VT Data - 2024/25 Drive Test - Speed Test Totals

Program Description The Vermont Mobile Wireless Drive Test Program is an initiative led by the Division of Telecommunications and Connectivity at the Vermont Department of Public Service to evaluate the availability and performance of mobile voice and data service along roadways in Vermont. The program involves a “test-kit” consisting of consumer grade cell phones and specialized software to capture a real-world user experience. The software records mobile service availability, broadband speeds, and voice call completion. The collected data identifies areas where coverage is available, as well as areas where service is unreliable or non-existent. Please note the Drive Test results capture a "snapshot" in time and may not reflect the current conditions Data Description Data Test Totals This polygon feature layer features data summarized in H3 hexagons Resolution 8 from individual data speed tests conducted in 2024 and 2025. The data was collected for four mobile service providers in the State of Vermont: ATT, FirstNet, T-Mobile, and Verizon. This data includes a combined field that includes results from every test in each hexagon where testing was conducted. The test data includes results from each attempted test collected during the program and includes the following attributes: Speed Test Totals Schema Vendor - name of mobile service provider tested; includes ATT, FirstNet, T-Mobile, Verizon, and Combined values Pass– a count of total passed tests inside the hex Fail – a count of total failed tests inside the hex Total – total tests attempted inside the hex Pass_percent – a ratio of passed tests to total tests inside the hex Download - (Download) speeds achieved during individual tests aggregated to H3 hexagon Upload - (Upload) speeds achieved during individual tests aggregated to H3 hexagon Jitter - variability in latency, or delay. Can be disruptive to audio communications. Jitter in milliseconds (ms) achieved during individual tests aggregated to H3 hexagon Latency - time delay in milliseconds (ms) achieved during individual tests aggregated to H3 hexagon Result – a descriptive text summary of results by download speed average across all tests inside the hex H3 – alphanumeric identifier for resolution 8 H3 hex## 项目说明 佛蒙特州移动无线路测项目是由佛蒙特州公共服务部电信与连通性分局牵头的专项举措，旨在评估该州境内沿线道路的移动语音与数据服务可用性及性能。本项目采用由消费级手机与专业软件组成的「测试套件」，以采集真实场景下的用户体验数据。该软件可记录移动服务可用性、宽带速率以及语音呼叫接通情况，所采集的数据能够识别已实现覆盖的区域，以及服务不可靠或完全缺失的区域。请注意，路测结果仅为某一时间点的「快照」，可能无法反映当前实际状况。 ## 数据说明 ### 数据测试总计 本多边形要素图层的数据源自2024年至2025年间开展的单次测速结果，并按H3分辨率8级六边形网格（H3 hexagon）进行汇总。本数据针对佛蒙特州境内的四家移动服务运营商采集：ATT、FirstNet、T-Mobile及Verizon。数据包含一个合并字段，涵盖对应六边形网格内所有已开展测试的结果。 本次测试数据包含项目期间所有已发起测试的采集结果，并具备以下属性字段： #### 测速统计字段架构 - **Vendor（运营商）**：被测移动服务提供商名称，包含ATT、FirstNet、T-Mobile、Verizon以及Combined（合并值） - **Pass（通过次数）**：该六边形网格内通过测试的总次数 - **Fail（失败次数）**：该六边形网格内失败测试的总次数 - **Total（总测试次数）**：该六边形网格内发起的测试总次数 - **Pass_percent（测试通过率）**：该六边形网格内通过测试次数与总测试次数的比值 - **Download（下载速率）**：单次测试所获下载速率，经聚合后得到对应六边形网格的数值 - **Upload（上传速率）**：单次测试所获上传速率，经聚合后得到对应六边形网格的数值 - **Jitter（抖动）**：时延（延迟）的波动程度，可能对音频通信造成干扰，单位为毫秒（ms），为单次测试结果聚合至六边形网格后的数值 - **Latency（时延）**：单次测试所获时间延迟，单位为毫秒（ms），经聚合后得到对应六边形网格的数值 - **Result（结果摘要）**：基于该六边形网格内所有测试的平均下载速率生成的结果文本摘要 - **H3**：H3分辨率8级六边形网格的字母数字标识符
