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 »

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 »
