Description

ANALOG AND DIGITAL COMMUNICATION SYSTEM

COMPUTER-COMMUNICATION DEVICES

The subject of the invention is a system of analog and digital communication between computer-communication devices in which a wireless transceiver operates, which, in combination with a telecommunication device, enables two-way audio and data communication on standard unlicensed radio frequencies between two identical transceivers or between transceivers. a receiver and a classic two-way radio (VValkieTalkie) operating in the same frequency band. The system according to the invention basically allows operation on radio frequencies and modulations intended for public two-way voice communication (such as PMR446, FRS, etc.), but may also use other standardized or non-standardized frequencies and modes of communication. The invention belongs to class H04L 45/00 of the International Patent Classification.

People are increasingly dependent on the use of smartphone telecommunications devices, which provide additional services beyond communication itself. Smartphones need to be connected to the mobile network and the Internet for 100% efficiency. However, the use of smartphones is not possible when the user finds himself in a location where there is no mobile telephony or the Internet, so communication between telecommunication devices is not possible.

Smartphones cover a wide range of communications over mobile telephony and the Internet. At the same time, smartphones can redirect or route the flow of data from the smartphone to the Internet or other computer and telecommunication devices through various built-in components (radio transmitter / receiver, GPS, other short-range wireless devices, communication interfaces).

Smartphones are adequately performing their communication role in an environment where all the necessary infrastructure is built - mobile telephony, short-range wireless devices or internet access. Mobile telephony operates at frequencies from 850 to 1900 MHz, short-range wireless devices operate at frequencies from 2.4 to 5.8 GHz - WIFI and Bluetooth IEEE-802.11x standard, about 2.4 GHz, GPS operates at frequencies from 1.227 to 1.575 GHz. The higher the frequency, the lower the wavelength range at the same transmit power, which means that they need infrastructure or another telecommunications device in the immediate area. These frequencies are statutory and regulated by the ITU (International Telecommunication Union).

The permissible ranges for the various components depend on the transmit power. The GSM frequency range is around 35 km, while VViFi is up to 3 km and BlueTooth is up to 100 m. All of these frequencies, however, have a fairly poor penetration power through walls and other materials, which means that by increasing barriers in the surrounding area, communication reach is reduced.

Systems such as PMR446 and FRS operate at frequencies between 400 and 500 MHz, which are also regulated by the ITU. These frequencies are publicly available and may differ from country to country in terms of transmission power and frequency steps across channels. The frequency range depends on the transmit power and the obstacles in the surrounding area. Although these frequencies have better penetration than the GSM network, the transmit power is very limited (from 0.5 W onwards), depending on the country, which means a range of 10 km forward, which in turn diminishes depending on the obstacles.

In researching other possible similar solutions, we came across a patent application from GO TENNA from the United States entitled "SYSTEM AND METHOD FOR DIGITAL COMMUNICATION BETVVEEN COMPUTING DEVICES" with patent application number "WO2015139026 (A2) - 2015-0917". GO TENNA's device is similar to ours but our device is superior or different. GO TENNA operates at frequencies lower than 151-154 MHz and our device operates at frequencies between 400 and 500 MHz, which means that our device has a greater chance of retransmitting through obstacles, while at the same time our frequency band is not limited to operating inside The United States. Our device is superior to the GO TENNA device in that it has the ability to send and receive audio, which also allows the user to communicate audio. From a technical point of view, this means that our device has other modules in place that provide communication between the telecommunication device 1 and the wireless transceiver 4 or between two wireless transceivers 2.

The technical problem that the present invention system successfully solves is wireless communication between two (or more) people without the need for special infrastructure (eg, mobile network or satellites) that would provide features similar to those offered by mobile phones today and are of particular importance where / when communication resources are limited eg. voice communication, text messaging, geolocation reporting, navigation from one user to another, emergency location reporting.

The system of analogue and digital communication between computer communication devices according to the invention contains or. enables the following operations to be performed:

two-way radio (radio-flow) technology in the form of a radio frequency module operating in radio frequency bands where licenses are not required;

a Bluetooth module that connects a two-way radio module to a smartphone, a microcontroller that monitors the operation of the device of the invention and communicates between the device of the invention and the smartphone; a fixed space for storing radio module settings, messages, location information, and emergency reporting when / if the device of the invention is not connected to a smartphone;

a custom made application (compatible with iOS and Android) that serves as the user interface for operating the device according to the invention and giving it the features of a smartphone (geolocation, input / output audio).

The object of the invention is a system of analogue and digital communication between computer-communication devices, comprising the device and the corresponding protocols for the operation of the computer-communication devices. The system implementation device consists of a pair of wireless transceivers 2 and a telecommunications device 1 that provides two-way audio and data communication on standard unlicensed radio frequencies between two identical pairs of transceivers 2 and a telecommunication device 1 or between a pair of transceivers. receiving devices 2 and telecommunication devices 1 and standard two-way radios (eg VValkieTalkie) 5 operating in the same frequency band and based on the same standard. The device operates essentially on radio frequencies and modulations intended for public two-way voice communication (such as PMR446, FRS, etc.), but may also use other standardized or non-standardized frequencies and modes of communication.

An apparatus for implementing an analogue and digital communication system between a computer-communication device according to the invention consists of two parts, namely an external radio transceiver 2, which enables the transmission and reception of sound and data at standard radio frequencies and telecommunication devices 1. The transceiver device 2 consists of processor 2a, radio component 2c, antenna 2d, memory 2e, real-time component 2f, and secondary wireless component 2b. Telecommunication device 1 consists of an audio input port 1a, an audio output interface 1b, an input-display interface (display, keypad) 1c, sensors (eg GPS, accelerometer, etc.) 1d, short-range wireless component 1e, and software 4.

Figure 7 shows a block diagram of two communicating devices according to the invention and a representation of the transmission of sound and data through the main components within the two devices, while Figure 8 shows a block diagram of the device according to the invention and the sound or data path through the main components of each devices in the system, until data is transferred from telecommunication device 1 to a web server 3.

Each transceiver 2 includes a processor component 2a for processing and controlling the operation of the other components within the transceiver 2, and the device further comprises an additional secondary wireless communication component 2b that provides two-way connection and transmission of sound and data between the transceiver device 2 and telecommunication device 1 (e.g., smartphone or tablet). The secondary wireless communication component 2b is based on short-range wireless communication technology (eg, Bluetooth, Zigbee, WiFi, IR, etc.). The telecommunication device 1 has software 4 (application), which contains a graphical interface and through which we control the transceiver device 2. The software 4 installed on the telecommunication device 1 enables the reception of sound or data through the input interfaces (built-in or external microphone as audio) input interface 1a, keyboard or touch screen as input or input 1c display or from various sensors 1d embedded in a telecommunications device capable of generating data (such as a geolocation component, accelerometer, gyroscope, etc.). or transmits the data to the transceiver 2 via a wireless link between the short-range wireless communication component embedded in the telecommunication device and the same component 2b on the transceiver 2. The sound is then transmitted from the transceiver 2b to the radio component 2c, process controlled r components 2a. However, data is transferred from the secondary wireless component 2b to the processor component 2a. The latter transmits the data forward to radio component 2c if intended to be transmitted to another transceiver via a two-way radio link, respectively. they are properly processed and triggered by the corresponding changes on the transceiver 2 contained in the data (eg change of frequency parameters of the radio component, etc.).

The radio component 2c modulates the received sound or data to the appropriate radio frequency and transmits to the surroundings in the form of a radio wave through the antenna 2d in order to receive them by another transceiver having compatible radio settings (frequency, channel width, subchannel, etc.). ) as the transceiver receiving the signal.

In the case where the transceiver 2 receives a useful signal (containing sound or data) from the surroundings via antenna 2d, it demodulates it appropriately on the radio component 2c and sends the sound directly to the secondary wireless component 2b and the data to the processor unit 2a, which processes, interprets and transmits to the secondary wireless component 2b. The latter then sends the audio or data via a wireless connection to the same wireless component 1e on the telecommunication device 1. There, under the control of software 4, the audio is output through the appropriate audio output (built-in or external)

microphone, headset, or related device) 1b and display the data appropriately on the screen of the telecommunications device (depending on the content of the data). Depending on the content and type of data, the software installed on the telecommunication device 1 allows the data to be displayed as a message or as geolocation information on a map or as an emergency alarm, etc. Software 4 also includes a graphical interface as a directory, showing all other known users of the same transceiver 2 and automatically updating information about the last known user radio settings. Telecommunication device 1 enables, through the installed software 4, the transmission of all collected data to an Internet server 3 intended for users of the transceiver 2 while the telecommunication device 1 is within range of a wireless Internet connection. The information on Internet server 3 is stored in the user's personal profile. Internet server 3 may also contain a web site for easier access to user data.

The software on the telecommunication device also enables the sending of a package of new software for the processor component of the transceiver via a short-range wireless connection. New software may be downloaded to the telecommunications device from the Internet when it has an Internet connection, or otherwise.

In addition to the processor component 2a, the secondary wireless component 2b, and the radio component 2c, the transceiver 2 also includes a memory component 2e and a component that monitors the current time even when the device is off 2f. Memory component 2e is associated with processor component 2a and is intended for storing the last settings (selected channel, subchannel, sound amplification level in both directions, etc.) for the time when the transceiver is switched off, messages received when the transceiver not connected to telecommunication device 1 (and messages cannot be directly transmitted to the software user interface 4), storage of the user's last location information (for emergency calls in case of loss of connection to the telecommunication device). The memory component can be realized in different ways (flash memory, EEPROM, etc.) or even as a combination of several different memories. Component 2f for storing real-time information is also connected to processor component 2a and is responsible for maintaining accurate time information on the transceiver 2, in particular for the timing of messages received and the last location information. The component updates the status of the exact time each time it reconnects to the telecommunications device 1 via a short-range wireless connection. The processor component 2a, the memory component 2e, and the real-time information storage component 2f may also be interconnected in the sense that several of the above functionalities are combined into a single component or that several components share the same functionality.
