high-power transmitter and communicates via a transceiver with a
local cellularized base station. As depicted in figure 3a, the
receiver demodulates the received data signal and provides the
result to a central processing unit (specification, page 12). A
second communication link is established with a local base
station for a two-way communication using the same frequency for
both transmitting and receiving data (specification, page 14).
Representative independent claim 1 is reproduced below:
1. A personal mobile terminal comprising:
a receiver for receiving a first data signal modulated
by a first carrier frequency;
a transceiver for transmitting a second data signal
modulated by a second carrier frequency and for receiving a
third data signal modulated by said second carrier
frequency; and
a central processing unit for controlling operations of
said personal mobile terminal in accordance with a
predetermined protocol, in which said personal mobile
terminal receives a notification message at said receiver
and, upon receiving said notification messages, initiates
two-way data communication using said transceiver.
