Local Area Network Technologies

Paper Summary:

This paper provides a brief look at "IEEE 802.11" and "Bluetooth", two of the important wireless LAN technologies. A comparison of the two technologies follows a description and explanation of their physical layers, medium transmission characteristics, primary tasks, protocols, and spectrum techniques.

From the Paper:

"The IEEE 802.11 (First adapted in 1997) is primarily a standard developed to provide time bound and asynchronous wireless services. The MAC layer is meant to handle different physical layers with distinct medium and transmission characteristics. The standard uses 2.4 GHz ISM band and a minimum data transfer rate of 1 Mbits /s. IEEE 802.11 specifies the physical and the medium access layer standards in particular to the wireless LAN's. IEEE 802.11 has seamless integration with other standards for wired networks. The Data link layer and the Logical Link layer control other aspects pertaining to different forms of the media. The MAC layer is concerned with three main tasks namely medium access, data fragmentation and encryption while the Physical layer takes care of the modulation, encoding and decoding of the signals. Let us study these two layers in a little detail."
