Description

An apparatus for wireless communication with a mobile phone

The invention relates to a device for wireless communication with a a speech handset having cellphone and having a transmission and Empfangseinrich- processing.

In most hand-talkies for wireless communication is small and handy walkie-talkies, so-called mobile phones, which have a low weight and can be operated wherever an appropriate "network exists. The transmit power of known phones is 1 and 2 respectively. The disadvantage of these walkie talkies on the one hand is the low transmission power by which the applications of mobile phones is restricted, which is especially true when using inside the vehicle, where the transmission and reception quality and network stability can be desired. Furthermore occur with use of such a hand-way radio by the radiated from the antenna and received electromagnetic waves in the radio wave range, which serve as a carrier for the modulated audio signals, interference that both a physical impairment of the user (for example, influence on a pacemaker) and when used in the interior of the vehicle for technical faults on the motor vehicle, for example, the on-board electronics, the airbag etc., may be responsible. The same applies when used in aircraft. is is stung of the hand voice radio appliance, the greater the high-frequency radiation or electromagnetic interference in the head region of the user, damage to health can not be excluded by their frequent exposure - the greater the Sendelei.

Should such a walkie talkie to improve reception example, be connected to the external antenna of the vehicle so loosely hanging cables are necessary inside the vehicle.

Further, portable radios, so-called portioning tables are known that are characterized by a better transmission and reception power as mobile phones, the transmitting power is between 5 to 8 watts, distinguished. This makes their use area is indeed much greater than that of walkie talkies and electromagnetic interference of a user over that by hand-held radio telephone is lower because their antennas are not arranged on the handset, however, their use in the vehicle is limited, because they large and heavy portable versions of mobile telephones represent. While you can find to use everywhere, but are walkie devices due to their size and greater weight over manual unwieldy.

Finally, car telephones with a transmitting power of 8 watts are specially known for use in vehicles whose high power allows a wide range of applications. The antenna of such car telephones located outside of the vehicle, so that the user no electromagnetic interference is present. And standby limitations as with the portable versions are also not available. However, a disadvantage here that the user is available only within the vehicle. A vehicle can not be changed. In addition, the installation of a car telephone is cumbersome and costly.

The invention is therefore based on the object to provide a wireless communication apparatus of the aforementioned type which is easily usable both outside and inside of vehicles, buildings, etc. with high safety and in particular in use in the vehicle as well as in other rooms the electromagnetic load on the user is reduced in the head region in spite of high transmission power.

Preferably, this unit is arranged at the antenna of the hand opening device, especially at the tip of the antenna. In this way, it is also prevented during pulling out and pushing in the antenna of the mobile phone that damage to the unit rode. Such a mobile phone can then be used both for the trouble-free speech via the infrared transmitting and receiving unit, as well as in conventional radio operation by radiating and receiving electromagnetic waves via the antenna. In order to continue to ensure upon removal from the vehicle for an uninterrupted speech communication, the speech handset is preferably switchable between the antenna operation and infrared connection operation, wherein the switching is preferably carried out automatically as soon as the distance between the vehicle-outside antenna and transmit and receive device for an infrared compound is too large or the distance is reached to establish an infrared connection. Therefore, when leaving the vehicle, an existing connection via the infrared transmitting and receiving unit is obtained at the top of the vehicle-outside antenna main-. Upon further distance from the vehicle to automatically switch on the infrared connection to normal .Antennenbetrieb / wireless operation of the walkie device can then take place. In this way is always provided for uninterrupted voice traffic, both when leaving the vehicle as well as when entering into the vehicle. Outside the vehicle, a normal speech communication via the antenna of the handheld radio communication device is possible. Within the vehicle this is done by way of advanta- via the infrared connection by means of infrared transmitting and receiving units on the handset as well as the receiving and transmitting device in the vehicle. Accordingly, no interfering electromagnetic radiation occurs in the operation within the vehicle and in close proximity to the vehicle.
