We conduct to our knowledge a first measurement study of commercial 5G performance on smartphones by closely examining 5G networks of three carriers (two mmWave carriers, one mid-band 5G carrier) in three U.S. cities. We conduct extensive field tests on 5G performance in diverse urban environments. We systematically analyze the handoff mechanisms in 5G and their impact on network performance, and explore the feasibility of using location and possibly other environmental information to predict the network performance.

5Gophers 1.0 is a dataset collected when the world's very first commercial 5G services were made available to consumers. It should serve as a baseline to evaluate the 5G's performance evolution over time. Results using this dataset is presented in our measurement paper - "A First Look at Commercial 5G Performance on Smartphones".

This dataset is being made available to the research community.


All the files are in CSV format with headers that should hopefully be self-explainatory.

This dataset contains thousands of Channel State Information (CSI) samples collected using the 64-antenna KU Leuven Massive MIMO testbed. The measurements focused on four different antenna array topologies; URA LoS, URA NLoS, ULA LoS and, DIS LoS. The users channel is collected using CNC-tables, resulting in a dataset where all samples are provided with a very accurate spatial label. The user position is sweeped across a 9 squared meter area, halting every 5 millimeter, resulting in a dataset size of 252,004 samples for each measured topology.


The dataset contains Channel State Information (CSI) samples, recorded with the KU Leuven Massive MIMO testbed. This was done for many user positions laying on a grid. The Base Station (BS) is equipped with 64 antennas, each receiving a predefined pilot signal from each position. Using these pilot signals, the CSI is estimated for 100 subcarriers, evenly spaced in frequency over a 20 MHz bandwidth. As a result, the complex numbered matrix H represents the measured CSI for one location. This matrix spans N rows and K columns, with N being the number of BS antennas and K the number of subcarriers. For further details about the system, the National Instruments Massive MIMO Application Framework documentation can be consulted.  

To collect the CSI from many different user locations, four single-antenna User Equipments were positioned in an office. Their antennas were moved along a predefined route using CNC XY-tables. This route zigzagged along a grid taking steps of 5 mm. The total grid spans 1.25 m by 1.25 m. By using these XY-tables the error on the positional label is less than 1 mm, which results in a very accurate dataset. This resulted in a dataset containing 252004 CSI samples spatially labelled with an accuracy of less than 1 mm.  
Furthermore, the testbed’s BS is designed to be very flexible in the deployment of the antenna array. This allowed for the creation of three different datasets, each with a unique antenna deployment. First, a Uniform Rectangular Array (URA) of 8 by 8 antennas was deployed, both in LoS and NLoS, using a metal blocker. Second, Uniform Linear Array (ULA) of 64 antennas on one line was deployed. Finally, the antennas were distributed over the room in pairs of eight, making up the distributed (DIS) scenario.  

The different deployments can be seen in the picture in attachment. In all cases, the antennas are placed 1 m from the XY-tables. The yellow rectangles on the figure depict the 1.25 m by 1.25 m areas where the XY-tables are able to move the users in. The spacing in between the XY-tables is dictated by the space needed for the motors powering the movements and the cables connecting them to the controllers. These tables were synchronised over Ethernet with the BS to ensure the sampled H has a correct spatial label, enabling a highly accurate dataset. 

During the measurements, the BS was configured to use a centre frequency of 2.61 GHz, giving a wavelength λ of 114.56 mm. The system used a bandwidth of 20 MHz. The origin of the space was defined as the middle of the URA. From this point in space, the x- and y-positions of the users and antennas were measured. These locations are provided in 3D in the dataset.


This dataset contains the measurement data of a channel sounding campaign in the hull of a bulk carrier vessel at mmWave frequency 60.48 GHz. The directive radio channel for Line-of-Sight (LOS) communication is measured using the Terragraph channel sounder. An antenna beam width dependent PL model is created. At mmWave frequencies, LOS PL in the vessel is close to PL in a free space environment, but angular spread values are lower compared to other indoor scenarios.

The processing results of these measurements are presented in the following two papers.


We performed Line-of-Sight measurements in the hull of a bulk carrier vessel using the Terragraph channel sounder. The measurements are performed in the engine room and steering control room of the Premium Do Brasil, a 200 m long juice carrier. We selected 6 locations and measured at different distances in order to have a measurement every 0.25 m and 2 measurements (at 2 different locations) for every 0.5 m. The measurement data can be found in the ZIP archive DataPort.zip, which also contains some pictures in the **Setup** directory.

The **MeasurementData** directory of the ZIP archive contains a single folder for every measurement, with the following naming structure: X_locY_Z in which:
X: Date of measurement
Y: Location of measurement (see **Setup** folder)
Z: Distance between the two nodes

Every folder contains the log file with the configuration settings, the results and normalized results files and a plot of the beam sweep path loss info. No GPS info is recorded. All the path loss data is combined and fitted to a one slope model.


This dataset was created for the following paper: Seonghoon Jeong, Boosun Jeon, Boheung Chung, and Huy Kang Kim, "Convolutional neural network-based intrusion detection system for AVTP streams in automotive Ethernet-based networks," Vehicular Communications, DOI: 10.1016/j.vehcom.2021.100338.



The following devices are connected to the automotive Ethernet testbed:

  • a RAD-Galaxy: BroadR-Reach switch
  • two neoECU AVB/TSN (AVB/TSN Endpoint Simulation): configured as an AVB talker and an AVB listener, respectively
  • a RAD-Moon: a media converter (between BroadR-Reach and Ethernet)
  • an USB Camera connected to the AVB talker

The dataset contains four benign (attack-free) packet captures. 

  • driving_01_original.pcap (about 10 min)
  • driving_02_original.pcap (about 16 min)
  • indoors_01_original.pcap (about 24 min)
  • indoors_02_original.pcap (about 21 min)


We suppose that an attacker injects arbitrary stream AVTP data units (AVTPDUs) into the IVN. The goal of the attacker is to output a single video frame, at a terminal application connected to the AVB listener, by injecting previously generated AVTPDUs during a certain period. To demonstrate the attack, we extract 36 continuous stream AVTPDUs (single-MPEG-frame.pcap) from one of our AVB datasets; the extracted AVTPDUs constitute one video frame. Then, the attacker performs a replay attack by sending the 36 stream AVTPDUs repeatedly. Check *_injected.pcap files for the result of the replay attack.


To open the packet captures, we recommend researchers use Wireshark and the following plug-ins:

The MIMOSigRef-SD dataset was created with the goal to support the research community in the design and development of novel multiple-input multiple-ouotput (MIMO) transceiver architectures. It was recorded using software radios as transmitters and receivers, and a wireless channel emulator to facilitate a realistic representation of a variety of different channel environments and conditions.


The MIMOSigRef-SD dataset is provided in the form of 8 individual TAR files. Each file represents one of the 8 modulation schemes utilized in our dataset. Within each file, the data is organized in a similar format: Naming of the contained folders represents the modulation scheme and order, channel environment, MIMO configuration, and type of MIMO. An example of such naming is: 16QAM – Vehicular B – (TX2 – RX1) – Spatial Diversity. This provides easy access to the information of interest.


Accurate and efficient anomaly detection is a key enabler for the cognitive management of optical networks, but traditional anomaly detection algorithms are computationally complex and do not scale well with the amount of monitoring data. Therefore, this dataset enables research on new optical spectrum anomaly detection schemes that exploit computer vision and deep unsupervised learning to perform optical network monitoring relying only on constellation diagrams of received signals.


The dataset contains a set of folders, each one representing one normal/anomalous case.

Within each folder, a number of .mat files contain the raw data collected from VPITransmissionMaker. The images folder contains the rendered constellation diagrams.

To render your own constellation diagrams, check the "generate_plots.m" file in the root folder.

Bluetooth communication is widely adopted in IoMT devices due to its various benefits. Nevertheless, because of its simplicity as a personal wireless communication protocol, Bluetooth lacks the security mechanisms which may result in devastating outcomes for patients treated using wireless medical devices.


The prototype transmitter was placed on the floating platform for generating the inductive magnetic field, and the distance between the rotating magnet and the sea surface is 35 cm to 45 cm. The waterproof ferrite-rod coil was hung in the seawater as a receiving antenna at a depth of 10 m.

This repository hosts the data and code for studying the UAV positioning problem under obstructive environment. This study focuses on the scenario of the low-altitude UAV to ground communication in a dense urban environment. There could be a lot of local structure, such as buildings and trees, that blocks the communication signal. As a result, the UAV should be optimized to smartly explore a good propagation condition to communicate with the user. At the same time, the UAV also needs to balance the communication link with the BS.
