Abstract
A paging system separately transmits high capacity data through at least two paging channels of limited transmission rates in order to provide the high capacity data in real-time. A pager receives and processes the paging frequency signal transmitted through at least two channels, thereby generating regenerated data not to be separated.
Claims8
An apparatus for receiving data separately transmitted through N channels, N being a positive integer larger than one, each of which occupies a frequency band separated from one another, comprising:
- antenna for receiving a paging frequency signal from the N channels;
- N signal processing means, coupled with the antenna, for detecting N separated data from the paging frequency signal;
- means for synthesizing the N separated data detected from the N signal processing means to regenerate data, from which the N separated data are generated;
- and
- means for presenting the regenerated data thereon.
A method for separately transmitting and receiving data through N channels, N being a positive integer larger than one, each of which occupies a frequency band separated from one another, which comprises the steps of:
- separating the data into N separated data and encoding the N separated data, wherein each of the encoded data is modulated into a paging frequency signal corresponding to one of the N channels;
- transmitting the paging frequency signal through the N channels;
- receiving the paging frequency signal transmitted through the N channels;
- detecting the N separated data from the received paging frequency signal;
- synthesizing the N separated data to regenerate data, from which the N separated data are generated;
- and
- presenting the regenerated data.
