ARELIS unveils hybrid telecoms/TV transmission station at MWC 2015

Published on in Latest News

ARELIS Group, together with its subsidiary, Thomson Broadcast, a global leader in transmission systems, will be present at Mobile World Congress (MWC) 2015, in Barcelona (Spain). At the trade show, the company will unveil its new, green, hybrid telecoms/TV transmission station within the ZENITTHYS project, as well as a completely autonomous base station it has developed.

ARELIS will welcome industry visitors and journalists at Mobile World Congress (MWC) from 2 to 5 March of this year, in Barcelona (Spain). ARELIS will have a stand on the French Pavilion, in Hall 5 (Booth B 61 and Booth B 41).

ARELIS will present its Zero Energy Network In Telecom and Television Hybrid System (ZENITTHYS) project, which features a hybrid transmission solution intended to reduce the environmental impact of telecoms networks’ massive deployments, and the company’s latest solar pilot, which features complete autonomy.

As part of the new ZENITTHYS project — a green, hybrid telecoms/TV transmission station — ARELIS and Thomson Broadcast, its subsidiary, have a long-standing commitment to telecoms and broadcast convergence, as a way to offer hybrid solutions.

This convergence has accelerated with the gradual sale of frequencies in the 800MHz band and, soon, in the 700MHz band. The telecoms industry continues to play a key role in Europe, in spite of falling revenues, increased regulation, and a difficult economic climate. Telecoms operators are expected to invest close to €30 billion annually in next-generation mobile networks between now and 2020.

However, the rise in investment has been hampered by various factors. On the one hand, incomes have tended to drop, while the explosion in data traffic over telecoms networks would require massive investment, and, on the other hand, to guarantee good signal quality and wide coverage, macro base-station antennas are being installed in the centre of cities.

With ZENITTHYS, ARELIS makes it possible to minimize the environmental and societal impact of these two trends. The impact that the proximity of telecoms antennas has on residents may be reduced by splitting the transmission function away from the reception function. Indeed, with ZENITTHYS, the telecoms-reception side is separated from the transmission function and remains close to the houses, but with minimized visual and electromagnetic impact for the inhabitants, while the transmission side, for its part, is achieved via remote sites.

One of the aims of ZENITTHYS is to demonstrate, in specific situations, the capacity to reduce electromagnetic exposure to 0.6V/m with the same Quality of Service. The environmental impact is also reduced by using a mix of renewable energies to power the hybrid telecoms/broadcast station.

ARELIS’ strategy for 2015 and beyond is focused on medium-power energy systems specifically adapted to telecoms deployment, based on the company’s in-house expertise in energy conversion, high-efficiency amplifiers, and energy-management systems. Along with renewable energies, ARELIS is focusing on energy storage and power cells in order to offer a range of off-grid systems and solutions.

At WMC 2015, ARELIS will present its new solar autonomous-system pilot, which is a solar off-grid solution. This renewable-energy functional pilot is the first medium-power off-grid solution integrating transmission capacity. For each piece of equipment integrated into the station, heat dissipation and power consumption have been optimised, and the carbon footprint has been minimised accordingly. To ensure system reliability, the built-in Battery Management System (BMS) can be remotely monitored: it not only controls charge and discharge, but also many energy sources, thanks to an automatic-management functionality.

From an off-grid-system point of view, logistics for the replenishment are then strongly reduced. In turn, this provides operators with a drop-and-forget solution instead of costly replenishment operations in inaccessible or dangerous sites, where the price of a barrel of oil (including delivery costs) may escalate quickly. With telecoms operators’ energy-related operational expenditure representing up to 30% of global expenditure, ARELIS’ autonomous station is an ideal, environmentally friendly solution, which can meet specific customer requirements.

“We aim at proposing an energy-storage and autonomy solution with kW prices which may compete successfully with polluting, pure genset. Our R&D department is focusing on increasing the energy efficiency of [base] stations, while reducing their operational costs. These systems, adaptable to both networks, will ease the telecoms/broadcast convergence and allow their transmission site sharing. Our system does control the entire system and offers telecoms operators sustainable solutions to power their off-grid stations with renewable-energy sources,” says Pascal Veillat, Chairman of ARELIS Group.

ARELIS and the ZENITTHYS Project Leader will welcome visitors and journalists on the French Pavilion (Hall 5, Booth B 61 and B 41) at World Mobile Congress (MWC), in Barcelona (Spain), between 2 and 5 March of this year.
