Term structured wireless-aware network (SWAN) Definition A technology that incorporates a WLAN into a wired wide-area network (WAN). SWAN technology can enable an existing wired network to serve hundreds of users, organizations, corporations, or agencies over a large geographic area. A SWAN is said to be scalable, secure, and reliable. secure copy (SCP) transponder Secured encrypted command to copy files across an ssh connection, Files can be copied from or to a remote server, and also from one remote server to another. A wireless communications, monitoring, or control device that picks up and automatically responds to an incoming signal. The term is a contraction of the words transmitter and responder. Transponders can be either passive or active. ultra high frequency (UHF) International Telecommunication Union (ITU) band 9, 300-3000 MHz, 1m - 100 mm frequency wavelength. ultra wideband (UVB) Is a wireless technology for transmitting large amounts of digital data over a wide spectrum of frequency bands with very low power for a short distance. Ultra wideband broadcasts very precisely timed digital pulses on a carrier signal across a very wide spectrum (number of frequency channels) at the same time. UWB can carry a huge amount of data over a distance up to 230 feet at very low power (less than 0.5 milliwatts), and has the ability to carry signals through doors and other obstacles that tend to reflect signals at more limited bandwidths and a higher power. virtual private network (VPN) A network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization's network. A VPN ensures privacy through security procedures and tunneling protocols such as the Layer Two Tunneling Protocol ( L2TP ). Data is encrypted at the sending end and decrypted at the receiving end. voice over WLAN (VoWLAN) A method of routing telephone calls for mobile users over the Internet using the technology specified in IEEE 802.11b. Routing mobile calls over the Internet makes them free, or at least much less expensive than they would be otherwise. wideband code-division multiple access (W-CDMA) Officially known as IMT-2000 direct spread; ITU standard derived from Code-Division Multiple Access (CDMA). W-CDMA is a third-generation (3G) mobile wireless technology that promises much higher data speeds to mobile and portable wireless devices than commonly offered in today's market. Wi-Fi A term for certain types of WLANs. Wi-Fi can apply to products that use any 802.11 standard. Wi-Fi has gained acceptance in many businesses, agencies, schools, and homes as an alternative to a wired LAN. Many airports, hotels, and fast-food facilities offer public access to Wi-Fi networks. 1173 | Acronyms and Terms Dell Networking W-Series ArubaOS 6.4.x | User Guide
