Glossary
| Access point | A transceiver or radio component in a wireless LAN that acts as the transfer point between wired and wireless signal, and vice versa. The AP is connected to antennas as well as to the wired LAN system. |
| ADSL | ADSL (Asymmetric Digital Subscriber Line) is a digital transmission process that enables data transmission rates of up to 8 Mbit/s to customers and up to 700 Kbit/s from customers via normal telephone lines. This involves digitally separating the telephone line into three channels, two for data transport and one for telephony. The system is referred to as "Asymmetric" because the upstream and downstream channels transport different amounts of data. |
| Analog | Signals that can be interpreted by humans, such as speech and music, are analog. These signals are constantly changing, for example in their pitch and acoustic pressure. In more technical terms, an analog signal is a physical factor that can adopt any value - that is, continuous interim values - within certain defined limits. Information is transmitted through the analogous (analogous = analog) pitch or frequency of the signal. The transmission is comparatively susceptible to interference. The opposite of "analog" is "digital". |
| Analog Transmission | The traditional telephone technology (for voice transmission) in which sound waves (or other data) are converted into electrical impulses of varying strength or amplitude. |
