VT Data -2024/25 Drive Test - Voice Tests

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 Voice Tests This point feature layer features data collected from individual voice call 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. The test data includes results from each attempted test collected during the program and includes the following attributes: Voice Tests Schema Vendor - name of mobile service provider tested; includes ATT, FirstNet, T-Mobile, Verizon, and Combined values Result - a descriptive text summary of the results of each test Call_type - Type of call scenario (Mobile Origination or Mobile Termination) Technology - Cellular technology generation used at the time of test (4G, 5GNR, etc.) Start_time - Timestamp for the beginning of each call iteration End_time - Timestamp for end of each call iteration Traffic_time - Elapsed duration while UE was in active traffic exchange with the network for each test iteration Tsetup_time - Elapsed time to connect call once network connection is established Setup_time - Elapsed time for UE to establish connection with mobile network Latitude - Latitude associated with measurement location Longitude - Longitude associated with measurement location H3 – alphanumeric identifier for resolution 8 H3 hex### 项目说明 佛蒙特州移动无线路测项目（Vermont Mobile Wireless Drive Test Program）是由佛蒙特州公共服务部电信与互联互通司（Division of Telecommunications and Connectivity）牵头发起的一项举措，旨在评估佛蒙特州沿线道路的移动语音与数据服务的可用性与性能表现。本项目采用由消费级手机与专用软件组成的测试套件，以采集真实场景下的用户使用体验数据。该软件可记录移动服务可用性、宽带速率与语音通话接通情况，所采集的数据可识别出拥有信号覆盖的区域，以及服务不稳定或无服务的区域。请注意：路测结果仅为某一时间点的“快照”，未必能反映当前的实际服务状况。 ### 数据说明 #### 语音测试 该点要素图层（point feature layer）的数据来源于2024年与2025年开展的单次语音通话测试。本次数据采集覆盖佛蒙特州四家移动服务供应商：ATT、FirstNet、T-Mobile与Verizon。本次测试数据包含项目期间所有已发起测试的结果，具备以下属性字段： ##### 语音测试字段说明 - 供应商（Vendor）：被测移动服务供应商名称，可选值包括ATT、FirstNet、T-Mobile、Verizon以及“合并值” - 测试结果（Result）：单次测试结果的文本描述摘要 - 通话类型（Call_type）：通话场景类型，分为移动主叫（Mobile Origination）与移动被叫（Mobile Termination） - 通信技术（Technology）：测试时使用的蜂窝移动通信技术代次，如4G、5GNR等 - 开始时间（Start_time）：单次通话测试的起始时间戳 - 结束时间（End_time）：单次通话测试的结束时间戳 - 流量时长（Traffic_time）：单次测试中用户设备（UE, User Equipment）与网络进行主动流量交互的持续时长 - 通话建立时长（Tsetup_time）：网络连接建立后，完成通话接通的耗时 - 网络连接建立时长（Setup_time）：用户设备与移动网络建立连接的耗时 - 纬度（Latitude）：测试位置对应的纬度坐标 - 经度（Longitude）：测试位置对应的经度坐标 - H3：分辨率为8级的H3六边形网格（H3 hex）的字母数字标识符
