3 Operational Modes

Link Analyzer

Analyzing frames for MAC/PHY analysis

RWC5020B provides a function of Link Analyzer for EDT and GWT. Link Analyzer in EDT (or GWT) helps to create a link between RWC5020B and an End Device (or Gateway/Server) Under Test and to analyze the protocol messages.

Transmission of MAC commands :

send MAC commands to your device and check how it works and responds

• multiple MAC commands in a single frame
• all MAC commands defined in LoRaWAN™ with user-configurable parameters
• field selection: frame payload or frame options
• message type selection: confirmed or unconfirmed
• user defined message: editable payload data and port field

Power vs. Time

Continuously monitoring TX power of DUT with respect to data rates(SF)

RWC5020B provides a function of Power vs. Time measurement for EDT and GWT. Power vs. Time measurement in EDT (or GWT) helps to create a link between RWC5020B and an End Device (or Gateway/Server) Under Test and to measure the received power with respect to data rates.

Power vs. Channel

Continuously monitoring TX power of DUT with respect to channels

RWC5020B provides a function of Power vs. Channel measurement for EDT and GWT. Power vs. Channel measurement in EDT (or GWT) helps to create a link between RWC5020B and an End Device (or Gateway/Server) Under Test and to measure the received power with respect to RF channels.

Receiver Sensitivity

Finding the minimum power level which DUT can receive frames from the Tester

Receiver Sensitivity is a function of testing the receiver performance of DUT. RWC5020B sweeps its power level from the start value to the stop value with the step value and checks whether DUT functions properly, and stops immediately after DUT does not function properly.

Signal Generator

Transmitting LoRa / FSK test frames

Signal Generator is a function of transmitting the defined test waveform to DUT repeatedly. Two different modes are provided; LoRa and CW. Especially in case of LoRa mode, various parameters are configurable to compose a LoRa test frame.

Signal Analyzer

Receiving LoRa / FSK frames or continuous waveform (CW) signal and measuring the power

Signal Analyzer is a function of analyzing LoRa / FSK frames received from DUT repeatedly. Various parameters are configurable to receive a specific LoRa® or FSK frame. Additionally TX power of DUT is measured in LoRa, FSK, or CW mode. Frequency measurement is also provided in CW mode.

Key Features

Description

RWC5021P Tester for LoRa / LoRaWAN is a compact dongle-type tester for LoRaWAN protocol analysis for end devices, providing the pre-certification test function and link analyzer function that can be performed in signaling mode. The RWC5020x PC application software provides the LoRaWAN pre-certification test function to verify compatibility with the LoRaWAN protocol, which is fully available for all regions.

Key Features

Pre-certification Test Function

The RWC5020x PC application software provides the LoRaWAN pre-certification test function to verify compatibility with the LoRaWAN protocol, which is fully available for all regions. For LoRaWAN V1.0.2, there are 5 regional options: EU863-870, US 902-928, AS923, KR920-923, and IN865-867. For LoRaWAN V1.0.4, more regions are supported as follows: EU863-870, US 902-928, AS923-1, AS923-2, AS923-3, AS923-4, KR920-923, IN865-867, AU915-928, RU864-870, and EU433.

Link Analyzer

The Link Analyzer enables it to monitor all operations of DUT and dump all the link messages from RWC5020x while communicating with the DUT. The payload editor function helps users evaluate how their DUTs respond to the MAC command(s) or user-defined packets with user-configurable parameters. Moreover, users can also create their own test scenarios with any sequences or combinations of multiple MAC commands and run them consecutively using the script editor.

Description

RWC2020A Interference Generator is an interference generator being able to be used for the purpose of various tests or measurements, e.g. the Listen Before Talk(LBT) test, the Gateway Non-regression tests, the Intermodulation Immunity test and so on. It can generate up to eight multi-tone signals with different output levels per each tone for the LBT test and two tones of up to 20MHz distant for the Intermodulation Immunity test. It also can generate a single tone with phase noise of high performance for the Gateway Non-regression tests.

LBT Test

Listen Before Talk (LBT) is a technique that device enters RX mode and senses the interference signal level before it starts a transmission. It is used to prevent interference or collision between devices that use common frequency bands.

RWC2020A provides a perfect solution to verify LBT functionality of DUT, gateways or end-devices, as a supplementary equipment synchronized with RWC5020A.

It generates up to eight interference signals to occupy frequency bands. The interference signal level, the number of channels, and channel frequencies are editable through RWC5020B LoRaWAN tester GUI or PC software.

CW Interferer Immunity Test

The CW Interferer Immunity Test and Intermodulation Immunity Test which are ones of the Gateway Non-regression tests require CW interference signals with high performance phase noise.

RWC2020A generates a single-tone or dual-tone interference signal for those tests.
