  WiMAX: WiMAX stands for Worldwide Interoperability for Microwave Access. It is a type of telecommunication
           technology that provides wireless transmission from multi-point links to portable and fully mobile Internet
           access whose range of operation is within 50 km radius from base station. This technology provides speed
           up to   Mbps. I    standard for  iM   is    .  . It can connect to Internet connection from far off
           location and enables to establish wireless Internet network in a campus.

          Satellite: Satellite services can provide broadband Internet access in rural or outlying areas unreached by
           wired phone lines or cable connections. Similar to wireless access, satellite connection utilises a modem.
           Satellite accesses the Internet via a satellite in Earth’s orbit. The enormous distance that a signal travels
           from earth to satellite and back again  provides a delayed connection compared to cable and  S .

          Its installation is similar to satellite    connection but runs on different antennas and receiving e uipments.
           Wiring connects the antenna to a modem device which is connected to your computer. Bandwidth and
           uptime can be degraded by rain, snow and high wind.
          Mobile Internet: If there is one technology to name that has revolutionised the way people are contacting
           or communicating with each other in the last 20 years, it must be ‘Mobile Cellular Technology’.

          Portable devices have been in process of huge changes. The data transfer or download speed varies
           with the congestion of the network towers, nature of the data, etc., that have considerably changed and
           have been upgraded in last    years and thus we can classify the era of mobile technology in different
           generations as:

          i.   First  Generation (1G) was introduced  in 1980s. It was used for voice services and was based on
             technology called as  dvanced Mobile  hone System   M S .
          ii.   Second Generation (2G) was introduced in late 1990s. It was based on digital technology and Short
             Message Service  SMS . It used digital signals for voice transmission. It enabled text messaging.  lso
             Pagers were introduced for text messaging.

          iii.   Third Generation (3G) enabled higher rate of data transmission and provided multimedia support. In
             this generation, wireless technology is more enhanced over previous wireless technologies. Thus, it has
             helped in high-speed transmission, advanced multimedia access, video streaming, video chatting on
             wireless signal, etc. It has been commonly in use after year 2000.

          iv.   Fourth Generation (4G) of cellular service has integrated features of 3G with Internet compatibility to
             support wireless mobile Internet  as the data transmission speed in Standard     or         is around
             five to seven times faster than   .    provides same features as    but with high data transfer speed. It
             provides data transfer speed around  5 Mbps. It enables for flawless service in applications like wireless
             broadband access  Multimedia Messaging Service  MMS   video chat  mobile          content and  igital
              ideo  roadcasting      .
        Some use  i-Max technology in their    network  while other uses technology called  ong  erm  volution
        or     in    Network in India.


            INTERNET ACCESS THROUGH WI-FI
        An access point is required when we subscribe to an Internet connection. The ISP provides options to purchase
        or rent a Wi-Fi router that can act both as an Internet connectivity device and as an access point for Wi-Fi
        connectivity.
