Ramboll provides consultancy service - audits & design - for Indonesia’s largest Independent Tower Company, Tower Bersama Group (TBG), who acquired 2,500 mobile towers from the country’s no. 2 operator PT Indosat.
Telecom operators in Dubai want the new innovative camouflage solution, Palm Tree with date fruit called Arabian Date Palm Tree. Ramboll was requested by client in Dubai to provide so called “Arabian Date Palm Trees”.
Reliance Jio has just awarded Ramboll in India with a major contract for tubular telecom towers. The project is a further consolidation of Ramboll's position as a global leader within analysis, design, and construction of masts and towers.
In the autumn of 2015 Ramboll performed a comprehensive analysis of the mobile coverage in a newly-constructed hospital wing. All operators and mobile technologies supported were measured in the frequencies supported by the DAS. The goal is to achieve 100 % coverage all over the facility. The analysis ensured that the handover, when entering and leaving the building, functioned correctly.
Ramboll has been the main contractor for the supply and erection of a 125m tall tower in Karlskrona, Sweden. The contract included the design and delivery of a special rock foundation.
The new mobile LTE (4G) network is being implemented all across Sweden. This requires an upgrade of many of the existing structures – primarily guyed masts – to carry the increased antenna loads. Ramboll assists 3GIS in their upgrading process, in an one-shop solution.
Ramboll has prepared detailed fatigue analyses of two typical 300 m guyed masts in Sweden. The purpose of the investigation was to establish the lifetime of guyed masts now that they are around 50 years old.
It is a challenging task to implement Digital Terrestial Television to the interface of 40 years old existing masts. This task requires expert engineering skills and an experienced mounting team for a successful chopper placement of the new antennas. Twenty 16 meter long antennas are mounted over a period of 2 years up to July 2008 in order to realise the political decision of changing to digital television in Norway.
In the spring of 2015, Ramboll has completed a comprehensive benchmark of two mobile operators, measuring voice and data transfers on both 2G and 3G networks.
Those living near sites containing telecommunication masts are often concerned about the level of electromagnetic radiation (EMR) emitted by the antennas. These concerns are sometimes the source of strain within neighbourhoods, as well as between local people and mobile operators.
Due to increasing mobile use, many countries are considering new ways to regulate the use of the 700MHz band. Today, this is allocated to radio and television broadcast (DTT - Digital Terrestrial Television).
Increasing demand for mobile telephone coverage and broadband services in Africa call for massive expansion in mobile networks on the African continent. Today Ramboll’s design philosophy is well-known by mobile operators and networks vendors who request supply of towers from Ramboll Telecom for the African market.
On the 15th of May 2016 the old 320 m guyed mast in Borås was exposed to sabotage and 200 m of the top of the mast fell down to the ground. Due to the collapse Teracom wanted a new mast designed, manufactured and installed as soon as possible.
According EU directive 2013/35/EU all companies must know the EMR levels that their workers are exposed. This can be done by theoretical calculations, or by measuring the actual levels.
Many citizens have expressed concern if the EMF levels (electromagnetic fields) in their homes are a health and safety hazard. The citizens have requested a check of the EMF levels.
In some Swedish public schools, the teachers were worried that the recently installed WiFi network could have a harmful impact on the children.
EMR measurement and reporting. General consultancy services.
For a newly established train line in California USA, Ramboll has performed a health and safety evaluation of EMF levels from electric trains.
In response to concerns that levels of EMR fields (Electromagnetic Radiation) from rooftop antennas could potentially pose a health risk to workers on the roof, Ramboll conducted a study for a London based university to determine the overall risk.
Due to rapid development in the Indian telecoms market, there is a great demand to fully utilise existing telecoms infrastructure. This has led to an increase in sharing of tower infrastructure by telecoms companies. The associated proliferation in site tenancies has resulted in the installation of additional electrical and electronic equipment.
Ramboll Thailand and Ramboll Indonesia together developed a SMART site concept for NSN and Ericsson. The idea with the smart site is to minimize overall site costs. The Built-in Equipment Platform (BEPF) which is designed as the universal fixation which can be mounted to bottom section of different Ramboll 3-legged tubular tower families.
Ramboll Telecom Indonesia has entered a frame agreement with Nokia Siemens Networks (NSN) for delivery of towers throughout Indonesia. As part of the agreement it was agreed that Ramboll would educate the contractors in the Ramboll Tower concept as well as supervise the first installation of towers.
RTI are continuously meeting clients across India introducing the Ramboll design. With the presence of Ramboll IMIsoft in Hyderabad RTI were able to meet with WTTIL and in record time all technical discussions and commercial negotiations were completed and the manufacturing and supply of Ramboll towers could start.
Ramboll has performed tower loading validation activities (TLVA) since January 2010 on all Indus telecoms sites.
A new overhead transmission line is needed in order to secure the quality of supply in Denmark. Denmark puts a great effort into reducing CO2 emissions by expanding the production capacity based on renewable energy. Consequently, a more flexible electricity grid is needed to be able to transport the power from the offshore wind parks to the consumers as well as increasing the transmission capacity between international markets.
In order to enhance the view of Little Belt, 12 km of overhead line was removed and replaced with cable. Ramboll was responsible for the project description of the dismantling of the cables and the 120 m tall towers – as well as designing foundations for the new towers.
When antennas from different telecommunication operators were installed in the overhead transmission line towers of Energinet.dk, a static analysis of the towers and the foundation was needed. Ramboll assisted Energinet.dk with all antennas installed in the their towers.
Banedanmark has decided to establish GSM-R coverage along all tracks in Denmark including tracks owned by private operators. Ramboll has as won the Civil Works part of the project, which in total was approx. 350 sites covering all of Denmark. About 200 of the sites were tower sites.
