The Technology and Our World Today
In normal LTE networks, the users are sent to legacy CS networks (2G/3G) via CSFB mechanism whenever they have to make a voice call. CSFB is a good solution and it has evolved alot but still it takes longer time. Read More
In this article, I will try to explain the basic planning principles for 5G in comparison to its predecessor (LTE). I remember that during the introduction of LTE, it took quite some time for everyone to understand its planning and Read More
I have received a lot of requests to explain CSFB as it is one of the more complicated LTE KPIs. So, here is a brief explanation on how CSFB works and what are various ways to optimize the KPI itself. Read More
As we are moving towards 5G, the concept of Massive MIMO and beamforming are getting much more attention. Like any other Access Technology, there are two aspects to this – capacity and coverage. The essence of Massive MIMO is the Read More
This article discusses the enhancements in spectral efficiency and scheduling algorithms introduced in the 5G NR specifications. The increase in spectral efficiency due to various features and scheduling algorithms ensures that 5G can have higher throughput compared to its predecessors. Read More
In the first topic, 5G NR: What makes 5G better than LTE, I discussed about the major enhancements that 5G exhibits over the current LTE technology. This article will describe the changes along with their purposes for each of the Read More
Recently, 3GPP has shared the Non-StandAlone 5G New Radio (NR) details in Rel15. Naturally, everyone wants to know what changes and enhancements it holds to achieve the high throughput and low latency targets. So, I thought that I would write Read More
Since I got a lot of requests to explain the LTE paging mechanism and paging capacity, so I decided to write a couple of short articles on these topics. Paging is a mechanism to initiate services for UEs that are Read More
I explained the gains of optimizing the PDCCH (control part) of the LTE subframe in my previous article. Let’s have a look at the data part (PDSCH) and find out various ways to improve it’s efficiency. The spectral efficiency is Read More
One of the most important KPI is the LTE Call Drop Rate. Every network is striving to improve this KPI and it has become more important in LTE since the introduction of VoLTE. In simple words, a call drop in Read More
