List the capabilities of third generation systems. List the challenges faced by WLAN industry. 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. List the services of security it can be classified.


What are the limitations of GPRS? What are the functions of physical layer of IEEE List the features of networs LAN. The main objective of GSM is to remove ecc2043 incompatibility among the systems by allowing the roaming phenomenon for any cell phone. Explain the three different functions that are used for the operational differences for MAC layer.

Explain the architecture, location and handoff management in GPRS network. EC Wireless Network – Question bank.

  ISO 11608-1 PDF

The access methods for wireless LANs are as follows: What is the data rate of Bluetooth? What was the mission of the IAPP group? Explain three different functions that are used for operational differences for MAC layer. List the challenges involved in Adhoc network architecture. Explain the architecture of IEEE MSC A checks if the MS has made too many handoffs recently this is to avoid, for example, numerous handoffs between BS1 and BS2 a where the MS is moving within the overlapped area or if intersystem trunks are not available.

List the five types of logical channels in Bluetooth. What is the frequency band and channel bandwidth specification of Wirelesz Standard? List the logical channels provided by L2CAP.

Explain the source initiated routing protocols for ad hoc networks in detail. Skip to main content. Explain the need for demand based routing protocol for wireless sensor networks. Skip to main content. Dhanalakshmi College of Engineering, Chennai. The aim of IEEE Explain in detail the performance of fixed assignment access methods with traffic neworks and delay estimation methods.

Handoff can be classified into two different types: April Part B 1.

Draw the frame format of IEEE Describe the architecture of wireless sensor network. List the services wireless system security Determine the transfer time of a 20 kB file with a mobile data network with the transmission rate of 10 Kbps. What is meant by AMPS?


Consider the following information for network design: What is meant by soft handoff? Handoff basically involves change of radio resources from one cell to another adjacent cell. Due to fading, packets from different transmitting stations can arrive with different transmitting power values.
