Power electronics in telecommunication equipment

equipo telecomunicacionesThe application of power electronics to communications devices has to do with the processing of the electrical input power using semiconductor devices and reactive elements.

Thus, the raw input power is processed according to a control input that conditions the output power. This conditioning can be carried out by DC/DC converters – that convert the DC input voltage into another DC voltage with different magnitude and possibly isolated or even inverted polarity or through AC/DC converters that produce DC voltage from an AC input voltage.

Dynamic DNS Update

dnsupdater1Nowadays, if you check the public IP address with which you access the Internet, you will find that it often changes.

This is due to the chronic shortage of IPv4 addresses, which are insufficient to cover current service demands. ISPs, therefore, often assign dynamic public IP addresses and mechanisms, such as Carrier Grade NAT (CGNAT), to allow various client devices to connect through a single IP address. Whilst IPv6 emerged to resolve this difficulty, migration to this protocol has proved a real challenge and not advanced as quickly as expected.

First SHA-1 collision

Secured data transfer

In February this year, a team of researchers both from Google and CWI Institute in Amsterdam announced that they were able to generate two PDFs documents with different content that would hash into the same SHA-1 digest. This may lead to a big problem in security that I will try to explain to you but first let’s put ourselves in context.

EMC electromagnetic compatibility and signal integrity

EMC

The growing number of electronic devices and wireless technologies providing ever-increasing performances and speeds requires a set of common standards to ensure EMC electromagnetic compatibility.

Ever since Michael Faraday’s discovery in 1831 of the phenomenon of magnetic induction, which James Maxwell later integrated in his well-known set of equations, we know that any change in an electric current produces a magnetic effect in its vicinity.

Not all Transformations are Digital

digital transformationRecently, regardless of where you look, you’ll find features on Digital Transformation. Digital or physical blogs (including this one) and magazines are full of articles on the digitization of companies, the advantages, drawbacks and risks and the most efficient way to undertake this procedure. And this occasionally leads us to lose sight of the main issue: Digital Transformation involves a number of key technological tools that only make sense if the organization has a profitable business model with defined procedures and is geared to today’s needs.
