This white paper summarizes significant additional technology components based on LTE, which are included in 3GPP Release 12 specifications. The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of commercial networks is strongly increasing around the globe. LTE has become the fastest developing mobile system technology ever. As other cellular technologies LTE is continuously worked on in terms of improvements. 3GPP groups added technology components according to so called releases. Initial enhancements were included in 3GPP Release 9, followed by more significant improvements in 3GPP Release 10, also known as LTE-Advanced. Beyond Release 10 a number of different market terms have been used. However 3GPP reaffirmed that the naming for the technology family and its evolution continues to be covered by the term LTE-Advanced. Therefore LTE-Advanced remains the correct description for specifications defined from Release 10 onwards, including 3GPP Release 12.

|1MA245: Vulnerabilities of LTE and LTEAdvanced Communication White Paper1MA245: Vulnerabilities of LTE and LTEAdvanced Communication White Paper||16.09.2014|
Long Term Evolution (LTE) technology has become the technology of choice for keeping up with the requirement of higher throughput in mobile communication in bands below 6 GHz. It is expected that within the next decade LTE will become the primary commercial standard. LTE is often used to broadcast emergency information in times of natural disasters and national crises and is under investigation for further end use application in government as well as military application fields.
Communication via LTE has some vulnerabilities. This drawback is a matter of concern since it is possible to completely take down the LTE network or at least partially block communication, intentionally with the help of jamming signals, or unintentionally through various forms of interference.
An example of unintentional interference issues is the frequently discussed co-existence issues with Air Traffic Control (ATC) S-band radar and Digital TV bands. The in-device co-existence challenge is also a potentially important issue with the rapid evolution of multi-standard radios.
This White Paper will focus on the vulnerabilities of LTE communication by explaining LTE jamming and unintentional interference problems, address the coexistence issues with other services, and discuss the mitigation options to build a broad perspective on the possible deployment of the LTE technology for future military and civil governmental applications.
Understanding the susceptance of new technologies to known and expected environments is critical to the adoption for defense applications

|7BM76: Correlated Receiver Diversity Simulations with R&S®SFU7BM76: Correlated Receiver Diversity Simulations with R&S®SFU||19.10.2012|
Receiver diversity improves reception quality by using multiple antennas with a preferably low correlation factor between each other. This results in a more robust handling of multipath signals, since a deep fade will then not affect all received signals at the same time. However, the compact dimensions of handheld devices can introduce unwanted correlation due to their dense antenna spacing. In this case, the popular diversity test setup consisting of several independent transmitters will no longer serve the needs of a realistic simulation, since correlation effects have to be taken into account here. A clever solution is to operate the R&S®SFU in split-fading mode in combination with a second transmitter. This can be another R&S®SFU, the R&S®SFE, the R&S®SFE100 or the R&S®SMU200A. In this way, two diversity signals of adjustable correlation for any common broadcast standard are coded in realtime, while their individual multipath profile is precisely specified by the extensive features of the R&S®SFU fader module.

Are there really power peaks that are 20 dB above the average value? Yes, there are. Ever since the introduction of digital transmission technology, it has been necessary to deal with such orders of magnitude. RF power components must be suitably dimensioned to handle the expected voltage peaks and avoid breaking down. If we can determine the crest factor, i.e. the ratio of the peak value to the average or RMS value, with sufficient accuracy (even though it can only be assessed statistically), then we will have solved the question of dimensioning power components. This Application Note is intended to help with this problem by providing some useful insights including basic formulas, some statistical background and a practical look at the limiting factors when it comes to dealing with real transmitter systems.

|1MA135: Path Compensation for MS Fading Tests1MA135: Path Compensation for MS Fading Tests||09.01.2009|
As well as static tests, modern mobile communication standards also stipulate measurements under fading conditions, sometimes with additional white gaussian noise AWGN. Rohde & Schwarz supports these tests with the combination of the R&S®CMU200 Radio Communication Tester and the R&S®SMU200A or R&S®AMU200A Vector / Baseband Signal Generator and Fading Simulator. Applying fading and noise always raises the crest factor of a signal considerably. Thus, automatic path attenuation inside the R&S® baseband fader prevents the new signal peaks from being clipped at I/Q full scale. Any additional attenuation in the baseband, however, makes the RF output fall below its intended level. This application note shows how to achieve an accurate RF output level by compensating for the I/Q attenuation - without modifying the test setup or using additional instruments.

|7BM72: VSWR Measurement in 75 Ω Systems - using the R&S®FSH3-TV TV Analyzer7BM72: VSWR Measurement in 75 Ω Systems - using the R&S®FSH3-TV TV Analyzer||01.03.2008|
The voltage standing wave ratio (VSWR) is one of the parameters in RF systems that measures the impedance mismatch. Under ideal conditions, when the load is perfectly matched to the source, the VSWR will be 1. A mismatch in the system causes reflections that will increase the VSWR and lead to losses in transmission. Although most RF components are typically designed and specified with a characteristic impedance of 50 Ω , applications and system components for cable television are designed and specified with a characteristic impedance of 75 Ω . This application note describes the measurement procedure for VSWR measurements in 75 Ω systems using the R&S®FSH3-TV handheld TV analyzer.

|7BM67: Quality Measurements on Digital and Analog TV Transmitters - Using the R&S ETL7BM67: Quality Measurements on Digital and Analog TV Transmitters - Using the R&S ETL||19.09.2007|
All types of information transmission, including the 'one-way' transmission used in broadcasting, involve feeding a radio frequency (RF) signal to an antenna. This is the essence of the most basic type of transmitter used to emit electromagnetic waves. In the real world, however, a transmitter used for broadcast applications, for example, is much more complex in terms of its functions and design. The different transmitter components must be carefully coordinated. There are many quality parameters that are critical in ensuring that a proper output signal is delivered. Rohde & Schwarz designed the R&S® ETL TV analyzer especially for broadcasting applications. The analyzer allows the measurement of the quality parameters that are relevant in analog and digital broadcasting. This Application Note describes the typical quality measurements performed during compliance testing of TV transmitters.

While RF communication signal distortions in nonlinear transmission paths have been predicted theoretically and studied experimentally for various signals, it is interesting to examine a wideband nonlinear system reaction to a wideband 3G signal and a narrowband 2G signal. Research and testing have demonstrated that, while most vital signal parameters remain within the limits specified by applicable standards even if composite signal power approaches specified maximum power, a relatively high level of spurious emissions caused by cross- and intermodulation can result. To avoid degrading both existing and new systems, this and other signal quality issues must be considered when designing and deploying multitechnology systems.

|1EZ27: Frequency Conversion Measurements with Vector Network Analyzer R&S®ZVR1EZ27: Frequency Conversion Measurements with Vector Network Analyzer R&S®ZVR||25.01.2002|
Vector Network Analyzer ZVR is able to control two external generators via the IEC/IEEE bus in the frequency conversion mode. This feature allows to make automatic measurements on DUTs with up to two frequency converters. For the measurement of the conversion response over the whole frequency range, one of the two generators must be swept. Since this frequency variation is controlled via the IEC/IEEE bus, the sweep time must be increased (automatically) depending on the used generator. Very short sweep time is possible by the use of a generator SME or SMP and the IEC+TTL remote mode. In this case the generator operates in the frequency list mode triggered by ZVR.

|1EE19: Exchanging Data Records between Different Test Receiver Models1EE19: Exchanging Data Records between Different Test Receiver Models||18.01.2002|
Rohde & Schwarz test receivers of the ESXS, ESS and ESXN series are equipped with a 3.5' floppy-disk drive so that receiver settings, scan results, limit lines, transducer factors and whole sets of transducers can be stored on a floppy disk and reloaded into the receiver. Data can only be loaded into the receiver type from which they have been stored. The reason is that data eg from an ESHS30, which operates in the frequency range from 9 kHz to 30 Hz, should not be loaded into an ESVS30 as the data of the two units may be incompatible to because of the different frequency ranges alone (ESVS30: 20 MHz to 1000 MHz). However, in some cases it may be desirable to load an ESVS20 file into an ESVS30, or an ESN file into an ESVN40.

|1EF32: ACP Measurement according to IS 54 (NADC) using the R&S®FSE Spectrum Analyzers1EF32: ACP Measurement according to IS 54 (NADC) using the R&S®FSE Spectrum Analyzers||17.01.2002|
In digital wireless communication systems one or multiple users are assigned to a physical RF channel. With analog systems only one user per carrier is possible. Output spectrum of the transmitter has to be restricted to the assigned channel in order to avoid interference with the neighbor channels. With the switch over to digital modulation formats more user per channel are possible. They share one channel by using only part of the time for transmission (Time Division Multiplex Access, TDMA) or by coding the transmission by orthogonal sequences for distinction to other users (Code Division Multiples Access, CDMA). Beneath the restriction of modulation spectrum with TDMA systems also time behavior of the transmitted signal is critical. One reason is that in a multi-user situation only one user is allowed to transmit within his assigned time slots. Another reason is that by switching a carrier on and off spectrum of the transmitter splatters and causes additional interference in other RF channels.

|7BM05: Fading Channel Simulation in DVB7BM05: Fading Channel Simulation in DVB||06.02.2001|
Fading is known from shortwave transmission, where the received field strength level may strongly vary due to atmospheric disturbances. In analog TV, the term 'fading' is practically unknown. Rather, one talks of 'antenna shadows' or 'ghost images'. The effect in question, however, is fading, ie constant reflection of the eletromagnetic waves emitted by the TV transmitter by walls of buildings, mountain slopes and similar reflecting natural or artificial obstacles. In analog TV, fading is of minor importance since the effects thereof can be eliminated almost completely through the directivity and exact orientation of the Yagi roof antenna for stationary TV reception at home. [[ br />Fading effects can also be observed in analog cable TV, for example in a block of flats linked to the cable network with one or several antenna sockets in every flat. If the taps for the sockets are not match-terminated, reflections with constant level and constant phase arise which may cause level reductions of several dB at exactly calculable points in the cable. [[ br />Moreover, the reception of TV signals broadcast via satellite can be impaired by fading. A known phenomenon is flickering of the received picture, produced by planes flying past or a drop in receive field strength caused by an approaching thunderstorm. All the above receive conditions have one thing in common: reception is stationary with a direct line of sight to the TV transmitter. [[ br />Looking at receive conditions in DVB, the effects in cable and satellite reception (DVB-C and DVB-S) are found to be similar as in analog reception. In these two modes reception is stationary, too. Terrestrial transmission (DVB-T) not only provides for stationary operation but also for portable and mobile reception. This considerably accentuates the effects of fading. [[ br />In this application note we investigate fading effects in DVB, with the emphasis on those in DVB-T signals.

Measurement deviations due to systematic errors of a network analysis system can be drastically reduced by an appropriate system error calibration. After system error correction, the residual measurement uncertainties are - besides the stability, linearity, and dynamic range of the network analyzer system - mainly affected by the quality of the calibration standards and the repeatability of the connections. The effective measurement accuracy of the network analysis system can be determined using the results of successive verification measurements utilizing highly precise verification standards.

|1EZ31: Measurements on Frequency-Converting DUTs using Vector Network Analyzer R&S®ZVR1EZ31: Measurements on Frequency-Converting DUTs using Vector Network Analyzer R&S®ZVR||04.08.1998|
ZVR is a vector network analyzer equipped with selective input channels for determining phase relations. Thus a wide dynamic range can be obtained. For measurements on frequency-converting DUTs (output frequency not identical to input frequency), the generator and receiver frequency ranges can be separately set. For measurements on DUTs using a built-in conversion oscillator, as is the case here, the conversion frequency must be exactly known so that the receiver can be accurately tuned to the respective output frequency. The maximum receiving bandwidth is 26.5 kHz. When a wide dynamic range is required, this bandwidth has to be reduced with the consequence that the requirement for the DUT output frequency and the ZVR receive frequency to be in agreement will be greater.

In addition to the traditional step aperture technique, Vector Network Analyzers from the ZVR family offer a frequency aperture technique, which allows a well defined and constant aperture for group delay measurements also for a nonlinear frequency sweep.
|1EZ29: Measurement Uncertainties for Vector Network Analysis1EZ29: Measurement Uncertainties for Vector Network Analysis||28.07.1998|

It is possible, for instance, to add complete measurement functions - eg measurement of ohmic resistance - and to read out, convert or reload sweep results or to add new scale labelling (eg group delay). Another example is the analysis of sweep curves and the display of results in a window next to the curve. As far as softkey labelling and functions are concerned, operation of the sequence control programs is analogous to the softkey control of the UPD/UPL graphics display.

|1EF09: Power and Modulation Measurements on VHF Transmitters Example: Rohde & Schwarz VHF-FM Transmitter SU1151EF09: Power and Modulation Measurements on VHF Transmitters Example: Rohde & Schwarz VHF-FM Transmitter SU115||04.06.1998|
A whole series of measurements has to be carried out for drafting an acceptance test report for a VHF sound broadcasting transmitter in compliance with ARD Specifications 5/3.1 (= TL 5820-3018 of the Deutsche Bundespost). As in most cases parameters like transmitter output power, frequency stability, spurious modulation, etc. have to be measured in the two stereo channels of the transmitter separately and at different modulation frequencies and frequency deviation, manual-controlled measurements are very time-consuming. In addition, a great variety of test equipment eg AF generator, stereodecoder, level meter, etc. is required for the measurements. FMAB with option FMA-B4 (AM/FM Calibrator / AF Generator) is ideally suitable for these measurements on VHF sound broadcasting receivers. The internal AF generator provides the signals required for the left and the right stereo channel. The MPX signal from the VHF transmitter is decoded by the built-in stereodecoder. As a result many of the tests and measurements required for the acceptance of VHF sound broadcasting receivers can be carried out without any additional test equipment being required. To give an example, a test program running under the graphics user interface Microsoft Windows has been developed for carrying out automatic power and modulation measurements via a PC.

When measuring audio components with unknown transients, the experienced engineer watches the settling of the DUT before accepting a measured result to be valid. The settling function in the UPL/UPD simulates this process and automates it by continuously comparing the measured value with a number of measured values stored before. A measured value is only accepted as being valid if it is within the tolerance limits entered by the user. This application note explains the settling process and gives hints for practical use.
|1EF08: Transient Measurements on GSM/PCN Synthesizers1EF08: Transient Measurements on GSM/PCN Synthesizers||03.06.1998|
The GSM mobile phone system is the first civil radio network using purely digital transmission methods. In addition to the modulation mode GMSK (Gaussian Minimum Shift Keying) itself, both a time and a frequency multiplex method are used. This means for instance that the bits to be transmitted are distributed to several socalled bursts (time multiplex). These bursts are then in turn transmitted at different frequencies in the frequency hopping mode. Due to the frequency hopping mode, the timing used in GSM/PCN networks and the low phase error required for correct data transmission, stringent requirements regarding the frequency transient response are placed on the synthesizers used in the base and mobile stations. For a frequency error of <100 Hz the transient response must be within approx. 100 us to keep the residual phase error caused by the synthesizer sufficiently small. The Modulation Analyzer FMA/FMB with its high-precision AM and FM demodulators featuring DC coupling capability is particularly suitable for an uncomplicated measurement of transient responses in conjunction with an oscilloscope. Both the FMA with its low residual FM in the GSM band from 890 to 960 MHz and the FMB, which in addition also covers the PCN band from 1710 to 1880 MHz, provide in conjunction with the fast transient response of the FM demodulator the characteristics required. Highest precision regarding the transient response is provided by the FMA/FMB's special function 'IF 300 kHz'.

DECT standard ETS 300 175-2 prescribes among others measurement of the transmit power and the unwanted power in adjacent channels. Following a brief introduction into DECT, this Application Note describes the standard-conforming measurement of the normal transmit power NTP and the unwanted adjacent-channel power ACP using a spectrum analyzer from the FSE family ( firmware version 1.63 and higher). Option FSE-B7 (Vector Signal Analyzer) is required for measuring the normal transmit power NTP since the signal must be demodulated for this measurement. Due to the wide dynamic range of FSEA20 and FSEA30, the adjacent channel power ACP can be measured without bandpass filters suppressing the transmit channel. Option FSE-B7 is not required for measuring the adjacent-channel power.
