Visualising your tickets using Kibana

There are multiple platforms that help you with handling tickets. If you are starting your business, you might simply reply to those emails directly via your mail client, but it quickly becomes too hard to follow and handle all the issues. We chose the tool, from the same vendor, we were already using for different purpose for easy integration. It was great for following threads, tagging and grouping issues, taking notes and automating responses. In this tool we had access to basic statistics like ticket count or time graph with incoming tickets, but we were interested in more advanced stats, which could give us more insight into what is going on. That’s why we decided to integrate that tool with already used by us Elastic Stack.

Why Wi-Fi 6 (IEEE802.11ax) will be different than previous Wi-Fis?

The AP schedules the transmission according to the actual needs, and nobody wastes time on waiting and on collision. So, we end-up having the system that: is more robust towards low latency services; is more spectrally efficient; allows for actually use some QoS profiles; and coordinates the use of spectrum.

5G health issues explained: What’s wrong with the “studies”?

The photon energy of electromagnetic radiation in the microwave spectrum, is by at least 5 orders of magnitude too low to cause any harm in living cells. The only possible impact is a heating effect, but the energy applied by a mobile phone is at least 4 orders of magnitude lower than that used by microwave ovens and can heat human tissues by less than half a degree. The situation around studies of health risks connected to mobile phone usage is discussed. Serious studies show that mobile network and mobile phone usage have no adverse effects on health.

Monitoring and Management in IoT system

IoT System consists of multiple devices and we expect each of them to work flawlessly. There are many reasons why the service might not work in such complex environment. Starting from physical damage of the device, power outage, up to network failure or software bug. Whatever the issue is, we want to be aware of it as soon as possible.

What is SD-WAN (SDWAN)

Specifically, the paradigm called data, control and management plane dissagregation and network automation. Here, you can read about paradigms and characteristics that the SDN idea brings. Dissagregation approach simplifies the process of building & maintaining something called network overlay. Overlay is an abstraction that SDWAN idea relies on (you will read more on dissagregation and overlay concepts below).

Is this anything to worry about? 5G health issues explained

Each time a tower for a cellular network is built or planned to be built in a city or near a rural settlement, there is a new discussion about health issues of mobile phone or network radiation. It is about time to put things back into perspective. I’d like to deal with the reality of mobile network radiation in this post.
