What Is Wireless Computer Broadbanding?
Wireless computer broadbanding, or wireless broadband (also called Wi-Fi or WiBB), provides access to high-speed Internet via wireless technology. Wireless broadband links computers in a network so they can share an Internet connection without having to use cumbersome wires. Computers on a local area network (LAN) and a wide area network (WAN) can be connected wirelessly, which effectively increases the operational size of the network.

Wireless Broadbanding Basics
-
Wireless broadband communication uses radio waves to provide access to high data-rate Internet service. It broadcasts information between senders and receivers without any physical transmission medium (cables or wires). Wireless broadband uses radio frequency transmission technology. The transmitted data is converted into radio waves by a computer's wireless adapter. A router (at the receiving end) accepts and decodes the radio waves broadcast by an antenna. The router forwards the decoded data onto the Internet via an Ethernet connection (which is a wired, physical connection). This process is two-way. The wireless router converts information received from the Internet into radio waves, and transmits it to the wireless adapter. The adapter then reconverts the waves into data, which is then manipulated by the receiving computer.
Wireless Broadbanding Hardware Requirements
-
Wireless computer broadbanding communication comprises various hardware devices, including wireless routers, each consisting of a wireless access point, software firewall, Ethernet hub, router and a port that connects to a DSL modem or cable; and wireless network adapters, also called wireless network interface cards, or NICs.

Wireless Broadbanding Types
-
There are various types of wireless broadbands based on the protocols used. They include 802.11a (with an average speed of 27 Mbps and a wireless range of 12 meters indoors), 802.11b (with an average speed of 4.5 Mbps and a wireless range of 30 meters indoors) and 802.11g (with an average speed of 7 Mbps and a wireless range of 30 meters indoors). These communication protocols are defined by the IEEE (Institute of Electrical and Electronics Engineers), which sets standards for wireless Internet communication.
Advantages of Wireless Broadbanding
-
Wireless broadbanding is cheaper, faster and an easier way of communication than wired broadband Internet access. It reduces costs of expensive wiring, cables and associated hardware equipment. Wireless broadbanding supports roaming, which enables users to access the Internet on the go.
Disadvantages of Wireless Broadbanding
-
Wireless networks are more prone to hackers, viruses and other infiltrations than are wired networks. Setting up wireless computer broadbanding requires ample technical know-how and cannot be attempted by a layperson. Wireless networks are limited in range, with the average transmission range being approximately 45 meters indoors and 90 meters outdoors. Wi-Fi broadband data transmission can be interrupted by other nearby devices, including microwave ovens and cordless telephones.
