When dealing with networks, both wired and wireless, we can’t fail to mention the security issue. In the case of wireless networks, many users are unaware of the hazards lurking when switching between networks and using unprotected, unverified wireless networks. This article will answer your questions on securing the Wi-Fi network and making it resistant […]

In today’s post, we’ll cover the planning, design, and building of professional, Enterprise-grade wireless networks, i.e. advanced wireless networks. We’ll touch on the selection of equipment and components used in these professional networks. We’ll also review Wi-Fi access network protections in tandem with a component called Cisco ISE, which plays a role of a hub for […]

I want to thank all readers for their interest in the post and the discussions we had during the past months about 5G health issues. There was a high number of supporting comments and requests for clarification, but also quite a few critical comments to both of my published posts (What’s wrong with the “studies” and 5G health […]

What is Wi-Fi 6 (IEEE802.11ax)? How does it compare to Wi-Fi 5 (IEEE802.11ac)? Will older phones connect to Wi-Fi 6? The post combines the most frequently asked questions about Wi-Fi 6.

You may wonder why I’m writing about Dual Connectivity. After all, it comes from LTE in Rel-12, when we are currently within the Rel-16/17 timeframe. The reason for this is that the DC from LTE is treated as a baseline. The enhanced version is incorporated within 5G as one of the main features to allow the so-called Multi-RAT DC (MR-DC). If we look from a broader perspective, we have a multitude of use cases for DC, including LTE-DC, NR-DC, LTE-NR-DC, NR-LTE-DC, LWA. Therefore, this post aims at shedding light on the different aspects of DC, being the legacy feature, which can be extrapolated towards the current situation. 

Recently, we’ve been doing numerous site surveys and verification of Wi-Fi deployments in offices with more than 50APs per office in a managed setup (meaning that the APs are under the supervision of a wireless controller). In this post, I’d like to sketch an overview of the encountered issues and improvement suggestions.

We’ve been bringing the tech trends to the readers of our blog, by continuing to write on certain topics (like 5G, SD-WAN, Wi-Fi networking). As a summary from 2019, we have compiled here a list of the 5 most popular posts from our website.

3GPP Release 17 is about to be started soon. It will mostly be about enhancing and “further” enhancing 5G features in different areas. Regarding the overall timeline, the content of Rel-17 is to be defined in Q4 2019, and the aim is to froze it in Q3 2021.

It was a very interesting event, despite being small in the number of participants. We could listen about the current 5G status from different angles including perspectives from vendors, solution providers, verticals, standardization, governments and research. The one I was missing though, was the MNO “reality check”. I believe that the industry reached now the time, when we are slightly moving beyond the 5G hype and switch from “5G is the answer – now, what was the question” to “who pays for the new infrastructure and spectrum”, being the reality check.

We’ve built a high density and high capacity network. In order to properly operate such network, we designed a custom monitoring and analytics solution based on Elastic Stack and MQTTbeat receiving the measurements from all 494 IoT gateways (i.e. 494 Wi-Fi APs) through an MQTT broker. In this post I’m sheding some light on the different aspects of the solution and custom dashboards.
