Antenova brings TransferJet technology to CTIA Super Mobility

Antenna maker Antenova is launching a coupler using TransferJet wireless technology for the high-speed data transfer of large files. The UK company will demonstrate the system using hardware from RF design specialist Icoteq at this week’s CTIA Super Mobility show in Las Vegas.
TransferJet is a close-proximity wireless transfer standard, recently created in Japan, that provides a simple way to transfer large data files such as photos, videos and music, between mobile devices, at data rates as high as 375Mbits/s, simply by placing the devices close together. It has the advantage of operating in unlicensed bands in the USA, Japan, Korea and EU countries.
Antenova’s TransferJet system uses an SMD coupler, called Zoma (part number SR4TO14), which the company has developed to be an RF coupler for TransferJet. The coupler operates in the 4.48GHz band, and transfers data over distances up to 30mm.
Antenova has chosen to work with a TransferJet development platform from fellow UK company Icoteq, and visitors to CTIA Super Mobility will be able to see this operating with the Zoma antenna. Icoteq’s hardware uses Freescale’s iMX6 quad core processor, comes with a variety of hardware interfaces, and measures 100 by 100mm.
The demonstration shows how consumers can use TransferJet technology to share multimedia content they have created, in real time, between devices such as cameras, camcorders, smartphones, digital video recorders, TVs, video game consoles and printers. It also has applications in digital signage and public information displays.
Antenova is a member of the TransferJet Consortium, a group of companies who are co-operating to develop the technology. The consortium has been registered as a general incorporated association in Japan since September 2011, and focuses on the development of the specifications, compliance testing processes and certification programme, as well as conducting marketing activities to promote the TransferJet technology, products, applications and services across industries and to consumers.
Antenova has also built a model design for on-board devices (OBD) and vehicle telematics, which it will be showing at CTIA Super Mobility.
The OBD design uses three antennas inside an OBD housing to link to a satellite (GNSS), Bluetooth and terrestrial network, while obtaining optimum performance from all three antennas simultaneously. The design also has a small GNSS RF module to fix location, which Antenova will be showing for the first time.
The company has used the latest antennas from it product ranges in the OBD design: the Armata 3G FPC antenna for penta-band frequencies which operates at 824-960MHz and 1710-2170MHz; a GNSS antenna named Bentoni operating at 1559-1609MHz; and the Weii PCB-mounted antenna which provides a Bluetooth connection at 2.4GHz. All were released this year.
The M10578 GPS and GNSS module is a complete receiver that provides accurate location tracking for OBDs. It uses a Mediatek chipset with an additional LNA to give added performance when mounted under dashboards and out of line of sight with the sky.
The company’s product designers recently introduced the concept of design for integration, which considers how the RF antenna will operate when it is embedded with a manufacturer’s product. The antennas are always used within a customer’s design, so they are designed to provide better RF performance from within the device, and to make the integration of the RF elements easier for the designer. In addition to this, it provides its customers with technical support during the design, integration and testing phases.
“We are demonstrating how a design for an OBD can give great performance, even when new antennas are added to an existing design,” said Colin Newman, Antenova’s managing director. “OBD devices are growing fast in popularity, and the design of the RF components is critical to the overall performance of a device. In particular, Antenova’s engineers have invested many years in designing antennas that work effectively in very small spaces, whilst maintaining the efficiency of the antenna.”
Antenova offers a range of antennas for Bluetooth, Zigbee, Wifi, ISM, 802.11, 3G, GSM, GPRS, Edge, UMTS, WCDMA, LTE, Glonass, Beidou and Gallileo.
