wireless Mice * Smartphones * TV remotes * Wireless printers * Gaming consoles * Bluetooth * Fire-wire * ZigBee * Ultrawideband * Wibree * wireless USB
Examples Of Personal Area Network:
1. Body Area Network: Body Area Network is a network that moves with an individual, For example, a mobile phone network moves with a person. Suppose an individual establishes an internet connection and then establishes a connection with another device for sharing information. 2. Offline Network: You can create networks in your home, so it is also known as a home network. Home networks are designed to integrate devices such as printers, computers, TVs but are not connected to the Internet. 3. Small Home Office: It is used to connect a variety of devices to the Internet and corporate networks with a VPN.
Local Area Network (LAN)
A wireless LAN or WLAN is a wireless Local Area Network, which is the linkingof two or more computers without using wires. It uses radio communication toaccomplish the same functionality that a wired LAN has. WLAN utilizes spread-spectrum technology based on radio waves to enable communication betweendevices in a limited area, also known as the basic service set. This givesusers the mobility to move around within a broad coverage area and still beconnected to the network. * IEEE 802.11: IEEE 802.11, the Wi-Fi standard, denotes a set of Wireless LAN/WLAN standards developed by working group 11 of the IEEE LAN/MAN Standards Committee (IEEE 802). The 802.11 family currently includes six over-the-air modulation techniques that all use the same protocol. The most popular (and prolific) techniques are those defined by the b, a, and g amendments to the original standard.The table below summarises the different 802.11 standards:Protocol|Release Date|Op. Frequency|Data Rate (Typical)|Data Rate (Max)|Range (Indoor) —|—|—|—|—|— Legacy|1997|2.4 -2.5 GHz|1 Mbit/s|2 Mbit/s|? 802.11a|1999|5.15-5.35/5.47-5.725/5.725-5.875 GHz|25 Mbit/s|54 Mbit/s|~30 meters (~100 feet) 802.11b|1999|2.4-2.5 GHz|6.5 Mbit/s|11 Mbit/s|~50 meters (~150 feet) 802.11g|2003|2.4-2.5 GHz|11 Mbit/s|54 Mbit/s|~30 meters (~100 feet) 802.11n|2006 (draft)|2.4 GHz or 5 GHz bands|200 Mbit/s|540 Mbit/s|~50 meters (~160 feet)
Wide Area Network (WAN)
A Wide Area Network or WAN is a computer network covering a broad geographicalarea. Contrast with personal area networks (PAN’s), local area networks(LAN’s) or metropolitan area networks (MAN’s) that are usually limited to aroom, building or campus. The largest and most well-known example of a WAN isthe Internet.WAN’s are used to connect local area networks (LAN’s) together, so that usersand computers in one location can communicate with users and computers inother locations. Many WAN’s are built for one particular organisation and areprivate. Others, built by Internet service providers, provide connections froman organisation’s LAN to the Internet.In addition, WAN’s also refer to Mobile Data Communications, such as GSM, GPRSand 3G. Please refer to our Mobility section for further details.
Computer Network Types
A computer network is a group of computers linked to each other that enablesthe computer to communicate with another computer and share their resources,data, and applications.A computer network can be categorized by their size. A computer network ismainly of four types: * LAN(Local Area Network) * PAN(Personal Area Network) * MAN(Metropolitan Area Network) * WAN(Wide Area Network)* * *
LAN(Local Area Network)
* Local Area Network is a group of computers connected to each other in a small area such as building, office. * LAN is used for connecting two or more personal computers through a communication medium such as twisted pair, coaxial cable, etc. * It is less costly as it is built with inexpensive hardware such as hubs, network adapters, and ethernet cables. * The data is transferred at an extremely faster rate in Local Area Network. * Local Area Network provides higher security.* * *
Examples Of Personal Area Network:
* Body Area Network: Body Area Network is a network that moves with a person. For example, a mobile network moves with a person. Suppose a person establishes a network connection and then creates a connection with another device to share the information. * Offline Network: An offline network can be created inside the home, so it is also known as a home network. A home network is designed to integrate the devices such as printers, computer, television but they are not connected to the internet. * Small Home Office: It is used to connect a variety of devices to the internet and to a corporate network using a VPN* * *
Examples Of Wide Area Network:
* Mobile Broadband: A 4G network is widely used across a region or country. * Last mile: A telecom company is used to provide the internet services to the customers in hundreds of cities by connecting their home with fiber. * Private network: A bank provides a private network that connects the 44 offices. This network is made by using the telephone leased line provided by the telecom company.
