How can critical communications get the transport sector moving again?

‘The new normal’. It’s a phrase which is being thrown around constantly at the moment, as multiple different business sectors, politicians and commentators try to establish what a post-lockdown UK might look like. How will organisational operations and working practices need to change in order to maintain necessary social distancing measures, whilst getting the economy going again?


The role of traditional radios in healthcare settings during the Coronavirus Pandemic

It is easy to assume that emergency scenarios demand the very latest, next-generation technology. But the reality can be a little more complex.

Reliable communications between medical practitioners in hospitals and healthcare settings are clearly absolutely critical – a matter of life and death. Doctors may need to be summoned within seconds in order to respond to an emergency scenario. The unfolding coronavirus pandemic has brought this into sharper focus than ever before.

Critical ETELM to help develop a pan-European LTE network for public protection and disaster relief

Radio communications specialist part of a consortium working on BroadWay H2020 initiative

30th October, 2019 – ETELM, the radio communications infrastructure specialist, is helping to enable a pan-European interoperable broadband mobile system for Public Protection and Disaster Relief (PPDR).

The company has been named as part of a consortium which has been selected to deliver Phase 1 – the design solution phase – of the BroadWay PCP Innovation programme (H2020).

The BroadWay initiative was created by the public safety agencies from 11 European countries and is operating under the framework of the European Horizon 2020 programme. Collectively, these agencies provide mobile communication services to around 1.4 million responders, and deal with an array of crimes and disasters which are not limited to fixed geographical borders.

On the move: Critical communications for the transport sector

Paul Ward, International Sales Director at ETELM

The pace of change in the transport sector is dramatic. PwC has calculated that global transport infrastructure investment is projected to increase at an average annual rate of about 5% worldwide from 2014 to 2025. And little wonder – a growing global population means more journeys via public and private transport, and more commercial vehicles operating behind the scenes of consumers, working in industries from manufacturing and retail to utilities.


‘Pop-Up Communications’: Applications for temporary LTE networks

Earlier this summer, we announced we had been working with the Fire Department of Indre in France to test a ‘pop-up’ LTE communications network that was capable of being assembled and ready to use in under 20 minutes. This meant firefighters would be able to access reliable broadband services in remote areas where existing network coverage was unavailable.

To form the basis of this network we equipped a command vehicle with an antenna, an LTE eNodeB (manufactured by ETELM), a Halys LTE EPC core and the Streamwide application to reproduce all the critical communication requirements (including emergency calls and broadcasting), geolocation services, and casualty reporting capabilities.

Radio communications specialist ETELM to demonstrate TETRA and LTE interoperability at CCW 2019

Company to showcase live network at stand C86 in Kuala Lumpur

05 June, 2019 – Radio communications specialist ETELM is set to showcase TETRA and LTE interoperability with a live network demonstration at CCW 2019.

The company, which is based in France, will be showcasing its 4G Linked technology, which allows organisations to operate both LTE and TETRA networks as part of their mission critical communications infrastructure.

4G Linked uses the LTE Core as the fully distributed, IP based network, meaning organisations can connect both narrowband TETRA and broadband directly to the same 4G backhaul network.


The functionality gap PMR & LTE 

The functionality gap – should businesses pause for thought before making the change from narrowband PMR to broadband services?

There are many arguments for replacing a legacy PMR technology, such as DMR or TETRA, with mobile broadband services, as technology such as LTE can potentially bring a host of additional benefits and functionality to an organisation. However, there are also concerns about the ability of these services to provide the unfailingly reliable service that is expected of mission critical networks. In this blog we will explore an example of the functionality gap between traditional PMR technology, in this case, TETRA, and LTE and think about the implications for a company looking to implement this new technology.

The Third Generation Partnership Project (3GPP) has said in a statement that release 15 of the LTE standard includes most TETRA functionality, but how this looks in practice remains to be seen.

TETRA and LTE interconnectivity: helping public safety organisations meet the challenges

Paul Ward, our International Sales Director, recently spoke at BAPCO 2019. His theme? How public safety organisations can best meet the challenges of TETRA and LTE interconnectivity.

TETRA, a European standard for a trunked radio system, and LTE, a standard for wireless cellular communication for mobile devices, both have highly useful applications in mission-critical spaces. However, there are some key differences in their functionality, and Paul began by exploring these

Critical Communications and the outsourced responsability myth

Why outsource elements of your enterprise technology?

Some of the drivers that organisations rightly cite include the need to draw on expertise and experience that is unavailable in-house, streamlining management, reducing costs and freeing up internal resource to focus on innovation.
