Wireless networking is the type of networking that confined in computer. The type of the network is provided in wireless. It is commonly shared with telecommunication network of specific location and specific vendor. The data transmission is done though the wireless router and the frequency is passed through radio wave. On describing the type of network there are several service categories found. Wireless LAN, wireless PAN, wireless WAN and mobile device networks.
Wireless personal area networks
Wireless personal Area Networks (WPAN) usually connect device into a smaller area with internally. This is confined with connecting of one member. One of the common examples is Bluetooth services. Bluetooth provides a WPAN for connecting in small area like headphone to PC Bluetooth device, PC to mobile connection, data transfer from one device to another device.
Wireless LAN or wireless local area network connects few like two or more devices with each other. And access a single point of internet through it. There are two subtypes of WLAN. One of them is Wi-Fi and the other is fixed wireless data. Wi-Fi is used as 802.11 WLAN and the fixed wireless data implies single point to point connections between networks of two different locations.
Wireless MAN mean wireless metropolitan area networks are a type of networking in broad term used to establish connect ion in a broad space or area like metropolitan cities. Commonly the WiMAX term is used for describing wireless metropolitan area networks. The total coverage is considered in IEEE 802.16d/802.16e.
Wireless WAN or wireless wide area networks that cover all the outdoor area. The network connects to a local office. They can provide 2 to 2.4 GHz bandwidth. The total system contains station gateways, access point and relay.
Increasing mobile phone usage
Due to increase mobile phone usage cellular networks start wireless network base internet service. There are three subtypes. One of them is GSM that is global system form mobile communications. It includes switching, base station, operating system. The cell phone connects to all of these three things step by step. Other subtype is PCS that’s Personal Communications service. It is a radio band that can be used not much area usually in America and south Asian countries. The last subtype is D-AMPS that are digital advanced mobile phone services.
The ultimate destiny of the wireless networking is to connect all together in a single point. A common channel is used to connect to internet all over the provided area. Some services are costly while some are cheap. It varies from countries to countries on based of the supply by the vendor.
Disadvantage of wireless network
The most dangerous thing of wireless networking is the attack and damage of locally stored data in local PCs by the hackers. The security system has to be high enough to control and protect the service. The bad effects of Wireless communication are the radiation that can cause harm to cell as well as to nervous system. So we should have to concern about the service as well as about our health. And necessary steps should be taken to prevent it.
Wireless routers
Wireless routers are used to connect the wireless drive with the service providers. These are used as media of connectivity only. They are in different value and different range. So the prize and quality also varies from each. Top 10 wireless routers are Cisco Linksys E3000, Cisco Valet plus, Netgear WNDR3700 Range max dual band, D-link DIR-615 wireless N router, netgear wireless router WNR2000, Novatel wireless MiFi 2200, D-link xtreme n storage Router DIR-685, Belkin N+ wireless router, D-link xtreme N dual band gigabit router DIR-825.
Security of the networking is very important. On network security certification there are some certificates that have to pass on the wireless service. By which primary security module can be maintained all over the network are.
