Analog uses signals of continuous wave to carry information and data over radio channels. Analog carries 1 call per channel as opposed to Digital that carries 15 calls per channel. This proves digital is more sophisticated and offers clearer signal.
Early cellular phones all used analog but that is no longer the case. Today’s modern cellular phones all use digital technology. Infact, some carriers no longer offer analog service!
Analog mode offers broader coverage but less standby and talk time. It is more expensive and calls are not very secure.
Digital mode converts information into binary digits (0’s and 1’s) where 0 means off and 1 means on. Even Computer PC’s utilize this kind of memory in RAM and other types of memory.
Digital mode offers distortion and disturbance free communication between phones, unlike Analog technology. Most of the cellular phones produced today are digital and not analog.
Digital phones offer encrypted transmissions, text messages, call ID and longer battery life among other things.
PCS is a two way 1900 MHz digital wireless technology. It was introduced into North America back in 1990 and is the most widely used wireless service in North America today.
Every call made requires its own tranmission channel and this can slow down transmission of data.
Cellular technology provides two way data and voice transmission through cellular phones that are common today.
This technology is dual meaning it can send and receive data on both analog and digital modes.
This technology operates on 1800 MHz and 1900 MHz networks to send and receive data and voice. With dual band, the phone can function in digital, cellular or PCS (three most widely used communication technologies today). Look for phones with dual mode or dual band capabilities if you travel alot.
