Definitions
- the present invention relates to a method and also to a device for disabling the use of cellular phones within a predetermined confined area.
- Cellular phones which have come into wide spread use, frequently
- An object of the present invention is to provide a method, and also a device, for disabling the use of cellular phones within specified confined areas without depending on the user to turn-off the cellular phone.
- the service band refers to a specific band of frequencies used by the
- the service band can appear as any band in the cellular system. Sometimes on a separate channel and sometimes in a receptions channel. It is
- the subscriber jointly used by all the cell sites in the network to inform a subscriber which speech channel is to receive the call.
- the subscriber also uses the service band frequencies to indicate the ready status of the phone to receive a call, and to indicate the power of the signal in the respective cell site.
- connection has been made in the restricted area, and will not interfere with telephone conversations that have already started to take place before the blocking device has been activated (in most cases). Accordingly, there will be
- the power level of the jamming signal is from 0.5 to 10 milliwatts, preferably about 1.0 milliwatt. This value could also change in the future.
- a small portable housing including a voltage controlled oscillator controlled to vary the frequency of a jamming signal; a low frequency oscillator
- the foregoing method and device may be used for automatically disabling cellular phones within a confined
- the disabling of the cellular phones is effected automatically and does not require any particular act by the carrier of the cellular phone.
- FIG. 1 schematically illustrates a cellular phone and a device constructed in accordance with the present invention for disabling the use of such a cellular phone within a confined area;
- Fig. 2 is a block diagram illustrating the electrical circuitry in one form of disabling device constructed in accordance with the present invention.
- the cellular phone 2 illustrated in Fig. 1 is of a commonly-used type. It includes a small portable housing 3 having an ear piece 4 disposed in
- a keyboard 6 containing depressable number and control
- the broadcast band and the receiver band constitute most of the 800-960 MHz band width, with the service band being about 870-960 MHz.
- the service band is about 870-960 MHz.
- one system operates at 870-890 MHz, and another at 920-960 MHz.
- Such cellular telephones generally transmit at power levels of about 600-700 milliwatts.
- a device for disabling the use of a cellular phone within a
- the confined area such as a room, hall, vehicle or the like.
- the confined area such as a room, hall, vehicle or the like.
- portable disabling device 10 is physically placed in the confined area to be neutralized. It continuously transmits a jamming signal continuously varying in frequency to cover the service band spectrum for the respective cellular sites, and of a power level to have a range sufficiently only for covering the respective confined area.
- the frequency of the jamming signal is continuously varied in specific frequencies from about 800 to 980 MHz so as to cover the service band or the respective cell site.
- the jamming signal is preferably about 0.5 to 10 milliwatts. This is usually
- the power level of the jamming or disabling signal is about 1.0 milliwatts. This power level which is two or three orders of magnitude below the 600-700 milliwatts transmitted by the cellular telephones, would normally not require FCC approval nor is it likely to
- the disabling device 10 illustrated in Fig. 1 includes a housing 11 which
- the illustrated device includes an on/off switch 12, an LED indicator 13 indicating when the unit is operating, a manual range setting control 14 for setting the range of the device, a sweep frequency control 15 permitting manual setting of the lower frequency and the upper frequency of the jamming signal, and a manual control 16 for presetting the sweep frequency repetition rate of the jamming signal.
- Unit 10 illustrated in Fig. 1 further includes a display 17 for displaying the
- the signal strength of the cellular telephone system signal received in the respective area of the cell site depends on the location of the confined area to be neutralized, and also the prevailing weather
- the jamming signal to assure that it is sufficient for disabling only the cellular phones in the respective confined area where the unit 10 is located.
- disabling unit 10 includes a voltage controlled oscillator 20 which generates the jamming signal at a frequency controlled by a low frequency oscillator 21 , and a power amplifier 22 which amplifies the jamming signal and transmits it into the
- the frequency of the jamming signal generated by the voltage controlled oscillator 20 is preset by the manual frequency setting 15, and the sweep frequency repetition rate is controlled by the low frequency
- the transmitter jamming signal may be preset by manual control 14; alternatively, it may be automatically controlled by the signal strength detector 23 which detects and measures the signal strength of the cellular telephone system at the respective confined area, displays it in display 17, and automatically controls the power amplifier 22 via the range setting circuit 24. Since the signal strength detector 23 cannot operate at the same time that the disabling unit 10 transmits the jamming signal, detector 23 may be in the form of a separate unit providing a reading of the detected signal strength, enabling the user to manually preset the power setting (24) of the disabling unit. Disabling unit 10 is preferably in the form of a small, portable,
- the disabling unit can be built in the form of a synthesized oscillator in which the frequencies are controlled by a crystal in a phased locket loop (PLL) system to prevent problems in manual adjustment of the frequency or in its stabilization with respect to time, temperature, different voltages, different
- the system could use a programmable attenuator to
