TreeTalk Universal Wireless Communicator plus Support Panel

 

Traduzione italiana dell’autore: http://tree-talk.com/wp/comunicatore-wireless-universale-treetalk-e-pannello-push-to-talk-it/.

Universal Communicator and PTT panel are designed for unbroken real-time voice conversations between remote objects, like elevators and isolated rooms.

Based on the TreeTalk Intercom prototype, we have developed the Universal Wireless Communicator. It is designed for real-time voice conversations between remote objects, for example:

1) separated rooms, shops or offices;
2) elevators and control room;
3) mobile objects (delivery robots, unmanned vehicles) and a support service or emergency response;
4) soundproofed rooms (for example, at the box office);
5) self-service kiosks and laundromats, ATMs and customer support (dispatcher);
6) train cars and the driver.

The communicator consists of a Universal Communicator Box (UCB), which contains all the electronics (fig. 1), and a miniature panel with a Push-To-Talk button (PTT Panel, fig. 2), which can be integrated, for example, into the wall of an elevator car, as well as into an ATM or kiosk.

The Advantages of TreeTalk Universal Communicator:

1) Modular design: only a front panel, which meets the requirements for a particular use case, is publicly available. That might be a vandal-resistant metal construction for streets and elevators, or a hygienic touch-pad for hi-passability locations (ticket offices, front doors, hospitals), or a wooden or plastic decorative insert for vehicles and interior spaces. This also means that the main electronic circuit is reliably sheltered from dust, moisture and external influences in the box, which can be located covertly.
2) The communicator does not require wiring: communication with the dispatcher is via Wi-Fi and / or a cellular (wireless) network.
3) Voice communication is always on – just push a button and talk; the dispatcher program allows you to see where the signal came from and to respond instantly*.
4) If occasionally messages come from several places at once, they do not interfere with each other: the dispatcher will hear them sequentially; besides, messages can be listened a second time**.
5) Using the same program, the operator can communicate with mobile repair crews, concierges, service personnel and other staff.
6) The built-in emergency power supply of the communicator allows to maintain communication for at least 1-2 hours in the event of a power outage.

TreeTalk UCB as an Elevator Communicator.

Let’s consider the advantages of the TreeTalk Universal Communicator when used as an emergency button in the elevator car for communication with the dispatcher.

Tree Talk Elevator Communication System
Fig. 3 Tree Talk Elevator Communication System

When equipping an elevator car with a TreeTalk communicator, no additional cables are required. In the multi-storey houses built in the 50-80s of the 20th century, elevators were equipped with communication cables that run to the control room, but most of these systems are out of order and are in poor condition. In older buildings it is even more difficult to lay any new wire line. Therefore, when upgrading such elevators, the TreeTalk wireless communication device saves a lot of time and money. It is enough to fix it on the wall of the elevator car and connect the main power (Fig. 3).

Thanks to the modular design, you can use the wireless protocol that is less costly. It is recommended to use a dedicated Wi-Fi router with a directional antenna for the elevator shaft. However, if there is a reliable wireless connection in the entire building (Wi-Fi, 3G, LTE, 5G …), the network adapter can be installed directly in the Universal Communicator Box.

Changing the service company, changing the location of the concierge or security post no longer presents a problem – just transfer to a new location the computer with the dispatcher program (TreeTalk Dispatcher or Selector) and provide access to the network (fig 4).

The cost of maintaining the TreeTalk system is much lower than traditional systems, and replacing equipment in case of failure does not require special skills and is really fast. The system is configured using the convenient web interface (Fig 5). A friendly TreeTalk support team is always ready to help if something is not clear.

If the standard elevator panel is already equipped with a call button, microphone and speaker, just connect the Universal Communicator Box to it using a universal twisted cable. In this case, there is not even a need to buy a dedicated front panel.

All these advantages make obvious the choice of communicators and software by TreeTalk when installing new and maintaining existing elevator equipment.

* The technology is specifically designed to provide uninterrupted voice communications and is protected by US patent 9,338,275.

TreeTalk at Maker Faire Roma 2018 – European Edition

TreeTalk has demonstrated the working prototypes of devices, software and cloud system at Maker Faire Roma 2018 – European Edition.

TreeTalk became the finalist of the Call4Makers competition in the Innovative Projects category and presented its promising products at the Regione Lazio stand. It is a great honor for us to represent this Italian region at such a major international event.

Maker Faire is the Greatest Show on Earth in the field of invention and creativity. And Maker Faire Rome is the world’s largest Maker Faire exhibition after the “Bay Area” and “New York” in the US. Over 100,000 people participated at the biggest European innovation event in 2018.

It was an amazing 3-day event, transmitting its energy to visitors and participants. Existing companies and promising projects in various fields, such as electronics and prototyping, robotics, space, 3D printing, virtual and augmented reality were presented at dozens of thematic sites of the Nuova Fiera di Roma exhibition center.

Universities, as well as business incubators and Active Spaces (Spazio Attivo) – innovative creative platforms of Lazio Innova, represented their projects. A special place was occupied by master classes and Science Show for young people and children. And, of course, in a country where the art has long become an integral part of everyday life, particular attention was attracted by the places where art and modern high technologies together created new interesting forms.

The attention of visitors was attracted by the tireless iron (literally) rock musicians of the One Love Machine Band, playing in the open air. Amazing products, decorations, clothes and art objects from traditional materials (wood, metal, ceramics, and fabrics), but created using digital technologies, were presented.

In addition to the entertainment program, the attention of specialists was attracted by high-tech solutions in the field of Industry and Business 4.0, revolutionary solutions for the retail, agriculture, food industry, and waste processing.

It is worth saying a little about the site where the exhibition was held.
Fiera Roma was opened in April 2006 and is one of the largest and most prestigious exhibition poles in Europe. This is a great architectural work, designed by the architect Tommaso Valle, and this is an excellent futuristic business center. The center is powered by the largest thin-film solar system in Italy, covering about 38,000 square meters of the pavilion roofs. The system generates 1.8 million kWh of clean energy per year.

In addition, Fiera Roma is a center for international trade and communications. Rome is not only a world-famous tourist destination but also a very important business center, strategically located in the midst of economic flows between north and south Italy and Europe. It is a bridge between old and new markets, equipped with modern and functional structures. The exhibition center is part of a multifunctional retail and office district with an area of more than 390,000 square meters.

Fiera di Roma is situated in a strategic location and is served by an excellent transport network. In addition to roads with convenient parking and interchanges, the complex has its own suburban railway platform (2 stops from the Fiumicino international airport or several stops from the center of Rome). At the time of the Maker Faire exhibition, the Italian railways not only increased the number of trains but also organized an information point on the platform with multilingual staff helping visitors to buy tickets and understand the routes.

TreeTalk presented its promising developments at the exhibition. Those are the real-time voice communication devices: the prototype of the car voice communicator “The Terminal One” and the prototype of the stationary communicator “TreeTalk Intercom“. Also were demonstrated: a prototype of a user web interface for managing devices and their groups (TreeTalk Web Panel) and a prototype program for the PC TreeTalk Dispatcher, which combines the functionality of personnel task management and instant communication with a specific employee (selective call) or with the whole team (group call).

We are grateful to the jury of the Call4Makers contest for the high appreciation of our developments and the opportunity provided. Thanks to participation in the exhibition, we were able to acquaint many people with our developments and get extremely useful feedback that will allow us to improve our prospective products.

TreeTalk: The Terminal One – Field Tests 2018. Summer. Hot Summer.

TreeTalk Terminal
TreeTalk Terminal

Moving to the other city to the other country and is very time consuming. And, of course, is exciting. Especially if “the other city” is the Eternal City. Any movement is also distracting, but we are strong 🙂 So, despite the traditional Italian vacation time, we are trying to work. August is hot this year, and people run to the seaside. But we are already here and ready to take full advantage of the ardent heat.

If you can remember, once upon a time, we tested our very first prototype in the really harsh conditions of Siberian winter. Now we have reincarnMeteoStation_48ation number 3 of that prototype, and it’s time to trial it under the Southern sun. The conditions appear harsh enough, too, but in the opposite sense. The terminal was subject to temperature extremes up to +55 Celsius (131 Fahrenheit). The temperature inside the black metallic enclosure was 10-20 degrees more. During the test time, the built-in audit system recorded the slightest failures in the network connection, in the electronics and embedded firmware.

We have got a lot of data, most of which we still have to process, but we have first interesting results.

Spoiler: most of the tests completed successfully, clearly confirming the advantages of the TreeTalk terminal over conventional and trunked radios in the reliability and quality of the voice and in the convenience of handling.

Contrary to expectations, the extreme heat itself did not effect electronics much. But we could mark, thanks to specific environments, two peculiarities.

First one is an unstable data transfer speed of the local mobile carrier. Despite the fact that the signal almost did not disappear anywhere at all, the real data transfer speed varied in the wider range, then we use to see earlier, and the frequency switched from 3g to 4g and back more often. Perhaps, this effect is tied to uneven distribution of tourists (and their smart phones). Fortunately, our specially developed protocol, and speech-compression technology was made for working in low-speed second-generation networks. So, “LTE tourist challenge” was not a problem for our device.

RomeAlso, we found, that stability of geo-positioning was not as good as always in the narrow streets and small squares of the old Rome center. Sometimes, the majority of satellites became invisible to the GPS antenna, and precision of geo-positioning deteriorated. It seems to me, we finally unraveled the reason for the mysterious disappearances and quantum leaps of Roman buses on the maps of transport applications 🙂

Quite seriously, we anticipated this issue and evident solution will be to try using the geo-positioning chips that have real-time multi-system tuner, instead of a multi – system tuner, working in the switching mode. Perhaps, we should also slightly tune the predictive algorithm in order to make it more intelligent in the such cases. All these improvements will be done in the next version of the hardware. We hope that the next version of the terminal will be even more robust.

 

TreeTalk is moving to Rome!

Rome

Great news!
As you could see in our Twitter blog, in the end of 2017 our startup TreeTalk was selected for the Italia Startup Visa program by the Italian Ministry of Economic Development, and finally we are in the Eternal City!

Somebody could ask “Why Italy? Your startup is not about agrifood, hospitality, what else Italy famous for… Why not Silicon Valley or, maybe, Singapore?”

We have the short answer – because we love Italy!

And we have a long answer – do you know that Italian Republic is one of the European manufacturing leaders? That it is, at the same time, a big market itself and a part of the huge border-less European market, which is larger than US market? Do you know that EU has trade agreements with Canada and Japan, to name a few?

On the other hand, TreeTalk is moving closer and closer to start of production. And our B2B products can find their niche it the agrifood, hospitality, transportation – wherever the professionals need reliable, convenient real-time voice communications. That’s why we trust in this mutually profitable and long-term union.

Field Tests – 2016. Winter.

TreeTalk has conducted regular field tests of the voice terminal prototype.

The terminal is designed for professional control room and group real time communications. In fact, this is a new class of mobile devices, in which the traditional strengths of radio communication (instant connection, broadcasting and simplicity) were coupled with the advantages of modern data networks. The voice signal is digitized, compressed, and transmitted by the Terminal to other similar devices and dispatching computers without loss of quality. Thanks to a specially developed protocol, even low-speed second-generation network, covering 90% of the world population may be used as a transport medium.

The methodology of the current test was designed to assess the stability of the device and firmware in real operating conditions.
Within 14 days the equipment was tested around the clock in the laboratory. After that, withinIMG_2611_600 7 days the experimental model of the terminal was working in a car that was moving around the city and nearby suburbs in a mode of normal use. Thus, during parking, warm-up and on the move the terminal subjected to temperature extremes from -30 to +20 Celsius (-22 to +68 Fahrenheit). All this time, built-in audit system was recording the slightest failures in the network connection, the electronics and embedded firmware.
Then, a mobile measuring and laboratory benches were installed and the parameters of the speech signal were measured (in particular, the signal-to-noise ratio and frequency response), which describe the intelligibility and voice recognition when it is transferred from the terminal to other terminals or to the control room computer.

Current testing has been specially planned for the winter period and held in harsh conditions. However, most of the tests completed successfully, clearly confirming the advantages of the TreeTalk terminal  in the reliability and quality of the voice, and the convenience of handling over conventional and trunked radios.
20160129_120613_720
Users of TT terminals do not need to spend time and effort to obtain radio frequencies, search for a suitable location for the control tower and to install bulky antennas. It will be sufficient to purchase the required number of terminals and combine them into a virtual channel via a simple web interface to start using. TreeTalk LLC specialists believe that their technology, due to the convenience, the digital signal quality and additional features, will soon replace the obsolete analogue radio and will be used wherever you need a reliable, constant and instant voice communication.
