What is wireless broadband (WiBB)?

Computer EngineeringComputer NetworkMCA

Wireless broadband (WiBB) a networking technology designed to impart highspeed Internet and data service through wireless networks. Wireless broadband may be delivered through wireless local area networks (WLANs) or wide area networks (WWANs).

Similar to other wireless services, wireless broadband can be either fixed or mobile.

Features of WiBB

  • WiBB is similar to wired broadband service since they connect to an internet backbone, with the difference that they use radio waves instead of cables to connect to the last mile of the network.

  • The range of most broadband wireless access (BWA) services varies around 50 km from the transmitting tower.

  • Download speeds provided by some wireless Internet service providers (WISPs) are over 100 Mbps.

  • WiBB mostly provides asymmetrical data rates for downloads and uploads.

  • WiBB may also be symmetrical, i.e. they have the same data rate in both downstream as well as upstream. This is most seen only in fixed wireless networks.

  • Any device connected to WiBB needs to be equipped with a wireless adapter to translate data into radio signals which can be then transmitted using an antenna.

Types of WiBB

Fixed Wireless Broadband

Fixed WiBB provides wireless Internet services for devices located in more or less fixed locations, like homes and offices. The services are comparable to those provided through digital subscriber line (DSL) or cable modem, with the difference that it has wireless mode of transmission.

The two main technologies used in fixed WiBB are −

  • LMDS (Local Multipoint Distribution System)
  • MMDS (Multichannel Multipoint Distribution Service) systems

Mobile Wireless Broadband

Mobile WiBB, also called mobile broadband, provides high – speed broadband the connection from mobile phone service providers which is accessible from random locations. The locations are within the coverage area of the phone towers of mobile service provider and the connections are subject to monthly service plan subscribed by the user. Mobile broadband can be costlier due to its portability. Also, they generally have varying or limited speed except in urban areas.
