Fast connection

 By: Arfan
Modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such as carrier signals to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used for any means of transmitting analog signals, from driven diodes to radio.

The most familiar example is a voice band modem that converts digital data from personal computers to electrical signals modulated in the frequency range of voice telephone lines. These signals can be transmitted through telephone lines and modems demodulated by the other on the receiver side to recover digital data.

Modems are generally classified by the amount of data they can send in units of time, usually measured in bits per second (bit / s, or bps). They can also be classified by the symbol rate is measured in baud, how many times the modem signal state changes per second. For example, ITU V.21 standard used audio frequency-shift keying, tone alias, to carry 300 bits / s using a 300 baud, while the original standard allowed ITU V.22 1200 bit / s with 600 baud using phase shift keying.

Of the many variants of existing modems, are very difficult to be able to determine the best. From the many types of modem I use Huawei E220 modem (HSDPA USB MODEM). This modem HUAWEI TECHNOLOGIES CO. created by., LTD.
