Q2854
where is modem on WAN radio internet?
Modem
A modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information , and also demodulates such a carrier signal to decode the transmitted information.
00
Q2854
where is modem on WAN radio internet?
Modem
The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data.
00
Q2854
where is modem on WAN radio internet?

00
Q2854
where is modem on WAN radio internet?
Modem
Modems are generally classified by the amount of data they can send in a given unit of time , usually expressed in bits per second (bit/s, or bps), or bytes per second (B/s).
00
Q2854
where is modem on WAN radio internet?
Modem
Modems can alternatively be classified by their symbol rate , measured in baud .

The baud unit denotes symbols per second, or the number of times per second the modem sends a new signal.
00
Q2854
where is modem on WAN radio internet?
Modem
For example, the ITU V.21 standard used audio frequency shift keying with two possible frequencies corresponding to two distinct symbols (or one bit per symbol), to carry 300 bits per second using 300 baud.
00
Q2854
where is modem on WAN radio internet?
