RFS talks Mobile TV at 3GSM World Congress 2007

Mobile entertainment, and most particularly mobile television, is shaping up to be a central theme of February’s 3GSM World Congress 2007 conference and exhibition in Barcelona. At this year’s exhibition, wireless technology leader, Radio Frequency Systems (RFS), plans to address the many questions, issues and challenges surrounding this emerging market. A team of RFS mobile TV experts will be on hand at its 3GSM World Congress stand to explain prospective mobile TV deployment strategies, and the growing suite of deployment solutions the company can offer.

“Mobile television has thrown open the doors of the wireless world, particularly in terms of industry sector convergence and infrastructure needs,” said Mike Dallimore, RFS Global Product Manager Broadcast, Towers and Defense Systems. “Currently, three network deployment models are proposed for mobile TV--conventional broadcast, cellular network overlay, or hybrid satellite. Four major bands are also being explored: traditional VHF and UHF broadcast, plus L-band (1452 to 1675MHz) and S-band (1710 to 2200MHz). RFS is actively developing unique solutions across all three models and all four bands, resulting in an ever-expanding suite of products that meet a host of diverse needs.”

The RFS mobile TV solution set includes antenna systems suited for high-power broadcast overlay mobile television models, as well as a new and expanding suite of low-power, low-profile UHF omni antennas and panel-style L-band antennas, all ideal for deployment at cellular base stations. The company is also currently working with OEMs in the development of a new generation of antennas and active repeater systems to support S-band hybrid satellite networks.

RFS is already an established leader in the design and manufacture of antenna systems, RF combining and mask filter, and transmission line technology for mobile TV’s earliest deployments and trials. RFS broadband antenna systems and RF combining technology currently supports VHF-band terrestrial digital multimedia broadcast (T-DMB) networks in Korea and China, and UHF-band digital video broadcast to handhelds (DVB-H) trials in Australia and UK.

To support the escalating interest in the mobile TV ‘cellular overlay’ model, RFS is developing an entirely new suite of antennas. The suite addresses the model’s key criteria: essential low-power to ensure emissions remain within limits and co-sited cellular receivers are not blocked, plus antennas that are visually unobtrusive and ultra-lightweight to meet environmental and structural considerations.

The RFS cellular overlay mobile TV suite comprises a selection of compact and lightweight UHF monopole antennas with vertical polarization, including the ultra-lightweight HU6 series of omnidirectional antennas. Weighing just 3.5 kilograms (7.7 pounds), the HU6 is one of the world’s most compact UHF omnidirectional antennas. Complementing the HU6 is the RFS UD-series cardioid broadband dipole array, which supports the entire UHF band in just two models. Later in 2007, RFS will launch a new vertically polarized super-turnstile UHF antenna for mobile TV overlays, which supports the entire UHF band in a single model.

Also in early 2007, RFS will launch a new series of vertically polarized L-band panel antennas, specifically designed to support L-band DVB-H mobile TV overlay strategies. Weighing just 10 kilograms (22 pounds) and measuring only two-meters (6.5 feet) in length, these compact units will provide between 15 to 16.5dBd of gain and power handling of up to 750 Watts. The new antennas will be available in two beam-widths, a 90-degree variant and a 65-degree.
