ECWireless Networks-Lecture notes for unit 1-edition
List the two major states in the operation of Bluetooth. List the four layers involved in SMS. Then the station transmits its packet. Explain the IEEE What is random back off delay? Nltes the source initiated on- demand routing protocols in ad- hoc networks in detail. Explain the architecture, location and handoff management in GPRS network.
How the hard Handoff is characterized? List the challenges faced by WLAN industry. List the services networkz by IEEE Explain in detail the random access for mobile data services and wireless LAN data services.
EC Wireless Networks – Study Material – Unit I | Devasena A. –
Help Center Find new research papers in: List out the difference between 1G and 2G systems. Explain the three different functions that are used for wireless operational differences for MAC layer. CSMA-based wireless random access technique. Describe the different handoff mechanism. Explain in detail about Bluetooth architecture 8.
noted Click here to sign up. List the table driven protocols. List the five major challenges for implementation of Wireless LANs that existed from the beginning of this industry.
It is known as non-persistent sensing mechanism. Handoff basically involves change of radio resources from one cell to another adjacent cell.
Draw the MAC management frame format. Explain in detail the witeless of the 2G GSM system.

A wireless bridge is a hardware component used to wirepess two or more network segments LANs or parts of a LAN which are physically networrks logically by protocol separated. Leave a Reply Cancel reply Your email address will not be published. Explain the Wi- Max layer in detail. Dhanalakshmi College of Engineering, Chennai.
A MS does this by storing the phone number or the number used to contact the MSpersonal identification number for the station, authentication parameters, and so on in the SIM card.
A wireless local area network WLAN links devices via a wireless distribution method typically spread-spectrum or OFDM radioand usually provides a connection through an access point to the wider internet. The packet length is large in LANs.
MSC A checks if the MS has made too many handoffs recently this is to avoid, for example, numerous handoffs between BS1 and Networkks a where the MS is moving within the overlapped area or if intersystem trunks are not available. Explain the source initiated routing protocols for ad hoc networks in detail. It also supports speech transmissions between MSs, emergency calls, and digital data transmissions.
Transmission resources are wasted if there is no voice transmission. Compute the maximum netdorks of a pure ALOHA networking with a large number of users and transmission rate of 1 Mbps? How contention based protocols are classified?
What are hybrid protocols? EC Wireless Networks E. What is meant by soft handoff? Explain the routing protocols of wireless sensor networks in detail. These resources are used for data services which does not require severe delay.
Find out the remedies to the challenges and issues and discuss in detail about it. Every time the MS has to communicate with a BS, it must correctly identify itself. Explain the key features of routing protocol in WSN and discuss any two netwprks efficient routing protocols. List the five types of logical channels in Bluetooth. Access point captures from the packet terminal 1. The main objective of GSM is networrks remove any incompatibility among the systems by allowing the roaming phenomenon for any cell phone.
Draw the frame format of IEEE How many physical channels rc2043 available in each IS carrier? The switch bridges the new path with the old path and informs the MS to transfer from the old channel to the new channel.
