The telecom industry is on the rebound and the demand for more and newer wireless services is ever increasing. To meet these market demands, wireless providers have to deploy advanced radio access networks to enhance the mobile communications infrastructure. This forward-looking book delivers a comprehensive overview of the evolution of mobile radio access networks, focusing on high-level architectural issues that engineers and managers need to understand.
For some years, commentators have been predicting the 'convergence' of the Internet and
mobile industries. But what does convergence mean? Is it just about mobile phones providing
Internet access? Will the coming together of two huge industries actually be much more about
collision than convergence? In truth, there are lots of possibilities about what convergence
might mean, such as:
• Internet providers also supply mobile phones - or vice versa, of course.
• The user's mobile phone is replaced with a palmtop computer.
• The mobile Internet leads to a whole range of new applications.
AD HOC NETWORKS: Technologies and Protocols is a concise in-depth treatment of various constituent components of ad hoc network protocols. It reviews issues related to medium access control, scalable routing, group communications, use of directional/smart antennas, network security, and power management among other topics. The authors examine various technologies that may aid ad hoc networking including the presence of an ability to tune transmission power levels or the deployment of sophisticated smart antennae. ...
Data Communications and Networking, 3/e provides a comprehensive and current introduction to networking technologies. The book is accessible to students from all backgrounds and uses hundreds of figures to visually represent concepts. The new edition has been completely updated to reflect the constantly changing world of network technologies. Enhanced coverage of bluetooth, wireless, satellites, as well as four new chapters on security have been added. The third edition has transitioned from using the 7-layer OSI model to the 5-layer Internet Model.

This document guides customers in their planning or deployment of IPv6 in campus networks. This
document does not introduce campus design fundamentals and best practices, IPv6, transition
mechanisms, or IPv4-to-IPv6 feature comparisons. Document Objectives, page 3 provides additional
information about the purpose of this document and references to related documents.
Development of packet-switched data communication networking
technologies has been rapid in recent years, a phenomenon made
possible by the open standardization process and the potential
new territories for intellectual property creation. As a consequence,
new ways of creating services have been devised, bringing more
flexibility as compared to traditional telecommunications schemes.
Topologies and Access Methods
Describe the basic and hybrid LAN physical topologies, and their uses, advantages and disadvantages
Describe the backbone structures that form the foundation for most LANs
Compare the different types of switching used in data transmission
Understand the transmission methods underlying Ethernet, Token Ring, FDDI, and ATM networks
Describe the characteristics of different wireless network technologies, including Bluetooth and the three IEEE 802.11 standards
Carrier Sense Multiple Access (CSMA) is a probabilisticMedia Access Control (MAC) protocol in which a node
verifies the absence of other traffic before transmitting on a shared transmission medium
CAN uses a nondestructive bitwise arbitration, which means that messages remain intact after arbitration is
completed even if collisions are detected. All the arbitration takes place without corruption or delay of the
message that wins the arbitration.
•As PC became more common, it became obvious one would need
to share data and peripherals between them efficiently.Floppy discs could not be the solution. Hence the idea of a
network.•The necessities to have one database that many users can
access simultaneously made networking very relevant.•Great demand to share devices ( e.g. printer sharing in companies).
The BACnet protocol currently uses the connectionless User Datagram Protocol (UDP)
for both Annex H and BACnet/IP communications. However, it is possible that Trans-
mission Control Protocol (TCP) transport will be utilized for some service in the future,
and so threats specific to TCP have been included. Even if TCP/IP is never used as part
of the BACnet protocol, it still can be used to gain access to the building control system
web servers, get access through the corporate firewall, and be used for denial of service
attacks on the external network on which the BCS may depend.
In this chapter, students will be able to understand: Password policies ensure that users choose effective passwords; user-level security requires a separate account for each user; in share-level security, all users access shares by using the same passwords; a firewall is a hardware or software product that protects a network from unauthorized access, using techniques such as packet filtering, NAT, or proxy servers;...
Chapter summary: The Windows NT, Windows 2000, and UNIX operating systems include both server and client functionality; Novell NetWare is strictly a client/server network operating system; Windows NT and Windows 2000 were designed to provide application services and file and print services; a client is a software component that enables a computer to access server resources;...
This chapter includes contents: Types of remote network connections, public switched telephone network (PSTN), modems, modem communications, configuring a modem, Virtual Private Network (VPN) communications,...
Module 5 - Configuring wireless network connections. This module describes key wireless network technologies and how to configure wireless network components and the Windows 7 elements that are necessary to access wireless networks.
Four laws, two each from the natural sciences and the social sciences, have formed the basis for the development of digital wireless communication networks. This essay describes their interaction, as well as their logical support for spread - spectrum multiple - access techniques.
Java(TM) Network Programming and Distributed Computing is an accessible
introduction to the changing face of networking theory, Java(TM) technology, and the
fundamental elements of the Java networking API. With the explosive growth of the
Internet, Web applications, and Web services, the majority of today's programs and
applications require some form of networking. Because it was created with extensive
networking features, the Java programming language is uniquely suited for network
programming and distributed computing....
he new Cisco certifications reach beyond the popular certifications,
such as the MCSE and CNE, to provide you with an indispensable factor in
understanding today’s network—insight into the Cisco world of internetworking.
This book is intended to help you continue on your exciting new
path toward obtaining CCNP and CCIE certification. Before reading this
book, you should have at least read the
CCNA: Cisco Certified Network
Associate Study Guide
(Sybex, 2000). While you can take the CCNP tests in
any order, you should pass the CCNA exam before pursuing your CCNP.
