. Paging
is carried out through the Personal Radio Call Network. It applies only one channel
for servicing thousands of users. The first pagers

appeared in the late 1950s. They
were one-way communication devices provided with standard receivers. Since
1994 the device has been improved. It was provided with a low-power transmitter.
So at present the pager is able both to receive a message and to answer it. Modern
pagers may be of tone, voice, numeric and alphabetic-numeric

types. Today about
30 million people all over the world use pagers in cases of urgent transmission of
messages. It is desirable that pagers should be widely used in private life as well.
