Evolutionary & Disruptive Visions Towards Ultra High Capacity Networks

With many groups now beginning to consider the drivers for 5th Generation wireless networks, this timely document includes contributions from 20 IWPC member organizations from around the world and aims to advance certain understandings and concepts for adoption in wireless systems to be deployed beyond the year 2020. This 89 page document covers a broad range of 5G topics with emphasis on mm-wave.

Mobile Data Backhaul: The Need For E-Band

Now that the need for ultra high capacity radios has become an unofficial requirement with a potentially large market backing it, the call for more spectrum savvy radios is in order. Traditional wisdom would have us assume that the legacy pure-play millimeterwave equipment vendors have this market clenched; however, every time there is a technology shift, as is occurring with the E-Band market, it opens the field up to new market leaders and a new competitive landscape. Thus, we have seen traditional microwave vendors throw their hats into the millimeterwave ring with various levels of commitment from OEMing/private labeling traditional millimeterwave vendors’ radios to designing their own millimeterwave radios.

TU Dresden uses National Instruments Platform for 5G Research

Wireless consumer's insatiable demand for bandwidth has spurred unprecedented levels of investment from public and private sectors to explore new ways to increase network capacity. Service providers, now deploying fourth generation networks, are already beginning to look toward and plan for fifth generation networks (5G) to meet the escalating demand. Researchers at TU Dresden (TUD) have begun investigations into 5G technologies using a graphical system design approach and National Instruments' software defined radio platforms. Using the NI platform, TUD researchers significantly compressed the time to transition from concept to prototype.

Solutions for Enabling Fast, Accurate and Efficient Testing of Voice Quality in LTE User Equipment

This application note is designed to provide you with the latest insights on how to best address the long list of test requirements when testing the voice quality of LTE UE, with the right VoIP test building blocks. Successfully providing voice support on LTE will require UE developers to bring together a host of new features and capabilities. Many of these items have been around for a while but have not yet been applied to mobile networking. Others are completely new. Regardless, bringing them together will likely cause significant test pain, as they will need to be tested in conjunction with LTE and/or IMS to be fully exercised.

Small-Signal Intermodulation Distortion in OFDM Transmission Systems

A system that utilizes OFDM/OFDMA, such as the E-UTRA (LTE) downlink or the IEEE 802.11a/g and the IEEE 802.16 physical layers, transmits OFDM symbols, each comprising a number of modulated sub-carriers carrying data or pilot symbols, with inter-subcarrier spacing being equal to or an integer multiple of a fixed frequency. The channel bandwidth (B) is determined by the number of 'occupied' (modulated) subcarriers and the subcarrier spacing.

IMS Architecture: The LTE User Equipment Perspective

The IP Multimedia Subsystem (IMS) dates from 3GPP release 5 almost a decade ago, but is now becoming a reality with the rollout of IMS-based LTE networks. IMS enables convergence on multiple fronts, including access types (fixed, mobile), service types, application control functions and convergence between telephony and traditional data delivery. This paper presents a high-level technical view of the IMS architecture as seen by LTEcapable User Equipment (UE).

Voice and SMS in LTE

This white paper summarizes the technology options for supporting voice and short message service (SMS) in LTE, including circuit switched fallback (CSFB), SMS over SGs, and voice over LTE (VoLTE). It includes background information on the standardization process, and the commercial implications for the different options. The white paper also addresses test and measurement requirements resulting from the support of voice and SMS in LTE.

Minimizing PIM Generation From RF Cables and Connectors

Understanding mechanical tolerances, coaxial design details and connector materials used in cable assemblies helps produce communications equipment with the lowest levels of passive intermodulation (PIM).

Solutions for LTE-Advanced Physical Layer Design and Test

LTE-Advanced (LTE-A) is an emerging mobile communications standard that boasts a number of significant benefits, including the ability to take advantage of advanced topology networks and achieve target peak data rates of 1 Gbps in the downlink and 500 Mbps in the uplink. This white paper covers using signal generation and analysis to overcome challenges associated with carrier aggregation.

Electronically Scanned Arrays for Fast Testing of Large Antennas
