3GPP Release-17: Enhancing 5G

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.

5G Reality Check – 2nd Annual World 5G Summit

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.

Custom monitoring for dense Wi-Fi using Kibana

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.

Spectrum sharing, resource virtualization, machine learning… – CROWNCOM 2019 conference summary

This year’s CROWNCOM conference was held on 11-12 June, in our hometown – Poznan, Poland – discussing the following topics: ML for spectrum management, spectrum sensing, REM, spectrum sharing and management, spectrum assessment and valuation, HetNet and hybrid networking, current 5G standardization and future topics for 3GPP, RAN slicing, business models innovation, which are summarized in this post.

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.

LTE in Unlicensed Spectrum

The “history” of 3GPP system “entering” the unlicensed spectrum regime seems to happened already a long time ago. Tight LTE interworking with WiFi is one way for the MNOs to offload traffic. The other one, discussed within this blogpost, is based on a specialized design of LTE system to be able to cope with ISM/license exempt bands’ special requirements e.g., fair coexistence with other users of this spectrum (e.g. Legacy WiFi).

5 Most Popular Posts From 2018

2018 was a very interesting year for us and technology. We introduced our IoT product “Souly”. 5G entered the normative work in standardization and released the first “version” of 5G. Wi-Fi introduced new security schemes and changed nomenclature. The networking world shifted towards SDN/SD-WAN solutions.

3GPP Release-16: Further LTE and 5G NR Enhancements

This year we have seen the rapid standardization of 3GPP Rel-15, 5G-NR, laying the foundation for the first 5G networks. This blogpost, discusses the ideas and enhancements that are currently being worked on for 3GPP Release-16. These enhancements cover not only 5G-NR, but also LTE which is being advanced in parallel.
