Definitions

  • the invention relates to a mobile radio unit with a handheld radio.
  • Such small and handy hand-held walkie-talkies so-called cell phones, which also have a low weight, can be operated wherever there is a corresponding network.
  • the transmission power of known cell phones is 1 or 2 W.
  • a disadvantage of these hand-held radios is, on the one hand, their low transmission power, which limits the possible uses of the cell phones, which is particularly true when used in the vehicle interior, where the transmission and reception quality - as well as the network stability. Also occur when using a walkie-talkie in
  • portable radio devices so-called portraits
  • the transmission power is between 5 and 8 W.
  • their area of use is significantly larger than that of hand-held radio devices. Since they also have larger batteries, their standby and operating time is also considerably longer.
  • the electromagnetic influence of a user is also less than that of handheld radio devices, since their antennas are not arranged on the handset. It is disadvantageous that these large and heavy portable versions of mobile telephones are used everywhere, even outside of vehicles, but their use in the vehicle is restricted. In addition, because of their size and their greater weight, they are bulky compared to hand-held walkie-talkies.
  • car telephones with a transmission power of 8 W are known, the high transmission power of which enables a wide range of uses. Since the car telephones have hands-free devices and are installed in the vehicle, they also have the necessary safety and a high level of user comfort due to the hands-free speaking.
  • the antenna is located outside the vehicle so that there is no electromagnetic interference on the user. There are also no operational and standby restrictions as with the portable versions.
  • a disadvantage of car telephones is that the user can only be reached inside the vehicle. It is not possible to change vehicles. In addition, the installation of a car phone is cumbersome and expensive.
  • the invention is therefore based on the object of providing a mobile radio unit of the type mentioned at the outset which is easy to use both outside and inside vehicles with a high level of security and in which, particularly when used in the vehicle, the electromagnetic load on the user in the head region despite high Transmit power is reduced.
  • a mobile radio unit with a handheld radio which can be connected to a portable receiver and transmitter which can be actively connected to the handheld radio and an antenna separate from the handheld radio and is in the form of a slide-in housing and an antenna amplifier to increase the transmission power of the Handheld radio device, is characterized.
  • an already existing handheld radio or cell phone can be used. This cell phone becomes active when you get into the vehicle connected to the receiving and transmitting device and you can make calls as usual with your mobile phone. Due to the antenna amplifier, however, there is now an increased transmission power, preferably in the range of more than 5 W, in particular approximately 8 W, which corresponds to that of a "real" car telephone.
  • the handheld radio Because the handheld radio is connected to a separate antenna, there is no electromagnetic interference in the head area of the user. Since the receiving and transmitting device is designed in the form of a slide-in housing, it can be simply inserted into corresponding receiving devices, so that loose cables no longer interfere with the interior of the vehicle. When leaving the vehicle, the hand-held radio or cell phone can then be detached from the receiving and transmitting device or the entire device can be removed, so that theft is excluded from the vehicle.
  • the call number and the network authorization are coupled to the hand-held radio device, passengers can also connect their cell phones to the receiving and transmitting device, in which case only their hand-held radio device is charged.
  • the handheld radio is simply changed so that the respective driver can be reached via his own number and his own cell phone.
  • a telephone adapter connected to the receiving and transmitting device is preferably provided for connecting the portable radio device.
  • This telephone adapter is preferably in the form of a Bracket trained.
  • the hand-held radio device can be inserted into the telephone adapter when entering the vehicle, which means that a handset is now available, such as a car telephone or a portable radio device.
  • the handheld radio can be removed from the telephone adapter.
  • the telephone adapter can either be connected with a handset cord or wirelessly with the slide-in housing. On the one hand, this provides full mobility like a cell phone, and on the other hand it offers comfort, security and reception quality like a car phone.
  • the active holder for the handheld radio can be locked inside the vehicle, preferably on the front plate of the slide-in housing. This means that the handset is always easily accessible to the user.
  • the receiver and transmitter have a hands-free device.
  • the electronics required for hands-free calling are contained in the receiving and transmitting device. Since the slide-in housing can be inserted into a corresponding stationary receiving device, for example the radio slot in the console area, the car telephone created in this way is easy to operate, and hands-free operation for switching, steering etc. remains free during hands-free calling.
  • At least one microphone, at least as part of an acoustoelectric hands-free unit, is preferably provided on the front panel. In hands-free mode, the microphone is not too far away from the caller when using the car radio installation slot, so that communication is not impaired by too great a distance.
  • the existing connections in the radio shaft such as power supply connections, antenna connections and connections for the car speakers, can be used. Accordingly, the existing vehicle speakers can then be used for hands-free calling.
  • the hands-free operation is carried out in full duplex, as in the normal telephone. If necessary, for example when driving noises etc. are too high, calls can be made using the handset that can be locked on the front panel.
  • the slide-in housing has a radio receiver part. In this way, no further or separate installation slot for the car radio is necessary.
  • a portable receiving device is provided for the slide-in housing.
  • This is preferably in the form of a case part.
