Wireless Broadband is a fairly new technology that provides data network access over a wide area and high-speed wireless internet. The main thing is that the internet facility is not limited with the wired networks. Now you can access the internet from anywhere provided you have a laptop with you and an access point near by. Two things are needed for wireless connectivity. One is the access point which sends the data in the forms of radio waves and the other is wireless router which receives the radio waves and sends it the computer.
Some Wireless Internet Service Providers (WISPs) provide access services are estimated to have a range of 50 km (30 miles) from a tower and download speeds of over 100 Mbit/s. Technologies used include MMDS and LMDS, as well as the IEEE 802.16 has standardised one access technology which is also known as WiMAX and heavy use of the ISM bands. WiMAX has yet to get complete acceptance in US because deployment cost does not satisfy the return on investment figures. But it is highly popular in Europe.
Mobile Broadband is a wireless broadband technology which includes new services from companies such as Sprint, AT&T Mobility and Verizon which allow a broadband access with more mobile version. Consumers can purchase a laptop card, USB equipment or PC card via cell phone towers. Such connection will be available without any intervention at any area where there is a strong cell phone connection. For portable convenience these connections can cost more as well as having speed limitations in all but urban environments.
The major advantages of wireless broadband are the avoidance of mesh of wires and the mobility of internet connection. Every computer that exists within the wireless network will need to have a receiver which works with the wireless router. These are referred to as being network adapters, and they will typically have either a USB device or a network card. For most laptops, a network card adapter can be used, but most contemporary laptops today have such devices built in. Most of the ISPs in UK like AOL, BE or BT provide wireless supports with free of cost or with minimum prices. These ISPs also provide certain broadband bundles suitable for wireless network supports.
