802.11b – 802.11b is one of the IEEE standards for wireless LANs and specifies a data
transfer rate of 5.5 and up to 11 megabit per second in the 2.4 gigahertz radio band. 802.11b
is recently given other widespread names as Wi-Fi or Wireless Fidelity.
802.11g – 802.11g is the newest addition of the IEEE standards for wireless LANs and
specifies a data transfer rate up to 54 megabit per second in the 2.4 gigahertz radio band.
802.11g is also part of the family of Wi-Fi.
Ad-hoc Network – Ad-hoc network, also known as peer-to-peer network, means a wireless
network which is composed only of stations. This type of network is created with a group of
wireless-equipped computers. With the wireless devices, each computer, functioning as a
server and a client at the same time, can establish a LAN to directly communicate with other
computers without any access points involved. It is easy to set up a peer-to-peer network;
however, because all stations must be within a specific distance in order to be capable of
communicating with each other, it is also limited. Thus, such a type of network is widely used
at small networking requirements, like between a few computers or devices at departmental
scales.
