For cable TV, the "last mile" to the connection at the home is the bottleneck that prevents higher data rates. The last mile is made up of optical fiber and coaxial cables, amplifiers and electrical/optical converters. This mix of optical fiber and coaxial cables is known as a hybrid fiber coax (HFC) network. One option for cable network providers to maximize both the downstream (DS) and upstream (US) data throughput using the existing cable TV network, but without making expensive changes to the HFC network infrastructure, is to employ the data over cable service interface specification (DOCSIS) 3.1. This Application Note discusses the fundamental technological advances of DOCSIS 3.1 and presents measurement solutions from Rohde & Schwarz.

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 of the most important measurements to verify the actual receiver performance of individual devices, and a key metric to compare different devices, in particular.This paper shall give an introduction to receiver performance measurements and discusses the measurement metrics as well as the challenges of over the air (OTA) measurements.

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.
