Welcome to Wireless Home Networking For Dummies. Wireless networking for personal computers is not really a new idea; it’s been around for at least five years. The emergence of an industry standard, however, has caused the use of wireless networking technology to explode. One of the most appealing things about the current crop of wireless networking equipment is the ease with which you can set up a home network, but its reasonable price might be the most attractive aspect of all. Setting up a wireless home network can be both inexpensive and easy.

Wireless network refers to any type of computer network that is not connected by cables of any kind. It is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.[1] Wireless telecommunications networks are generally implemented and administered using a transmission system called radio waves. This implementation takes place at the physical level (layer) of the OSI model network structure....

The purpose of current study is presenting a framework for implementation of wireless networks in hospitals to use in nursing care. In the proposed framework, implementation key aspects that include the purpose, application domains, and the functions of wireless terminals, network technology, mobile devices, user interface and the information structure of the system have described in the logical framework. Because, the framework has presented based on scientific principles and the experiences of other countries, it can be an appropriate framework for future efforts in this field.

Mobile Ad Hoc wireless Networks (MANETs) is defined as a multi-hop infrastructureless wireless network which is self-organized and connects two or more stations spontaneously in the absence of central point or any access point. It allows peer-to-peer connections between devices that are operating in ad-hoc mode and are within the wireless range. They can form standalone groups of wireless nodes and can be connected to a cellular or fixed network. Nodes in a mobile adhoc network are free to move and organize themselves in an arbitrary fashion.

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......

A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the same wireless network.

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....

A WLAN is a shared network. An access point is a shared device and functions like a shared Ethernet hub. Data is transmitted over radio waves. Two-way radio communications (half-duplex) are used. The same radio frequency is used for sending and receiving (transceiver).

IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6, 5 and 60 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent amendments. These standards provide the basis for wireless network products using the Wi-Fi brand.

Over the last couple of years, manufacturers have produced some incredibly sophisticated wireless networking equipment. Consumers’ ongoing demand for low-cost, high-speed, easy-to-use networking gear has forced hardware manufacturers to continually refine their designs. Engineers have produced tiny devices that use very little power to perform amazing feats of ingenuity, producing them on such a large scale that the cost is staggeringly low.

OpenBSD's stateful packet filter, PF, offers an amazing feature set and support across the major BSD platforms. Like most firewall software though, unlocking PF's full potential takes a good teacher. Peter N.M. Hansteen's PF website and conference tutorials have helped thousands of users build the networks they need using PF. The Book of PF is the product of Hansteen's knowledge and experience, teaching good practices as well as bare facts and software options.

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....
