Wireless Devices

Digital Enhanced Cordless Telecommunications Technical development and adoption

These channels are reserved exclusively for voice communication applications and therefore are less likely to experience interference from other wireless devices such as baby monitors and wireless networks.

Digital Enhanced Cordless Telecommunications Features

Interference-free wireless operation to around 100 metres (109 yards) outdoors, much less indoors when separated by walls. Operates clearly in common congested domestic radio traffic situations, for instance, generally immune to interference from other DECT systems, Wi-Fi networks, video senders, Bluetooth technology, baby monitors and other wireless devices.

Baby monitor Wired and wireless

Wireless systems use radio frequencies that are designated by governments for unlicensed use. For example, in North America frequencies near 49 MHz, 902 MHz or 2.4 GHz are available. While these frequencies are not assigned to powerful television or radio broadcasting transmitters, interference from other wireless devices such as cordless telephones, wireless toys, computer wireless networks, RADAR, Smart Power Meters and microwave ovens is possible.

Residential gateway Types

Wireless routers perform the same functions as a router, but also allow connectivity for wireless devices with the LAN, or between the wireless router and another wireless router. (The wireless router-wireless router connection can be within the LAN or can be between the LAN and a WAN.)

Bluetooth Adopted protocols

WAE specifies an application framework for wireless devices and WAP is an open standard to provide mobile users access to telephony and information services.

Computer network Geographic scale

A PAN may include wired and wireless devices

Wi-Fi Standard devices

A wireless access point (WAP) connects a group of wireless devices to an adjacent wired LAN. An access point resembles a network hub, relaying data between connected wireless devices in addition to a (usually) single connected wired device, most often an Ethernet hub or switch, allowing wireless devices to communicate with other wired devices.

Wi-Fi Standard devices

Wireless network bridges connect a wired network to a wireless network. A bridge differs from an access point: an access point connects wireless devices to a wired network at the data-link layer. Two wireless bridges may be used to connect two wired networks over a wireless link, useful in situations where a wired connection may be unavailable, such as between two separate homes.

Wi-Fi Standard devices

Wireless devices connected through repeaters will suffer from an increased latency for each hop, as well as from a reduction in the maximum data throughput that is available

Radio

In recent years the more general term “wireless” has gained renewed popularity through the rapid growth of short-range computer networking, e.g., Wireless Local Area Network (WLAN), Wi-Fi, and Bluetooth, as well as mobile telephony, e.g., GSM and UMTS. Today, the term “radio” specifies the actual type of transceiver device or chip, whereas “wireless” refers to the lack of physical connections; one talks about radio transceivers, but about wireless devices and wireless sensor networks.

Mass media

“Cross-media” means the idea of distributing the same message through different media channels. A similar idea is expressed in the news industry as “convergence”. Many authors understand cross-media publishing to be the ability to publish in both print and on the web without manual conversion effort. An increasing number of wireless devices with mutually incompatible data and screen formats make it even more difficult to achieve the objective “create once, publish many”.

The primary purpose of a WIPS is to prevent unauthorized network access to local area networks and other information assets by wireless devices. These systems are typically implemented as an overlay to an existing Wireless LAN infrastructure, although they may be deployed standalone to enforce no-wireless policies within an organization. Some advanced wireless infrastructure has integrated WIPS capabilities.

Wireless Intrusion Detection System – Intrusion detection

A ‘wireless intrusion detection system’ (WIDS) monitors the radio spectrum for the presence of unauthorized, rogue access points and the use of wireless attack tools. The system monitors the radio spectrum used by wireless LANs, and immediately alerts a systems administrator whenever a rogue access point is detected. Conventionally it is achieved by comparing the MAC address of the participating wireless devices.

Wireless Intrusion Detection System – Intrusion detection

Rogue devices can Spoofing attack|spoof MAC address of an authorized network device as their own. New research uses RF fingerprint|fingerprinting approach to weed out devices with spoofed MAC addresses.
