Informaition Technology Example

Informaition Technology Example Informaition Technology â€" Assignment Example > 30th April 2010Comparison of the IEEE 802.15.1 Bluetooth protocol stack to the OSI modelIEEE 802.15.1 Bluetooth protocol stack is based on the Bluetooth technology, and it is commonly used in cases of wireless personal area network. Some of the features associated with this technology include low cost, short range, small networks, and communication within a radius of less than ten meters. On the other hand, OSI model defines a layered communication layer that is utilised in network protocol design especially in computers. OSI model divides the network architecture to seven distinct layers that complement each other (Cooklev, 2004). These seven layers each has specific role that ensures information and data is passed from one network link to another ensuring integrity of the entire process is championed. IEEE 802.15.1 Bluetooth protocol stack also has layers that aides the transfer of data and voice into ensuring the process of communication is fulfilled. Thus, the two technologies play a major role that is similar to some extent, which means that there are certain features that they share. OIS and IEEE 802.15.1 Bluetooth protocol stack share certain technological characteristics, especially the data link layer and physical layer of OSI model. These two layers complements with four sub-layers of IEEE 802.15.1 Bluetooth protocol stack model (Walke, Mangold Berlemann, 2006). RF layer is associated with antenna power range; the baseband layer allows establishment of Bluetooth physical link that exists between the devices been connected â€" forming a piconet, the link manager allows setting up links between the Bluetooth devices in question. Other tanks that are completed by the link manager include power mode, security and connection states of devices. The Logical Link Control and Adaptation Protocol (L2CAP) provide a medium in which upper layer protocols can communicate with each other easily (Angelescu, 2009). IEEE’s Project 802The IEEE 802 is a name that is given to standards that deals with metropolitan area networks and local area networks. This means that the project considerations for those networks that vary variable size packets; this differs with other technologies such as the cell-based network in which data is transmitted uniformly in units called cells, or isochronous networks in which data is transmitted in streams (Angelescu, 2009). The number 802 originates from three next free numbers that could be assigned by IEEE; it is also associated with the first meeting, which took place in February 1980. The protocols and services that are specified in the IEEE 802 are mapped to the physical link and data link of the OSI model. Furthermore, the IEEE 802 further splits the Data Link layer into two layers that are commonly referred to as Media Access Control (MAC) and Logical Link Control (LLC). Because of its presences in the OSI model, the layers become Data Link Layer (with MAC Sub-layer and LLC Sub-layer), and the Physical Layer (Dubendorf, 2003). During the IEEE meeting, different proposals were presented in which the entire project was divided into three groups. Group IEEE 802.1 dealt with general architecture that brought into consideration bridging techniques and VLAN, the second group, IEEE 802.2 were response for Logical Link Control Protocols such as Internet Protocol, and the third group, IEEE 802.3 were responsible for the medium and physical access control requirements and are credited for producing over 30 standards. Other and newer committees that played a major role in defining networking fundamentals include IEEE 802.11 for wireless LANs (Wi-Fi) and IEEE 802.16 were responsible for Wi-Max (Walke, Mangold Berlemann, 2006).
