Hertz (Hz)

A measurement of the number of wave oscillations within a specific time identified using the unit Hertz (Hz), or oscillations per second. Radio waves have a frequency between 3 Hz and 300 GHz. The rate at which an electromagnetic waveform alternates, usually measured in Hertz.

One of several technologies used to separate multiple conversation transmissions over a finite frequency allocation of throughtheair bandwidth. TDMA is used to allocate a discrete amount of frequency bandwidth to each user in order to permit many simultaneous conversations. However, each caller is assigned a specific time slot for transmission.

A feature/benefit provided by service providers that allows clients to consume more bandwidth when needed and if the carrier network has the capacity. Such consumption is often charged at a much higher rate.

A means or method of communication that occurs over multiple frequencies at the same time. Telecommunications techniques in which a signal is transmitted in a bandwidth considerably greater than the frequency content of the original information. Frequency hopping, direct sequence spreading, time scrambling, and combinations of these techniques are forms of spread spectrum.

FDMA is the allocation of specific channels within a defined radio frequency bandwidth to carry a specific user’s information. FDMA is a mature, reliable method of RF communication, but requires more spectrum than competing technologies to deliver its payload.
