Description

Personal information terminal using wireless call signal

The present invention relates to a personal information terminal using a wireless call signal.

More specifically, by using a wireless call system that is currently operating and a personal information terminal capable of receiving a wireless call signal, various types of information such as large data, graphics, still images, and voices can be received and used on its own large display and external peripheral devices. It relates to a personal information terminal using a radio call signal to output.

In general, wireless calling refers to providing a service such as a beep, a number, and a letter to a specific person (subscriber) carrying a wireless call receiver (beep) as a kind of mobile communication method.

The wireless wireless terminal is used to call people on the move. The initial wireless call only generated the ringing tone, but it has been further developed and is rapidly changing from text display such as phone number to text service. And life information services such as sports events.

In addition, it is not only able to make urgent contact by using voicemail, but also is designed to transmit high-speed transmission and various information in terms of system, and it is possible to know the position of the person who has beep due to the appearance of two-way wireless wireless terminal. Way is being introduced.

In addition to wireless wireless terminals, mobile communication devices include a beeper with a calling function such as a public payphone and a mobile phone (CT-2) complementary to each other, and is a common frequency communication device used for taxi calls or truck logistics. (TRS), a mobile phone that is used by the general public regardless of the place, and a personal mobile communication (PCS) capable of transmitting multimedia such as voice, data, and video.

Among the kinds of mobile communication devices, the wireless wireless terminal (beep beep) is a relatively simpler system than other mobile communication systems, and has a relatively excellent reception rate compared to the low usage fee, and has the characteristics of being able to receive calls without being disturbed while doing other work. have.

The biggest advantage is that the pager (Beeper) is small and the service fee is lower than other mobile communication means.

However, the current wireless wireless terminal cannot receive long sentences data due to the limitation of the storage capacity and display space in accordance with the miniaturization of the device itself in receiving information, so it is possible to use only limited letters and numbers, voice and video, etc. In order to receive a separate additional system has to be installed, so a large amount of new investment in the facility, there was a problem that the cost increases.

Therefore, an object of the present invention is to receive a large amount of data, graphics, still images, and voice information using a wireless call system and a personal information terminal capable of receiving a wireless call signal. Its purpose is to connect with peripheral devices and provide various information.
