TSP 5G NR Transmitter

Support signal emulation of the existing multisystem network and the Internet of Things

A single TSP pilot transmitter meets the needs of CW and modulation signal output of all standard protocols and the protocol of the prevailing Internet of Things, saving the fund investment of customers and bringing conveniences for the user to test various signals.

Signal source for 5G frequency check

TSP transmitter support generate CW signal in 700MHz – 6000MHz. With the accurate power output and 0.5dB output adjust step, it is suitable 5G frequency check.

Large power adjustment range

The dynamic adjustment range of a single instrument is 43dB, meeting test needs of indoor and outdoor scenes.

APP remote control and simple deployment

The transmitter is a kind of engineering test instrument, which should be easy to deploy and operate for tests in various scenes. TSP transmitter is controlled by APP within 10m, facilitating remote operation and avoiding radiation injury caused by radio waves in high-power transmission of signals.

Propagation model tuning

Background: The propagation model is used for describing and reflecting the characteristics of the actual wireless signal propagation environment and rules of signal changes to certain degree via one mathematical mode. It represents the propagation environment of specific scene, and characterizes the radio wave propagation loss of specific environments or propagation paths. It mainly focuses on slow fading caused by shadow effects of barriers on propagation paths. The geographic types and topographies of various countries and regions vary greatly. Some parameters of one model to be applied in various regions must be modified, which is known as propagation model tuning.

Solution: As an simulating signal source, TSP pilot transmitter is able to output CW signals. The signal parametersincluding geographic information are collected by the receiver by means of field testing, and the output data are imported into the planned software to adjust model parameters.

Micro base station planing of indoor distribution system

Background: With building of 4G networks and popularization of intelligent terminals, data services are developed rapidly, and user behaviors of indoor scenes are more intensified. Operators can build indoor distribution systems to win indoor data traffic, improve the operation profits, expand new businesses and maintain the user loyalty. In order to improve the quality and management capability of the indoor distribution system, simplify the building of indoor distribution system, the new indoor distribution system was greatly promoted in 2017 in China, and more micro base stations were built. By means of emulation testing of new indoor distribution system, the layout problems of micro base stations can be solved effectively.
Signal coverage testing is able to accurately quantifying and locating base station to simulate the actual deployment.
CW signal and pilot signal are the most common signals for emulation and performance testing. In most of the indoor scenario, signal can be blocked by obstacles or affected by complex area then cause propagation loss. CW signal testing result often varies compare to actual performance in terms of narrow and non-identical indoor environment that leads to RSSI difference. In contrast, pilot signal behaves identical with the actual signal and can be further evaluate by CINR ratio. Thus pilot signal is the primary requirement for micro base station distribution planning.

Solution: As an simulating signal source, TSP pilot transmitter is able to output modulation signals of operating systems of LTE and other existing networks. The cell signal parameters(Channel, PCI, RSRP, RSRQ, SINR, etc.) are collected by the receiver by means of walk test, and the actual coverage of the base station is simulated to simulate the coverage of base station signals, further confirm the locations and quantity of base stations and provide accurate data for the layout of indoor distribution system.

Static scene loss test

Background: The scenes of indoor distribution system vary. Before the distribution system is designed, the signal attenuation in actual scenes should be understood, such as conference rooms, offices, restaurant, hotels, classrooms, etc. The signal attenuation emulation tests of various scenes can provide calculation reference for the indoor distribution system design and improve the final coverage of the distribution system.

Solution: As an simulating signal source, TSP pilot transmitter is able to output modulation signals of operating systems of LTE and other existing networks. The loss properties of actual signals in special scenes (such as doors, walls, fixed barriers, etc.) can be simulated by means of testing with the receiver at the given point, to provide data for the indoor distribution system design.

Acceptance of traditional indoor distribution system

Background: The cable, passive device and ceiling antenna are used as signal transmission parts of the traditional indoor distribution system. The coverage should be verified in acceptance. At the same time, the conformity of the downlink power attenuation, uplink power attenuation and antenna downlink power to design values should be verified.

Solution: As an simulating signal source, TSP pilot transmitter is able to output modulation signals of operating systems of LTE and other existing networks. Cell signal parameters(such as the Channel, PCI, RSRP, RSRQ, SINR, etc.) are collected by the receiver by means of walk test, and the acceptance of indoor distribution system is carried out based on analysis results of wireless signal coverage. The downlink power attenuation, uplink power attenuation and antenna downlink power are subject to sampling inspection with the handheld power test instrument, to verify the conformity to design values. The compliance of the indoor distribution system with engineering acceptance standards is evaluated based on the wireless test and power test data. Faults of the distribution system are located, in combination with the handheld antenna/feeder test instrument.

Multi-operator interference evaluation

Background: At present, networks are run by various operators. As the stations of operators are concentrated and frequency resources are adjacent to each other, mutual influence indoors and outdoors are unavoidable. Operators can evaluate the influence of other networks by simulating the coverage of competition networks and downloading the service rate, SINR value and other parameters.

Solution: As an simulating signal source, TSP pilot transmitter is able to output modulation signals of operating systems of LTE and other existing networks. RF signal parameters (such as the Channel, PCI, RSRP, RSRQ, SINR, etc.) of each operator are collected by the terminal. Change the channel, power and system of the transmitter, and observe the SINR value of the tested cell on the terminal. Evaluate the influence of competition networks by service testing.
