Probe requests of 24 devices in a semianechoic chamber

This dataset was created collecting probe requests generated by 24 devices inside a semianechoic chamber. The scanning duration is around 22 minutes and for each probe request acquired, several details are reported: - MAC ADDRESS: for privacy reasons the id annotated in mac column is the result of hashing with SHA256 algorithm on the original mac address - SEQ: the sequence number of the probe request - TIME: is the unixtime of istant when the probe request where collected - ID_X: for each column, the X value indicates the information element ID and its value represents the length for that field - OUI: indicates the Organizationally Unique Identifier directly from the original mac address - VENDOR: contains the vendor extracted from the original OUI.本数据集通过采集半消声室（semianechoic chamber）内24台设备生成的探测请求（probe request）构建而成。 扫描时长约为22分钟，针对每条采集到的探测请求，将报告多项详细信息： - MAC地址（MAC ADDRESS）：出于隐私保护目的，MAC地址列中所标注的标识符为原始MAC地址经SHA256算法哈希处理后的结果。 - SEQ：该探测请求的序列号 - TIME：采集该探测请求时刻对应的Unix时间戳（unixtime） - ID_X：每一列的X值代表信息元素标识符，其对应的值为该字段的长度 - OUI：直接取自原始MAC地址的组织唯一标识符（Organizationally Unique Identifier） - VENDOR：包含从原始OUI中提取的设备厂商信息。
