The Internet of things (IoT) has emerged as a topic of intense interest among the research and industrial community as it has had a revolutionary impact on human life. The rapid growth of IoT technology has revolutionized human life by inaugurating the concept of smart devices, smart healthcare, smart industry, smart city, smart grid, among others. IoT devices’ security has become a serious concern nowadays, especially for the healthcare domain, where recent attacks exposed damaging IoT security vulnerabilities. Traditional network security solutions are well established.

Using Wi-Fi IEEE 802.11 standard, radio frequency waves are mainly used for communication on various devices such as mobile phones, laptops, and smart televisions. Apart from communication applications, the recent research in wireless technology has turned Wi-Fi into other exploration possibilities such as human activity recognition (HAR). HAR is a field of study that aims to predict motion and movement made by a person or even several people.

As Science and technology evolve, the environment is getting affected daily. These cause major environmental issues like Global Warming, Ozone layer depletion, Natural resource depletion, etc. These are measured and regulated by local bodies. The data given by the local bodies are average values for a large area, those data might be inaccurate for a small sector or isolated zone. However, there are few techniques such as WSN (Wireless Sensor Networks), IoT (Internet of things) which measures and updates real-time data to a cloud server to overcome the trouble.

Industrial Internet of Things (IIoTs) are high-value cyber targets due to the nature of the devices and connectivity protocols they deploy. They are easy to compromise and, as they are connected on a large scale with high-value data content, the compromise of any single device can extend to the whole system and disrupt critical functions. There are various security solutions that detect and mitigate intrusions.

This is a CSI dataset towards 5G NR high-precision positioning,

which is fine-grainedgeneral-purpose and 3GPP R16 standards complied

 

 

The corresponding paper is published here (https://doi.org/10.1109/jsac.2022.3157397).

5G NR is normally considered to as a new paradigm change of integrated sensing and communication (ISAC).

Instructions: 

 

The dataset_[SNR]_[Scenario]_[date_time].mat contains: 

1) a 4-D matrix, features, representing the feature data, and

2) a structure array, labels, labeling the ground truth of UE positions.

[SNR] is the noise level of features, [date] and [time] tell us when the dataset was generated.

The labels is a structure array. labels.position records the three-dimensional coordinates of UE (meters).

The features is a matrix, Ns-by-Nc-by-Ng-by-Nu, where Ns is the number of samples, Nc is the number of MIMO channels, Ng is the number of gNBs and the Nu is the number of UEs.

The value of Ng corresponds to the number of UEs in labels.

 

 Colsed beta test is running.

In the first phase, we plan to provide three researchers (groups) with a full version of dataset generation and 864 core/hours of computing resources. You can use CAD software to make custom map files and save them in '.stl' format. Supported scenarios include, but are not limited to, typical 5G positioning scenarios such as enclosed indoors, city canyons, etc., which should not exceed 1,000 square meters in area.

 

In addition, you can customize the location, number, and other specific parameters of the base stations and UEs in the map, such as carrier frequency, number of antennas, and bandwidth. If you don't know the specific parameters, you can just submit the map file, and we'll generate your custom dataset based on the default parameters.

 

Customized datasets with fine-grained CSI for each point and their detailed documentation will be returned after they are generated.

To get your dataset for 5G NR Positioning, please contact us by email. We will start your dataset-generation after confirming your identity and requirements.

 

 Release note 

2021-07-23 :

1) Recruit participants for colsed beta test.

2021-07-22 :

1)Expend our dataset with more CSI data with low SNR levels noise.

2)We set up an open system for researchers to upload their own scene maps to obtain customized data sets.

Closed beta test will start after suggestion collection.

2021-07-18 :

1)Expend our dataset with more CSI data with different SNR levels noise.

2)Publish map files for Scenario 1 indoor office.

The uploaded data are for the paper: "A Wearable Skin Temperature Monitoring System for Early Detection of Infections". Baseline kin temperature measurement data from all 5 volunteers (subjects) who wore the wearable band for 3-5 days are included along with 5-day temperature measurement data with anomalies of one volunteer who wore both the smart band and a heating pad. Augmented data generated using the methods described in the paper for COVID-19 infection anomaly detection are also included

This dataset includes FTM WiFi measurements made with several ESP32-S2 devices in different indoor and outdoor environments. The measurements include the actual distance between devices as well as the RTT (Round Trip Time) values generated by the module.

Instructions: 

# ESP32 S2 FTM Measurements

=========================

 

FTM measurements were created using several ESP32-S2 devices. They are presented in two different formats: rosbag (http://wiki.ros.org/rosbag) format and matlab format.

 

## ROS BAG records

 

The measurements can be found in the directories:

 

- AC

- Indoor

- Outdoor

 

The ROS messages are of type ESP32S2FTMRangingExtra and ESP32S2FTMRanging. These message types can be found in the following repository: https://github.com/valentinbarral/rosmsgs

 

The following fields are included within each message:

 

- anchorId: Identifier of the module that acted as beaconin the measurement.

- rtt_raw:   RTT   value   averaged   among   the   differentframes sent. In nanoseconds.

- rtt_est:  RTT  estimation  created  by  the  ESP32-S2firmware. In nanoseconds.

- dist_est:  Distance  estimation.  Internally,  the  rttestvalue is used to calculate this value. In meters.

- num_frames: Number of frames successfully sent dur-ing the RTT communication.

- frames: A list of all successfully sent frames.

 

Each individual frame includes the following information:

- rssi: Received signal strength. In dBm.

- rtt: RTT value in that frame. In nanoseconds.

- t1:  Outgoing  timestamp  of  the  first  packet  from  thesender. In picoseconds.

- t2: Timestamp of reception of the ranging request at thereceiver. In picoseconds.

- t3: Timestamp of the response message at the receiver.In picoseconds.

- t4:  Timestamp  of  reception  of  the  response  messagefrom the receiver at the sender. In picoseconds.

 

## Matlab logs

 

The measurements in matlab format are in the .mat file. This file includes four 1x1 struc elements:

 

- indoor

- outdoor20

- outdoor40

- sa

 

Each of these structures has the following fields:

 

- actualDist: Actual distance.

- rttRaw: RTT   value   averaged   among   the   differentframes sent. In nanoseconds.

- estDistRaw: Distance estimate using rttRaw.

- absErrRaw: Absolute distance error of estDistRaw.
