Bluetooth Architecture

Bluetooth Architecture

The Bluetooth architecture, showing all the major layers in the Bluetooth system, are depicted in the Fig. The layers below can be considered to be different hurdles in an obstacle…
Bluetooth

Bluetooth

Introduction Bluetooth wireless technology is a short-range radio technology, which is developed for Personal Area Network (PAN). Bluetooth is a standard developed by a group of electronics manufacturers that allows…
Wireless LANs

Wireless LANs

Introduction In the last two decades the wired version of LAN has gained wide popularity and largescale deployment. The IEEE 802.3 standard has been revised and extended every few years.…
Gigabit Ethernet

Gigabit Ethernet

Brief History and the IEEE 802.3z Task Force As applications increased, the demand on the network, newer, high-speed protocols such as FDDI and ATM became available. However, in the last…
100 BASE TX

100 BASE TX

This option uses two pairs of category 5 UTP or two shielded twisted-pair (STP) cable to connect a station to hub as shown in Fig. One pair is used to…
100 BASE-T4

100 BASE-T4

This option is designed to avoid overwriting. It is used for half-duplex communication using four wire-pairs of the existing category 3 UTP cables, which are already available for telephone services…
High Speed LANs – CSMA/CD based

High Speed LANs – CSMA/CD based

Introduction In the preceding lesson we have seen that high-speed LANs have emerged broadly into three types - based on token passing, successors of Ethernet and based on switching technology.…
Fault Tolerance

Fault Tolerance

FDDI provides a number of fault-tolerant features. In particular, FDDI's dual-ring environment, the implementation of the optical bypass switch, and dual-homing support make FDDI a resilient media technology. Dual Ring…
Token Bus (IEEE 802.4)

Token Bus (IEEE 802.4)

Token BUS: A Brief History Although Ethernet was widely used in the offices, but people interested in factory automation did not like it because of the probabilistic MAC layer protocol.…
IEEE Ring LANs

IEEE Ring LANs

Introduction In the preceding lesson we have mentioned that for the fulfilment of different goals, the IEEE 802 committee came up with a bunch of LAN standards collectively known as…
