Wire up with wireless network

A basic wireless network consists of multiple stations communicating with radios that broadcast in either the 2.4GHz or 5GHz band

Wireless network is a network set up by using radio signal frequency to communicate among computers and other network devices. This network is getting popular nowadays due to easy to setup feature and no cabling involved. You can connect computers anywhere in your home without the need for wires.

Wireless Personal Area Networks (WPANs) interconnect devices within a relatively small area, generally within reach of a person. For example, Bluetooth provides a WPAN for interconnecting a headset to a laptop. Wi-Fi often use dedicated microwave or laser beams over line of sight paths. It is often used in cities to connect networks in two or more buildings without physically wiring the buildings together. Wireless Metropolitan area networks (WMANS) are a type of wireless network that connects several Wireless LANs. Wireless Wide Area Networks (WWANs) are wireless networks that typically cover large outdoor areas. These networks can be used to connect branch offices of business or as a public internet access system. They are usually deployed on the 2.4 GHz band.
With the development of smart phones, cellular telephone networks routinely carry data. Like the GSM (Global System for Mobile Communications) network is divided into three major systems: the switching system, the base station system, and the operation and support system. The cell phone connects to the base system station which then connects to the operation and support station; it then connects to the switching station where the call is transferred to where it needs to go. GSM is the most common standard and is used for a majority of cell phones. Personal Communications Service (PCS) is a radio band that can be used by mobile phones in North America and South Asia. Sprint happened to be the first service to set up a PCS. D-AMPS is Digital Advanced Mobile Phone Service, an upgraded version of AMPS, is being phased out due to advancement in technology. The newer GSM networks are replacing the older system.
Since from the time of World War-II, wireless networks have always been very useful in transferring data from one place to other with efficiently and reliably. Cellular phones are one of the best examples, that we use everyday to communicate with others. Sending information overseas using satellites, Emergency services such as the police department utilize wireless networks to communicate important information quickly. In businesses use it to send and share data quickly whether it is in a small office building or across the world. Another feature that is making it more popular is its inexpensive and rapid nature to connect to the Internet in countries and regions where the telecom infrastructure is poor or there is a lack of resources, as in most developing countries.
Apart from all its good point there are some issue that causing problem, like Compatibility, Different components not made by the same company may not work together. Other than that Wireless networks are typically slower than those that are directly connected through an Ethernet cable.
A wireless network is more vulnerable, because anyone can try to break into a network broadcasting a signal, so security is another issue that is causing problem in its way of popularity. In recent times, there have been increased concerns about the health issues, the possible risk of tumors and other diseases due to exposure to electromagnetic fields (EMFs) needs to be further investigated. Other than these issues, wireless communication is gaining popularity due to its flexible nature.
