5G and the LTE Evolution

Article & Infographic With the industry’s focus on 5G technology deployment, the next generation of wireless communication as we know it is seemingly right around the corner. As with any new technology turn, there will be a number of challenges and opportunities that arise alongside its commercial launch. Regardless, it’s exciting to witness the evolution… Read more »

UE categories from Release 5 to Release 15

Do you get lost in the world of UE categories? 3GPP specified the first UE categories in Release 5. They define the various key parameters a UE supports in order to achieve a certain data rate. UE category specifications have since evolved and are particularly important for LTE-Advanced Pro. 5G introduces a new way to… Read more »

LTE UE receiver performance measurements

LTE user equipment (UE) receiver performance has significant impact to cellular radio network coverage and capacity. It determines the maximum data throughput across the air interface between the LTE base station (eNB, evolved node B) and the mobile network subscriber UE, thus it determines the total capacity across the air interface. Therefore, it is one… Read more »

LTE Release 9 Technology Introduction – White Paper

The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of operators implementing the technology is strongly increasing around the globe. LTE has become the fastest developing mobile system technology. The same way GSM and WCDMA have been enhanced with additional features over time, LTE… Read more »

WLAN Traffic Offload in LTE

This whitepaper provides an overview of the WLAN offload in LTE as standardized by 3GPP, as well as the enhancements for Wi-Fi standardized by IEEE and the Wi-Fi Alliance. It also describes access methods in the joint network, treats the security, and describes IP mobility. In addition network discovery and selection are explained.

UMTS Long Term Evolution (LTE) Technology Introduction

Even with the introduction of HSDPA and HSUPA, evolution of UMTS has not reached its end. To ensure the competitiveness of UMTS for the next 10 years and beyond, UMTS Long Term Evolution (LTE) is being specified in 3GPP release 8. LTE, which is also known as Evolved UTRA and Evolved UTRAN, provides new physical… Read more »

LTE Transmission Modes and Beamforming

Multiple input multiple output (MIMO) technology is an integral part of 3GPP E-UTRA long term evolution (LTE). As part of MIMO, beamforming is also used in LTE. This white paper discusses the basics of beamforming and explains the eight MIMO transmission modes in LTE Release 9.
