2.4 GHZ Indoor Channel Measurements Data Set

Measurement of the S21,consists of 10 sweeps, each sweep contains 601 frequency points with spacing of 0.167MHz to cover a 100MHz band centered at 2.4GHz.

Data Set Information:

Abstract:

The frequency domain measurement of the scattering parameter, S21, of the wireless channel was carried out using the ZVB14 Vector Network Analyzer (VNA) from Rhode and Schwartz. The measurement system consists of the VNA, low loss RF cables, and omnidirectional antennas at the transmitter and receiver ends. The transmitter and receiver heights were fixed at 1.5 m. A program script was written for the VNA to measure 10 consecutive sweeps: each sweep contains 601 frequency sample points with spacing of 0.167 MHz to cover a 100 MHz band centered at 2.4 GHz. The settings provided a high time-domain resolution of 10 nsec (inverse of the bandwidth) and a time span of (0.167 MHz) = 5.99 μsec . The measurements were designed to examine the WiFi bands specifically, channels 1, 6, and 11 in the IEEE 802.11 standard.

The frequency domain channel measurements were conducted at Khalifa University campus in Sharjah, UAE. The measurements were done in 4 different locations:

1- Lab139 (highly cluttered)

2- Corridor_rm155 (medium cluttered) [with wall from one side and windows from the

other side].

3- Main_Lobby (low cluttered)

4- Sports_Hall (open space).

Details of the dataset:

The frequency domain measurement of the scattering parameter, S21, of the wireless channel was carried out using the ZVB14 Vector Network Analyzer (VNA) from Rhode and Schwartz. The measurement system consists of the VNA, low loss RF cables, and omnidirectional antennas at the transmitter and receiver ends. The transmitter and receiver heights were fixed at 1.5 m. A program script was written for the VNA to measure 10 consecutive sweeps: each sweep contains 601 frequency sample points with spacing of 0.167 MHz to cover a 100 MHz band centered at 2.4 GHz. The settings provided a high time-domain resolution of 10 nsec (inverse of the bandwidth) and a time span of (0.167 MHz) = 5.99μsec . The measurements were designed to examine the WiFi bands specifically, channels 1, 6, and 11 in the IEEE 802.11 standard.

The frequency domain channel measurements were conducted at Khalifa University campus in Sharjah, UAE. The measurements were done in 4 different locations:

1- Lab139 (highly cluttered)

2- Corridor_rm155 (medium cluttered) [with wall from one side and windows from the other side].

3- Main_Lobby (low cluttered)

4- Sports_Hall (open space).

The layout of the floor plan is shown in Floor_Plan.pdf where the red circle represents the transmitter and the green circle represent the receiver location.

The square area was divided into uniform grids with a spacing of one wavelength (12.5 cm) that resulted in a total number of 196 points to capture the small-scale variations. The database was measured under a stationary scenario where there were no movements around the Tx/Rx at the time of measurements. This is achieved since the survey is conducted during low-activity time. This gives a total of 1960 samples because each point has 10 measurements.

In the case of Lab139 there is one set of measurements where the furthest point between the Tx/Rx is 7.1m and then the receiver will moved across the uniform grid. This gives a total of 1960 points.

In the case of Corridor_rm155 there are three set of measurements where the furthest point between Tx/Rx is 7.1m and this gives a total of 1960 points.

In the case of Main_Lobby there are three set of measurements where the furthest point between Tx/Rx is 7.1m and this gives a total of 1960 points.

In the case of Sport_Hall there is one set of measurements where the furthest point between the Tx/Rx is 7.1m and this gives a total of 1960 points.

filename format (environment_Tx/Rx(separation)) i.e Corridor_rm155_7.1 : The environment is a narrow corridor with walls from one side and window from the other side and the Tx/Rx maximum separation is 7.1m and as the receiver is moved across the uniform grid it decreases.

Each file will Loc_xxxx and this will resemble the location of the receiver and each location have ten measurements. The flow of

numbers on the uniform grid is shown in Flow_of_Numbering.pdf

2.4 GHZ室内信道测量数据集

S21的测量包括10次扫描，每次扫描包含601个频率点，间隔为0.167MHz，覆盖以2.4GHz为中心的100MHz频带。

数据集信息：

摘要：

使用Rhode和Schwartz的ZVB14矢量网络分析仪（VNA）对无线信道的散射参数S21进行频域测量。测量系统由VNA、低损耗射频电缆以及发射机和接收机端的全向天线组成。发射器和接收器的高度固定在1.5米。为VNA编写了一个程序脚本，以测量10个连续扫描：每个扫描包含601个频率采样点，间隔为0.167 MHz，覆盖以2.4 GHz为中心的100 MHz频带。这些设置提供了10纳秒（带宽的倒数）的高时域分辨率和（0.167MHz）=5.99μ秒的时间跨度。测量旨在检查WiFi频段，特别是IEEE 802.11标准中的信道1、6和11。

频域信道测量在阿联酋沙迦的哈利法大学校园进行。在4个不同位置进行测量：

1-Lab139（高度杂乱）

2-走廊_rm155（中等杂乱）[一侧有墙，另一侧有窗户另一边]。

3-主大厅（低杂波）

4-体育大厅（开放空间）。

1-Lab139（高度杂乱）

2-走廊_rm155（中等杂乱）[一侧有墙，另一侧有窗户]。

3-主大厅（低杂波）

4-体育大厅（开放空间）。

楼层平面布置如floor_plan所示。其中红色圆圈表示发射器，绿色圆圈表示接收器位置。

正方形区域被划分为具有一个波长（12.5cm）间隔的均匀网格，这导致总共196个点来捕获小尺度变化。在静止场景下测量数据库，其中在测量时Tx/Rx周围没有移动。这是因为调查是在低活动时间进行的。由于每个点有10个测量值，因此总共给出了1960个样本。

在Lab139的情况下，存在一组测量，其中Tx/Rx之间的最远点为7.1m，然后接收器将移动穿过均匀网格。总共得1960分。

在Corridor_rm155的情况下，有三组测量值，其中Tx/Rx之间的最远点为7.1m，总共有1960个点。

在Main_Lobby的情况下，有三组测量值，其中Tx/Rx之间的最远点为7.1m，这总共给出了1960个点。

在Sport_Hall的情况下，有一组测量值，其中Tx/Rx之间的最远点为7.1m，这总共给出了1960个点。

文件名格式（environment_Tx/Rx（间隔）），即Corridor_rm155_7.1：环境是一条狭窄的走廊，一侧有墙，另一侧有窗，Tx/Rx最大间隔为7.1m，随着接收器在均匀网格上移动，间隔减小。

每个文件将是Loc_xxxx，这将类似于接收器的位置，每个位置有十个测量值。流动统一网格上的数字如Flow_of_Numbering.pdf所示。
