INTRODUCTION
Multimedia content influences everything today. It fulfills our basic needs and also enables human interaction in unprecedented ways. This multimedia data can be created very fast, experienced even faster but transferring it as fast remains a major hindrance. Every device has some advantage. Some are better at creating content. Others are better at playing back content. Still others fulfill both roles in a portable platform. The ability to share content between devices is necessary to bridge the two worlds thus enhancing the enjoyment and value of individual devices. But its complexity does not allow people to fully enjoy this. Still, many people successfully navigate the existing procedure though other opportunities exist for sharing content. TransferJet Flash Drive solves the content sharing problem in a way that also achieves high performance, high security and extreme ease by using the TransferJet Technology at a low cost.
TransferJet enables high speed transfer between two electronic products. A user can push any data file from her/his mobile terminal to another mobile/stationary terminal just by touching. Alternatively, the user can get any data file from another mobile/stationary terminal with a similar touch operation. Once connected, one can access, retrieve, manage, and execute any files on the mobile terminal in the same way as local files. The user can play back and enjoy streamed contents on the host terminal having a high resolution display and a high quality surround sound, without any physical cable connection.
TransferJet mainly supports two major existing protocols: OBEX and SCSI. By adopting these two well-defined and mature protocols, it is possible to incorporate TransferJet into a variety of commercial products, services, and applications. The features of TransferJet greatly enhance the simplicity of the system. The short range makes it possible to operate in the near field of the radio signal using very little transmit power. The point-to-point topology simplifies the network setup and management procedures, minimizing power consumption. The devices do not have to be precisely oriented to achieve a good connection. The spectrum is centered at 4.48 GHz, and occupies a bandwidth of 560 MHz The choice of this spectrum, coupled with the extremely low transmitting power, enables unlicensed operation in most regulatory domains. Each TransferJet device can detect the presence of another device as it comes within range. It is possible to save power by transmitting only when another device is detected. Since TransferJet communicates using a radio signal, it must comply with government regulations in any geographic region in which it operates. The TransferJet Flash Drive uses this TransferJet technology to perform the functions of a USB Flash Drive only at a higher speed increasing the efficiency of data transfer. The TransferJet Flash Drive can be used to extract data, store data and even export it by all other non-TransferJet supporting devices.
TECHNOLOGY DEVELOPMENT
TransferJet™ is a new wireless technology that combines the speed of UWB (Ultra-Wide Band) with the ease of NFC (Near Field Communications). By doing so, TransferJet™ delivers a transfer speed of 560 Mbps available to the end user through a simple “touch”. The key concept of TransferJet™ is this “touch” model of user operation. This model requires only a simple touch motion from the user to make things happen. Touch is such a natural motion that people tend to “get it” very quickly. Clearly, touch is a very natural and intuitive motion. From a user standpoint, TransferJet™ can be thought of as a universal touch-activated interface which instantly connects a wide variety of consumer (and non-consumer) electronic products. The TransferJet™ technical specifications have been developed in order to realize simplicity of use based on the “touch” model. The unique qualities of TransferJet™ make it useful for many applications. TransferJet™ can transfer data at a peak speed of 560 Mbps, with an effective throughput up to 375 Mbps. The maximum range of operation is on the order of a few centimeters and the network topology is always point-to-point between two active (powered) devices. These last two features greatly enhance the simplicity of the system. The short range makes it possible to operate in the near field of the radio signal using very little transmit power – at or below -70 dBm/MHz.
The point-to-point topology simplifies the network setup and management procedures. And since the near field is a non-polarized field, the two devices do not have to be precisely oriented to achieve a good connection. The spectrum is centered at 4.48 GHz, and occupies a bandwidth of 560 MHz. The choice of this spectrum, coupled with the extremely low transmit power, enables unlicensed operation in Japan, US, the EU, South Korea and other regulatory domains. In addition, TransferJet™ contains a robust protocol which includes error detection and correction, packet acknowledgement, and packet resend. All of these details work together to minimize complexity and interference. The low transmit power and point-to-point topology help to minimize power consumption. Finally, each TransferJet™ device can detect the presence of another device as it comes within range. Therefore, it is possible to save power by transmitting only when another device is detected. This is another advantage of the touch model.
Technical Implementation
In order to realize the initial reference use cases, the TransferJet Consortium decided to support two major existing protocols: OBEX (abbreviation of OBject EXchange, also termed IrOBEX) and SCSI (abbreviation of Small Computer System Interface). By adopting these two well-defined and mature protocols, it is possible to incorporate TransferJet™ into a variety of commercial products, services, and applications.
After technical review, the consortium concluded that all initial reference use cases can be implemented by leveraging these two protocols. The file exchange is realized by utilizing the OBEX Inbox Service. The OBEX Folder Browsing Service and SCSI support the file access functions. SCSI is suitable for implementing the real time content consumption services. Print services can be achieved by using either OBEX or SCSI. In conclusion, TransferJet™ 1.0 supports specific profiles of OBEX and SCSI.
FEATURES
3.1 "Touch&Get"interface
Just touch two electronic products together and files are transferred automatically. Transfer Jet eliminates the complex setup procedures required by existing wireless systems, and no access point is necessary. Users are also able to register their electronic products to enable Transfer Jet to recognize specific products. Operation is also very intuitive, and as there is no host/target relationship, data transfer can take place between mobile phones and PCs.
3.2 Safe and Flexible
Transfer Jet has the capability of identifying the unique MAC addresses of individual devices, enabling users to choose which devices can establish a connection. By allowing only devices inside the household, for example, one can prevent data theft from strangers while riding a crowded train. If, on the other hand, one wishes to connect the device with any other device at a party, this can be done by simply disabling the filtering function.
Transfer Jet uses the same frequency spectrum as UWB, but occupies only a section of this band available as a common worldwide channel. Since the RF power is kept under -70 dBm /MHz, it can operate in the same manner as that of UWB devices equipped with DAA functionality.
BLOCK DIAGRAM
A TransferJet flash drive should consist of a small printed circuit board carrying the circuit elements, a TransferJet Coupler, a decoder and Flash memory, all insulated electrically and protected inside a plastic, metal, or rubberized case which can be carried in a pocket or on a key chain, for example Flash memory stores information in an array of memory cells made from floating-gate transistors.
The TransferJet Flash Drive is also designed to have a USB connector. The data stored in the Flash memory of the TransferJet Flash Drive can then be accessed by all other non-TransferJet supporting devices using a USB connector. The data stored in the drive can also be accessed by another device supporting TransferJet. The TransferJet Flash Drive will require a microcontroller for the encoding and decoding and sending the handshaking signals and protocols. The TransferJet Flash Drive will also need a power source. Block diagram of TransferJet flash drive is shown in fig.4.1.
CONCLUSION
TransferJet Flash Drive provides a new method of data transfer which is faster than all widely used options. With a data transfer speed of 560 Mbps, it is a better alternative than the most widely used USB 2.0 which has a maximum data transfer speed of 480 Mbit/s, it also convincingly beats its wireless counterparts-Bluetooth 2.0 (3Mbps), Wi-Fi (54Mbps) and finally the LAN which has a maximum speed of 100 Mbps apart from the obvious inconvenience caused due to the wired form of data transfer. The one to one topology makes TransferJet one of the most secure technologies available today. Combined with the unique touch feature, it makes using the TransferJet Flash Drive extremely convenient to use. The TransferJet Flash Drive serves two important purposes. It can be used as a memory storage device like a pen drive and be accessed by two TransferJet supporting devices. It is also an added accessory for current non-TransferJet compatible devices to reap the benefits of this revolutionary technology.
