LTE and 5G Differences: System Complexity

In this post we discuss the complexity that 5G brings and show some examples of this as compared to LTE including: naming in the 5GS architecture, dual connectivity options in 5G, parameters for L1, base station naming, spectrum aspects.

LTE-Advanced Pro and Massive MTC – Part 2: eMTC

eMTC (aka LTE Cat-M, while in fact, CAT-M is just a definition of UE type/category supporting eMTC) is a low power wide area (LPWA) wireless technology developed by the 3GPP to address the growing need for a solution to address the requirements for IoT applications and Machine-Type Communication (MTC) in terms of cost and power consumption reduction without any significant change to the current LTE deployment.

3GPP Release-15, Part 2: LTE and 5G Study Items

With this blogpost, we continue our discussion on the latest Study Items (SI) which are being worked on in 3GPP Rel-15[1,2]. We posted a similar article in April 2017 on our blog 3GPP Release-15: Further LTE Enhancements and 5G Normative Work Kick-off (do check it out if you haven’t already), and this post will add to the Work Items already discussed in the previous one and will present the latest studies on the LTE enhancements and 5G.

LTE-Advanced Pro and Unlicensed Spectrum

LTE operation in unlicensed spectrum is not limited to its aggregation with WiFi (like with LWA, LWIP and RCLWI)¹. Another approach to utilize the unlicensed spectrum combined with the MNO-controlled LTE networks is based on a specialized version of LTE system designed to cope with the unlicensed spectrum’s requirements. This is referred to as Licensed […]
