Following on from a previous article on DSL and its scientific bases, I now want to review the fundamentals of another technology: radio. As with a DSL, the ability to transmit data in any radio communications system – from the very first Marconi experiments to 5G networks – is bound by Shannon’s equation, based on the channel’s bandwidth and signal-to-noise ratio. In radio, we also have another interesting equation that can tell us the received signal strength when the transmitter power and frequency, antenna characteristics and distance to the receiver are known.
SD-WAN technology provides customers the capability to manage their own network without requiring managed services from the traditional service providers. However, so that the client can manage its own platform, a powerful tool has to be used, which manages and solves incidents.
For years, the data provision services offered by carriers had a common element: WAN routers or CPEs (Customer Premises Equipment). This hardware device allows the local network of an office to be connected to the corporate service network (thus granting access to everyday applications and the Internet).
In a mature market like telecommunications solutions, where you have many different types and sizes of businesses competing against each other and well-known brands, differentiation and added value are key to helping a company stand out. Therefore, a design strategy that comes up with alternative, robust solutions and the possibility of offering an outward-oriented service – which meets market needs and requirements (Clients and Partners) and, of course, complies with the applicable legal requirements and certifications for these types of technologies – becomes key to competing in global markets.
Every day we hear more news on 5G, its progress and evolution, as the demand for connectivity between vehicles, towns and cities, devices and sensors continues to grow. As you might expect, the railway sector and it’s train communications are no less affected, being one of the main players anxiously awaiting these new developments to adapt the 5G technology and use in their area of railway intra and intercommunication.
