When the concept of a network without wires was first suggested more than two
decades ago, it sparked the imagination of scientists, product vendors, and users
around the globe eager for the convenience and flexibility of a free roaming connection.
Unfortunately, as the variety of wireless solutions began to emerge, anticipation
turned to disappointment.The first wave of solutions proved inadequate
for the networking, portability, and security needs of a changing IT environment.
Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is one of the least secure forms of security.Many laptop computers have wireless cards pre-installed. The ability to enter a network while mobile has great benefits. However, wireless networking is prone to some security issues. Crackers have found wireless networks relatively easy to break into, and even use wireless technology to crack into wired networks......
Hello, in this module we are going to discuss wireless networking. Specifically, we'll take a look at
how wireless technology works, how it is commonly deployed, and the security issues associated
with using it. Because wireless communications can penetrate opaque objects such as buildings, the
risk of someone accessing a private network increases markedly. With wireless, an attacker does not
need to gain access to physical cables or jacks, but only needs to have an antenna and be within
range of the transmissions....
This book provides a comprehensive introduction to the underlying theory, design techniques and analytical tools of wireless communications, focusing primarily on the core principles of wireless system design. The book begins with an overview of wireless systems and standards. The characteristics of the wireless channel are then described, including their fundamental capacity limits. Various modulation, coding, and signal processing schemes are then discussed in detail, including state-of-the-art adaptive modulation, multicarrier, spread spectrum, and multiple antenna techniques....
Insider attacks pose an often neglected threat scenario when
devising security mechanisms for emerging wireless technologies.
For example, traffic safety applications in vehicular
networks aim to prevent fatal collisions and preemptively
warn drivers of hazards along their path, thus preserving
numerous lives. Unmitigated attacks upon these networks
stand to severely jeopardize their adoption and limit the
scope of their deployment.
Welcome to the world of Cisco Certified Network Associate (CCNA) Wireless! As technology
continues to evolve, wireless technologies are finding their way to the forefront.
This clearly indicates the progression from a fixed wired type of connectivity to a more
fluid, mobile workforce that can work when, where, and how they want. Regardless of
your background, one of the primary goals of the new CCNA Wireless certification is to
introduce you to the Cisco Unified Wireless Network (CUWN).
The expansion and popularity of the Internet, along with the addition of wireless data functionality to wireless networks, has also contributed greatly to the growth of the wireless industry. In fact, the anticipated consumer demand for high bandwidth wireless data is commonly seen as the driving force behind current network upgrades and expansions. The number and types of companies aggressively investing in wireless technologies illustrate the importance of wireless data.
In this chapter, you will learn to:
Describe the enterprise requirements for providing teleworker services, including the differences between private and public network infrastructures. Describe the teleworker requirements and recommended architecture for providing teleworking services. Explain how broadband services extend enterprise networks using DSL, cable, and wireless technology.
The provision of wireless access to the Public Switched Telephone Network (PSTN) from a customer premises is known as Wireless Local Loop (WLL). The potential markets of application of WLL range from developing countries to developed ones. In both cases, the liberalization of the telecommunications market has allowed competition among operators around the world. Many communities of difficult access are still waiting for basic telephone service, which could be viable only by wireless technology, which, besides, offers a fast and cost-effective option....
Wireless e-business allows people to communicate and transact in business via
wireless technology, without physical connectivity, such as wires or cabling.
Wireless e-business uses many devices, including mobile phones, pagers, palmpowered
personal computers (PCs), pocket PCs, laptop computers, and other mobile
devices or devices connected to the wireless networks
(BQ) Data Communications and Computer Networks: A Business User's Approach will give you the thorough understanding you need of basic features, operations, and limitations of ifferent types of computer networks. This book offers full coverage of wireless technologies, industry convergence, compression techniques, network security, LAN technologies, VoIP, and error detection and correction.
Recently, many telecommunications operators have been looking for wireless technology to replace parts of the hard-wire infrastructure. The wireless local loop (WLL) technology  is considered as the most fitting solution as radio systems can be rapidly developed, easily extended, and are distance insensitive. Since a WLL eliminates the needs (such as wires, poles and ducts) essential for a wired network, it can significantly speed up the installation process. A typical WLL system may consist of hundreds or thousands of base stations (BSs).
Wireless Technology: Protocols, Standards, and Techniques has sorted it out for you. From basic principles to the state of the art, it furnishes clear, concise descriptions of second and third generation wireless technologies. The bestselling author of the Foundations of Mobile Radio Engineering has gathered together the most up-to-date networking standards, techniques, and protocols and incorporated clear, concise treatments of the necessary background material to form the most current and complete wireless reference available....
The use of radio-frequency communication—commonly referred to
as wireless communication—is becoming more pervasive as well as more
economically and socially important. Technological progress over many
decades has enabled the deployment of several successive generations
of cellular telephone technology, which is now used by many billions
of people worldwide; the near-universal addition of wireless local area
networking to personal computers; and a proliferation of actual and proposed
uses of wireless communications.
Wireless technology has enormous potential to change the way people and things communicate. Future wireless networks will allow people on the move to communicate with anyone, anywhere, and at any time using a range of high-performance multimedia services. Wireless video will support applications such as enhanced social networking, distance learning and remote medicine. Wireless sensor networks can also enable a new class of intelligent home electronics, smart and energy-efficient buildings and highways, and in-body networks for analysis and treatment of medical conditions....
