BACKGROUND ART It is known to use a hand carried cellular or other type of phone. It is also known to use a portable pager with means for multiple pager messages and a pager display. Typical cellular phones and pagers are described in U. S. Pat. Nos.

5, 884, 188 ; 5, 933,088 ; and 5,940, 742. Also wearable hands-free computers are luiown. Hands-free computer is described in U. S. Pat. Nos. 5, 304, 244 ; and 5, 844, 824. Since phones, pagers and computers have been extensively used, it has become awkward to carry each on one person.

In European Pat. No. 0,907, 279 a mobile communicator is disclosed con- sisting of a wrist strap and an actual combined mobile communicator connected to it which has at least two separate mobile communicator parts. The parts of the mobile communicator are mechanically connected by joints so that they can be folded in against one another in repose position and can be opened profitably se- quential and parallel in usage position.

In U. S. Pat. No. 2002/0022499 a communication device is disclosed having a single unit called a personal communicator that combines the functions of a cell phone (or mobile phone), a body supported computer and a pager. The personal communicator has three detachable modules: a communication module, a display module and a core computer module. The core computer module has all of the components of a general purpose computer. Each of the modules when detached can be used in other systems such as with other screens.

In U. S. Pat. No. 6,085, 112 a communication device is disclosed having a computer with speech input and output devices combined in one structure. Pref-

erably, the computer can be removed from the device and communicate with the basic device using an infi-ared link. In addition, a broadband transmission link may be provided, radio waves which are independent of the telephone network making contact with computer servers which are preferably provided.

While some of the above patents disclose mobile phones, two-way radios, pagers and computers, the disadvantage is that none of these patents suggest the use of carried mobile structure where the computer can be connected to the radio- network without using the phone.

It is due to the fact that transmitter and receiver modules for establishing a connection to the base station is situated inside phone module. Other disadvan- tages of this structure are harmful electromagnetic field that is radiated near the head of the user, comparatively big size of the phone module and non-ergonomic use of personal computer due to small size of display and keyboard that is re- stricted by the size of the phone.

These disadvantages cause inconvenience in use of this device and harm to human health.

DISCOSURE OF INVENTION It is therefore an object of this invention to provide a mobile structure de- void of the above-noted disadvantages.

Another object of this invention is to provide convenient use of this com- mmication device.

Yet another object of this invention is to provide simultaneous use of com- puter and phone functionality of this device.

Still a further object of this invention is to decrease the power of harmful electromagnetic field that is radiated near the head oh the user without reduction of the distance of well-provided connection between the device and a base station.

Still another object of this invention is reducing the handset power con- stunption.

Yet, still a further object of this invention is significant reducing the hand- set size.

These and other objects of this invention are accomplished by a communi- cation device containing at least wireless handset and computer module, where both the handset and the computer module have transmitter and receiver to estab- lish wireless connection to each other, and the computer module has additional transmitter and receiver for connecting to the base station. Due to the fact the power of handset transmitter can be significantly reduced that results in decreas- ing of power consumption, harmful radiation and size of the handset. Wireless connection between the handset and computer module allows performing some phone functionality on the computer module and using data shared by both the handset and the computer module. For example it can be used for sharing of a da- tabase that stores phone numbers and addresses or sharing of sound records. The wireless connection also gives the opportunity to control the computer module remotely from the keypad of the handset.

Due to the fact that both the computer module and the handset have own keyboard and display they can have different embodiment. It gives the opportu- nity to satisfy user's requirements that are different for the computer and the phone.

BRIEF DESCRIPTION OF DRAWINGS FIG. l is a general view of the communication device of this invention where the handset, the computer module and wireless connections are shown ; FIG. 2 is a functional layout of the wireless handset ; FIG. 3 is a functional layout of the computer module.

BEST MODE FOR CARRYING OUT THE INVENTION A general view of the communication device of this invention is illustrated on FIG. 1. The communication device has at least one handset 1 and computer module 2, that interact with each other using wireless connection. The computer

module is connected to base station 3 via another wireless connection. The hand- set is connected to a telephone network via both wireless connections through the computer module.

In FIG. 2 functional layout of the wireless handset is illustrated. The handset has at least speech input and output devices unit 4, which is connected to signal processing unit 5, display unit 6, keypad 7, control unit 8, transmitter and receiver unit 9. Signal processing unit 5, display unit 6, keypad 7 are connected to the con- trol unit 8. Control unit 8 is connected to transmitter and receiver unit 9.

In FIG. 2 functional layout of the computer module is illustrated. The com- puter module has at least transmitter and receiver 10 for establishing wireless connection to the handset; display unit 11, keyboard 12; control unit 13, transmit- ter and receiver unit 14 to connect to a base station, central processing unit 15 and memory 16. In general the computer module can have all of the components of general purpose computer.

The preferred and optimumly preferred embodiments of the present inven- tion have been described herein and shown in the accompanying drawings to il- lustrate the underlying principles of the invention, but it is to be understood that numerous modifications and ramifications may be made without departing from the spirit and scope of this invention; for example wireless connection between the handset and the computer module can be established by radio transmission, ultrasonic or infrared link.

INDUSTRIAL APPLICABILITY Using up-to-date components for this device construction allows signifi- cantly decrease weight and size of the handset, reduce influence of harmful elec- tromagnetic field and extend distance of well-provided connection to the base sta- tion due to increasing of the transmitter power that is situated in the computer module on a distance from the user.

For example when using Bluetooth technology for wireless connection be- tween the handset and the computer module the power of handset transmitter can be reduced to 1-2 mW, that is 1500-3000 times lower then the radiation power of typical GSM-900 cell phone.

The communication device of this invention can be used for telephone communications, receiving and transmitting of messages, images, files and fac- similes, performing calculations and data processing etc. Besides that, this com- munication device can be used as an audio player-recorder or as video telephone.
