described by Institute of Electrical and Electronics Engineers (IEEE) in 802.X standards [4].The first Bluetooth technology was described in 802.15 standards. which is based on 802.X.it had the primary aim to transfer data on layer 3 of the OSI-Model‚ where the Media Access Control (MAC Layer) could work with any of the two radio transmission layers and an infrared layer [6]. MAC Layer is a part of the security mechanism‚ enabling avoidance from collusions‚ during data transmission. Most

Repeater: operates at physical layers of osi model. Digital signals or analog signals that carry digital data can only be transmitted over a limited distance. After a certain distance attenuation or noise endangers the integrity of that data. Repeaters reproduce and transmit the received digital data. This new signal is the exact duplicate of the original signals. Repeaters offer simple means to extend a network‚ increased traffic on the network is introduced. This increased network congestion may

Wide area network is a kind of cross region data communication network using the equipment provided by telecommunications operators as the information transmission platform. Refering to the OSI reference model‚ WAN technologies are mainly located in the bottom three levels. respectively is the physical layer‚ data link layer and network layer (Groth & Skandler‚ 2009). There are three typical types of wide area network. The first one is Public transport

Unit 4 Research Project: MAC Sublayer The Media Access Control (MAC) is one of the sublayers contained in the Data Link Layer (DLL) of the Open Systems Interconnection (OSI) model. The MAC layer provides addressing and channel access control mechanisms‚ and works to transmit data from one Network Interface Card (NIC) to another across a connected network. Carrier Sensed Multiple Access with Collision Detection (CSMA/CD) is the process used by non-switched Ethernet to detect a clear channel between
