Chapter 5 - Appendix Glossary Access Point (AP) A networking device that seamlessly connects wired and wireless networks. Access Points combined with a distributed system support the creation of multiple radio cells that enable roaming throughout a facility. Ad Hoc A wireless network composed solely of stations within mutual communication range of each other (no Access Point). AES(Advance Encryption Standard) AES is the U.S. government's next-generation cryptography algorithm, which will replace DES and 3DES. This encryption key protocol is applied in 802.1i standard to improve WLAN security. AES will require new hardware, in contrast with TKIP that can be used on existing wireless devices. Basic Service Area (BSS) A set of stations controlled by a single coordination function. Broadband A type of data transmission in which a single medium (such as cable) carries several channels of data at once. Channel An instance of medium use for the purpose of passing protocol data units that may be used simultaneously, in the same volume of space, with other instances of medium use (on other channels) by other instances of the same physical layer, with an acceptably low frame error ratio due to mutual interference. Client A client is the desktop or mobile PC that is connected to your network. COFDM (for 802.11a or 802.11g) Signal power alone is not enough to maintain 802.11b-like distances in an 802.11a/g environment. To compensate, a new physical-layer encoding technology was designed that departs from the traditional direct-sequence technology being deployed today. This technology is called COFDM (coded OFDM). COFDM was developed specifically for indoor wireless use and offers performance much superior to that of spread-spectrum solutions. COFDM works by breaking one high-speed data carrier into several 5.
